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.
