IS Maintenance Practices

System maintenance refers to making changes or improvements to a system to make it better. This applies to all types of systems, whether they are developed in-house, purchased as a package, or customized for a specific organization. Maintenance is important because systems are not static and need to be updated or fixed over time.

There are four types of system maintenance practices:

1. Corrective maintenance: This involves finding and fixing problems or errors in the system.

2. Adaptive maintenance: This type of maintenance adds new features or capabilities to the system based on user or management requests.

3. Perfective maintenance: This focuses on making the system more efficient and user-friendly without changing its capabilities.

4. Preventive maintenance: This aims to prevent problems or vulnerabilities in the system, such as hacking or adding security features.

When users want to request a system maintenance practice, they usually fill out a form with their name, the date, and the reason for the change. It's important to also mention the expected benefits and prioritize the request. The IT department reviews these requests and decides which ones to prioritize based on their judgment and the information provided.

System maintenance costs can vary over time, starting high at the beginning, decreasing as problems are fixed, and then increasing again as new features are added, or the system becomes outdated.
