Agile estimation using planning poker
Story Points Uses Velocity, Prevents need for Re-estimation, Good Size Based Estimate, Allays Fear of Commitment, Drives Cross Functional Behavior among teams. The Fibonacci series is just one example of an exponential estimation scale. The reason an exponential scale is used comes from Information Theory. Estimating work effort in agile projects is fundamentally different from traditional methods of estimation. The traditional approach is to estimate using a "bottom-up" technique: detail out all requi.
Agile Estimating and Planning
You'll get better and better with time. This takes advantage of the human capacity to compare things to each other and avoids our difficulty in comparing something to an abstract concept such as dollars or days. Likewise, the team should agree that a four-point story is roughly twice as much work as a two-point story. I like the explanation at http: More on dot voting here. Oh well, the team marked that story as a 2 or 3, so I still did a good job. I would not be in favor of using time factor directly in release planning because of few reasons I have quoted in my post.
9 Agile Estimation Techniques
In Story sizing, team does a comparative analysis between all of the stories for the project. It is very important to identify one or multiple base or reference story against which you would do relative sizing of the backlog. This story is picked from current product backlog or a different story which we have done earlier.
But what is important is the understanding of this sory is same among everyone on the team. Team should be confident of this base story. Product Owner or Proxy PO, will answer questions and provide explanation about what exactly this story entails.
This is best done by Scrum Master who can add these details as and when discussions are on. How much code will need to be written for this story? Have we written similar code before? Will any special setup e. How much work is involved in helping the customer to automate the acceptance tests for this story? If this story is about the same amount of work as one you have already sized, give it the same number of points.
If it is more difficult, give it a proportionally higher value. If this story is similar to another but less work in some way, give it a lower value.

Story points help give a sense of complexity and delivering actual business value, vs. The Power and Beauty of Community. Management have to understand and change their mindset towards more Agile way of thinking. They need to appreciate what Scrum has to offer which is so natural and common sense.
Hence in organization wide agile transformation one of the biggest roadblock is how to change management mindset. Story point are very easy to follow and implement. No complex thinking or mathematical formulas required to arrive at final number.
Once again agile principle of simplicity must dawn on people. Right on about how points can help team estimate be more honest and accurate. I find that on the long run, if estimations keep being inaccurate, it could really down the morale of the team.
Avienaash, what do you think about using hours? Moreover, since hours are smaller units, overestimating will skew planning less.
