My company is split into two teams: sales and products. Sales has the responsibility for creating leads, follow ups, and closing a sale. Product is responsible for learning and teaching everything about the product and using that knowledge to support Sales in making a sale.
Previously when the company was still small we gave commission to both Sales and Product to fill in gaps that Sales can not yet fill because of a lack in numbers. Now we have enough Sales people and I want Product team to focus 100% on mastering our products and not spend half their time chasing leads. Because both teams currently get commission they do not cooperate optimally. There's a lot of strife between the two teams, such as racing to close a sale individually so they don't have to share the commission, and so on.
How can I create the most optimal incentive schemes, one for each team, that don't reduce their current earnings, promote individual and team achievement, and best cooperation? Examples would be appreciated. Thank you very much.
