Question:
From the introductory conversation Chip and Anna shared, which elements mentioned might suggest the use of CASE tools?
Answer:
CASE tools are used for increasing analyst productivity, Improving analyst-user communication and integrating life cycle activities.
CASE tools would be used to help Chip and Anna communicate with each other and share portions of the design that they have completed.
Because there are many users for the Computer System, CASE tools will help to facilitate communication among the users and analyst and document the information that they have received as a result of interviews, document analysis, and questionnaires.
Features of Case Tools:
Increasing analyst productivity, Improving analyst-user communication and integrating ly of 53 companies, found that 39 (73.5%) had never used CASE. Of the 14 companies who had tried CASE, five had subsequently abandoned use of the tools. People within these fourteen companies believed that use of CASE tools improved documentation quality, improved analysis, and resulted in systems that were easier to test and maintain. However, they also found use of CASE tools difficult and time consuming. In another cross organization survey, found that only 24% of companies were using CASE tools. In a follow-up survey of thirteen managers who had been using CASE tools two years earlier, reported that continued CASE use could only be verified for four managers. The reasons for abandonment included cost, lack of measurable turns, and unrealistic expectations. Looking within organizations that used CASE tools it was found that large numbers of their systems developers were not using CASE tools.ife cycle activities.
The term Computer-Aided Software Engineering (CASE) encompasses many different products with different functionalities. In the International Workshop on Computer-Aided
