Software Development Life Cycle (SDLC).

SDLC,aslo known as a Software Development Process, is a structrue imposed on the development of a software product.

Software developemment activites.
1.Planning
  - An important task in creating a software program is extracting the requirements or requirements analysis.

2.Implementation , testing and documenting.
  - Implemention is the part of the process where softwre engineers actually program the codes for the project.
  - Software testing is an integral and improtant phase of the software development process. This part of the process ensures that defects are recognized as soon as possible.
  - Documenting the internal design of software for the purpose of future maintance and enhancement is done throughout development.

3.Deployment and maintenance.

Software development models.
Waterfall model
1. Requiremnts specificification ( Requirements analysis)
2. Software design.
3. Implementation and Integration.
4. Testing (or Validation)
5. Deployment ( or Installation)
6. Maintenance.

Process improvement models.
CMMI ( Capability Maturity Model Integration )
- Is a process improvement approach that provides organization with the essential elements for effective process improvement.
