Software Maintenance and Development

Software Maintenance Practices

• Most departments are practicing corrective maintenance, which is insufficient on its own.
• Adaptive maintenance is also necessary to allow for rapid growth, as per the law of continuing change.
• Developing new software is important, but it's equally crucial to enhance existing software to stay competitive.

Importance of New Releases

• New releases are essential to keep customers interested in products.
• This requires engineers to practice perfective maintenance.

Key Principles of Maintenance

• Always repair problems as soon as they are identified.
• Be aware of the law of increasing complexity, which can make software difficult to maintain if it becomes too complex.
• Engineers should know when to update and when to write a new program.

Code Quality

• Unstructured code is no longer tolerated, as it causes confusion and makes further updates more difficult.
• Well-structured code is essential for efficient maintenance.

Strongest Software Maintenance Practice

• Preventive maintenance is the strongest software maintenance practice.
