In my experience when something is proposed as a best practice, then it implies that every other practice is inferior by default. However, if everyone is doing the same best practice, it leads to conformity. The uniqueness that makes up your company now disappears.
Excellent Question: How can our business outperform the competition if it is using the same best practices as everyone else in your industry? The answer is, it can’t. This applies to every area of your company where you may choose to apply them. HR, Accounting, Marketing, Social Media, or IT can all succumb to applying a perceived easy way to invoke order.
