I work in one of those companies where any employee can suggest a project idea to management. My idea has been very successful, and it's now being pushed in front of the CEO. The thing is... even if this project starts, I won't be leading it. I work in a sales organisation, and it's very likely that some other colleague, working in Engineering or Product, will own this once the project starts. Moreover, even if this project is projected to bring A LOT of money to the company, this is not linked to my career progression, or to any bonus.
I am aware that many companies have this kind of initiative. So, the question is: is it worth at all participating in these initiatives, when there is no commitment from the employer to reward a successful proposal? Or, should I just put together such a proposal when I am already in a role where my involvement is already formal?
