- From:
- AUSROC II : A Post Mortem
- ~~~~~~~~~~~~~~~~~~~~~~~~~
- Tzu-Pei Chen
-
- "The design of AUSROC II was in many ways too "positive".
- Much thought had been put into each of the systems, but
- little thought had been allocated to possible failures and
- their consequences. Obviously, greater testing of each
- component may have shown up some of these problems earlier.
- This simply highlights the very limited resources with which
- the group currently works. The six static firings were in
- themselves, major system tests, but they were already a
- major strain on our resources. Hopefully AUSROC II-2 will be
- able to proceed in an environment where financial and man-
- hour constraints become secondary to the process of
- engineering."
-
- Here is an example of what can go wrong with "fast track" programs
- where too positive an outlook leads to overlooking simple, and
- in 20/20 hindsight, obvious problem areas. The problems were
- only obvious in hindsight, however, which is the main risk of
- a success oriented program. Pegasus' teething problems stem
- from a similar outlook. As Chen notes, financial and manpower
- requirements for adequate engineering studies and testing for
- the project were overly optimistic leading to complete vehicle
- loss and a major financial and schedule loss to the project.
-
- We hope they'll be able to muster the financial and manpower
- requirements to do the job right the next time. It's an
- engineering maxim that "There is always time to do it over,
- but never time to do it right the first time."
