We can assign a reasonable price for our services. We can prioritize requirements. Expected value is a calculation that should be used when calculating ROI.

3. How bad is our software, really?

Why Incremental Delivery Is Good
Incremental delivery is a key component of most software projects today – it allows us to deliver the most valuable elements of a system first, which allows our customers to start getting benefit from the system earlier. As additional features are developed, and additional use cases are enabled, they are delivered to the customers, who get incremental value from those features. This can have a significant impact on ROI projections for a project – and can be the difference between getting the deal and losing it.

Definition of ROI – Return on Investment
We talk about ROI all the time – what is it, in layman’s terms? ROI is the acronym for return on investment. Another way to think of it is “How much profit will we make if we invest in this project?” Profit is revenue minus costs. Technically, the question should […]

Describing the Software Development Process
Software development involves determining what to develop, documenting this decision, determining how to develop it, and actually developing it.We present a framework for describing this process in terms of layers of activity. Many people use pyramid analogies, which show the magnitude of effort in each layer (lines of code versus lines of requirements, for example). Many other people use inverted pyramids to reflect the importance (or impact) of work done at different layers (a sentance defining a strategy has more impact than a line of code). Some people show PERT diagrams of waterfalls or pretty circular arrows charts showing iterative lifecycles, or any of many good analogies.
