Probabilistic Project Sizing Using Randomized Branch Sampling (RBS)
Analyzing all the stories in a project requires significant time. How can we estimate the size of a project without prior identification and analysis of every single user story? If you don't want to analyze all user stories in your project in order to estimate its size then Randomized Branch Sampling is an approach you can use for portfolio related decisions and quotations on prospect projects.

The Resurrection of Product Risk Analysis
Product risk analysis (PRA) is not only useful in testing but is also applicable during the various phases of sequential or agile system development. This article introduces a different application of PRA that elevates it from project level to domain level. It shows how you can go from risk and requirement-based testing to risk and requirement-based development.

Burn-Down or Burn-Out? How to Beat the Red-Sprint Agile Anti-Pattern
There are ways to obtain sustainable pace beyond scrum that can help stem the increasing number of failing scrum projects.

The Problem of Power Consumption in Servers
Power consumption by servers is of increasing concern to business and IT management. This Intel article discusses the sources of power consumption as a function of server form factor and workload; power consumption of other components, power supplies and conversion, plus heat generation and cooling demands. How to estimate consumption and design factors affecting consumption are also covered.
