| Software development cost: how much? You sure? | |
| Point of Contact |

| Dates | January 2005 - December 2007 |
| Problem | Experience has shown that the most expensive bad decisions are made earliest in the software lifecycle. For example, it a project's costs are under-estimated then developers will be forced into many quality-threatening cost-cutting measures as the project commences. One reason for poor cost estimation is that, all too often, NASA's software managers don't have enough relevant data to make totally accurate estimations. |
| Objective | High level objectives- to know exactly the budget allocated for NASA projects such that they can deliver high quality software. Lower Level objectives: * To build a repository of software cast estimation information that NASA managers can access to better estimate develop times for their projects * To develop a set of sensitivity tools that not only return a cost estimate, but an estimation of the error in that estimate. * Using that sensitivity tool, precisely define the amount of data needed to perform adequate cost estimation. |
