6. MAINTENANCE & CONTINUOUS IMPROVEMENT
After your software is deployed, the work doesn’t stop. Maintenance and continuous improvement are essential to keep your application running smoothly and to ensure it evolves to meet user needs. This phase involves not only fixing bugs and releasing updates but also maintaining clear documentation, ensuring scalability, and leveraging feedback loops to guide future iterations. A well-maintained software product is reliable, scalable, and adaptable, making it crucial for long-term success.
"Everything in software changes. The requirements change. The [design, business, technology and team changes.] The problem isn't change, because change is going to happen; the problem, rather, is our inability to cope with change. "
- Kent Beck
Feedback Loops & Iteration are key to improving your software over time. When you release your product, you’ll gather feedback from users about what they like, what they find challenging, and what they wish was different. This feedback is invaluable for making meaningful improvements.
Software is never done!
Iteration means making gradual changes based on this feedback. Instead of trying to get everything perfect in one go, you release your software, gather user input, and then make updates. This approach allows you to continuously refine and enhance your product.
tips & tricks
Here are a few tips to handle client requests wisely:
- Evaluate Broader Value. Check if the feature benefits other clients and fits within the product roadmap.
Definition and Scope. Ensure the request is clear and appealing to a wider audience.
Consider Alternatives. Look for existing features or solutions that meet the client’s needs without customization.
Avoid Client-Specific Solutions. Prioritize flexible solutions over hardcoding to prevent future issues and technical debt.
Think Long-Term. Balance immediate client needs with future scalability and maintainability.
Technical debt refers to the shortcuts or less-than-ideal solutions that are sometimes used to meet tight deadlines. While these shortcuts can speed up development in the short term, they accumulate "debt" that must be "paid off" later to avoid larger problems. This is similar to skipping regular car maintenance—eventually, the issues pile up, leading to more significant costs and complications. It can also negatively impact team morale and motivation. When the codebase becomes increasingly complex and difficult to manage, it can lead to frustration and decreased job satisfaction among developers. This, in turn, may result in lower code quality and reduced productivity.

In fast-paced development environments, some technical debt is inevitable. However, it’s important to manage it effectively. It's recommended to allocate 10% to 30% of the team's efforts to addressing technical debt, once you have launched your first product. Tools like SonarQube can help measure and track this debt, while regular code reviews can flag areas that need attention. Prioritize addressing high-impact debt first and incorporate debt management into the overall development process. By doing so, you can keep the codebase healthy and ensure continuous improvement over time.
In Summary:
-
Gather and Analyze Feedback. Collect user feedback on your software to understand their needs and challenges, and use this information to make informed improvements.
- Iterate Gradually. Implement updates in phases based on feedback, making incremental changes rather than trying to perfect everything at once.
- Evaluate and Prioritize Client Requests. Assess whether client requests offer broader value, and avoid custom solutions that create technical debt or complicate future updates.
- Manage Technical Debt. Allocate a portion of your team’s efforts to address technical debt regularly, using tools and practices to keep your codebase healthy and maintainable.
