You're a manager of people. Somebody on your team is just muddling through, meeting expectations and basically doing average work. They're capable of more. They don't seem to be feeling your "up with people" or "A-player" only vibe.
You're telling them what great performance looks like in multiple areas. You look across the table and all you see is a zombie who's wondering what the special is at Buffalo Wild Wings at lunch. You've become Charlie Brown's teacher - that's what they hear when you talk.
What do you do?
You're only shot is to tell them what's in it for them if they chase the higher performance level you're promoting. What do they get if they chase that? That's what you have to figure out and promote.
It's a problem of motivation.
Figure that out and properly position it - and you have a chance to get better performance.
If they're still not responsive, you've got a ditch digger. And the world needs ditch diggers too.
But do you need a ditchdigger? That's another post for another day.
