Backstory: Offering manager brings a project through a few months of requirements gathering / feasibility study etc. Project spends 8 months with a R&D team to flesh out. Our team gets 6 months to turn it into a ship able product. 4 months in, offering manager calls a meeting.

OM: ok so you are all working on project X, well I need your input on something

Team: Ok, go ahead

OM: what do you think the app needs to do?

Team: ... I'm sorry?

OM: well we've been looking at it, and we don't think it does very much compared to existing apps. We need a killer feature but we don't know what. Any ideas?

Team: well we were looking at project Y originally, which was a lot more advanced. But you pulled the plug in favour of this.

OM: yeah, believe me customers will want project X a lot more. It just needs to do something interesting ... you know what I mean?

Team: not really, if it doesn't have anything, why did we go for it?

OM: ok I don't think I'm being clear. Point is, if anyone has any ideas let me know, we need to ship it in 2 months and it needs to be killer

I handed in my notice that week and was asked why ... let's just say I told them.
