There's a huge long-term payback and yield from eliminating the root cause of errors and fixing problems that constantly repeat themselves $10,000 per hour activity. I can imagine right now some people might be like Sam no way is there things that you can do that are 100 grand an hour yes there are but remember that the yield and the payback on these things is over the long term it will pay back more than this probably so capital allocation decisions and salary and incentive decisions.
