Ever ask yourself what's the difference between a motivated team member and an unmotivated team member? [youtube 3pvNScJgcgo]
I guess if you are a drill instrutor in the marines that works, but, as far as I know, that doesn't work in other situations.
A leader who knows the "why" and not just the "how" is what will motivate people. I know that feels elementary, but it is an incredibly effective tool for changing the way people do something. When we are clear on the "why" we teach people the reason we are doing something. If we only focus on the "how" than we communicate to people that they are a means to an end. That leaves people feeling like their personal value is secondary to the organizational need. But without people there isn't an organization or a team.
Can I recommend something? The next time you find yourself really frustrated that people aren't doing things the way you think they should be, instead of ripping people on "how" they should be fixing it, remind them of the "why" it's important that it gets done.
