Introduction
Only experimentation can confirm or refute the relevance of theory and established practices.Experimental Algorithmics
Theoretical questions and motivations, combined with empirical research methods, produce insights into algorithm and program performance.Empirical Studies to Build a Science of Computer Science
We learn to develop software by building, testing, and evolving models.Experience-Driven Experimental Systems Research
The most direct way toward understanding whether PlanetLab and other such systems serve their purpose is to build, deploy, and use them.Workloads (Creation and Use)
Workloads are used to estimate and measure system performance, but the results are only as good as the workloads and models being used.TREC: Continuing Information Retrieval's Tradition of Experimentation
Large-scale test collections drive improvement in search technology to help users find information in free text.How DARPA Structures its Robotics Programs to Improve Locomotion and Navigation
Research teams use common robots and machine learning to teach the robots outdoor navigation and locomotion skills.What Motivates Wikipedians?
In order to increase and enhance user-generated content contributions, it is important to understand the factors that lead people to freely share their time and knowledge with others.Information Life Cycle Management
A new framework, created to enhance information life cycle management by clarifying the relationship between value-at-risk and total cost of ownership, helps IT managers build a winning storage environment.Does Data Warehouse End-User Metadata Add Value?
Many data warehouses are currently underutilized by managers and knowledge workers. Can high-quality end-user metadata help to increase levels of adoption and use?The Impact of Size and Volatility on IT Project Performance
Studying the factors influencing project risk.Making Knowledge Work in Virtual Teams
"I've been working in computers for years, and only the simplest stuff works 90% of the time."---A virtual team leader reflecting on technology facilitation.Drivers of Price Premium in E-Markets
