Cost Estimation for Projects: How to Estimate Accurately

Good cost estimation is essential for keeping a project under budget. Many costs can appear over the life cycle of a project, and an accurate estimation method can be the difference between a successful plan and a failed one. Estimation, however, is easier said than done.

Zen Project Management

I started thinking about how common it is for people to not be able to provide good estimates. It was ironic, but part of the work with my client that week was explaining the technique of relative estimates using t-shirt sizes and story points. The team I was working with was new to agile and used to the old way of doing absolute estimates, which as we all know are not as accurate because of things like student syndrome or Parkinson's Law.

Estimate everything?

Musings on Project Management

Mike Cohn on estimating (from his email blasts): "Because I've written a book on estimating, people seem to think I estimate everything on my product backlog. I ask a team to estimate a product backlog item only when having the estimate will lead to actionably different behavior. So, for example, I might ask a team for an estimate on a user story so that I can decide if I want. agile estimate

Everyone estimates!

We all make estimates; and we all make estimates all the time. When I make the 20 mile trip each Tuesday to a client site, I estimate adjustments to a baseline based on weather and road construction and if I know about an accident. Really, no one sets out to do anything meaningful without some estimate in mind re time, or cost, or risk; usually we can also notionally estimate the scope. So, agile estimate

3-point estimates. good for you!

Musings on Project Management

Here's my three point estimate paradox: We all know we must estimate with three points (numbers). so we do it, reluctantly None of us actually want to work with (do arithmetic with) the three points we estimate. In a word, three point estimates suck -- not convenient, thus often put aside even if estimated -- and most of all: who among us can do arithmetic with three point estimates?

Estimates. An Estimate is a value inferred for a population of values based on data collected from a sample of data from that population. The estimate can also be produced parametrically or through a simulation (Monte Carlo is common, but Method of Moments is another we use). . Estimates can be about the past, present, or future.
