Welcome to this video training session. In the session, you will learn about changeover methods. As a reminder, you can pause the session at any time, or go back to review an earlier section. Now let’s get started.
· System changeover is the process of putting the new information system online and retiring the old system. · Changeover can be rapid or slow, depending on the method. · The four changeover methods are direct cutover, parallel operation, pilot operation, and phased operation.

Let’s look at each method, and consider some pros and cons.
· Direct cutover is similar to throwing a switch that instantly changes over from the old system to the new. This method is fast, but the most risky. · Parallel operation requires that both systems run simultaneously for a specified period, which is the slowest method, but the safest. · Pilot operation changeover involves implementing the complete new system at a selected location. This is like direct cutover, but only at a single location, so the risk is limited. · Phased operation changeover allows you to implement the new system in stages, or modules. This is like parallel operation, one phase at a time. The risk only involves one phase at a time.

Now let’s take three specific examples, and see which method we might choose:
· Mission-critical corporate accounting system In this example, the primary goal is to minimize the risk. All other issues are secondary. This would be a good situation for parallel operation, which is slower, but involves the least risk.
· Franchise operation with 500 locations Here, if we choose pilot operation, we can evaluate the entire system, but at a single location. If all goes well, we can implement at other locations, or make necessary changes.
· Records archive system for five-year old data In this example, we can tolerate some risk. Because the old data is archived and not mission-critical. We can probably reduce costs and speed up the process by using direct cutover.
