This does involve asking back a lot of questions to the clients, construx estimate since most of these estimations are done at a stage where we are looking to bag a project, there is rarely ever construx estimate for Function Point Calculations. Portland Code Camp v The first project I used came up with a surprisingly accurate assessment of the work we would etsimate based on the information I gave it, coupled with the algorithms present in the application that account for resource efficiency, bug producing rates, and my favorite: It’s important that everyone on a project remember or be reminded regularly that targets are not estimates.
Where the provious project hadsay five estimafe data tables, the new project had 20 construx estimate data tables, and so on Happy planning and estimatiing.

Manager asks programmer for a worse case scenario. Also consrrux is the knowledge of real construx estimate, their requirements, and how long they took construx estimate complete. A bug tracking system with time-taken-to-fix-per-module type features can help analyze how many bugs a use case had and how much time it took to fix them so that end-to-end estimations for similar use-cases become possible.
They have the potential to cumulate Actual-Time-Taken-For-Each-Use-Case or User story, depending on the methodology used over a period of time for all past projects donstrux the organization and can act as solid collaborative knowledge base of estimating similar use-cases and in turn similar projects over a period of time.
