Localized change management in two cases : supply base cost escalation and obsolescence management
… is forecasted. The goal in this case is a quick, top-down method for forecasting headwind to replace a time-intensive, bottom-up method. The second case is a change in the evaluation method of obsolescence risk mitigation options. This effort is intended to improve the evaluation of these options …
