More Time and Energy for Productive Activity – When teams aren't working well, huge amounts of time and energy are taken up with resolving conflict, dealing with performance issues, and remedying poorly communicated expectations. You'll have a lot more time to spend on productive activity if your people learn to work alongside one another better.
Better Fit Between Team Members and Roles – People become dissatisfied when they aren't well matched to their jobs. When you understand a person's natural preferences, it is easier to fit her with a job she'll like and will be good at. This helps improve performance and engagement.
Improved Understanding of Customers and Other Stakeholders – There's potential for conflict and miscommunication when your team comes into direct contact with customers or other external stakeholders. Knowing their own preferences will help your team members understand how to serve their different customers more effectively.https://www.mindtools.com/pages/article/newCDV_92.htm
