posted Sep 19, 2011, 2:17 PM by Eddie Woo
Old system, meet new system! Now that you have spent the time to design your new information system, and ensured that it will meet the needs of the people who will be using it... now you have to decide how it's going to replace the pre-existing system. Today we'll look at the different ways there are to convert from one system to another.
  1. Construct and fill out the following table on the basis of our class discussion. In the "Method" column, describe the conversion method verbally and visually.

    Method
    Advantages
    Disadvantages
    Direct
       
    Parallel
       
    Phased
       
    Pilot
       

  2. Using the supplied worksheet, identify and justify a suitable method of converting the old system to the new system for each scenario. Use a combination of methods where appropriate.

  3. Provide a detailed description of the conversion process that you would use for Canteen 2012, and justify your selection of method.
