How well do you improve?

Are you able to identify how happy your team are at any point of the day?
How well do you know if you are going to achieve today's goals?
How effective are you at understanding whether someone has too much or too little work?
How quickly can you identify if someone has to either rework something OR duplicates something unnecessarily in their task?
How quickly do you find out if you have a broken or faulty product, or a complaint about a product or service you provide?
If you are trying to introduce a change, how engaged is everyone?
