Question

1. during which phase of the systems life cycle are users trained to use the new system?

○ preliminary investigation
○ systems implementation
○ systems development
○ systems maintenance

1. in the preliminary investigation phase of the systems life cycle, which one of the following tasks would not be included?

○ briefly defining the problem
○ suggesting alternative solutions
○ gathering the data
○ preparing a short report

1. in the design phase of the systems life cycle, alternative systems are analyzed for economic, physical and operational feasibility.

○ true
○ false

Explanation:

• For question 24: In the systems life - cycle, users are trained to use the new system during the systems implementation phase. This is when the new system is put into operation and users need to be familiarized with it.
• For question 25: In the preliminary investigation phase, tasks include briefly defining the problem, gathering data, and preparing a short report. Suggesting alternative solutions is typically done in later phases like the design phase, not in the preliminary investigation phase.
• For question 26: In the design phase of the systems life - cycle, alternative systems are indeed analyzed for economic, physical, and operational feasibility.

Answer:

1. Systems implementation
2. Suggesting alternative solutions
3. True
