Teams are built on mutual respect for each others functions and what they mean to the overall success of the company or brand. It is absolutely essential everyone knows the best idea can come from any one or any function. There is no such thing as a bad idea, as any idea can be the building block for expanding into another thought or idea. It is also key that the corporate mentality is “tell me what you can do, not what you cannot do”. Although clearly defined roles are key to creating a good team that does not mean the best ideas only come from the responsible function. Be open to suggestions or ideas, especially if they come from a user of the product.
