In addition, with a built-in bias towards the Process industry, the concept of Just-in-Time has<br />
probably not been even considered, due to its use primarily within the D<strong>is</strong>crete manufacturing<br />
industry.<br />
Some manufacturers face extreme regulatory requirements, based on their particular industry<br />
or vertical, each of which <strong>is</strong> highly unique to their respective industry. For example, firms<br />
operating within the Defense or Medical Device industries face a myriad of regulations and<br />
regulatory reporting requirements necessitating unique auditing, reporting, electronic signature<br />
and other approval documentation requirements. Their plant to enterpr<strong>is</strong>e integration must<br />
include special capabilities to meet regulatory requirements for product h<strong>is</strong>tories with operator<br />
sign-offs, so as to be ready for government auditors.<br />
Maintain Operational and Data Integrity<br />
It <strong>is</strong> common for an ERP system to go down for several hours at a time for maintenance,<br />
system upgrades or just unplanned outages. Depending upon how critical 24x7 operations are<br />
within your unique production environment will have a big impact on whether or not th<strong>is</strong> type of<br />
d<strong>is</strong>ruption <strong>is</strong> acceptable or not. Consequently, your plant to enterpr<strong>is</strong>e integration design must<br />
also reflect th<strong>is</strong> operational reality, assigning the appropriate operations to the right Layer<br />
within the <strong>ISA</strong>-<strong>95</strong> hierarchy. Select MOM vendor solutions can operate autonomously if Level<br />
4 connectivity <strong>is</strong> severed; others can’t.<br />
Organizational Responsibilities<br />
Clearly, the <strong>is</strong>sue of what group maintains the integrity and security of the plant-to-enterpr<strong>is</strong>e<br />
integration architecture <strong>is</strong> an important one for a company to decide. Once again, the<br />
allocation of th<strong>is</strong> duty <strong>is</strong> not explained within the <strong>ISA</strong>-<strong>95</strong> standards, nor should it.<br />
When dealing with personnel <strong>is</strong>sues and the assignment of duties and responsibilities, several<br />
local and global factors are at work, each of which could vary considerably based on the<br />
governance models at each firm. While some companies will assign th<strong>is</strong> responsibility to<br />
manufacturing IT, others might deem th<strong>is</strong> as within the domain of corporate IT, manufacturing<br />
operations or product engineering.<br />
