Evidence-first case-study blueprint

Turn Customer Wins Into Proof: The Evidence-First Case Study Interview

This blueprint guides the interview and assembles the resulting story, tying each outcome to a baseline, a time window, and an evidence owner. Fields stay bracketed until validated material fills them — no customer, result, date, metric, or industry is added here.

Headline result

[Validated metric] over [Time period] for [Client name]

Metric[Validated metric] Window[Time period] Customer[Client name]

Every outcome needs a baseline, time window, and evidence owner. Leave each token bracketed until a validated source is confirmed.

Customer context

Establish who is speaking and the environment their answers describe. Confirm the profile before capturing any outcome.

Confirm the customer identity and how they should be attributed.
Clarify the interviewee's decision authority over the work described.
Note the operating environment and constraints that shaped the problem.

Before state

Describe [Problem] and quantify where things started. A result only proves value against a measured baseline.

Ask how the situation was measured before any change.
Pin the starting baseline to a number and a method.
Name who owns the evidence for that baseline.

Measurement method

Evidence owner

Every outcome needs a baseline, time window, and evidence owner. Record the baseline here before any result is claimed.

Turning point

Capture what triggered the decision to change: an event, threshold, stakeholder pressure, risk, missed opportunity, or operational constraint.

The turning point should connect the before-state pressure to the decision to evaluate change. Keep it grounded in what the interview surfaces.

Trigger type

Event or threshold

Stakeholder pressure

Risk or missed opportunity

Operational constraint

Solution timeline

[Solution] rolled out over [Time period]. Map the phases as they actually unfolded; only the solution and time period remain bracketed.

Evidence ledger

Each row ties a claim to its baseline, time window, validated metric, evidence owner, and evidence link. A claim without all six is not ready.

Claim	Baseline	Time window	[Validated metric]	Evidence owner	[Evidence link]
			[Validated metric]		[Evidence link]
			[Validated metric]		[Evidence link]
			[Validated metric]		[Evidence link]

Quote bank

Quotes should reveal tension or change rather than repeat claims. Keep attributed client language separate from editorial interpretation, and never restate interpretation as fact.
