How to Write a Portfolio Case Study From a Learning Project
Structure any project or learning work into a concise case study that explains the problem, your decision, and what you would test next.

A case study is a decision record, not an essay
A strong case study shows how you thought about work. It explains the problem, the constraints, the choice you made, the deliverable, and what remains uncertain.
Keep it to one or two pages. If a reader can follow the decision and ask a better question at the end, the case study is working.
The five sections
Open with the problem in one or two sentences. Give the context and constraints, such as time, data limits, or the people involved. Explain your decision and the trade-off. Show the artefact with enough detail to be inspected. Close with the limits and the next test.
Label the work accurately: a learning project, a business challenge, or a proposed improvement. Never present a simulated exercise as production experience.
A fill-in template
Title: one line naming the problem and your role. Problem: what was slow, unclear, repeated, or risky? Constraints: what limited the options? Decision: what did you choose and why? Artefact: what did you create and where can a reader see it? Limit: what did you not test, and what would you do next?
The Iteretta portfolio keeps the brief, submitted work, Hiri feedback, and revision history together, so a case study can be written from a record rather than memory.
The concise case study format
- 01Problem: what was the operational or user problem?
- 02Context: what constraints limited your approach?
- 03Decision: what did you choose and why?
- 04Artefact: what did you build or produce?
- 05Limit: what did you not test or prove?
Common questions
How long should a portfolio case study be?
One to two pages is usually enough. Include a link to the fuller artefact for anyone who wants the detail.
Should every project become a case study?
No. Publish your strongest three or four. Each should show a different skill, such as process mapping, data reasoning, decision-making, or communication.
