Time and motion study
I have reverted your addition to Time and motion study twice. While the information you've added seems quite interesting, unfortunately, in order to include that information, you need to provide what we call a reliable source that verifies the information you want to add. One of Wikipedia's fundamental beliefs is that any information which is not immediately obvious should be verified by some sort of reliable source. So if you want to re-add the info, please include a reference along with it. If you have any questions about what that means or how to add sources, feel free to contact me on my talk page at any time and I will be happy to help. Qwyrxian (talk) 09:04, 18 January 2011 (UTC)
