This meme is so fucking true.
We're replacing an entire stack with software provided by a new vendor. Our application group was excitingly telling us the go date for new platform was August 2026 (this was in December).
Not only is it ridiculously short, considering the existing stack processes some $200m (plus) worth of business a month, but there was zero architecture work on how upstream and downstream stacks would interface (all API magic if you ask the PM). Apparently the vendor was hand waving the huge amount of integration and migration work away claiming they had an army of devs (all offshored) to handle all that messy and complex stuff.
I discovered yesterday we haven't even signed the fucking contract / settled on a price.
Lol.
And yet the bosses are like, we are go for August. Mother fuckers we haven't even started!
