Setting quality targets for coming releases with QUPER - an industrial case study

Summary, in English

Quality requirements play a critical role in

driving architectural design and are an important issue in

software development. Therefore, quality requirements

need to be considered, specified, and quantified early during

system analysis and not later in the development phase

in an ad-hoc fashion. This paper presents the quality performance

model that estimates quality targets in relation to

market expectations as a basis for the architecting of

quality requirements. The purpose of the model is to provide

concepts for qualitative reasoning of quality levels in

the decision-making of setting actual targets of quality

requirements for coming releases of the product. The

quality performance model is evaluated at one case company,

using a market-driven development approach, in the

electronic payment-processing domain. The results show

that the model is useful for supporting early decisionmaking

in, e.g., release planning of quality requirements
