In Part 1, the D•I•P•O•D Process Model and template were presented and explained. In this installment, an example deployment will be illustrated to demonstrate the variety of factors to be considered in an analysis. Practitioners are warned against developing a false sense of security or accomplishment in a special note on troubleshooting. Then, a number of common errors will be shared to help practitioners avoid them.
Well-designed models can be invaluable aids to development and analysis. 3D CAD models assist the detection of physical interferences in an assembly and the rapid calculation of stresses within its components. Mold-flow analysis helps injection molders predict processing problems. Various forms of simulation help us evaluate potential performance and identify risks before any products are manufactured, tooling built, routes established, or services performed.
Successful process planning, troubleshooting, and continuous improvement begins with applying fundamentals. Therefore, a model need not be as sophisticated as mold-flow or finite-element analysis requires to be useful, nor does it require high-performance computers with extensive computational capability. For many purposes, a simple diagram can provide the guidance needed for users to achieve breakout performance by focusing attention on what is relevant to the achievement of objectives, while clearing the clutter of distractions. The D•I•P•O•D Process Model is a great example of effective simplicity when used for process planning, development, or troubleshooting.
