Success and Failure factors in Software Reuse Presented

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

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

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

Types of Reuse Ø Horizontal reuse Ø Vertical reuse- Domain Engineering, Application Engineering

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

Reuse Costs-Investment: Ø Process Ø Necessary Tools Ø People-training

Software Reuse Decision Sequence: Ø Reuse Potential Ø Reuse Capability Ø Reuse Implementation

Reuse Potential: Ø Identifying functions Ø Identifying the number of reuses

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

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

Conclusion: Ø Commitment Ø Non-awareness Ø Blind Belief Ø Planning
