New e-mail policy.
I like this concept. Treat e-mail more like SMS, assume a character limit. Instead of trying to track characters, just limit sentences- maximum 5 sentence response.
I love the power of e-mail. When I started in my current position, I quickly realized that my boss responded to e-mail from his blackberry +90% of the time. I started posing my questions to him in multiple choice; A, B, C. I got responses from him faster than any of my peers, even on complex issues.
p.s. Each of the choices I posed to my boss were answers I was happy living with. He had control and I always won.
