Chuck, is this aircraft development (new) or aircraft modification? By “Basing” I presume where the aircraft is located/(airport, militarybase, etc.)?
Regardless, there has to be a structure of the work defined to assign resources and to track performance. Do you have this structure in place? As I mentioned previously, is there a Work Breakdown Structure defined? If development, all aircraft work would be similar, other than modifications. If a modification effort, then not all aircraft may be undergoing the same work flow, but the WBS would accomodate which systems are being overhauled and repaired, hence, my question.
To reiterate what Larry mentioned, what data are you intending to get out of this, and how are you planning on managing the work=?
