a first time project owner sets up weekly requirements meetings for a new project. everyone has input, but the project owner. 4 months into building the application to the requirements gathered, the project owner says, that's not at all what I want. 4 months wasted

Welcome to devRant! That is bad - real bad for a PM. No excuses.

do you do sprint reviews and include the product owner? damn man, 4 months is a lot

@mwemekamp This is a company I worked for about 3 years ago and no there were no sprints. However there were weekly bench mark meetings. in those meetings pm say quietly while everyone else did all of the talking. Other stakeholders that had interest in the product, but not the requesters. Yes 4 months is a long time
