Contextual Components of an Enterprise Architecture Framework for Pan-European eGovernment Services

Enterprise Architecture (EA) frameworks provide a wide range of architecture components. Contextual EA components provide the necessary guidance to design specific architectures in a given context e.g. for Pan-European Government Services (PEGS). Contextual EA components help to describe the background and scope of architecture work and provide a ground to tackle architecture challenges in an agreed way. The main contribution of this conceptual paper is to connect existing theoretical models as a basis to examine contextual components of an EA framework for PEGS. Three aspects are elaborated using a model-based approach: a Critical Success Factor Model, a Strategy Management Model and a Stakeholder Engagement Model. The identified models are aligned with EA standards and provide guidance to empirical research and to programs, projects and initiatives that wish to create interoperability architectures

Designing Informal EAM Interventions – A Complementary Approach for Managing Enterprise Architecture Complexity

Although Enterprise Architecture Management (EAM) is a mature discipline and widely adopted in practice, surveys indicate effectivity barriers that, at least partially, appear to be a consequence of local decision makers’ non-compliance with enterprise-wide architectural guidelines. Several recent contributions aim at extending the portfolio of EAM interventions by applying informal control mechanisms. Although promising to extend EAM effectivity, informal interventions are apparently not much utilized in EAM practice. Based on the assumption that a comprehensive presentation of design knowledge for informal EAM interventions would support more widespread adoption, this paper integrates existing knowledge components to a coherent design approach. The proposal covers theoretical justification, conceptual foundations, a taxonomy of generic informal interventions, a catalogue of derived EAM intervention types, and a process to systematically instantiate and evaluate situation-specific informal interventions. Two Action Design Research projects in large companies are summarized as evaluative evidence for the potential that comprehensive informal intervention design has for improving EAM effectivity

Chemical enterprise model and decision-making framework for sustainable chemical product design

The chemical product substitution process is undertaken by chemical industries for complying with regulations, like REACH in Europe. Initially devoted to chemists, chemicals substitution is nowadays a complex process involving corporate, business and engineering stakeholders across the chemical enterprise for orienting the search toward a sustainable solution. We formalize a decision making process framework dedicated to the sustainable chemical product design activity in an industrial context. The framework aims at improving the sharing of information and knowledge and at enabling a collaborative work across the chemical enterprise stakeholders at the strategic, tactical and operational levels. It is supported by information and communication technologies (ICT) and integrates a computer aided molecular design tool. During the initial intelligence phase, a systemic analysis of the needs and usages enables to define the product requirements. In the design phase, they are compiled with the help of a facilitator to generate the input file of a computer aided product design tool. This multiobjective tool is designed to find mixtures with molecular fragments issued from renewable raw materials, and is able to handle environment-health and safety related properties along with process physicochemical properties. The final choice phase discusses the solution relevancy and provides feedback, before launching the product manufacturing. The framework is illustrated by the search of a bio-sourced water–solvent mixture formulation for lithographic blanket wash used in printing industry. The sustainability of the solution is assessed by using the sustainability shades metho
