Conversion Strategies
(^) Direct conversion o (^) The new system instantly replaces the old (^) Parallel conversion o (^) For a time both old and new systems are used. The old is abandoned when the new is proven fully capable.
(^) Pilot conversion o (^) One or more locations are converted to work out bugs before extending to other locations (^) Phased conversion o (^) Locations are converted in sets
(^) Pilot conversion o (^) One or more locations are converted to work out bugs before extending to other locations (^) Phased conversion o (^) Locations are converted in sets (^) Simultaneous conversion o (^) All locations are converted at the same time
Risk ◦ (^) Seriousness of consequences of remaining bugs Cost ◦ (^) Parallel requires paying for two systems for a period of time ◦ (^) Simultaneous requires more staff to support all locations Time ◦ (^) Parallel, phased, and modular require more time
To minimize risk… ◦ (^) Parallel conversion style ◦ (^) Pilot conversion location ◦ (^) Conversion by modules Riskiest conversion strategy: ◦ (^) Direct conversion style ◦ (^) Simultaneous conversion location ◦ (^) Conversion of whole system
To minimize time… ◦ (^) Direct conversion style ◦ (^) Simultaneous conversion location ◦ (^) Conversion of whole system Longest time conversion strategy: ◦ (^) Parallel conversion style ◦ (^) Phased conversion location ◦ (^) Conversion of modules
