SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Run time-boxed technical experiments to de-risk unknowns before committing to a design or implementation plan. A spike answers the question: "Will this actually work?"

Core Features & Use Cases

  • Identify and document risky technical assumptions.
  • Design minimal experiments to validate or deny those assumptions.
  • Compile evidence and deliver a concise spike report to inform design decisions.
  • Reference related context and documentation to avoid known gotchas.

Quick Start

Identify the riskiest assumptions, then run a time-boxed spike to validate them before committing to design.

FAQPage Schema
How do I validate technical assumptions before committing to a software design?

You can validate technical assumptions by running time-boxed spikes that design minimal experiments to test risky unknowns. This process identifies assumptions, executes targeted experiments, and delivers evidence-based verdicts to inform your design decisions before implementation.

What is a time-boxed spike for de-risking software engineering projects?

A time-boxed spike is a focused technical experiment used to de-risk uncertain outcomes before committing to implementation. It answers whether a specific approach will work by designing minimal experiments, executing them in parallel worktrees, and compiling evidence into a final spike report.

How do I evaluate external APIs and library integrations for feasibility?

To evaluate external API and library feasibility, run structured technical spikes that identify risky assumptions and design minimal experiments. This validates integration outcomes through evidence-based verdicts, ensuring uncertain external dependencies are tested before full design commitment.

What is the best way to run proof-of-concept experiments for risky technical features?

The best way to run proof-of-concept experiments is using a structured spike workflow that identifies assumptions, designs minimal tests, and executes them in parallel worktrees. This delivers evidence-based verdicts and a concise spike report to inform your design decisions.

When should I run a spike during the design brainstorming phase?

You should run a spike during design brainstorming or concept reviews when evaluating uncertain outcomes like external APIs, libraries, or integrations. Running time-boxed experiments de-risks these unknowns by delivering evidence-based verdicts before you commit to a design.

What limitations should I consider when using spikes for risk assessment?

Spikes are limited by their time-boxed nature, meaning they provide minimal experiments rather than full implementations. They focus strictly on validating or denying technical assumptions to deliver evidence-based verdicts, so they should not be treated as production-ready code or comprehensive design documents.
