Investigating Schedule Slippage, James V. Monaco, Edward D. White Apr 2005

Investigating Schedule Slippage, James V. Monaco, Edward D. White

Faculty Publications

Past research shows that schedule slippage within the acquisition community often adversely affects the cost and performance characteristics within a program. To minimize the risk of underestimating schedule growth, a program manager needs a reliable initial schedule estimate. Statistical models can provide such estimates; however, they require accurate historical data and predictive drivers. Many archival studies have investigated potential drivers of schedule growth. In this article, we review several of those studies that investigated schedule slippage and highlight common potential drivers of schedule growth, ending with a list of variables for estimators to consider for incorporating into future predictive models.

Using Depot Inventory Position To Determine Transportation Mode Of Retrograde Reparable Assets, Edward C. Snow Jr. Mar 2005

Using Depot Inventory Position To Determine Transportation Mode Of Retrograde Reparable Assets, Edward C. Snow Jr.

Theses and Dissertations

Air Force logistics policies direct the "expedited evacuation of repairables to the source of repair", in an effort to allow smaller inventories. Transportation Mode selection is based only on the asset itself. This focus works well when shipping assets out from the depot to a base. When a base ships an asset back to the depot however, the priority of the asset may not be the best way to select the transportation mode. The quantity of the assets at the depot may indicate that fast transportation is unnecessary. The depot may already have enough serviceable assets to meet demand or …
