• 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
• Quality
• reliability
• cost
• Implementation time
• Future projects development time

4
Types of Reuse

• Horizontal reuse
• Vertical reuse- Domain 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
