Empiricism and the Three Pillars
- Explain empiricism: knowledge comes from experience and decisions are based on what is observed
- Describe transparency, inspection and adaptation, and how each depends on the others
- Recognize when adaptation should happen and what makes it difficult
Scrum is founded on empiricism: knowledge comes from experience, and decisions are made on what is actually observed rather than on detailed predictions made up front. That is why Scrum suits complex work — product development where more is unknown than known — and why the framework is deliberately small. It does not tell a team how to build a product; it gives them a structure in which they can learn quickly and change course.
Empiricism rests on three pillars. Transparency means the process and the work are visible to those doing the work and those receiving it, so important decisions are based on the real state of the three artifacts. Inspection means the artifacts and progress toward agreed goals are examined frequently and diligently to spot problems early. Adaptation means that when any aspect of the process or the product drifts outside acceptable limits, the process or the materials being produced are adjusted as soon as possible. The pillars depend on each other: inspection without transparency is misleading, and inspection without adaptation is pointless. Adaptation becomes much harder when the people involved are not empowered or self-managing.
Study focus: the exam often asks which pillar a situation describes, or what happens when one is missing. Hidden work or a "done" increment that is not really done is a transparency failure; skipping or rushing an event is a lost inspection opportunity; noticing a problem and not changing anything is a failure to adapt.
