As for topics to brainstorm, I would caution that this exercise will be critiqued by all those involved and those at the top (you only get one chance to make a first impression kind of thing) and since you’ve got engineers all around you wondering what value this will really bring, you might be wise to strategize…I’d shoot for a product that could potentially be seen as growth in a near category to whatever products are the company’s core strengths. Real and tangible but not what they already do/make.
