Codebase Decisions, Part 2: Best Practices

In part one of this two-part blog series, we looked at two approaches to codebase decisions: working with existing code patterns and refactoring for improvement. Next, we’ll review 10 best practices on this same topic.

1. Consider the Urgency

When deciding between working with existing code patterns and refactoring, consider the urgency of the situation. For critical issues that significantly impact functionality or user experience, quick fixes to existing code may be the best solution. For less critical issues, it’s an opportunity to consider the long-term benefits of refactoring.

2. Be Aware of Technical Debt

Keep an eye on technical debt. Be aware of the signs of accumulating technical debt, such as tangled code, complex logic, and workarounds. Regularly assess the codebase’s health to determine when refactoring is necessary to prevent future complications.

3. Weigh the Impact on Development Velocity

Balance the potential impact of each approach on development velocity. While maintaining the status quo (i.e. working with existing code patterns) may offer quick solutions, it could also slow down development over time due to increased technical debt. Refactoring often requires an initial time investment, but can result in smoother, more efficient development in the long run.

4. Align with Business Objectives

Align your decisions with your business objectives. Consider the goals of your project and the desired outcomes. A business focused on rapid feature delivery might prioritize maintaining the status quo, while a business focused on long-term stability might lean towards refactoring.

5. Encourage Collaboration

Prioritize collaboration within your development team. Involve team members in the decision-making process, ensuring that everyone understands the implications of each approach. Collaborative decisions foster a shared commitment to the chosen path.

6. Create a Technical Strategy

Develop a technical strategy that outlines when each approach is suitable. Define criteria for when quick fixes are appropriate and when refactoring should be considered. Having a clear strategy streamlines decision-making and prevents ad-hoc decision making.

7. Evaluate the Long-Term Vision

Always consider the long-term vision of your project. Think beyond immediate needs and assess how your decisions may impact the project’s growth, adaptability, and sustainability. Refactoring might slow down progress momentarily but sets the stage for a more resilient codebase.

8. Measure Impact and Learn

After implementing, measure the impact. Did a quick fix successfully address the issue, or did it introduce unforeseen complications? Did refactoring result in improved code quality and development efficiency? Whatever the outcomes, learn from them and refine your decision-making process.

9. Adapt and Evolve

Software development is fluid, and circumstances change. Be ready to adapt your approach based on new information, emerging challenges, or shifting project priorities. Flexibility is a key trait of successful developers.

10. Strive for Balance

Above all, strive for balance. Balancing short-term goals with long-term code quality is a continuous effort. Consider the trade-offs, assess the situation holistically, and make decisions that position your project for success today and tomorrow.
