Ah the joys of customers having unrealistic expectations. A short snippet of an extended conversation today.

PM: We have to get this done in the next sprint

Dev team: That's not technically feasible. We need a minimum of 4-5 just for development.

PM: That's not acceptable to Customer. We have to get it done sooner than that.

Dev team: Unfortunately that's the soonest we can get it done.

PM: Customer will leave over this if we can't get it done sooner.

Dev team: Well...it's still not feasible to do it any faster.

This went on for at least an hour.

The best part is this functionality the customer is demanding has a very real chance of taking down the entire system when they start using it as intended and the powers that be still didn't tell them to eff off.
