Chapter 1 Problems and Exercises 1. By following the system analysis and design methodologies you will be able to answer questions for the end user because you are going to build the system and design it to the end user. For example you build a system for tracking inventory and train the managers how to use it so they know what inventory is available. You don’t want to build the system in a quick and easy format because then it might not perform up the tasks that are required of it. By using the engineering approach I will be using the input from the users of the system to build a proper system that will benefit the current and future users. Also it will allow me to use current tools available to make sure the programs are functioning as required.

8. Prototyping during the SDLC life cycle may be incorporated in any of the 2nd and 3rd phases. You would create the prototype during the 2nd phase and then revamp it during the 3rd phase, and in the final phase it would be implemented. I feel that these two styles do not really mix that well but if necessary you could use prototyping during the SDLC process.

Q3. I would say all 8 are still important but the top 2 that I would use to make the final decision is Vendor support and Viability of Vendor Vendor support is just what it says, the support that the vendor will supply with the building and implementing of the software. And Viability of Vendor is how long the vendor has been around and how long it seems that it will stay in practice.

Q4. One such remark to justify the recommendation is that all systems are updated at the same time, for example if a individual purchases an item it would be immediately removed from the warehouse, invoiced from accounting, and adjusted on the accounts receivable account all at the same time. This reduces the need to
