Overview

Use this Microsoft Excel spreadsheet for performing function point counts on all major software projects

regardless of which technologies you will use on your project. Function point counts can be applied to anylanguage you will be using for development, including C#, Visual C++, Java, SQL, C, Perl, COBOL, Visual Basicor any other language you use. You will need to understand how to apply the fundamentals of function point

counting before you can effectively use the spreadsheet. For more information on how to count function points,

Lexital is making this spreadsheet available to anybody who wants to use it. We guarantee that if you use thespreadsheet without making any modifications, the results of the unadjusted function point count will be 100%accurate according to version 4.1.1 of the Function Point Counting Practice Manual. Please note that thisspreadsheet only supports unadjusted function point counts; not adjusted function point counts. You may modify

the spreadsheet to better suit your customized needs. However, once you have modified the spreadsheet in any

The spreadsheet also includes a beginning estimate of how many hours your project team will need to completethe software project. This estimate is broken down by 8 tasks that your team's manager may want to perform onthe project. You may enter your projected project start date, number of staff, and the average weekly hoursworked by each staff member to view an estimated project completion date. Additionally, you may enter rates ofpay and known project expenses to see estimates of your project's costs. These estimates should not be usedas your final project estimates. They can, however, help to guide you in the early planning phases of your projectto give you an idea of a reasonable number of hours to allocate for the project. We do not guarantee that you will

Additionally, all estimating of software projects should be integrated into a thoughtful risk management program.The main point to remember regarding the interface of estimates with project risks is that if any of the known risksmaterialize, your estimates should be adjusted to add time to the schedule to recover from the damage sufferedby the materialization of the risks. Since our spreadsheet does not consider your risk management program, this
