SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It solves the problem of making confident, stakeholder-ready technical decisions when multiple viable approaches exist and trade-offs must be clearly communicated.

Core Features & Use Cases

  • Structured 1-3-1 output: Produces a single problem framing, exactly three labeled options with pros/cons, and one explicit recommended option.
  • Actionable guidance: Includes a Definition of Done and an Implementation Plan aligned to the chosen option.
  • Use Case: When choosing between competing architecture, tooling, refactoring strategies, or migration paths, it helps you generate a recommendation that others can evaluate and execute.

Quick Start

Tell the assistant: "Give me a 1-3-1 for choosing between Option A and Option B for refactoring our service, including definition of done and an implementation plan."

FAQPage Schema
How do I structure an architecture decision with trade-offs for stakeholder communication?

To structure an architecture decision for stakeholder communication, frame exactly one problem sentence, outline three distinct options with pros and cons, and deliver a single recommendation with rationale, definition of done, and an implementation plan.

What is the best way to write a technical proposal for a migration plan?

The best way to write a technical proposal for a migration plan is to use a one-three-one structure: define one problem, compare three viable approaches, and select one recommendation with an aligned implementation plan and definition of done.

How do I choose between competing refactoring strategies when multiple approaches are viable?

To choose between competing refactoring strategies, evaluate exactly three labeled options with explicit pros and cons, then resolve the ambiguous trade-offs by selecting a single approach with a matching implementation plan.

Can I generate a definition of done and implementation plan for tool selection decisions?

Yes, you can generate a definition of done and implementation plan for tool selection decisions by reframing the technical trade-offs into a single recommended option, which includes actionable guidance for execution.

When do I need a structured recommendation format for technical proposals?

You need a structured recommendation format for technical proposals when multiple viable architecture approaches exist, trade-offs must be clearly communicated, and stakeholders require confident, actionable guidance to evaluate and execute the decision.
