When you define a product roadmap, you also define the release dates for your product. Change happens. Your market changes, your customers change, your requirements change. Unpredictable events happen. Your competitors release a new killer feature, your developers have an epiphany (or run into a roadblock). Should you change your release schedule?

We create project dashboards all the time to show status, or to give upper management an update. Dashboards and scorecards are great for giving us a “quick view” into the health of a project - they give us a way to drill down. Many of us use the colors red / yellow / green, with a stoplight metaphor. The problem is that some of us are colorblind. Johanna Rothman gives us a GREAT tip.

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.

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 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 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.

The environmental factors that describe your development team and environment are the second thing you assess when doing project cost estimation with use case points. Environmental factors primarily focus on the capabilities of your team, but also touch on your process.

The technical factors are the first thing you assess when doing a use case point analysis. Technical factors describe the expectations of the users for the delivered software. Generally, it is an assessment of non-functional requirements. There are 13 technical factors that you have to analyze. Read on to see how.

Estimating the amount of work required to deliver software is hard. Estimating the amount of work in the very early stages of a project is even harder. A method was developed to estimate the amount of work required by analyzing what the system will allow its users to do. That method is called Estimating With Use Case Points. This article is an introduction to the concept.
