1 Presented By: Amith Kumar Vangala Success and Failure factors in Software Reuse

2 What is Software Reuse?  Software Reuse is building up or updating of software using the existing software components.

3 Why Reuse Software? Productivity Productivity Quality Quality reliability reliability cost cost Implementation time Implementation time Future projects development time Future projects development time

4 Types of Reuse  Horizontal reuse  Vertical reuse- Domain Engineering, Application Engineering Application Engineering

5 Why Software Reuse failed over the years ?  Administrative obstacle  Organizational obstacle  Political obstacle  Psychological obstacle

6 Reuse Costs-Investment:  Process  Necessary Tools  People-training

7 Software Reuse Decision Sequence:  Reuse Potential  Reuse Capability  Reuse Implementation

8 Reuse Potential:  Identifying functions  Identifying the number of reuses

9 Reuse Capability:  Change non-reuse specific processes  Add reuse-specific processes  Address human factors  Set up a repository

10 Reuse implementation:  Change non-reuse specific processes:  Add reuse-specific Processes:  Address human factors:  Set up a repository:

11 Conclusion:  Commitment  Non-awareness  Blind Belief  Planning
