Don't run the project, so it is assigned to you. Follow the standard, process to complete.
Project Manager gave the project plan at the end stage of the project. With the given dates, Testing team has to build the test execution plan. I saw lot of problems and wastage of the effort in doing the testing. Because IT/SIT/UAT all these environments doesn't have the valid test data to test. PPE you will have to do the testing in full fledged where there is a limitation of space. So we will be testing the sample test data. Based on the given plan, Testing team has to execute parallel in all three env. Lot of rework for the development and testing team.(Wastage of time) Note: 1. If you are not assigned to the project. Don't work on that project, simply screw the other person work. 2. If you don't have knowledge on testing/development/Build works, Shut your mouth.
