Parallel Adoption - Conversion Scenario

Conversion Scenario

The conversion scenario thus consists of a blueprint for the organizational change in all aspects. However, there are two topics that did not yet get the attention they deserve in the parallel adoption scope.

• Workaround strategy / Rollback plan: Being distinct from the other adoption scenarios, also integrated in the conversion scenario is the workaround or contingency strategy with a rollback plan. The workaround strategy is defined in a broader scope in another entry, but in this context it indicates as defined in the above table: A backup plan; strategy taken on, in the conversion scenario to prevent errors in the conversion process and attempt to work around them, so that the implementation can still be successful. (Microsoft, 2004). The rollback plan, as being one possible workaround strategy, is initiated if something goes wrong in the conversion phase. Since the two systems run simultaneously, in a parallel adoption, the rollback plan indicates that the database or other system that handles the transactions should be fully retraceable in the legacy system (Microsoft, 2004). In fact the parallel adoption provides per definition this rollback plan due to its nature of a leading system and a (non-leading) backup system.
• Criteria indicators: Since the conversion scenario is a blueprint of executing the transfer of the two systems, is also entails quantifiable criteria. The redefined IT and organizational requirements are being transferred into measurable components. When the criteria are not being met in the test conversion, the workaround strategy should be deployed.
