What is the 40 20 40 rule in software engineering?

The 40-20-40 rule in software engineering is a time allocation guideline for projects, suggesting 40% for planning/design, 20% for coding, and 40% for testing/deployment, emphasizing that significant effort goes into upfront design and final quality assurance, not just writing code. This contrasts with the financial "Rule of 40" for SaaS companies (growth % + profitability %), but the project-based rule highlights the importance of robust processes for successful software delivery, ensuring thorough analysis and rigorous testing, as coding itself is a smaller portion of the overall work.
