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

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.
