When you are discussing a potential business improvement idea it can often be worthwhile to put the idea in someone's head and leave it there for a while.
The mind usually solves problems at its own rate, and giving people enough time to mull it over can usually produce better improvement idea results than when we force people to agree in a meeting situation.
Developing the ideas in a two part strategy can appear to be slow and sluggish, but is another example of the 'tortoise and the hare' in action. Better solutions are worth the (short) wait.
Of course, don't employ the very common alternative (to the one off meeting approach) of the infinite meeting method. This is where you never close the loop to commence work on a project!
