This is similar to the centralized model and used by companies with 200-500 employees, but the only real difference is that there is no core committee making decisions about the ideas. Decision making responsibility is moved over to the head of operations/management team.
The managers/lead of idea management team is provided with all the necessary resources, aiding faster decision making and taking a calculated leap. Generally, these managers/leads don’t take the final action all alone, they seek domain experts advice. Hence they formulate their own expert panel board or quickly ask for an expert opinion to undergo development process.
Key responsibilities of the executives are mainly to monitor the flow of ideas, measure the outcomes and convey the information to the managers about potential challenges and opportunities for improvement.
