From Organization Business Model to Information System: One Approach and Lessons Learned
2011
The system ISTechnology and lessons learned of its use in the business modeling and development of information systems are analyzed in the paper. The system consists of the meta-model and applications. The meta-model enables to define a platform independent business model of the organization. The applications provide the definition and interpretation of the business model. Interpretation of the business model provides functionality of the information system in the selected platform. The lessons learned confirm that the development and maintenance cost of information systems can be significantly reduced by use of the ISTechnology.
Managing information security in a business network of machinery maintenance services business – Enterprise architecture as a coordination tool
2007
Today, technologies enable easy access to information across organizational boundaries, also to systems of partners in business networks. This raises, however, several complex research questions on privacy, information security and trust. The study reported here provides motivation and a roadmap for approaching integrated security management solutions in a business network of partners with heterogeneous information and communication technologies (ICT): Systems, platforms, infrastructures as well as security policies. Enterprise architecture (EA) is proposed as a means for comprehensive and coordinated planning and management of corporate ICT and the security infrastructure. The EA approach …
An Architecture for Collaborative Scenarios Applying a Common BPMN-Repository
2005
Collaborative business scenarios require a flexible integration of enterprises. To manage inter-organizational business processes, existing concepts for business process management (BPM) need to be adopted and extended. This paper presents a conceptual architecture for cross-enterprise processes’ planning, implementation, and controlling. Core component of the architecture is a distributed repository managing all required data and information, which especially obtains a process-oriented view on collaboration networks. Cross-organizational processes need close coordination among networking partners. This is achieved through the integration of business process models. Thus we further propose …
Business models and opportunity creation: How IT entrepreneurs create and develop business models under uncertainty
2015
How can entrepreneurs develop business models for markets in which the technology is constantly changing-or create business models for markets that do not exist? These are fundamental questions for information technology IT entrepreneurs, and for information systems IS scholars who seek to develop a theoretical understanding of business models. The case study presented in this paper addressed these questions, demonstrating how a small software firm developed its business model over a 15-year period in cloud gaming markets. Based on the empirical findings, a preliminary theoretical model is presented. The aim of the model is to increase scholarly understanding of how business models are crea…
The Role of Business Models in Developing Business Networks
2008
Business models have received a substantial amount of interest recently. Also, various research studies have discussed business models, especially in the context of a single company operating in mass markets. Unfortunately, these models often are not applicable for complex products or services that build on long-term knowledge about customer tastes, facilities, and skills. Especially on global markets, the asset specificity and vast geographical distances make it difficult for any single company to provide this kind of service cost-efficiently on a large scale. Instead, it calls for cooperation among multiple firms. Creation of a joint business model for a collaborative network is a necessa…
The Quest for Underpinning Theory of Enterprise Architecture - General Systems Theory
2017
Enterprise architecture originates from the 1980’s. It emerged among ICT practitioners to solve complex problems related to information systems. Currently EA is also utilised to solve business problems, although the focus is still in ICT and its alignment with business. EA can be defined as a description of the current and future states of the enterprise, and as a change between these states to meet stakeholder’s goals. Despite its popularity and 30 years of age, the literature review conducted on top information and management science journals revealed that EA is still lacking the sound theoretical foundation. In this conceptual paper, we propose General Systems Theory (GST) for underpinni…
Systemic Management of Architectural Decisions in Enterprise Architecture Planning. Four Dimensions and Three Abstraction Levels
2006
This paper presents a process model for the management of architectural decisions in enterprise architecture planning. First, decisions are made at the enterprise level, with strategic business considerations on the enterprise information, systems and technology strategy and governance issues. The next step is to define the domains, to then go on with domain architecture decisions. At the systems level, the enterprise and domain architecture decisions are collected and converted into architecture descriptions accurate in precision, form and detail to be given as input to the information systems development process, following the architectural planning. The model is derived from previous wor…
Towards a Reference Architecture for Model-Driven Business Apps
2016
Model-driven development techniques have been proposed for cross-platform app development. Typically, an individual domain-specific language (DSL) is used. The MD² framework consists of a DSL for business apps and generators, which transform a domain model to native platform code. Prior research on it focused on language and general generator design, this paper accentuates the code generation stage. A reference architecture for the generated apps is proposed to accelerate the development of new generators for which architectural decisions had been made on ad-hoc basis up to now. Moreover, generators are going to expose similar structures that facilitate maintenance. Our proposal takes MD²'s…
Challenges of Government Enterprise Architecture Work – Stakeholders’ Views
2008
At present, a vast transformation within government systems is executed towards electronic government. In some countries, this change is initiated as enterprise architecture work. This paper introduces results from an empirical study on different stakeholders' views on enterprise architecture development within Finnish state government. The data is gathered from 21 interviews accomplished during spring 2007 among participants of the Interoperability Programme of Finnish state administration. The interviewees represent different sectors and levels of Finnish government and IT companies. On the basis of qualitative data analysis we discuss challenges of enterprise architecture work in the con…
