In a corporate case study, I always want to find the thread that unites the story. A case study HAS to be a story that viewers can connect to, not just because the technology or product is relevant to them.
The people in the story, users of the solution, need to feel real and convey realness through their challenges and approach to solving them. The product’s role in that solution gains importance through association with that resolution. It fits perfectly with the thing our main characters were looking to solve. The viewer identifies with the story because they see these same challenges in their own work.
