Performance Engineering

The performance of a system can be evaluated by comparing indicators based on actual measurement(s) or observation(s) of the system behavior to a predefined standard or norm. Performance is an umbrella term of concepts used for quantifying the efficiency and effectiveness of systems (including activities, processes and employees).

Efficiency in this context is the ratio between the actual resource usages of the system against the minimum; i.e., input versus output. Effectiveness measures the system’s ability to reach its objective. A number of performance indicators are used to evaluate the efficiency and effectiveness.  Indicators are constructed from actual measurement(s) or observation(s).  Indicators are commonly constructed from one or several measurement(s).  There are cases where measurement can be used as an indicator, directly without calculations.

Cost is the fundamental metric but many non-cost metrics are used.  Examples are manufacturing related metrics such as reliability, quality, speed and flexibility. Employee related metrics include reliability, knowledge, skills, thoroughness, attention to details, ability to produce consistently and effectively.

The research group is working on issues regarding to product development productivity.  The main focus is on the iterative design process; e.g. prototyping, testing, analyzing and refining until the design criteria are met.  The group works on developing methods for quantifying and optimizing the efficiency and effectiveness of the iterative process in order to increase productivity.
