Question

1. the ______ approach to systems implementation is used only in cases in which the cost of failure or of interrupted operation is great. phased direct pilot parallel 28. selecting the best system is the first step of the systems design phase of the systems life cycle. true false 29. these tools, also called computer - aided software engineering (case) tools, are used in system analysis to evaluate alternative hardware and software solutions. project management tools automated design tools spreadsheets report generators

Explanation:

• For question 27: The parallel approach to systems implementation runs the old and new systems simultaneously. It's used when the cost of failure or interrupted operation is high as it provides a fallback with the old system while the new one is tested in real - time.
• For question 28: The first step in the systems design phase of the systems life cycle is defining the problem and requirements, not selecting the best system.
• For question 29: Automated design tools, also known as CASE tools, are used in system analysis to evaluate alternative hardware and software solutions.

Answer:

1. parallel
2. False
3. Automated design tools
