What is a Decision Stack?

A Decision Stack is a five-layer strategic artefact created by Martin Eriksson. It connects vision to daily decisions. Lunastak uses it as the structure for everything it builds.

The first build writes the top three layers: Vision, Strategy and Objectives. Opportunities are drafted on request, with Generate with Luna, or added by hand. Principles are yours to add. Watch a Decision Stack being built (video, opens in a new tab)

The five layers

Vision

One sentence about where the organisation is going. The north star for every decision below.

Strategy

The coherent set of choices that explain how you'll reach the vision. Not a list of goals — a theory of how you win.

Objectives

Measurable outcomes. Each has one metric that matters and an aspiration. Objectives make strategy testable.

Opportunities

Hypotheses with belief statements and success signals. What you actually try to move the objectives. Watch opportunities generated (video, opens in a new tab)

Principles

Operating guidelines as "X even over Y". The decisions that reveal real priorities under trade-off. Watch a principle added (video, opens in a new tab)

The strategic areas

Behind the five layers sit eleven areas of strategic context. Lunastak tags ground truths with the areas they cover and uses them to populate the layers. An AI assistant you set up with one paste extracts ten of them into a context bundle. Differentiation & advantage has no bundle key; Lunastak tags it when it reads your chats and documents.
