Procedural guidelines for the design method.

Non-Functional Requirements Procedural GuidelineFunctional Requirements

UniversalityIdentification of necessary partial models and their description in the style of working situations within a reference conceptFR5-Integration and consideration of context information in respect to the work context in intelligent production environments

Applicability, Inferability, UniversalityInclusion of a partial model, which incorporates potential design recommendations and interrelates these to remaining contextual elementsFR1-Qualitative and quantitative design recommendations on a more comprehensive level or quantitative design recommendations

Applicability and AnalysabilityEasy set-up and handling of partial models as well as their visual presentationFR5-Integration and consideration of context information in respect to the work context in intelligent production environments
FR3-Good presentation and visualisation of design recommendations as well as visualisation and communication of user scenarios

Inferability and AdaptabilityIntegration of a mechanism for the configuration of context elements supported by a modelling toolFR5-Integration and consideration of context information in respect to the work context in intelligent production environments

Analysability and InferabilityRealisation of a well-defined rule framework between partial models as well as the selection and implementation of an appropriate analytical technique for validating the consistency of logical rulesFR6-Focus upon physically unimpaired users in mobile working situations
FR2-Considerations of interactive products with multimodal interaction possibilities; Consideration of physical user interfaces, supporting the selection and configuration of appropriate mobile interaction devices
FR3-Good presentation and visualisation of design recommendations as well as visualisation and communication of user scenarios

InferabilityDescription of the context model in a semantic language in order to infer new knowledge based on existing knowledge (open world assumption). The interpretation and assessment of rules have to be ensured in order to infer new knowledge.FR2-Considerations of interactive products with multimodal interaction possibilities; Consideration of physical user interfaces, supporting the selection and configuration of appropriate mobile interaction devices
