My greatest management discovery through the transition was that peacetime and wartime require radically different management styles. - Ben Horowitz

when you are a startup executive, nothing happens unless you make it happen. In the early days of a company, you have to take eight to ten new initiatives a day or the company will stand still. There is no inertia that’s putting the company in motion. Without massive input from you, the company will stay at rest.

As CEO, you should have an opinion on absolutely everything. You should have an opinion on every forecast, every product plan, every presentation, and even every comment. Let people know what you think. If you like someone’s comment, give her the feedback. If you disagree, give her the feedback. Say what you think. Express yourself. This will have two critically important positive effects: Feedback won’t be personal in your company. If the CEO constantly gives feedback, then everyone she interacts with will just get used to it. Nobody will think, “Gee, what did she really mean by that comment? Does she not like me?” Everybody will naturally focus on the issues, not an implicit random performance evaluation. People will become comfortable discussing bad news. If people get comfortable talking about what each other are doing wrong, then it will be very easy to talk about what the company is doing wrong. High-quality company cultures get their cue from data networking routing protocols: Bad news travels fast and good news travels slowly. Low-quality company cultures take on the personality of the Wicked Witch of the West in The Wiz: “Don’t nobody bring me no bad news.

Management purely by numbers is sort of like painting by numbers — it’s strictly for amateurs.
