#VUBMTPQMBOOJOHJTOFFEFE GPSNBLJOHEFDJTJPOT Estimating and planning are not just about determining an appropriate deadline or schedule.

It is significant to me that much of why we do estimates is that we need to make decisions: To decide something. In other words, it looks to me that what we need are decisions , not estimates. 8PPEZ;VJMM8IZEPXFOFFEFTUJNBUFT
