Sometimes, everyone needs to jump in and help.
It doesn’t matter if it’s requirements, QA, development, data entry, trials, etc, etc.
Everyone needs to jump in if you want to be a success.
But you can’t do it all the time, otherwise, it loses its value, and then it becomes – “some hands, only these hands, maybe those hands”.
Don’t let it lose its meaning, so when you do use it, everyone knows what is expected.
