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)

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.
