Parallel Adoption - Control System

Control System

• Automatic catch ups: Catch ups that are being transferred by an automated system, created in the preparing the organization phase. This system automically transfers the data or information to the new system when the conversion goes from the old leading system to the new leading system. The benefit of an automated system is that it is fast and accurate. The disadvantage is that is takes time to produce a transfer system in an earlier stage.
• Catch ups by hand: When the actual conversion entails only a small amount of time, or the complexity of information that should be transferred to the new system is small, an organization can choose to transfer the catch ups manually. The advantage of this procedure is that there is no need for a system (software program) to transfer the information and the possible problems that come with such kind of a transfer-program. The trade-off is accuracy and time. It takes a considerable amount of extra time, to transfer the catch ups manually and it is more vulnerable for small human errors (Rooijmans, 2003). Moreover, the additional investment in labour hours is high already; a manual catch up system places even more pressure on the personnel.
