You have completed the system design for the customer relationship support system at Mentari Hijau Berhad. Your team are now ready to finish the software development and begin installation, testing and evaluation of the new system. The system manager has e- mailed you a memo that contains some important instructions. The memo is as below: MEMORANDUM Date : 23 November 2019 From : System Manager To Project Manager [IS Development Team) With reference to the presentation to the Board of Directors during the Board's meeting on 20 November 2019, on behalf of the board, I grant the permission to continue to the IMPLEMENTATION phase for the Customer Relationship Support System at Mentari Hijau Berhad. The following are some important information that you should take into consideration in implementing the system: 1. In testing the system, be sure you put lots of errors into the test data. Users are bound to make mistakes, and we need to design built-in safeguards that will identify the mistakes, and either fix them automatically, or alert the user on the problem. 2. In planning the training activities, please take note that Mentari Hyou Berhad staff who are involved in customer relationship management mostly work remotely from outside the office most of their time. Please plan for suitable training activities that suit the nature of working environment for the staff. 3. Three months after the system changeover, please perform a post- implementation evaluation.
