This comment actually suggests a useful question to ask when you find yourself in a situation where a group has decided on something but nobody is acting. Is the task to do:

a) Impossible, like for a mouse to put a bell around a cats neck, or

b) Possible but just not something people want to do.

In scenario (a) you need to move on from the idea, or fundamentally change it. In scenario (b) you can deploy organizational tools to get someone to do it (provide an incentive, force someone, draw straws, share the work etc).

reminds me of High Output Management by Andy Grove: (paraphrasing from memory) if someone isn't doing their job they are either not capable or not motivated
