D, I have seen it vary. I think a better way to sell your management while
offering them flexibility is to make sure that your design process has an
owner accountable to the SI issues at planning, design execution and
verification. That owner might be the design lead, the group lead, or
dedicated SI resources. What I have seen work fairly well is to get as
much education into the troops up front as mandatory, and to make sure that
at least one person in any sizeable group has really in-depth knowledge or
retain consultants you trust for that role as advisors, reviewers, and
hopefully not very often, problem solver.
If you think of your design groups as manufacturers of designs, then it is
a Demming like concept to instill at least basic knowledge as a job
requirement into every design engineer, rather than rely on a dedicated
group. This also "just" makes a lot of the SI work part of the normal
design flow. So there isn't a visible large cost center creating budget
grief. JMO
Steve.
