<span style="font-family: Arial,Helvetica,sans-serif;">Fundamental to any PLM system is the idea of <b>Access Control and data security.</b> Only authorized personnel can access a PLM system and view or manipulate its contents. This is controlled via a login procedure that includes a user password. Personnel are added to the list of authorized users by the PLM administrator after someone has approved of their specific access rights.<br /><br />Once access has been granted to users, it must then be determined what operations they can carry out on the PLM system. <b>The simplest (and default) security model which allows all users to carry out any operation is very undesirable and could lead to actions that can destroy or leak vital data.</b><br /><br />This scenario requires the development of a Security model which determines which user can carry out which operations. Security models are normally based on two concepts:<br /><br />1. Roles<br /><br />2. Organizations<br /><br />A role in the database would define what the user who is assigned that role is allowed to do. Typical roles are as follows:<br /><br />1. Viewer – this role would be allowed to view data but not make any alterations or modifications<br /><br />2. Team Member – this role would be allowed to alter and update a limited subset of the data along with been able to carry out certain operations (e.g. initiate a workflow)<br /><br />3. Team Leader – this role would be able to do everything that a Team Member could do along with the ability to operate on a larger subset of data and carry out more operations (e.g. progress a workflow, change ownership)<br /><br />4. Approver – this role would be able to approve certain operations on the data (e.g. approve a release of information)<br /><br />5. Database Admin – normally limited to a handful of technically qualified people.<br />Once roles in a database have been defined, the organizations are put in place. These normally mirror actual organizational structure although this is not a necessity. Organizations in a PLM system usually work on specific projects or programs. Once the organization is defined, users are allocated to various organizations and are assigned specific roles.<br /><br />The final result can be represented in a table as follows:</span><br />

shows that this can be applied to far more complex situations. If setup
correctly, a PLM system can very quickly generate BOM’s for multiple variants.
In an organization faced with the challenge of product proliferation, this can
be very efficient compared to any other method.</span></span></div>
<div class="MsoNormal">
<br /></div>
<span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;">
</span></span><br />
<div class="MsoNormal">
<span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;">In setting up such structures, a few general guidelines
apply:</span></span></div>
<div class="MsoNormal">
<br /></div>
<ol style="text-align: left;">
<li><span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;"></span></span><span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;"><span style="-moz-font-feature-settings: normal; -moz-font-language-override: normal; font-size-adjust: none; font-stretch: normal; font-style: normal; font-variant: normal; font-weight: normal; line-height: normal;"></span>The conditional links in the BOM should be
applied as far down the structure as possible. This reduces common part
duplication in lower levels</span></span><span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;"> </span></span></li>
<li><span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;"><span style="-moz-font-feature-settings: normal; -moz-font-language-override: normal; font-size-adjust: none; font-stretch: normal; font-style: normal; font-variant: normal; font-weight: normal; line-height: normal;"></span>Conditional links should be set at the same
indent level in the BOM hierarchy. If this is not done, BOM resovles can lead
to nonsensical results, especially if there are stacked conditionals</span></span></li>

<span style="font-family: Arial,Helvetica,sans-serif;">One of the major problems facing any manufacturer of physical product is the issue of variations. Typically a manufacturer is faced with a dichotomy: customers want infinite variations in what they can buy but a manufacturing process is most efficient when it is only making on specific product. This problem is seen across many industries, especially where the production model is based on make-to-order.</span><br />
<span style="font-family: Arial,Helvetica,sans-serif;"><br />As an example, consider a pickup truck. It has been estimated that by time one takes into consideration all of the exterior colors (maybe 10), interior colors (maybe 5), powertrain possibilities (maybe 3), trim levels (maybe 5), sunroof or not, premium sound system or not, towing package etc. there are over 100,000 buildable combinations. Such large numbers are the inescapable consequence of mathematics; combinations are multiplicative and grow exponentially in a way similar to the factorial function used to calculate odds.</span><br />
<span style="font-family: Arial,Helvetica,sans-serif;"><br />As with a lot of PLM terminology, some confusion exists with regard to definitions and so this article will use the following definitions: </span><br />
<ol style="text-align: left;">
<li><span style="font-family: Arial,Helvetica,sans-serif;"> A <b>configuration</b> is a specific grouping of parts or components that achieves a certain function within an overall product</span></li>
<li><span style="font-family: Arial,Helvetica,sans-serif;">A <b>variant </b>is a <b>single </b>option within an overall product family</span></li>
<li><span style="font-family: Arial,Helvetica,sans-serif;">A <b>variant </b>is a <b>combination </b>of specific configurations of parts or components</span></li>
</ol>
<span style="font-family: Arial,Helvetica,sans-serif;"> </span><span style="font-family: Arial,Helvetica,sans-serif;">Consider the following example:</span><br />
<div>
<span style="font-family: Arial,Helvetica,sans-serif;"></span><br />
<ol style="text-align: left;">
</ol>
<div class="separator" style="clear: both; text-align: center;">

<span style="font-family: Arial,Helvetica,sans-serif;"></span><br />
<span style="font-family: Arial,Helvetica,sans-serif;"></span><br />
<span style="font-family: Arial,Helvetica,sans-serif;"><br />In the above structure, a distinction is made between a spectacle with a fancy frame or a plain frame. However the lenses and frame arms are common across both variants.</span><br />
<span style="font-family: Arial,Helvetica,sans-serif;"><br />This simple example illustrates the power of variant designs; the customer now has two choices but the manufacturer has a many common parts across the two products. </span><br />
<br />
<span style="font-family: Arial,Helvetica,sans-serif;">So, how to harness these advantages in PLM system? That will be covered in the next post.</span><br />

<span style="font-family: Arial,Helvetica,sans-serif;">Among technology practitioners there is no shortage of pundits offering predictions of the future and where the next big wave is going to hit. The reason for this is that the stakes are high – a correct forecast of future technology trends can literally be worth billions.<br />So what are the current predictions talking about? Here is a sampling of the current buzz:</span><ol style="text-align: left;">
<li><span style="font-family: Arial,Helvetica,sans-serif;"> Big Data</span></li>
<li><span style="font-family: Arial,Helvetica,sans-serif;"> Social Media</span></li>
<li><span style="font-family: Arial,Helvetica,sans-serif;"> Crowd Sourcing</span></li>
<li><span style="font-family: Arial,Helvetica,sans-serif;"> Social Computing</span></li>
<li><span style="font-family: Arial,Helvetica,sans-serif;"> Mobile Connectivity</span></li>
</ol>
<span style="font-family: Arial,Helvetica,sans-serif;">So how does this impact PLM? Traditionally PLM is conducted on internal infrastructure in secured environments using traditional devices. For example, an average designer concerned with the creation of a 3D CAD data would be working on a company workstation behind a firewall. Equally, an engineer creating BOM data would be using a secured client install on his company laptop. The possibility exists that the engineer may take his laptop home and interact with the PLM system via a VPN but this is probably the extent of “mobility.”</span><br />
<span style="font-family: Arial,Helvetica,sans-serif;"><br />Returning to the technology buzz, consider the potential impact of two trends – mobile connectivity and social computing. Consider the following scenarios:<br /><br />Your newly recruited engineer has transitioned his digital life to his tablet and no longer uses a laptop. (hence the title of this piece)</span><br />
<span style="font-family: Arial,Helvetica,sans-serif;"><br />The VP of Engineering wants to query the status of his product introduction using his mobile phone<br />Your company wants immediate access to customer feedback on existing products so that this can be translated into requirements for new or updated designs<br /><br />Given the traditional model sketched our earlier, implementing anything close to these scenarios is almost impossible. The infrastructure, mindset and processes will not support mobile connectivity from alternative devices nor allow general access to a requirements gathering front end. Also, it raises a whole lot of questions around data security, use of private devices and non-company access. While the technology to achieve these scenarios probably exists, it would require considerable financial and effort investment to make it happen.</span><br />
<div style="text-align: left;">
<span style="font-family: Arial,Helvetica,sans-serif;"><br />This leads to the fundamental risk investment equation. It may be possible to construct a business case that justifies the outlay. At a high level, two possibilities exist:</span></div>
<ol style="text-align: left;">
<li><span style="font-family: Arial,Helvetica,sans-serif;">Traditional PLM infrastructure is good enough for at least the next ten years and can be re-evaluated then</span></li>
<li><span style="font-family: Arial,Helvetica,sans-serif;">Changing the way business is conducted is a do or die activity and this includes PLM</span></li>
</ol>
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgVIJVKWqv51OUv1NmFe_PoIEmxcxt_31UPCeWqs3LLIJPCid7oXHfg1bNv4VeQleAtTZWk-dZVVmyxI-3B_qMTmzsIVNt5H-Z1-o7siA-FsUsTFo6-FICmCyD-kr4GzjbvtbOl_lY862PY/s1600/twitter-icon.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"></a></div>

<span style="font-family: Arial,Helvetica,sans-serif;">An informal survey of small to medium size companies shows that most participants have not even considered these technology trends. In part, there appears to be no business imperative and in part because there are other more attractive avenues for immediate investment.<br /><br />So, do you want your engineers to be doing all their engineering work on a tablet?<br /></span></div>

<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Arial,Helvetica,sans-serif;">It must be said that understanding how a BOM functions is
fundamental to understanding how PLM systems work as this simple list is really
at the core of the system. However, simple concepts have a tendency to escalate
into very complex subjects. And so it is with a BOM.</span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Arial,Helvetica,sans-serif;">One of the complexities associated with a BOM is that an
organization usually has a requirement for different types of a BOM in order to
define a single product. Most manufacturing companies have at least three
types:</span></div>
<br />
<ol style="text-align: left;">
<li><span style="font-family: Arial,Helvetica,sans-serif;"><b><span style="mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin;"><span style="mso-list: Ignore;"><span style="-moz-font-feature-settings: normal; -moz-font-language-override: normal; font-size-adjust: none; font-size: 7pt; font-stretch: normal; font-style: normal; font-variant: normal; font-weight: normal; line-height: normal;"></span></span></span>EBOM </b>(Engineering BOM) is the list of parts that
engineers are responsible for and comprises all the components that require
some sort of design input<br /></span></li>
<li><span style="font-family: Arial,Helvetica,sans-serif;"><b><span style="mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin;"><span style="mso-list: Ignore;"><span style="-moz-font-feature-settings: normal; -moz-font-language-override: normal; font-size-adjust: none; font-size: 7pt; font-stretch: normal; font-style: normal; font-variant: normal; font-weight: normal; line-height: normal;"></span></span></span>MBOM </b>(Manufacturing BOM) is the list of parts
that are required to actually make the product. This is typically different
from EBOM by components that engineering do not specifically design (glue
strips, liquid fills etc.). It may also be plant specific.<br /></span></li>
<li><span style="font-family: Arial,Helvetica,sans-serif;"> <b>XBOM </b>(Service BOM) is an as built list of parts
used in a product that actually made it off the factory floor. This may be
different from what was originally specified by the MBOM because of crisis
during manufacture. It is important from a customer service perspective.</span></li>
</ol>
<br />
<div class="MsoListParagraphCxSpLast" style="mso-list: l1 level1 lfo1; text-indent: -.25in;">
<span style="font-family: Arial,Helvetica,sans-serif;"></span></div>
<span style="font-family: Arial,Helvetica,sans-serif;"><b>So the question is – how are your three BOMs authored,
edited, maintained and released?</b> Whatever the answer to this question, the
outcome is always the same:</span>
<br />
<ol style="text-align: left;">
<li><span style="font-family: Arial,Helvetica,sans-serif;"><span style="mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin;"><span style="mso-list: Ignore;"><span style="-moz-font-feature-settings: normal; -moz-font-language-override: normal; font-size-adjust: none; font-size: 7pt; font-stretch: normal; font-style: normal; font-variant: normal; font-weight: normal; line-height: normal;"></span></span></span>No BOM – No product<br /></span></li>
<li><span style="font-family: Arial,Helvetica,sans-serif;"><span style="mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin;"><span style="mso-list: Ignore;"><span style="-moz-font-feature-settings: normal; -moz-font-language-override: normal; font-size-adjust: none; font-size: 7pt; font-stretch: normal; font-style: normal; font-variant: normal; font-weight: normal; line-height: normal;"></span></span></span>Wrong BOM – Factory rework or customer dissatisfaction.</span><span style="font-family: Arial,Helvetica,sans-serif;"> </span></li>
</ol>
<span style="font-family: Arial,Helvetica,sans-serif;">An informal survey of small to medium size companies yields
surprising results: Excel is the predominant BOM management tool in an
engineering environment. Manufacturing BOMs are normally handled by some sort
of ERP system and service BOMs are poorly tracked, if at all. This situation is
fraught with potential for disaster because of all the manual processes that
have to occur before an actual product gets made.</span><div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Arial,Helvetica,sans-serif;">Hence the analogy in the title; BOM management may be a
hidden problem that is set to explode in an organization, especially if the
products been made become more complex. PLM systems can offer a single
organized BOM that represents all the different types in a consistent,
controlled manner. Given the potential consequences of the bomb exploding, BOM
in PLM should be a priority.</span></div>

<span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;">Fundamental to any manufacturing organization, and by
extension its PLM system, is the part number. This is a unique identifier for
any end component used in a manufacturing process.
<br />
</span></span><br />
<div class="MsoNormal">
<span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;">Anyone who has dealt with part numbers is familiar with the
so called "intelligent part number". To an extent, this is a
carryover from the days before sophisticated database systems and fast
computers. It involves baking multiple pieces of information into single part number.</span></span></div>
<div class="MsoNormal">
<span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;"><br />For example, consider the fictitious case of the omnipresent
widget and assume that it has a Part Number built up as follows:</span></span></div>

<div class="MsoNormal">
<span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;">Initially, the structure of the number seems perfectly
logical and in keeping with our concept of what part numbers should look like.
However, a more detailed analysis will diagnose some (but not all) potential
problems:</span></span></div>
<br />
<ol style="text-align: left;">
<li><span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;"><span style="-moz-font-feature-settings: normal; -moz-font-language-override: normal; font-size-adjust: none; font-stretch: normal; font-style: normal; font-variant: normal; font-weight: normal; line-height: normal;"></span>Clearly, a transition into the 21<sup>st </sup>Century
is a problem for the first two digits of the number</span></span></li>
<li><span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;">The 1001<sup>th</sup> part will not be able to
fit</span></span></li>
<li><span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;"><span style="-moz-font-feature-settings: normal; -moz-font-language-override: normal; font-size-adjust: none; font-stretch: normal; font-style: normal; font-variant: normal; font-weight: normal; line-height: normal;"></span>The enterprise expands its manufacturing base
offshore and wants to introduce country codes</span></span></li>
</ol>
<br />
<div class="MsoNormal">
<span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;">If the intelligent part number is the key attribute in the
database, the problem rapidly compounds. This is because it is extremely
difficult to change the key attribute in a database once objects have been
created and included in multiple relationships.</span></span><br />
<span style="font-family: Arial;"></span> </div>
<div class="MsoNormal">
<span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;">So what is the alternative to intelligent part numbers? The
prudent alternative is to set up non-key attributes in the database that
contain the information previously baked into the part number. Once this is
done, the part number for objects can be a randomly allocated sequence of
digits.</span></span><br />
</div>
<div class="MsoNormal">
<span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;">This may sound counter intuitive but, in the long run, will
save a lot of heartache.</span></span><br />

<span style="font-family: Arial,Helvetica,sans-serif;"><b>In keeping with the spirit of the season, why not set out a
wish list for PLM? If we sent it off to the North Pole, perhaps some of them
would come to fruition.</b></span></div>
<span style="font-family: Arial,Helvetica,sans-serif;">
</span><br />
<div class="MsoNormal">
<span style="font-family: Arial,Helvetica,sans-serif;">Before we define the list, let’s set out a few objectives of
PLM so that we clearly understand what we are trying to achieve before we wish
for our imagined gifts. The following is an incomplete list but sometimes these
objectives are lost in the daily struggle for survival lost in the technology:</span></div>
<span style="font-family: Arial,Helvetica,sans-serif;">
</span><br />
<ol style="text-align: left;">
<li><span style="font-family: Arial,Helvetica,sans-serif;"><span style="mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin;"><span style="mso-list: Ignore;"><span style="-moz-font-feature-settings: normal; -moz-font-language-override: normal; font-size-adjust: none; font-size: 7pt; font-stretch: normal; font-style: normal; font-variant: normal; font-weight: normal; line-height: normal;"></span></span></span>Store data in a secure and controlled manner</span></li>

<li><span style="font-family: Arial,Helvetica,sans-serif;"><span style="mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin;"><span style="mso-list: Ignore;"><span style="-moz-font-feature-settings: normal; -moz-font-language-override: normal; font-size-adjust: none; font-size: 7pt; font-stretch: normal; font-style: normal; font-variant: normal; font-weight: normal; line-height: normal;"></span></span></span>Pass unambiguous and correct information to a
manufacturing process</span></li>
</ol>
<div class="MsoNormal">
<span style="font-family: Arial,Helvetica,sans-serif;">Based on the above, here is a list of PLM moves that many
organizations could make with small investment and good returns:</span></div>
<span style="font-family: Arial,Helvetica,sans-serif;">
</span><br />
<ul style="text-align: left;">
<li><span style="font-family: Arial,Helvetica,sans-serif;"><span style="mso-list: Ignore;"><span style="-moz-font-feature-settings: normal; -moz-font-language-override: normal; font-size-adjust: none; font-size: 7pt; font-stretch: normal; font-style: normal; font-variant: normal; font-weight: normal; line-height: normal;"></span></span><i style="mso-bidi-font-style: normal;">Free 3D
viewers</i> – In the spirit of collaborative design, it is strange how many
organizations have a PLM system that only allows CAD designers to view 3D
geometry. This leads to scenarios were other participants in the design process
have to find a cooperative CAD designer to interrupt his current task and “pull
up the geometry.” Long discussions can then ensue around design issues exposed
by the geometry. Is this productive? – No. Many of the PLM vendors provide free
3D viewers that can be deployed to all participants in the design process. Some
infrastructure may be required to create the correct file formats; but a for a
small investment, CAD designers can focus uninterrupted on their business.
Imagine the productivity gains!<span style="mso-list: Ignore;"> </span></span></li>
</ul>
<ul style="text-align: left;">
<li><span style="font-family: Arial,Helvetica,sans-serif;"><span style="mso-list: Ignore;"><span style="-moz-font-feature-settings: normal; -moz-font-language-override: normal; font-size-adjust: none; font-size: 7pt; font-stretch: normal; font-style: normal; font-variant: normal; font-weight: normal; line-height: normal;"> </span></span><i style="mso-bidi-font-style: normal;">Ban Excel
BOMS</i> – Central to any organization that manufactures tangible goods is a
Bill of Material. Without this information, nothing would leave the factory. In
addition, BOM information usually feeds multiple downstream processes from
procurement to service to ERP systems. So, why keep this vital information in a
general software tool like Excel that is not designed to perform this function?
In addition, the security and access controls that can be achieved are
definitely deficient. For a modest investment, one can install a PLM system that
has a robust and targeted BOM system designed to deliver correct and complete
information to an organization.</span></li>
</ul>
<ul style="text-align: left;">
<li><span style="font-family: Arial,Helvetica,sans-serif;"><span style="mso-list: Ignore;"><span style="-moz-font-feature-settings: normal; -moz-font-language-override: normal; font-size-adjust: none; font-size: 7pt; font-stretch: normal; font-style: normal; font-variant: normal; font-weight: normal; line-height: normal;"></span></span><i style="mso-bidi-font-style: normal;">Close down
FTP sites</i> – There is no denying FTP is a very useful piece of software that
has multiple applications, but it requires multiple manual interventions to be
successful and can potentially be a security risk. If you drilled into any
organization, there would probably be a few FTE equivalents of time spent using
FTP. Modern PLM systems can offer many alternatives to this method of data transfer:
collaboration servers, web portals, cache systems, or automated mailboxes are
some examples. Looking for a good ROI opportunity? – close your FTP site. </span></li>
</ul>
<ul style="text-align: left;">
<li><span style="font-family: Arial,Helvetica,sans-serif;"><span style="mso-list: Ignore;"><span style="-moz-font-feature-settings: normal; -moz-font-language-override: normal; font-size-adjust: none; font-size: 7pt; font-stretch: normal; font-style: normal; font-variant: normal; font-weight: normal; line-height: normal;"></span></span><i style="mso-bidi-font-style: normal;">Automate
PLM to ERP transfer </i>– Typically, a BOM and related information is created
in the PLM environment and then transferred to an ERP system for manufacture.
Odds are that this transfer is entirely manual or, if partially automated,
requires significant manual intervention. All manual interventions are prone to
error and manufacturing errors are always costly. So why not put some effort
into automating this crucial organizational interface? </span></li>
</ul>
<span style="font-family: Arial,Helvetica,sans-serif;">
</span><br />
<div class="MsoNormal">
<span style="font-family: Arial,Helvetica,sans-serif;">Are there additional items that could be added to the wish
list? Have a look in your organization and the list will grow.</span></div>

<div class="MsoNormal">
<span style="font-family: Arial,Helvetica,sans-serif;">You have a PLM system. Fundamental to this system is the
concept of a version and a revision. However, it is probably the most
misunderstood process in the PLM realm. Also these terms mean a wide variety of
things to different people and are often used interchangeably and without
consistency.</span></div>
<div class="MsoNormal">
<span style="font-family: Arial,Helvetica,sans-serif;"><br /></span></div>
<div class="MsoNormal">
<span style="font-family: Arial,Helvetica,sans-serif;">For the purposes of the rest of this piece, we will use the
following definitions:</span></div>
<div class="MsoNormal">
<span style="font-family: Arial,Helvetica,sans-serif;"><br /></span></div>
<div class="MsoNormal">
<span style="font-family: Arial,Helvetica,sans-serif;"><i style="mso-bidi-font-style: normal;">Version</i> –
represents a small incremental change in the design that would be saved in the
database. Versions are not necessarily saved permanently beyond a revision.</span></div>
<div class="MsoNormal">
<span style="font-family: Arial,Helvetica,sans-serif;"><i style="mso-bidi-font-style: normal;">Revision</i> –
represents a significant event in the design process and is saved permanently
in the database for reference throughout the design process. </span><br />
<br />
<span style="font-family: Arial,Helvetica,sans-serif;">Diagrammatically, the difference is illustrated by the

<div class="MsoNormal">
<span style="font-family: Arial,Helvetica,sans-serif;">It is often confusing to talk to about this subject because
the terms are used interchangeably. Also, the clear distinction between a
version and a revision is not clearly understood; even to the extent that
participants think that they are the same thing. Because of this, it is
important that any organization with a PLM system ensure that all the
participants clearly understand the definition and what the difference is.</span></div>
<div class="MsoNormal">
<span style="font-family: Arial,Helvetica,sans-serif;"><br /></span></div>
<div class="MsoNormal">
<span style="font-family: Arial,Helvetica,sans-serif;">In a collaborative PLM environment, participants are very
dependent on viewing or using data generated by other participants. For
example, a headlamp engineer needs the position of locating holes in the sheet metal
to be able to design his locating pins (if this is the order of precedence). In
this scenario, the headlamp engineer will say “I need the latest sheet metal to
begin my design.” This statement is common in design and engineering teams.
However, it is inherently imprecise because it begs the question: Do you need
the latest version or latest revision?</span></div>
<div class="MsoNormal">
<span style="font-family: Arial,Helvetica,sans-serif;"><br /></span></div>
<div class="MsoNormal">
<span style="font-family: Arial,Helvetica,sans-serif;">Based on the definition given earlier, what is really
required is the latest revision. A version is work in progress and could be
incomplete or half done because the responsible author may be in the middle of
a redesign or new concept. For this reason, a version should not be visible to
the larger organization, only revisions should be accessible as they satisfy
the definition of “best so far.” This concept is very difficult to get across
to a lot of people and represents the conundrum referred to in the title. It
takes some courage to work on data that will change sometime in the future but
this is absolutely required in an efficient design process.</span></div>
<div class="MsoNormal">
<span style="font-family: Arial,Helvetica,sans-serif;"><br /></span></div>
<div class="MsoNormal">
<span style="font-family: Arial,Helvetica,sans-serif;">The version revision conundrum also leads to some
interesting human psychology. Consider any collaborative design environment
where multiple participants have to submit data into a PLM system to progress a
large project. It is important in these environments that all participants
follow the mantra of “publish early, publish often” or in the nomenclature of
this piece: create many revisions. This is based on the principle that incomplete
or slightly inaccurate data is better than no data at all.</span></div>
<div class="MsoNormal">
<span style="font-family: Arial,Helvetica,sans-serif;"><br /></span></div>
<div class="MsoNormal">
<span style="font-family: Arial,Helvetica,sans-serif;">However, process managers often put in systems that
highlight inaccuracies or incomplete data, effectively punishing early
publishers. So data authors hold back and only create revisions when they are
certain of accuracy, late in the process. This is counterproductive.</span></div>
<div class="MsoNormal">
<span style="font-family: Arial,Helvetica,sans-serif;"><br /></span></div>
<div class="MsoNormal">
<span style="font-family: Arial,Helvetica,sans-serif;">So, pay attention to the version revision conundrum; clear
definitions and policies of this simple issue can greatly improve a PLM
process.</span><br />

<h2 style="text-align: left;">
</h2>
<div style="text-align: left;">
<span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;">So your company has embarked on the PLM journey. Strategy is agreed, budget is approved, the preliminary plan for execution is in place and Return on Investment (ROI) has been computed.<br /><br />The next step in the process is choosing a software suite and an associated vendor. Unfortunately, the nature of software is such that one cannot mix and match programs or modules to suit specific requirements; the major vendors design their solutions is such a way that organizations are locked into a specific monolithic offering. The choice of vendor, then, has long term ramifications, and, on the face of it appears to be a momentous decision.<br /><br />So, how does one choose a PLM technology vendor? For the purposes of answering, let us submit two potential techniques:</span></span></div>
<ol style="text-align: left;">
<li><span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;">Undertake a comprehensive study to evaluate the merits of each vendor's solution against requirements, conduct benchmarks and produce recommendations (The Bake Off)</span></span></li>
<li><span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;">Meet in the main boardroom of the company, ensure attendance of auditors and all interested parties and toss a coin to decide which vendor to choose (The Coin <span style="font-size: small;">T</span>oss)</span></span></li>
</ol>
<span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;">Before debating the merits and demerits of each technique, it is instructive to outline a methodology for the bake off option. The high level steps required to conduct a study are as follows:</span></span><br />
<ol style="text-align: left;">
<li><span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;">Outline business imperatives and goals (e.g. global engineering)</span></span></li>
<li><span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;">Identify the PLM processes that have to be put in place or facilitated to meet these goals (e.g. extended design reviews)</span></span></li>
<li><span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;">Create use cases to illustrate the processes (e.g. ability to load complete product into webex session and have geographically dispersed teams critique)</span></span></li>
<li><span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;">Evaluate each technology against the use case and score its capability to support the use case (e.g. how long does it take to load a product into a review session)</span></span></li>
<li><span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;">Total up all the scores and make a recommendation.</span></span></li>
</ol>
<span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;">Clearly the <span style="font-size: small;">B</span>ake Off would be the conventional business approach. It offers the advantages of rigor, objectivity and a comprehensive approach. By following the evaluation methodology, an organization is guaranteed of having a technology that supports its needs.<br /><br />So why even consider the <span style="font-size: small;">C</span>oin <span style="font-size: small;">T</span>oss? Any business person worth his salt would recoil at the thought of employing such a sloppy and unscientific method. But before dismissing this out of hand, consider a few items. Firstly, technology changes at an alarming pace and what is good today in one vendors solution will be outpaced by next year’s release. Secondly, the tough part of PLM implementations is managing organizational change and this has nothing to do with technology. Thirdly, agonizing over decisions is probably worse than making a snap decision – fortune favors the bold.<br /><br />So consider the Coin <span style="font-size: small;">T</span>oss or a at least a compressed <span style="font-size: small;">B</span>ake <span style="font-size: small;">O</span>ff; it can certainly save time and maybe allow an organization to leap ahead of its competition.</span></span></div>

<span style="font-size: x-large;"><span style="font-family: Verdana,sans-serif;">Who invented PLM?</span></span></h2>
<br /><span style="font-family: Arial,Helvetica,sans-serif;">In keeping with the past dimension of this blog’s mission, perhaps it is important to ask the question: <b>who invented Product Lifecycle Management (PLM)</b>?<br /><br />On the face of it, this may seem a frivolous question, but if it is legitimate, the answer does have implications for the usage in the industry. Consider a quotation on this question by Carl Bass of Autodesk (search YouTube for “Carl Bass anti-PLM rap”) in which he states that the only companies with a PLM problem are Dassault Systèmes, PTC and UGS (now Siemens PLM).<br /><br />So, this leads one to pay more attention to the question and formulate two potential answers:</span><ol>
<li><span style="font-family: Arial,Helvetica,sans-serif;">PLM was invented by the vendors as a strategy to scare manufacturing customers into buying expensive software (push model)<br /></span></li>
<li><span style="font-family: Arial,Helvetica,sans-serif;">PLM was an industry competitive imperative and software vendors are fulfilling a genuine need (pull model)</span></li>
</ol>
<span style="font-family: Arial,Helvetica,sans-serif;"><b>If your preference is for the push model, then organizations should be looking seriously at their so-called “PLM strategy” and questioning what they really need.</b> Does the ability to tie together all product data from conception to manufacture actually improve business? Or is it better to deploy targeted software at strategic points in the design process where it can be clearly demonstrated that this brings efficiencies?<br /><br />There are a couple of proof points that tend to answer the questions above in favor of the push model. Firstly, many large, successful companies who are considered industry leaders often have a <i>patchwork of software solutions that don’t actually tie product data together</i>. If it was a business imperative, this situation would not exist. Secondly, it is well known that some PLM implementations do not succeed, but do not necessarily result in taking the company out of business. Finally, PLM software vendors will often have a core product that generates most of their profits and the rest of their “strategic” offerings are not widely adopted.<br /><br />Alternatively,<b> if your preference is for the pull model, then organizations best be focused on a PLM strategy or else they will be out of business</b>. There is evidence that supports this view. Firstly, organizations have increased productivity dramatically, and there is an explosion of consumer choices for physical products. Secondly, consider the automobile of today compared to 20 years ago and compare the level of sophistication. Finally, one can look at the revenue growth of PLM software vendors and extrapolate this into a real need by industry.<br /><br />Perhaps the pragmatic answer lies somewhere in between the two extremes. PLM as conceived by the strategists is actually only a vision and by definition unobtainable. So while it is important to keep it in mind, <b>companies are better served by critically examining processes and implementing technology where it makes sense for their business.</b></span><br />Tata_Technologieshttp://www.blogger.com/profile/13356015839439891001noreply@blogger.com0
