The problem
Case studies are among the most powerful marketing assets a consulting firm can have. A well-written case study demonstrates capability better than any credentials page, because it shows you doing the work rather than just claiming you can do it. Prospects read case studies to see themselves in the client's situation and to believe that you can help them.
Most consulting firms have far fewer case studies than they should, for a simple reason: by the time you find time to write them, the project is six months in the past, the client contact has moved on, and the specific details that made the story compelling have blurred. You know roughly what happened, but the crisp before-and-after you need for a good case study is gone.
The solution is to capture the raw material immediately after project close, while everything is fresh. This workflow makes that capture quick and the write-up even quicker.
The system
Step 1: Capture the raw material at project close (Otter.ai / Claude)
Within one week of project completion, spend 10 minutes recording a voice note (using Otter.ai) or typing a rough briefing note answering these questions:
- What was the client's situation before the engagement? What problem were they trying to solve?
- What was the specific approach we used?
- What was the tangible outcome? Use numbers where possible.
- What was the most challenging moment and how did we handle it?
- What would the client say about the experience?
- Is there anything particularly distinctive about what we did on this project?
Do not edit or polish. Just capture.
Step 2: Generate the case study draft (Claude)
Paste your raw notes into Claude:
"I am writing a case study for a consulting firm's website and pitch documents. Here are my raw notes from a completed project:
[paste your notes]
Write a compelling case study in this structure:
- Headline: A punchy summary of the outcome (not the problem)
- The situation: 2 to 3 sentences on the client context and challenge
- The approach: 3 to 4 sentences on what we did
- The results: Key outcomes, ideally with specific numbers or comparisons
- The insight: One sentence on what made this engagement distinctive
Write this for a potential client reading it on a website. They are assessing whether we have relevant experience for their own challenge. Be specific and concrete. Avoid consulting jargon. UK spelling, no em dashes."
Step 3: Create a long-form version for pitch documents (Claude)
"Now expand this into a longer case study (400 to 500 words) suitable for a proposal or credentials document. Add more detail about the challenge, the methodology, and any interesting moments in the project. The tone can be slightly more narrative and less punchy than the website version."
Step 4: Build a visual case study card (Gamma)
For pitch presentations, take the short version and build a one-page visual case study in Gamma:
"Create a professional one-page case study card for a consulting firm. It should have: a compelling headline, a brief description of the client situation, three to four bullet points on the approach, and three to four key results. Use a clean, modern design."
Export the Gamma output as a PDF for inclusion in pitch packs.
The results
Before: Case studies written months after project close (if at all), missing the specific details that make them compelling.
After: A complete, website-ready case study written within a week of project close, taking 30 minutes from notes to finished copy.
The timing difference is enormous. The raw notes you capture in the week after project close are infinitely richer than what you can reconstruct six months later. Numbers are accurate. Specific challenges are memorable. The client's actual words are still in your notes.
One consulting firm committed to writing case studies immediately after every project and built a library of 20 case studies over 18 months. Their proposal win rate improved notably because every proposal could include directly relevant case studies from similar engagements. Generic credentials pages do not win business; specific, evidenced stories do.
