Would a systems analyst be better off in a position where he or she works with an IDE, or where generic CASE tools are used? Explain your answer.
What will be an ideal response?
Answers will vary. As the textbook points out, in a specific software environment, an integrated development tool is highly effective because it is an integral part of the vendor’s software package. Each IDE, however, is different and requires a learning curve and skills that might or might not be readily transferable. In contrast, non-specific CASE tools such as Visible Analyst or System Architect can be used in any development environment. Given the dynamic changes in IT, a systems analyst should seek to learn as many development and CASE tools as possible.
