CMM Overview ........................................................................................................ 172 This course is a continuation of the first course on Software Engineering. In order to set the context of our discussion, let us first look at some of the definitions of software engineering.

Software Engineering is the set of processes and tools to develop software. Software Engineering is the combination of all the tools, techniques, and processes that used in software production. Therefore Software Engineering encompasses all those things that are used in software production like:

•  Programming Language
•  Programming Language Design
•  Software Design Techniques
•  Tools
•  Testing
•  Maintenance
•  Development etc.

So all those thing that are related to software are also related to software engineering.

Some of you might have thought that how programming language design could be related to software engineering. If you look more closely at the software engineering definitions described above then you will definitely see that software engineering is related to all those things that are helpful in software development. So is the case with programming language design. Programming language design is one of the major successes in last fifty years. The design of Ada language was considered as the considerable effort in software engineering.

These days object-oriented programming is widely being used. If programming languages will not support object-orientation then it will be very difficult to implement objectoriented design using object-oriented principles. All these efforts made the basis of software engineering.

Well-Engineered Software

Let’s talk something about what is well-engineered software. Well-engineered software is one that has the following characteristics.

•  It is reliable
•  It has good user-interface
•  It has acceptable performance
•  It is of good quality
•  It is cost-effective
