One goal

May have multiple products but all products are aimed at a single goal.
All teams are working towards the same goal.

Multiple similar goals

Have several products (or several parts of a single product) aimed towards different goals.
Teams gain by helping each other.
The goals to some extent are complementary but (naturally with time) diverge away from each other.
The tipping point comes when the goals become orthogonal and thus, any bonding between teams working on (orthogonal) goals goes to zero.

Multiple conflicting goals

Multiple products, the success of one will kill the market for the other.
Teams gain at the expense of other teams, conflicts are high.
Interestingly, the most influential people in the company control revenue-generating goals (whose best days were in the past) and they prevent the company from focusing on goals aimed at smaller but fast-growing areas.
