Our project using Agile methodology, we have every day stand-up meeting(scrum meeting) that normally end around 10 to 15 minutes with 7 ppl.
One day The Project Owner came and join our stand-up meeting that cost us like sprint planning
And The Project Owner did not stop there, he come again next day for the 1 week.
Because of that our product backlogs and Sprint Planning goes haywire.
We failed to delivery what we planned for that project.
