I've worked with a lot of environments before where these deadlines aren't artificial. Usually these are projects dictated and agreed to by non-technical staff, then handed to technical staff to figure out. I assumed they were artificial, then I look at official signed contracts with deliverables and dates and die a bit inside.
"We said we'd give them X, Y, Z by A for $N. Let's see how close we can get to it." Is not abnormal from my experience with major clients as well. I work in R&D so there is usually an expectation of delays and failures but in this world, the client has an idea of what they want and an upper budget if what they'll spend. People try and feel this out to get as close to their budget as possible and as little as the client with agree to for that budget. Actual budgeting based on requirements and planning doesn't happen, you simply grab the opportunity and run with it. Yes, much of R&D is complete shit show.
