If, after considering the advantages and disadvantages, you decide to use model programs, the following steps should be followed ... 

FIGURE 6-4. Simplified Example of Adaptation of a Model Program... 

Understand the model. Review the model program and develop an understanding of how it really works. It is often useful to draw a flow chart of the model process to be sure you completely understand it. 

Reconcile the model with existing roles and responsibilities. Each role called for in the model program will have to be filled by someone in your organization. What are the roles and responsibilities required To whom will they be assigned ... 

Reconcile the resource requirements. The model program will involve some time requirements and may also call for some materials or information. Determine how the time will be made available, and where the materials and information will come from, before trying to use the model program. 

Beware the temptation to adopt model programs wholesale. Before installing... 

Using model programs offers the advantage of efficiency. Installation can be accomplished relatively quickly, often with minimal investment of staff time. Since model programs evolve from the experience of others, many of their kinks have already been worked out, which can facilitate implementation. 

At the same time, relying on model programs has its share of pitfalls, in large part because a PSM system cannot succeed unless it can be properly integrated into the management systems in place for other activities. By definition a model program reflects the specific needs, operations, and practices of a given company, all of which may be quite different from your own. 

A related limitation of the model program approach is that these "transplants" rarely take full advantage of opportunities to link PSM into other company systems, for example, using existing human resources systems to manage process safety-related training. 

Use model programs to trigger ideas and focus or expedite the systems design effort. Look for opportunities to learn from the experience of others, but in most cases try to emphasize adapt" rather than adopt ... 

A key advantage of the business process redesign approach is that while it draws on past experience (in the form of the team s collective expertise) it is not bound by it. This helps minimize the risk that inadequate practices may become institutionalized through habit or neglect, and forces the team to take a fresh look at the critical processes under review. At the same time, this approach requires more concentrated effort than either TQM or model programs and may not be necessary in cases where incremental improvement is all that s required to address PSM gaps. 

What Is the Expected Process for Their Work. This requires a clear presentation of the approach (TQM, process redesign, model programs, other), which will to some extent dictate the working process. In addition, specifics about team leadership, the role (if any) of facilitators or advisors. 

A Simple Model for The Reaction. Several models have be en developed for the self-condensation of A. CSMP (Continuous System Modeling Program) programming has been used to integrate numerically the set of differential equations associated with each model and to calculate methylol and methylene ether group concentrations as a function of time.
