one-three-one-rule

The 1-3-1 framework is a structured format for technical proposals that defines one clear problem statement, three distinct options with trade-off analysis, and one concrete recommendation with an implementation plan.

To write a technical proposal for system architecture trade-offs, frame a clear problem statement, compare three viable approaches by evaluating their pros and cons, and conclude with a single recommendation supported by an actionable implementation plan.

Yes, you can apply this structured decision-making format to scenarios involving multiple viable approaches, including database selection, architecture decisions, and refactoring strategies by generating a comprehensive trade-off analysis document.

The best way to compare multiple viable approaches is using a structured trade-off analysis that contrasts three distinct options against a single problem statement to produce a clear recommendation with an implementation plan.

You should not use the 1-3-1 format for technical proposals when your problem lacks multiple viable approaches or when the scenario does not require detailed trade-off analysis, option comparison, and a recommendation with an implementation plan.
