Is the solution hidden in plain sight?
When I talk to Visual South customers about using their ERP system to guide them to manufacturing process improvements that could be made, I always ask who is responsible for the variance in estimated vs. actual costs in a completed work order. In some cases, I get a quick answer with a name. That speaks volumes to me because it means they are proactive in looking at cost data. Companies who do this become comfortable with the accuracy of the data. This doesn’t mean they like all the data; but that’s the point. If there is an unacceptable variance, they find out what caused it. Perhaps the standard was wrong (in either direction). Perhaps the execution was flawed or exceeded expectations. The important thing is they know about it, and can do something about it.
