Ok, So I am just fed up with these project delivery dates. These are the most irritating aspect of any project.
My current project is already delayed 3 times, because of the optimistic biases of the team lead.

Developers were forced to work over weekends. The QA cycle is taking more time than the dev cycle itself, and it's very irritating waking up with a new bug in the JIRA notifications.
Everytime we reach the delivery dates, there will be multiple bug items on each and everyone's plate that you just can't release the product.

I want to know if anyone feels the same ? How does your management takes care of these delivery dates ?
