Performance Management Work

Excerpt

Performance is a key quality factor of application systems (AS). AS performance is quantified by the metrics response time, resource utilization, and throughput (Becker et al. 2013). To guarantee AS performance, it is important to define quantifiable performance goals using performance metrics. These metrics have to be continuously measured and evaluated. Based on these metrics, activities can be defined to ensure that performance goals are met. The coordination and execution of all activities required to achieve performance goals during system development are described by the term software performance engineering (SPE) (Woodside et al. 2007). Corresponding activities during operation are typically referred to as application performance management (APM) (Menascé 2002). An isolated consideration of SPE and APM neglects their interrelation. The combination of SPE and APM activities is therefore summarized by the term performance management work (PMW). PMW is becoming a growing challenge due to developments in the areas of AS architecture, IT governance, and system life cycle. …
