We Re-evaluate

We Re-evaluate

Re-evaluate is arguably the most important of these functions. For a century, engineers have used feedback to help control systems and improve performance. It is one of the most fundamental engineering tools. Re-evaluation should be a continual process with many parallel loops. Re-evaluate means observing outputs and using this information to modify the system, the inputs, the product or the process. Figure 1 summarizes the Systems Engineering Process. This figure clearly shows the distributed nature of the Re-evaluate function in the feedback loops. However, all of these loops will not always be used. The particular loops that are used depend on the particular problem being solved.
