Write Your Case Study as a Decision Story, Not a Timeline

Stop listing the steps you took. Start explaining the choices you made and the constraints you navigated.

I was sitting in a windowless conference room, surrounded by lukewarm coffee and the glowing screens of four other design leaders. We were in the final stages of hiring a Senior Product Designer for a complex B2B platform. We had narrowed the pool down to twelve candidates. Each of us was assigned three portfolios to review. The pressure was on. We had a critical product launch in two months, and we needed someone who could hit the ground running.

I opened the first link. The landing page was stunning. Beautiful typography, a clever custom cursor, and a smooth scroll animation. I clicked into the first case study. It was a redesign of a mobile banking app.

I started reading. The designer began with a lengthy introduction about the history of mobile banking. Then came the user research section. There were photos of sticky notes on a whiteboard. There were quotes from five different user personas. There was a detailed breakdown of the affinity mapping process.

I scrolled. And scrolled. And scrolled.

Two minutes passed. I was now on page fourteen of the case study, and I still had not seen a single screenshot of the final design. I did not know what the actual problem was, what the designer specifically did, or what the outcome was.
