System Re-Engineering

The process of software re-engineering is to improve the maintainability of a software system. Software re-engineering is a cost-effective option for software system evolution. Reverse engineering and program re-structuring which may be involved in the software re-engineering process.

• Source code translation
• Reverse engineering
• Program structure improvement
• Program modularization
• Data re-engineering

Re-engineering a software system has two key advantages over more radical approaches to system evolution:

1. Reduced risk

There is a high risk in re-developing software that is essential for an organisation. Errors may be made in the system specification, there may be development problems, etc

2. Reduced cost

The cost of re-engineering is significantly less than the costs of developing new software.
