Test types and execution
Concept Development and Testing · 45–60 minutes
Today’s outcomes
- Explain test types and execution in the context of concept development and testing.
- Compare a product decision using the source outcome rather than intuition alone.
- Produce a reusable section of a concept-test brief.
Source trace
W06-O02Describe the different types of concept tests and how to conduct the most common type of concept test.
Core lesson
Make the choice inspectable
Test types and execution matters when it changes a real allocation of attention, money, time, or delivery capacity. Test the promise before investing in the complete delivery system.
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: Describe the different types of concept tests and how to conduct the most common type of concept test.
What decision will test types and execution improve, what evidence is sufficient for that decision, and what is the cost of being wrong?
Worked example
Test types and execution in practice
For a marketplace for verified repair professionals, the product manager must compare a choice about test types and execution. 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 test types and execution 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 test types and execution?
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.
