"Building usability into a system requires more than knowledge of what is good. It requires more than an empirical method for discovering problems and solutions. It requires more than support from upper management and an openness on the part of developers. It even requires more than money and time. Building usability into a product requires an explicit engineering process. That engineering proc...

Performance measurement has become so widespread that it is impossible to know all that is taking place within governments across the world.1 Also, the labels and the focus of performance measurement systems shift, usually when a new government takes office. Positive, action-oriented words are usually chosen as names for such systems — 'Measuring Up' in Alberta, the 'Oregon Benchmarks', the 'Mi...

In the manufacturing and construction industries, performance measurement is used as a systematic way of judging project performance by evaluating the inputs, outputs and the final project outcomes. However, very few companies systematically measure their performance in a holistic way. Moreover, the existing systems tend to focus more on product and less on process and design. This can lead to ...

Nowadays, the user group for business performance measurement has expanded from managers to employees. However, there has been hardly any research regarding how employees are actually using performance measurement. This paper explores the topic by seeking answers to three research questions. First, for what purpose do employees actually use performance measurement? Second, what kind of problems...

A well-designed performance measurement system is vital for ensuring that organisations deliver cost-effective, high-quality services that meet the needs of service users. Without feedback on all important aspects and a system for ensuring that the organisation acts on that information, managers are struggling in the dark to improve services. However, performance measurement is not easy, partic...

In an interpreted execution there is an interdependence between the interpreter's execution and the interpreted application's execution; the implementation of the interpreter determines how the application is executed, and the application triggers certain activities in the interpreter. We present a representational model for describing performance data from an interpreted execution that explici...

The continuous transformation of the US military into an integrated and a dominant “full spectrum” capability requires a comprehensive and evolutionary system model (the objective) and a prescribed set of transformation processes (the means) whose incremental results are measurable against operational requirements. Given its sheer size and complexity, this military system must be partitioned in...

Today many system benchmarks use throughput as a measure of performance. While throughput is appropriate for benchmarking server environments, response time is a better metric for evaluating desktop performance. Currently, there is a lack of good tools to measure interactive performance; although several commercial GUI testing tools exist, they are not designed for performance measurement. This...
