We just completed a series of articles detailing how to use Use Case Points for software cost estimation. In this article we have a free MS Excel Spreadsheet for calculating use case points. Download it today to make it easier to do your project cost estimations.

Software Cost Estimation With Use Case Points – Final Calculations
The final step in project cost estimation with use case points is to do the math. First you identify the technical and environmental factors that influence your environment and describe your team. Then you analyze the use cases and actors that describe the expectations of the software and who has them. Finally, you bring it all together to do the math.

Software Cost Estimation With Use Case Points – Actor Analysis
Software project cost estimation using use case points takes the approach of estimating the amount of effort based upon what the software is being asked to do – not an analysis of how someone chooses to do it. We’ve looked at technical and environmental factors that influence our estimate. And we’ve done a use case analysis to quantify how much work the software is being asked to do. The last area of analysis focuses on the users of the software.

Software Cost Estimation With Use Case Points – Use Case Analysis
Software cost estimation with use case points is primarily driven by use case analysis. You take into account environmental and technical factors, but they are ultimately only modifiers of the analysis done on the use cases. Each use case contributes to the project cost estimate, and use cases of varying complexity have a varying influence on the cost estimate.

Writing Functional Requirements to Support Use Cases
Background:
In our previous post, Sample use case examples, we created two informal use cases. The use cases were written to support product requirements defined as part of a project to reduce test suite maintenace costs. In this post, we will define functional requirements that support these use cases. This process is an example of using structured requirements, applied to a small real world project.
