A Layered Technology

Divided into 4 layers:-

1. A quality Process :-     

•   Any engineering approach must rest on an quality.
• The "Bed Rock" that supports software Engineering is Quality Focus.

2. Process :-

• Foundation for SE is the Process Layer
• SE process is the GLUE that holds all the technology layers together and enables the timely development of computer software.
• It forms the base for management control of software project.

3. Methods :-

• SE methods provide the "Technical Questions" for building Software.
• Methods contain a broad array of tasks that include communication requirement analysis, design modeling, program construction testing and support.

4. Tools :-

• SE tools provide automated or semi-automated support for the "Process" and the "Methods".
• Tools are integrated so that information created by one tool can be used by another.
