Discuss the four conversion strategies.
What will be an ideal response?
Student responses will vary, but should be drawn from the following information from the text.??The final implementation activity is to change from the old system to the new system. This change can take place using one or more of the following conversion strategies: direct, parallel, phased, or pilot.• With direct conversion, the user stops using the old system and begins using the new system on a certain date. The advantage of this strategy is that it requires no transition costs and is a quick implementation technique. The disadvantage is that it is extremely risky and can disrupt
operations seriously if the new system does not work correctly the first time. • Parallel conversion consists of running the old system alongside the new system for a specified time. Results from both systems are compared. The advantage of this strategy is that you can fix any problems in the new system before you terminate the old system. The disadvantage is that it is costly to operate two systems at the same time.
• In a phased conversion, each location converts at a separate time. For example, an accounting system might convert its accounts receivable, accounts payable, general ledger, and payroll sites in separate phases. Each site can use a direct or parallel conversion. Larger systems with multiple sites may use a phased conversion.
• With a pilot conversion, only one location in the organization uses the new system - so that it can be tested. After the pilot site approves the new system, other sites convert using one of the other conversion strategies.
