Konferensbidrag (refereegranskat)abstract
- A gap in the alignment of business and IT lies between strategy and IS, despite the advancements of enterprise modeling. The objective of our study is to compare various enterprise modeling approaches with respect to their ability to capture and represent strategy notions. This includes identifying strategy notions from established business strategy formulations within Strategic Management, which are expressed in the Unified Business Strategy Meta Model. The interdisciplinary nature of the study constitutes a research challenge due to the significant difference on the levels of abstraction between Strategic Management and IS. To the best of our knowledge, no similar effort has been undertaken, therefore, the outcome of this study will provide the enterprise modeling community with a basis to address strategy and IS alignment linking strategic objectives and intentions to information systems.

Konferensbidrag (refereegranskat)abstract
- An important topic in the modeling for IS development concerns quality of obtained models, especially when these models are to be used in global scopes, or as references. So far, a number of model quality frameworks have been established to assess relevant criteria such as completeness, clarity, modularity, or generality. In this study we take a look at how a research process contributes to the characteristics of a model produced during that process. For example: what should be observed; what research methods should be selected and how should they be applied; what kind of results should be expected; how they should be evaluated, etc. We report a result on this concern by presenting how we applied Design Science Research to model business strategy.

Capturing Consumer Preference in System Requirements Through Business Strategy
- 2013

Tidskriftsartikel (refereegranskat)abstract
- A core concern within Business-IT alignment is coordinating strategic initiatives and plans with Information Systems (IS). Substantial work has been done on linking strategy to requirements for IS development, but it has usually been focused on the core value exchanges offered by the business, and thus overlooking other aspects that influence the implementation of strategy. One of these, consumer preferences, has been proven to influence the successful provisioning of the business's customer value proposition, and this study aims to establish a conceptual link between both strategy and consumer preferences to system requirements. The core contention is that reflecting consumer preferences through business strategy in system requirements allows for the development of aligned systems, and therefore systems that better support a consumer orientation. The contribution of this paper is an approach to establish such alignment, with this being accomplished through the proposal of a consumer preference meta-model mapped to a business strategy meta-model further linked to a system requirements technique. The validity of this proposal is demonstrated through a case study carried out within an institution of higher education in Sweden.

Exploring Risk-Awareness in istar models
- 2010
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The i* modeling technique focuses on an early-phase of requirements engineering aiming at understanding how a system would meet organizational goals, how it would fit within the organizational context, why would it be needed and why should it be preferred among other possible alternatives. Analysts are able to understand early the organizational context that bridges system requirements to organizational goals. However, it is not clear how uncertainty, potential threats and opportunities are taken into account both when developing a strategic dependency model and a strategic rationale model, to facilitate a continuous risk management. This paper proposes a set of guidelines for refining i* models based on risk

Linking Strategic Innovation to Requirements : a look into Blue Ocean Strategy
- 2012
-
Ingår i: Emerging Topics in the Practice of Enterprise Modeling.
-
Konferensbidrag (refereegranskat)abstract
- Business Strategy encapsulates an organisation's intentions towards the achievement of its vision. As such, business strategy frames the overarching business roadmap towards the accomplishment of strate- gic goals driven by competition, by own capabilities, or by innovation. Consequently, such a roadmap needs to be considered when building systems aimed at supporting the functionality of an enterprise. Intro- ducing business strategy to system's design using models facilitates the propagation of strategic notions to development techniques and methods. This study focuses on bringing a business strategy formulation driven by innovation into system requirements; specically, relating Blue Ocean Strategy to the notions of i*, an established goal modeling technique within requirements engineering.

Model-Centric Strategy-IT Alignment : An Empirical Study in Progress
- 2013
-

- IT pervades all sectors of today's organizations. To support efficient business solutions, business-IT alignment has been long-time discussed as a solution. Given the complexity of achieving alignment, in our research we have hypothesized the importance of one partial possible solution, namely, the fit between strategy and information system requirements. To systematically investigate the influence of widely-used business strategy formulations, such as Porter’s Value Chain, Kaplan & Norton’s Strategy Maps, and others, we propose a model-centric approach to strategy-IT alignment where the strategy formulations are represented in the form of models, and mapped to requirements models. The objective of this paper is to present a pilot empirical investigation assessing if strategy-IT alignment is an issue of concern, and seeking to obtain insights from practitioners about relevance of our modelbased view for strategy-IT alignment. The empirical information is collected through a well-prepared questionnaire-based survey.

Model-driven Alignment : Linking Business Strategy with Information Systems
- 2014
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Information technology (IT) is more pervasive than ever before, constituting a significant factor for performance and survival in the business arena. It is essential that IT within organizations understands what the Business needs in order to provide the necessary support and bring value, which is also true when IT is also the main value creator. Therefore, alignment between the Business and IT within organizations is an issue of great concern and it is still open for solvency both for business and IT executives and practitioners.This work is scoped to the alignment linkage between business strategy and information systems (IS), where business strategy typically constitutes the primary exponent of the Business and IS typically encapsulates the elements of IT sustaining an organization. Current approaches are either focused on detailed aspects of IS and treat business strategy abstractly or use distinct business strategy formulations (e.g. Value Chain) but deal with IS only partially. This is problematic because the abstract use of business strategy hinders traceability of strategic intentions and initiatives towards features/aspects of IS, which are aimed to actualize and support such intentions. Because approaches using distinct business strategy formulations are not relevant to all organizations and are limited only to the IS aspects addressed.Introducing a model-driven approach for the alignment linkage is aimed at addressing the outlined shortcomings. Following a design science research paradigm, the main artifact developed is the Unified Business Strategy Meta-Model (UBSMM), which is based on conceptualizing established business strategy formulations (e.g. Value Chain) and integrating them. UBSMM supports mappings to IS models used in organizations, such as IS requirements, enterprise models and enterprise architecture, and provides unambiguous utilization of business strategy for the alignment linkage.Contributions of this thesis are grounded both on the process of building UBSMM and mapping to IS models, as well as the artifact itself. Conceptualizing and integrating business strategy formulations provides a less ambiguous and unified view of strategic concepts. This limits variations in interpretation and reinforces mappings to IS models, which are defined based on inter-schema properties across models. Therefore, UBSMM can link business strategy to IS models enhancing their communication in a traceable manner, ergo, support alignment.

Konferensbidrag (refereegranskat)abstract
- Current advancements in the business arena necessitate more than ever before the alignment of The Business and IT in organizations, which has been acknowledged as a complex issue to address. Our research is aimed at systematically addressing the linkage between business strategy and information systems (IS). We propose a model-driven approach for alignment, by leveraging the influence of established business strategy formulations from Strategic Management, and model-driven principles used within IS. The objective of this paper is to present the results of an empirical investigation carried out in Sweden on the linkage seeking to obtain insights from practitioners about the relevance of the problem, as well as of our model-driven proposal to address it.
