MODEL-BASED VALIDATION AND VERIFICATION OF ANOMALIES IN LEGISLATION

An anomaly in legislation is absence of completeness, consistency and other desirable properties, caused by different semantic, syntactic or pragmatic reasons. In general, the detection of anomalies in legislation comprises validation and verification. The basic idea of research, as presented in this paper, is modelling legislation by capturing domain knowledge of legislation and specifying it in a generic way by using commonly agreed and understandable modelling concepts of the Unified Modelling Language (UML). Models of legislation enable to understand the system better, support the detection of anomalies and help to improve the quality of legislation by validation and verification. By implementing model-based approach, the object of validation and verification moves from legislation to its model. The business domain of legislation has two distinct aspects: a structural or static aspect (functionality, business data etc.), and a behavioural or dynamic part (states, transitions, activities, sequences etc.). Because anomalism can occur on two different levels, on the level of a model, or on the level of legislation itself, a framework for validation and verification of legal regulation and its model is discussed. The presented framework includes some significant types of semantic and syntactic anomalies. Some ideas for assessment of pragmatic anomalies of models were found in the field of software quality metrics. Thus pragmatic features and attributes can be determined that could be relevant for evaluation purposes of models. Based on analogue standards for the evaluation of software, a qualitative and quantitative scale can be applied to determine the value of some feature for a specific model

PROACTIVE APPROACH TO THE INCIDENT AND PROBLEM MANAGEMENT IN COMMUNICATION NETWORKS

Proactive approach to communication network maintenance has the capability of enhancing the integrity and reliability of communication networks, as well as of reducing maintenance costs and overall number of incidents. This paper presents approaches to problem and incident prevention with the help of root-cause analysis, aligning that with the goal to foresee software performance. Implementation of proactive approach requires recognition of enterprise\u27s current level of maintenance better insights into available approaches and tools, as well as their comparison, interoperability, integration and further development. The approach we are proposing and elaborating in this paper lies on the construction of a metamodel of the problem management of information technology, particularly the proactive problem management. The metamodel is derived from the original ITIL specification and presented in an object-oriented fashion by using structure (class) diagrams conform to UML notation. Based on current research, appropriate metrics based on the concept of Key Performance Indicators is suggested

Business Model Enriched With User Experience, as a Systemic Tool in Service Design

Service design and business model design are considered in the literature as separate approaches to value creation for the customer. User experience, as a concept that represents a holistic emotional and meaningful result of the interaction with information technologies, is nowadays an important ingredient of the customer value. This paper aims to theoretically set the ground for using the business model concept as a systemic tool in service design that will support the design for user experience. Against this background, we ask: Can the business model concept successfully represent a system that is required for the value proposition-based service exchange? We investigate this question based on service-dominant logic and accompanying service science, and semantically compare elements of the service system, service ecosystem, and ten service science basic concepts. The analysis shows that the business model canvas, the chosen model for business model representation, satisfies the systemic perspective and can serve as a system platform for integrating with service design

A Case Study of Software Product Line for Business Applications Changeability Prediction

The changeability, a sub-characteristic of maintainability, refers to the level of effort which is required to do modifications to a software product line (SPL) application component. Assuming dependencies between SPL application components and reference architecture implementation (a platform), this paper empirically investigates the relationship between 7 design metrics and changeability of 46 server components of a product line for business applications. In addition, we investigated the usefulness of Platform Responsibility (PR) metric as an indicator of product line component changeability. The results show that most of the design metrics are strongly related to the changeability of server component and also indicate statistically significant correlation between Maintainability Index (MI) and PR metric. The assessment is based on a case study of the implementation of the product line for business applications in a financial institution. The results show that PR metric can be used as good predictor of changeability in the software product line environment

Factors of Risk Reduction in Agile and Lean Enabled Governance of IT Project Portfolios

The subject of this paper is project portfolio governance and its improvement based on agile and framework which improves the management of project portfolio processes’ execution and reduces the risks of portfolio components’ implementation. The existing project portfolio models and governance processes use traditional principles, regulation, planning, and control methods, which require enhancement to ensure the portfolio management processes are followed in successful project implementation. The agile and lean project portfolio governance is a relative new domain for which the awareness and practical results related to influence on governance processes, risks, and quality are missing. The contribution is foremost methodological in introduction of agile and lean portfolio governance methods and processes, followed by the agile and lean governance framework, and conclusively in revealing the factors of risk reduction in the agile and lean enabled project portfolio governance with the emphasis on implementation risks reduction

Business Model Grounds and Links: Towards Enterprise Architecture Perspective

The business model concept emerged in theory and practice without a consensus on the understanding of the concept, but it has become a well accepted and useful construct in fields such as strategy, organization, information systems and technology. This paper aims to provide an overview of the research on the use of business models focusing on outstanding works in this field, extracting main converging findings unburdened of extant lists of specific citations. Following the overview, a comparison of the seven respective conceptual frameworks of the business model research is presented. Finally, after determining grounds, the business model concept is linked to related complex concept – enterprise architecture

Automatizacija uredskog rada kao oblik racionalizacije u proizvodnji

Iako je tehnološki razvoj značajno utjecao na proizvodnost u proizvodnji, uredski su poslovi ostali manje-više isti (osobito u nas) sve do nedavna. No, ne može se poreći činjenica da je automatizacija posljednjih desetljeća zahvatila i ured. U suvremenom uredu danas se mogu zateći: terminali vezani za neko veliko računalo, samostalna mikroračunala (kao snažne radne stanice), specijalizirani procesori teksta, različiti štampači i crtači, modemi i druga telekomunikacijska oprema, te tradicionalna uredska oprema (telefoni, diktafoni, pisaći strojevi, fotokopirni aparati i dr.) Suštinske i nagle promjene u uredu prouzrokovao je kompjutor. U radu je prikazan jedan od temeljnih razvojnih koncepata suvremenih proizvodnih poduzeća. To je zapravo kompjutorski integrirano poslovanje, te njegova dva dijela: 1 . kompjutorski integrirana proizvodnja i 2. kompjutorski integrirane funkcije podrške. Unutar kompjutorski integrirane proizvodnje razmatraju se integracijske komponente i komponenta automatizacije uredskog rada. Pri tom se ured ne shvaća toliko kao mjesto u smislu prostora tj. lokacije, koliko kao središte zajedničkih događanja, aktivnosti. Automatizacija uredskog rada predstavlja oblik racionalizacije u proizvodnji
