CASE tools can lead to significant improvements in software quality and productivity.

•CASE Tools support process activities such as requirements engineering, design, program development and testing.•CASE tools include:• compilers, debuggers, build tools,• integrated development environments• design editors• data dictionaries• tools that support the visualization / comprehension of

existing code• ...

|Computer-Aided Software Engineering 4A Classification of CASE tools

• Tools support individual process tasks (e.g. compiling a program)• Workbenches support process phases (e.g. requirements

specification or design) • Environments support a substantial part of the software process.

“Computer-Aided Software Engineering

The possibilities for improvements of the software process by CASE tools are limited.

11

Limiting factors:

1.Software engineering is a design activity based on creative thought.

2.Software engineering is a team activity and quite a lot of time is spend on interacting with other team members, which is (still) not well-supported by current CASE tools.(However, recent tools and plug-ins start to offer corresponding support.)
