Stacey’s Matrix: Seeing Complexity Clearly

In a world where not all problems are created equal, Stacey’s Matrix offers a simple yet powerful lens: Is this clear? Is this known? If the answer is no, then it's time to change how we lead.

This tool helps teams and leaders understand where a challenge sits on two axes:

  • Requirements (What): Are they clear or unclear?

  • Methods (How): Are they known or unknown?

When both are clear, go with proven processes. But when things are unclear or complex, predict-and-control fails. Here, adaptation, experimentation, and collaboration become vital.

  • Because every day, we face decisions. Some need precision. Others need humility. Stacey’s Matrix reminds us:

    • Simple? Delegate it.

    • Complicated? Plan it.

    • Complex? Explore it.

    • Chaotic? Stabilise first.

    It brings clarity to conversations, prevents overengineering, and unlocks better choices—faster. Whether you're building policy, launching a product, or navigating a community crisis—this matrix helps you lead with awareness, not assumption.

    It’s not just a framework. It’s a daily reminder: meet the system where it is—not where we wish it were.

    1. Name the Challenge — What decision or problem are we facing?

    2. Map It — Ask:

      • Are the requirements clear?

      • Are the methods or solutions known?

    3. Place It — Use the answers to locate it on the matrix (Simple, Complicated, Complex, or Chaotic).

    4. Choose Your Response — Match your approach:

      • For Simple, use best practice.

      • For Complicated, bring in experts.

      • For Complex, experiment and learn fast.

      • For Chaotic, act swiftly to stabilise, then reassess.

    5. Reflect — As things evolve, the placement may shift. The power is in returning to the matrix—again and again.
