Building for longevity

To avoid future problems resulting from issues when making modifications to a system in production as a result of changes in user requirements, as well as bugs which get exposed because of inherent bad code in a code base and accumulated technical debt, you need to have the mindset of developing with the future in mind and embracing changes.

Use flexible patterns and always employ good object-oriented development and design principles when writing code. The requirements of most software projects change over their life cycles. It is wrong to assume that a component or part might not change, so try and put a mechanism in place to allow the application to be graceful and accept future changes.
