How to achieve high Maintainability

Designing a highly maintainable system requires a proactive approach during the development process. Here are some strategies to achieve and improve maintainability in system design: –

Follow Design Patterns:

Design patterns, such as Model-View-Controller and SOLID principles, promote modularity, and flexibility. Following these patterns enhances overall architecture while making it easier to maintain.

Code Consistency:

Well-written, readable code with meaningful variables, comments, and documentation makes maintenance tasks even smoother. So, as much as possible while writing code or documentation make it simple in design and implementation.

Conduct Code Reviews:

Code reviews by peers, and maintainers can help in identifying potential issues early on, while making sure that code adheres to maintainability standards and preferred code style or not.

Test-Driven Development (TDD):

Adopting TDD ensures that test cases are written before the code implementation, helping developers understand the codebase easily while troubleshooting an issue.

Documentation:

Good documentation reduces the learning curve for new Devs and helps the existing team understand it better during maintenance. Maintain thorough documentation of the system’s architecture, APIs, modules, and dependencies.

Plan for Change:

Design the system in such a way, that makes it easier to add new features and adapt to evolving requirements of daily enhancements.

Automate Testing and Deployment:

Automating testing and deployment processes reduces the chance of human error helps maintain the stability of the system during updates and also saves time and effort of team members, allowing them to work on important issues.

Maintainability determines how easy and profitable it will be to maintain, update, and do upgrades in that software system. In this composition, we will understand the concept of maintainability in System Design, see how we can measure it, and bandy some stylish practices to achieve high maintainability as well.
