FAQPage Schema
How do I structure a technical proposal for architecture decisions?

To structure a technical proposal for architecture decisions, use a 1-3-1 format: define one clear problem statement, list three distinct options with pros and cons, and conclude with one concrete recommendation. This ensures all trade-offs are evaluated systematically before committing to an implementation plan.

What is the best way to compare technical options for tool selection?

The best way to compare technical options for tool selection is to evaluate three distinct approaches side-by-side, documenting the specific pros and cons of each. This structured decision-making approach clarifies trade-offs and leads directly to a concrete, defensible recommendation.

How do I create a decision-making document with a definition of done?

You can create a decision-making document with a definition of done by generating a structured technical proposal. This document includes a concrete recommendation, an implementation plan, and clear criteria for completion to guide the engineering team effectively.

When do I need a structured trade-off analysis for software engineering?

You need a structured trade-off analysis for software engineering when you must choose between multiple approaches for a technical project, such as selecting an architecture pattern or implementing a new application feature. It provides a clear problem statement and three viable options.

What do I need to provide to generate a 1-3-1 technical proposal?

To generate a 1-3-1 technical proposal, you need to provide the specific problem you are facing and the relevant context of your technical project. This allows the structured decision-making process to output accurate options and a tailored recommendation with an implementation plan.
