Risk affects both the shipyard and ship's force because the completion of the overhaul could be affected by late authorized work resulting in the ship not being able to meet her commitments. As Philadelphia Naval Shipyard (PNSY) is an industry leader in zone or Group Technology execution methods, it is particularly disruptive to work flow to return to geographic areas and perform work in an area out of phase or even worse-in an area where similar work is already complete. In the past the tools that were most often employed to build an effective work package, yet still remain within the budget, were personal experience, historical data and trends, and the necessary deletions of less critical work in favor of accomplishing essential repairs. The shipyard's success at making these determinations was held hostage by purely subjective opinions of the particular group of advance planners that attended the Work Definition Conference (WDC) and executed most of the advanced planning, without consideration of established overhaul objectives. With the innovation of Zone Technology, it was clear that a consistent and effective risk assessment method must be developed to determine the probability of equipment failure during the testing phase of the overhaul and the impact on cost and schedule to the overhaul. The USS KIDD (DD-963) scheduled availability in 1989 proved to be the ideal opportunity to develop and execute a formal risk assessment and management program. The USS CONSTELLATION (CV-64) SLEP availability in 1990 afforded the opportunity to refine and expand the risk assessment methodology. / NOTE:Conference paper. |
