When different people are using different metrics for the same event, confusion ensues.
To give a simple example if someone hires a personal trainer to help them lose weight and 2 months later the trainer announces they have been successful because the person body mass index is much better, the person might be a bit upset since their emphasis wasn’t on BMI but rather was on losing weight.
In business, when one person is judging based on “style points” and another is judging based on results, differences will cause problems.
It’s important to make sure people are using similar metrics to evaluate a project.
Have a great day!
