SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill resolves decision paralysis and communication gaps during technical planning by enforcing a structured, objective-focused framework for evaluating competing strategies.

Core Features & Use Cases

  • Structured Trade-off Analysis: Forces the evaluation of three distinct options with clear pros and cons.
  • Actionable Recommendations: Ensures every proposal concludes with a concrete implementation plan and definition of done.
  • Use Case: When a team is debating between three different database migration strategies, this skill generates a concise 1-3-1 report that highlights the best path forward based on specific project constraints.

Quick Start

Ask the assistant to provide a 1-3-1 analysis for choosing between a monolithic or microservices architecture for your new project.

FAQPage Schema
What is the 1-3-1 rule for technical decision making?

The 1-3-1 rule is a structured decision-making framework that produces one concise problem statement, three distinct alternatives, and a single actionable recommendation. It resolves decision paralysis during technical planning by enforcing objective-focused trade-off analysis.

How do I evaluate architectural trade-offs for a technical proposal?

To evaluate architectural trade-offs, use the 1-3-1 framework to generate three distinct options with clear pros and cons. This structured approach ensures alignment between technical choices and your project's specific definition of done.

Can I use this structured framework to compare database migration strategies?

Yes, you can use the 1-3-1 framework to compare database migration strategies. It evaluates competing strategies based on specific project constraints and concludes with a concrete implementation plan highlighting the best path forward.

What is the best way to structure a technical proposal with multiple options?

The best way to structure a technical proposal is using the 1-3-1 logic, which formats your analysis into a concise report. This ensures every proposal concludes with an actionable recommendation and clear implementation steps.

Does this trade-off analysis framework work for choosing between monolithic or microservices architecture?

Yes, this trade-off analysis framework works for choosing between monolithic or microservices architecture. It facilitates the evaluation of multiple architectural options by producing a structured problem statement, alternatives, and a single recommendation.

When do I need a structured framework for technical planning?

You need a structured framework for technical planning when experiencing decision paralysis or communication gaps. The 1-3-1 rule enforces an objective-focused evaluation process for competing strategies to ensure alignment on project constraints.
