In my experience,
Good Idea + Good Execution = High chances of success
Good Idea + Bad Execution = Low chances of success
Bad Idea + Good Execution = High chances of success
Bad Idea + Bad Execution = very low chances of success
A good idea with bad execution will not work but A bad idea with a good execution can work.
Ex- A machine that smash your face - Bad Idea
But it helped in boxing training - Good execution
So agreed with @carolina_reis - "what matters the most is the problem that product is solving."
Idea matters for the strategy & execution matters for the tactics.
You need an idea which make sense strategically:
- addressable market is big enough
- you have a differentiator against your competitors
- your revenue will be higher than marginal cost
Without this, you can have the best execution in the world, it will go to waste.
If you idea check the points I mentioned above, then execution is what will matter.
