Estimates are unimportant. Why? Because most conversations about estimates go thusly: Client: "How long will it take?" Dev: "Approximately three weeks." Client: "We need a firm date." Dev: "Fine, April 29th." Client: "Unacceptable. We require this functionality by April 10th." Dev: "I could only possibly do it by April 10th by having the entire team work day and night until then." Client: "Excellent. We look forward to launching on the tenth." And then, they're pissed off when you pull off the incredible and deliver a three week build in three days. Fuck everything about this business.
