I proposed a BHAG to my employer (whom I've known for years prior to employment) back when I was hired on.
She was ecstatic, but my immediate supervisor was not convinced. It has since been dropped as an idea (not officially, but for all intents and purposes the idea has been phased out of any real plan), and I'd like to pick it up as a personal project.
However, I'm worried about rights and such. I don't want to get far into the BHAG in a personal context and create tension with the company in any way. Knowing that going to my CEO and presenting to her a "request for rights" agreement, or something to that effect, wouldn't necessarily hurt relations, I'm wondering if that's the right thing to do.
Knowing how I work, the project wouldn't interfere with work, but I don't want to bring something up that will make them feel uneasy. On the other hand, I don't want to run into legal/IP battles down the road if I do go ahead and develop the BHAG on my own in the event it actually turns into something.
Obviously this is hinged around the existing relationship with the employer, of which is just fine. We get along on a personal level and a professional level - we also keep them very separated, which keeps the relationship strong to begin with. I just worry about looking like I'm undermining the company in some way - which isn't at all my intention.
How should I approach my employer to get rights to this project? Is this even a good idea in the first place?
