Despite recent attention to self-adaptive systems (e.g., several ICSE workshops), development and analysis methods for such systems do not yet provide su?cient explicit focus on the control loops and their associated properties that almost inevitably control self-adaptation.

Accordingly, we define four quality dimensions and determine the corresponding measurable properties in the target system. We capture each dimension as a discrete set of values (for example, we use an ordinal scale of 1 to 5 to express the degree of disruption). We then elicit from the service providers the utility values and preferences for these dimensions, summarized in Table 1.
