Quick-fix Model - Software Engineering

Software Maintenance is modifying a software system after delivery to correct faults, add new features, and remove obsolete functions. The maintenance process varies considerably depending on the type of software being maintained. The most expensive part of the software life cycle is the software maintenance process. There are some models for software system maintenance, and the quick-fix model is one of them. 

What is Quick-fix Model?

Quick-fix model is an ad hoc approach to maintaining software. It is a fire-fighting approach waiting for the problem to occur and then trying to fix it as quickly as possible.

1. The main objective of this model is to identify the issue and then fix it as soon as possible.
2. In this model, changes are made at the code level as early as possible without accepting future issues.
3. This model is an approach to modifying the software code without little consideration of its impact on the overall structure of the software system.

As a result of this model, the structure of the software degrades rapidly

Objectives of Quick-fix Model:

1. Resolving Serious Issues: The quick-fix model might try to quickly find and address serious problems or defects that are seriously impairing system functionality or the user experience.
2. Reducing Unavailable Time: The quick-fix model aims to minimize downtime by offering prompt solutions to restart a system that is experiencing downtime as a result of a major issue.
3. Keeping Data Safe: When there is a chance of data loss or corruption, the quick-fix model seeks to put temporary fixes in place so that problems can be avoided or resolved.
4. Reducing High-Impact Problems: One of the main objectives of the quick-fix approach is to identify and mitigate issues that have a significant impact on revenue, user satisfaction or other vital business factors.

Advantages of Quick-fix Model:

1. The main advantage is that it performs its work at low cost and very quickly.
2. Sometimes, users don't wait for a long time. Rather, they require the modified software to be delivered to them in the least possible time. As a result, the software maintenance team needs to use a quick-fix model to avoid the time-consuming process of the Software maintenance life cycle.
3. This model is also advantageous in situations where the software system is to be maintained with certain deadlines and limited resources.

Disadvantages of Quick-fix Model:

1. This model is not suitable for large project system and work only for small programming exercises.
2. The aspect of designing and development in a structured way is missing.
3. This model is not suitable to fix errors for a longer period, as the structure of the software system degrade rapidly.

Conclusion:

In software engineering, the quick-fix model is a practical and quick-fix method to deal with urgent needs, pressing problems or obstacles that arise right away. This methodology has benefits as well as drawbacks, even though it can quickly address urgent issues. In software engineering, this paradigm is essential because it enables teams to react quickly to pressing issues and preserve system stability.
