This isn&#x27;t a new problem.  I used to have to enter my time in 3 places.  Once for the client&#x27;s corporate system, once for the project-based system, and once for my company&#x27;s system. As much as we like innovation, this is part of the case for standardization.  :-)<p>The mental model I follow is:<p>1 - Figure out if you can fight it.  If it&#x27;s a fight you can win, push to standardize.  If it&#x27;s one you can&#x27;t, don&#x27;t waste your time.<p>2 - If you don&#x27;t fight it, figure out which have data that is really being used, and which people are just going through the motions.  For the data that&#x27;s being used, keep it current and think through the input.  For data that&#x27;s not, don&#x27;t kill yourself.<p>3 - Always have your own #s so that you can answer what&#x27;s really going on.
