Core lesson
Make the choice inspectable
Concept-development stages matters when it changes a real allocation of attention, money, time, or delivery capacity. Products pursue continuing outcomes; projects deliver bounded change.
Start by naming the decision and the uncertainty around it. Separate evidence from assumptions, compare at least one alternative, and state what would make you revise the choice.
The source outcome for today is: Explain the concept development process of a product.
What decision will concept-development stages improve, what evidence is sufficient for that decision, and what is the cost of being wrong?
Worked example
Concept-development stages in practice
For a permissions-management product, the product manager must analyse a choice about concept-development stages. The team records the target user and outcome, the evidence currently available, the strongest alternative, and the next reversible test. The recommendation is written as a choice with a reason—not as a list of features.
Do the work · 20 minutes
Turn the idea into a decision
- Choose a product you know and write the specific decision that concept-development stages should support.
- List two pieces of evidence, two assumptions, and one credible alternative.
- Make a recommendation in three sentences and add one condition that would change it.

Answer before opening
What is the decision at the centre of concept-development stages?
A good answer names an accountable choice, not merely an activity or output.
How should evidence and assumptions be separated?
Label observed facts, interpretations, and untested beliefs explicitly so the next learning step is visible.
What makes the recommendation revisable?
It includes a trigger, threshold, or new evidence that would justify changing course.
What should the portfolio artefact communicate?
The context, considered alternatives, chosen direction, rationale, evidence, and remaining risk.
