The contribution of small firms towards the creation of economic value in a country’s Gross Domestic Product, employment and innovation is widely acknowledged. Relatively little is known on how small firms are adopting IT strategically to acheive business-IT alignment and how alignment changes over time. This study examines from a dynamic perspective IT adoption actions undertaken by owner-managers, in relation to business-IT alignment in small firms in the island state of Malta. To attain its research objectives, the methodological stance adopted in this research study is that of grounded theory. Moving away from a deductive approach, this study embraces a constructivist approach using a combination of inductive and abductive thought. No fewer than thirty-one in-depth interviews are conducted with owner-managers to observe alignment patterns of IT adoption behaviour in their respective small firms operating in Malta and employing up to 49 employees. Four business-IT alignment equilibrium states are identified, serving as markers to map out the common IT alignment paths that each firm pursued, not necessarily in linear form, during their operational years. A substantive model, which identifies four distinct IT alignment patterns, denotes each common path that a group of firms took in their movement from one alignment equilibrium state to another, throughout their life-cycle stages. This study has substantive application and comprises several implications for the development of IT adoption behaviour when small firms endeavour to strategically align business with IT. It provides policy-makers, academic researchers and small firms’ owner-managers with a theoretical framework that can provide them with factors that can predict the kind of alignment patterns that are likely to occur. Findings indicate that the quality of IT related technological solutions that are taken up by each small firm are reliant on the owner-manager’s characteristics that focus mainly on the knowledge of internal IT expertise and the project management capabilities to manage IT outsourcers. Given that few studies have been conducted to study and establish patterns of IT alignment in small firms, this research provides an important contribution to knowledge and to the existing academic literature.

To survive and succeed in the very competitive business environment, firms should have a clear business strategy supported by appropriate information technology (IT) and marketing strategies. Whilst many prior studies argue that strategic alignment between, for example, business strategy and IT strategy generally enhances organisational performance, strategic alignment including multiple factors has received little attention and strategic orientation of firms is rarely considered. This research, drawing on configurational theory and strategic management literature, aims to understand the performance impact of triadic strategic alignment between business, IT, and marketing strategies based on strategic orientation of firms. A number of hypotheses are proposed to examine the relationship between triadic strategic alignment and organisational performance through the use of structural equation modelling, and to identify generic types of triadic strategic alignment. The hypotheses are tested through MANOVA using data collected in a questionnaire survey of 242 managers in Yemen. The findings indicate that (1) there is an ideal triadic strategic alignment for prospectors and defenders; (2) triadic strategic alignment has a positive impact on organisational performance; and (3) triadic strategic alignment provides a better indication of the nature and performance impact of strategic alignment. Follow-up interviews were also conducted to support the arguments and to clarify how strategies should be aligned. This research also contributes to managers’ knowledge and understanding by suggesting how a firm should coherently align its strategies to improve organisational performance.

Enterprise Architecture is so far the highest development step in IT's architectural description of enterprises. At the beginning, just technological architecture existed. However, with the quickly growing complexity of IT other domains occurred, that had to be described. Information or application architectures can serve as examples. IT then realized, that it needed to add to its IT architectures a business view and consequently the discipline Enterprise Architecture came into being. Strategic management is crucial for the development of each enterprise. The thesis focuses on the strategic management of business and the strategic management of IT. The strategic management of business consists of a business strategy and an operating model. To the strategic management of IT then belongs an information strategy and IT governance. Business-IT alignment further explores and ensures the accord between the strategic management of business and the strategic management of IT. The aim of the thesis is to describe the relationship of Enterprise Architecture and the different forms of strategic management and to express to which rate Enterprise Architecture supports them. The explored relationships are: - The relationship of Enterprise Architecture and business strategy - The relationship of Enterprise Architecture and operating models - The relationship of Enterprise Architecture and information strategy - The relationship of Enterprise Architecture and IT governance - The relationship of Enterprise Architecture and business-IT alignment The goals of the thesis are reached via theoretical research and subsequent deduction. The author's personal asset consists of creating a hierarchical model of Enterprise Architecture, of defining Enterprise Architecture's reaction to business strategies, of modifying the methodology MMDIS in respect of information strategy, of depicting, how Enterprise Architecture can be used in IT governance, of illustrating, where Enterprise Architecture contributes to business-IT alignment and of assessing, to which rate Enterprise Architecture supports the different forms of strategic management.
