In a growing project, developers should prioritize delivering business value over striving for perfection in their coding practices. Tools and technologies are merely means to achieve end goals, not the goals themselves. It’s essential to question the necessity and timing of implementing features or tools based on their immediate value to the project. Developers should also focus on understanding the business aspects of the project, anticipate risks, and provide scalable solutions without getting bogged down by the desire to use perfect code or architecture from the start. Collecting feedback and adapting based on it is crucial, as is maintaining a mindset geared towards effective, value-driven outcomes rather than perfect solutions.
