Oh yeah. Sales sets the ship date, which is 'set in stone' because of a trade show. PM makes a schedule that makes the ship date. PM shows the schedule to engineering and is told it's not possible. PM tells management what engineering said, and management tells the PM to make it work, we need to give sales what they need. Oh, and you can't add more engineering resources, the project isn't that important. PM tells engineering to 'make the schedule work' and we add time to some tasks, but then necessarily take time from other tasks. Then engineering starts the death march, with everyone dreading the inevitable escalation of complaints about the project being late. Start slipping schedule? Let's have a bunch of meetings to rearrange the schedule so we can pretend for a week that we're not behind and let the PM feel good when he gives the weekly update to management.
Of course there's blame on the engineering side of the table too. We chronically underestimate effort, not adding enough margin for unknown-unknowns. So we start working late. Sandbagging estimates. Telling the PM whatever he wants to hear just to end the meeting and get back to work.
Impossible schedules are toxic for people that care, and encourage apathy as a coping mechanism. If you put in a Herculean effort and ship on time you did what you said you were going to do, what, do you think you deserve a cookie or something? The other option is failure. Even if the PM or management isn't upset, engineers still feel the failure of not hitting a goal.
Engineers need to feel wins. Always shipping late because of impossible schedules means no project is a win, no matter how good the design is.
At a former job I found out after a couple years that impossible schedules was a business strategy by the c-level execs. It encourages engineers to work as 'efficiently' (i.e. as much) as possible. God forbid we clock out early because we're not stressed out about being behind. Learning that made me shift from caring to apathy. I left shortly after, but I wish I had stayed a bit longer, it might've been nice to have a job that I didn't care about so I could focus on other areas of my life.
