I'm looking to put together case studies for all of our clients. We're a contract engineering firm. At this point I need to get our case studies approved by our clients, which brings up the following question..
What makes for the better case study? A generic mention of the client "We worked with the client.."
Or to actually put the client on there? "We worked with So-and-So to develop. So-and-so loved us!"
I would look at it from your target audience's perspective:
What are they concerned about with hiring you?
I can think of some topics I would address:
Of course it's always better to be specific.
When you say the name, not only does it feel more real, you know it is real because some lawyer and group at some company "approved" it.
Half of the purpose of a case study is to explain the pain, how you solve it, and what it looks like after. You can do that without names, and certainly that's better than nothing.
But the other half is the testimonial -- the social proof or external proof that you really are as good as you say, or at least good enough to be well worth the money and hassle.
This latter half doesn't come through unless you have a name to go with it.
How I would act if I were you:
Don't forget though, that generalized texts do not work as good as original ones. It's satisfied client speaking for you and you must use this chance to deliver your message, not the "They loved us" one.
