>If you want to see if the tools work, why don't you just ask your employees? Like any normal employer would?

I run a small business with two employees.

N=2 here, of course, but one of them will experiment with any new process you introduce (as well as plenty more that you don't!)

The other will keep doing what he's always been doing, even if it's frustrating and inefficient, unless you monitor him and force him to use the new process.

I could imagine most "normal employers" would understand that both type of person exists and, assuming you're getting good first impressions from group A, it's usually better off in the long run to shove the new process down group B's throat.

(This isn't to say that the "Group B" employee is less valuable or anything - he is more conscientious and reliable than anyone else we've ever hired - but just that different people need different management styles)
