Prioritizing Technical Depth: Balancing Adaptation and Complexity

🔑Lehman's laws of revolution capture the challenges of continuous change and increasing complexity in software development.

🧩Successful products are never done; they require continuous adaptation and evolution to remain useful over time.

🔄The law of increasing complexity states that system complexity will naturally increase unless actively reduced.

🔄Ignoring complexity leads to a vicious cycle of longer cycle times, unpredictability, staff turnover, and external quality issues.

📊Quantifying technical depth through static code analysis provides insights but lacks actionability.

What are Lehman's laws of revolution?

—Lehman's laws of revolution capture the challenges of continuous change and increasing complexity in software development. They highlight the need for continuous adaptation and the risk of spiraling complexity.

Why do successful products require continuous adaptation?

—Successful products are never done. To remain useful over time, they need to evolve, add new features, and adapt to changing user needs and market demands.

What is the law of increasing complexity?

—The law of increasing complexity states that system complexity will naturally increase unless actively reduced. Ignoring complexity leads to longer cycle times, unpredictability, staff turnover, and external quality issues.

Why is quantifying technical depth through static code analysis not enough?

—While static code analysis provides insights into technical debt, it lacks actionability. Quantifying technical depth requires looking beyond code and considering factors like team dynamics and external quality.

What are the consequences of ignoring complexity?

—Ignoring complexity leads to a vicious cycle of longer cycle times, unpredictability, staff turnover, and external quality issues. It becomes harder to respond to change, impacting product execution and end-user experience.
