Software engineering layers

WHAT IS SOFTWARE ENGINEERING?
According to IEEE software engineering is defined as the application of the systematic, discipline, quantifiable approach to development of an operation and maintenance of software.

3. QUALITY Engineering approaches rest on an organizational customer quality requirements (efficiency, reliability, etc.), developer quality requirements (maintainability, reusability, etc.), users (usability, efficiency, etc.), and etc. Some quality requirements are difficult to specify in an unambiguous way. Software specifications are usually incomplete. The bedrock that supports software engineering is a quality focus layer. A product should meet its specification.

4. PROCESS The foundation for software engineering is the ̳process layer. The process layer allows the development of software on time. The work products are produced, milestones are established, quality is ensured, and changes are properly managed. Software engineering process is the glue that holds the technology together and enables rational and timely development of computer software. It forms the base for management control of software project

5. METHODS The method layer provides technical knowledge for developing software. This layer covers a broad array of tasks that include requirements analysis, design, coding, testing, and maintenance phase of the software development. Software engineering methods provides the technical how- to‘s for building software

6. TOOLS The tools layer provides computerized or semi-computerized support for the process and the method layer. Sometimes tools are integrated in such a way that other tools can use information created by one tool. This multi-usage is commonly referred to as Computer-Aided Software Engineering (CASE). CASE combines software, hardware, and software engineering database to create software engineering analogous to Computer-Aided Design (CAD) for hardware. CASE helps in application development including analysis, design, code generation, and debugging and testing.
