1.6.3 Type 3: Approach
Approach is the systems engineering that every engineer must perform on the product, including understanding risks, understanding the operational need, clarifying requirements before jumping to a solution, doing at least informal trade studies to make decisions, and so on through the process or focus areas of the chosen capability model.  This is the kind of systems engineering that translates to toasters and cell phones. It is different from coordination or management as in Program Systems EngineeringApproach is what the individual engineer does. Approach is the set of life-cycle roles as applied on a small project or as implemented on a small, commercial development project.
