Ideas, as in the process of thinking of new things, also known as design and creativity and other words people like, vs
The Idea, which is an untouchable monolithic safety blanket common in startups, where the founder(s) are unwilling to challenge their core assumptions. This is usually because they think of creativity as a one-off moment of inspiration type affair and, through fear that it won't strike twice, stop trying.
Truthfully, you have to execute a process to have good ideas, and processes for execution are ideas themselves. There's no dichotomy except what we make when we put The Idea (or perhaps even The Execution) up on a pedestal.
