COMPARATIVE EVALUATION OF THE RULE BASED APPROACH TO REPRESENTATION OF ADAPTATION LOGICS

Due to the rapid growth of business processes digitalization, enterprise applications cover more and more business and daily life functions thus becoming more complex. Complex enterprise applications often deal with low users’ satisfaction of usability. This problem can be solved by implementing adaptation algorithms in enterprise applications, so they can be adjusted for specific context situations and specific users’ needs. Some adaptation logics representation techniques are complex and require specific knowledge and skills to manage and modify adaptation process. In this paper rule based adaptation approach is introduced where rules are used as means to manage and modify adaptation process. Rules are easy to read and understand, thereby rule based adaptation should ensure elastic, transparent and easy administrable adaptation process. The goal of this paper is to test this statement by carrying out a comparative adaptation logics representation evaluation experiment. During the experiment participants are required to complete tasks which include different forms of adaptation logics representation (code, rules and models). Experiment results are analyzed by qualitative and quantitative measures such as users’ understandability of applications behavior when adaptation case occurs and users’ satisfaction with adaptation logics representation. Experiment results are summarized and are to be used for further development of the study

RULE BASED ADAPTATION: LITERATURE REVIEW

Rule based adaptive systems are growing in popularity and rules have been considered as an effective and elastic way to adapt systems. A rule based approach allows transparent monitoring of performed adaptation actions and gives an important advantage of easily modifiable adaptation process. The goal of this paper is to summarize literature review on rule based adaptation systems. The emphasis is put on rule types, semantics used for defining rules and measurement of effectiveness and correctness of rule based adaptation systems. The literature review has been done following a systematic approach consisting of three steps: planning, reviewing and analysis. Targeted research questions have been used to guide the review process. The review results are to be used for conducting further research in the area of rule based context-aware adaptive systems. This paper accents the potential of using rules as means to perform adaptive actions in enterprise applications taking into account contextual factors as well as points challenges, difficulties and open issues for planning, developing, implementing and running of such systems

Capability Driven Development: An Approach to Designing Digital Enterprises

The need for organizations to operate in changing environments is addressed by proposing an approach that integrates organizational development with information system (IS) development taking into account changes in the application context of the solution. This is referred to as Capability Driven Development (CDD). A meta-model representing business and IS designs consisting of goals, key performance indicators, capabilities, context and capability delivery patterns, is being proposed. The use of the meta-model is validated in three industrial case studies as part of an ongoing collaboration project, whereas one case is presented in the paper. Issues related to the use of the CDD approach, namely, CDD methodology and tool support are also discussed

Towards a Model of Context-Aware Recommender System

Users often have difficulties to use large-scale information systems efficiently because of their complexity. Additionally, these systems might be context dependent. If these context dependencies are taken into account during the system’s run-time phase, the most appropriate functionality might be provided to users in the form of recommendations for each context situation. The paper proposes to account for the context dependencies by using context aware recommendations and outlines an approach for modeling such recommendations. This approach is based on methodological foundations of Capability Driven Development. The paper discusses a motivational case for developing context aware recommendations and presents the initial method for recommendation modelling

Capability-Driven Development of a SOA Platform: A Case Study

Capability-driven development (CDD) is a novel paradigm for organisational modelling and information technology development. Its cornerstones are capability modelling (including goals, context, processes), pattern-based design, and runtime context awareness and service delivery adjustment. There is a lack of empirical studies regarding the industrial application of CDD. This paper reports on a case study that focuses on capability modelling within a service-oriented architecture development project. We have collected lessons learned, as well as open challenges to feedback the improvement of the CDD methodology

Capability Modeling: Initial Experiences

Enterprises operate in dynamically changing environments, consequently, information systems (IS) are a subject to continuous changes. The IS need to be adjusted to different customers, markets and run-time contexts affecting their design and delivery. Variability and customization of the information systems has become a serious challenge. Capability Driven Development (CDD) has been proposed as a new approach for dealing with variability. CDD allows delivering enterprise capability in dynamically changing circumstances - contexts. To model enterprise capabilities, concepts defined in the Capability meta-model are used. This paper discusses initial Capability modeling experiences. The main emphasis is put on the Capability design phase of the CDD approach. Several empirical cases are included to share the Capability modeling experiences, to validate the Capability meta-model as well as to discuss the difficulties of Capability modeling, open issues and future wor
