Amira is a new systems analyst, hired by Rizqa IT Services. She was just graduated from Universiti Utara Malaysia. Mr. Nuqman, the senior systems analyst assigns Amira to handle the testing and maintenance for a new inventory management system that is currently being developed by Rizqa IT Services. Amira is very upset with the tasks that she receives from Mr. Nuqman. She has no experience and does not know where to start. Knowing that Amira is struggling with the task given, Mr. Nuqman gives the following notes: 

Hi Amira 

Don't worry. You can did this. I would suggest a few recommendations for you to follow in performing the testing and maintaining the new inventory management system. See if these will work: 

1. You must perform all appropriate testing for the new system. Focus on the programme that produces incorrect results. Hence, you need to show a complete test plan on the detailed procedures on what kind of testing that you want to perform. Make sure the tests could spot logic errors and do not forget to conduct an independent analysis during the testing. 

2. Once you conduct your testing plan, keep this in mind. No system is 100% error free. There is an occasion when errors go undetected until the system becomes operational. Some errors can be corrected later.

 3. When you are about to install the new system, identify the correct environment to support the installation process. 

4. As for the system changeover, keep in mind that this new inventory management system is critical to the client's company. As a result, they cannot bear any risks. However, this new system is not compatible with the old one that is currently used by the client. Hence, the operating environment could not support both systems. In addition, this new system cannot be separated into logical modules. 

Sincerely, Nuqman
