Measuring the value of HR solutions

The best way to build broad endorsement — and gain financial approval — for new investments in HR solutions is to build a comprehensive business case that pinpoints all costs, potential benefits, and even project risks. This goes deeper than the simple calculation of ROI = net benefits/total costs, and ultimately, acts as a management tool to ensure that the project stays on course.

How to Weigh Smoke: Measuring Online to Offline Conversions

Legend has it that Sir Walter Raleigh once bet Queen Elizabeth I that he could measure the weight of smoke. To win the bet, Raleigh placed a piece of tobacco on one end of a balancing scale. He then filled his pipe with an equal amount, smoked it, and carefully tapped the ash onto the other end of the scale. The difference in weight, he said, was the weight of the smoke.

Measuring Application Performance

When considering a benchmark to determine the overall performance of a Java application, bear in mind that bytecode execution, native code execution, and graphics each play a role. Their impact varies depending on the nature of the specific application: what the application does, how much of it is bytecode versus native code, and how much use it makes of graphics. How well a JVM will perform for a given application depends on how the unique mix of these three functional areas maps onto its capabilities. Given these variables, the best way to benchmark a JVM is against your own application. Since thats not possible before the application has been written, you must find those benchmarks that are most relevant to the application you intend to write.
