I was recently asked, if you roll-out some kind of idea scheme, approach or system and 20 or 30% people don’t adopt, what is likely to be the impact?
It depends who they are.
If they are your people at the front-line don’t worry. It’s unlikely to have a huge impact. There are very few engagement ‘tools’ (that don’t involve alcohol) that can successfully engage everyone.
BUT (and it’s a big but) if you fail to engage even 20% of the middle managers, you are doomed.
If they don’t want ideas (or don’t want the perceived disruption that ideas bring), don’t ask their staff for ideas.
If they say they want ideas, but don’t commit to following-up (and I would suggest that they also understand the implications if they fail) and implement some ideas, don’t ask their staff for ideas.
Sorry to be blunt, but it’s as simple as that.
