Two days sounds lucky. I've been in SAFE plans where it took an entire week to plan things, it was unreal. Like you I met people I've never seen or heard of from the company all giving their input on software I'm creating. I'd never see them again until the next SAFE planning, only this time it felt like 1 SWE out of maybe 15 (yes there were only 3 teams of 5 devs, put 100+ in these SAFE meetings) contributed anything meaningful.
Company wasted so much money, then the org shut down for spending $500 per customer per year in maintenance (this was a health insurance company) whereas the main company would only spend $70 per customer per year. You'd think leadership of the org would get fired for this but they were rewarded with other positions within the company to do the same thing.
Unreal. Why do shareholder's put up with this? I guess the healthcare monopoly is the only reason to.
