In startups, you have no time to waste. Every day counts. The opportunity cost of lost time is huge. Startup life can be short and fragile. So, one way to get things donequickly is to communicate in an effective manner. I was thinking about this today while I was at The Wharton School serving as an Entrepreneur-in-Residence and talking about a lot of lessons learned at Bazaarvoice and Coremetrics. As I wrote about in this Lucky7 post, Bazaarvoice was one of the most capital efficient companies leading up to the IPO as compared to many companies that reach this milestone. Certainly one of the reasons this was the case is we wasted less time than most companies in how we chose to communicate with each other in order to get things done quickly.
