Case study interview and outline template for ecommerce agencies
Use this case study interview and outline worksheet to document a real engagement with evidence, permission and a clear account of what changed. It is written for ecommerce agencies and starts with an illustrative offer: a store conversion and merchandising review. Replace the assumptions with evidence from your own business before using the result.
Leave with a case study outline ready to populate with verified customer evidence.
Start with a real buying situation
For the worked example, the audience is the owner of an online store. Their problem is that customers hesitate at product selection or checkout. The desired practical outcome is a prioritised set of customer-journey improvements.
The example is deliberately bounded: changes must preserve payment, inventory and fulfilment integrations. That condition should influence the promise, scope and next step rather than disappear from the marketing copy.
| Illustrative offer | a store conversion and merchandising review |
|---|---|
| Buyer question | Where does a customer need information that the store does not provide? |
| Possible evidence | a recorded walkthrough with observed friction and a testable hypothesis |
| Useful asset | a product-page and checkout review checklist |
How to complete your case study interview and outline
- Obtain permission for the specific material you plan to publish.
- Describe the original situation and constraints.
- Record the work performed and who contributed.
- Use verified results with definitions, dates and limitations.
- Explain what another buyer can learn without implying the same result is guaranteed.
Worked example
These entries are illustrative planning material, not research findings or customer results. Keep the structure and replace the content with verified details.
| Permission and scope of disclosure | Obtain the customer’s permission for names, quotations, screenshots and figures. This worksheet contains no actual customer result. |
|---|---|
| Starting situation | Document the original problem and constraint: customers hesitate at product selection or checkout; changes must preserve payment, inventory and fulfilment integrations. Replace these illustrative prompts with verified facts. |
| Actions and responsibilities | Describe the actual work. Reference a store conversion and merchandising review only where it matches the agreed and delivered scope. |
| Verified result and measurement | Record checkout completion for a defined audience and period only if measured; include the baseline, period, source and what else changed. |
| Lessons and limitations | Explain what the case can teach a buyer. A heuristic review does not prove a conversion uplift. State limitations and avoid attributing all change to one intervention. |
Review before using it
A useful operational measure in this example is checkout completion for a defined audience and period. That does not automatically make it a marketing attribution metric. Define the source, period and owner before drawing conclusions.
- Can the customer verify the account, and are all numbers traceable?
- Check the delivery assumptions: Define platform access, implementation, measurement and rollback responsibility.
- Use evidence rather than promises. A heuristic review does not prove a conversion uplift.
- Discuss the draft with someone who understands the buying situation. Start with: “Where does a customer need information that the store does not provide?”
- If the next step is a trial, define its purpose. One possible starting point is to review one product category and one checkout journey.
Common mistakes and a better review
Do not fill a missing fact with an impressive-sounding number. Mark it as an assumption, explain how you will check it and give that check an owner. A short, honest document is easier to use than an elaborate plan built on unknowns.
| Watch for | Do not turn an illustrative example into a customer success story. |
|---|---|
| A real buyer concern | We only want more traffic. |
| Useful response direction | More traffic may help, but let us first check whether visitors can choose the product and complete checkout without avoidable friction. |
| Evidence to collect | The buyer’s own account, a recorded walkthrough with observed friction and a testable hypothesis, and records relevant to checkout completion for a defined audience and period. |
