Maintenance Phase

Maintenance phase involves performing one or moreof the following activities:

1. Corrective maintenance:

Fixing errors not detected during the development phase

2. Adaptive maintenance: Improving implemented system e.g. performance

Enhancing functionalities e.g. new requirements

Porting software to new environment (as needed)

Maintenance phase consumes far more effort than thedevelopment phases (40:60)
