“…The control variables include organization size, experience, and top management support, which are control factors often included in studies examining the success of IS management [e.g., 4,14,49]. We also included a control for the extent to which organizations had problems with legacy systems, because legacy systems can be a significant impediment to systems integration [49,81,85]. We also controlled for the importance of each architecture objective, as not all organizations place equal emphasis on standardizing the management of IT resources across their business units.…”

Organizations increasingly need to build an enterprise-wide capability to leverage technology that is distributed in different business units. Some organizations establish enterprise architecture (EA) standards to enable greater compatibility of IT components and integration of applications and data across the enterprise. Through a firm-level survey, we sought to answer two key questions about the use of EA standards: (1) How do different governance mechanisms affect the use of EA standards? and ( 2) To what extent does the use of EA standards help organizations to improve the sharing and integration of IT resources across the enterprise? We identified four key governance mechanisms for EA standards management and examined how each mechanism affected the use of EA standards. We also examined how the use of EA standards affects the management of IT infrastructure, applications, and data resources across business units. Our empirical results showed that the use of EA standards is effective in helping organizations to better manage their IT resources. Our study also provides detailed insights into how organizations can set up governance mechanisms to facilitate the use of EA standards in achieving enterprise-wide goals.

“…Organisations struggle when they need to collect, consolidate and share fragments of data and information distributed and duplicated among many systems. The disparate information systems have a very negative impact on business efficiency and competitiveness (Singh, 1997).…”

Purpose -This paper seeks to investigate the role of information systems integration in Irish small and medium-sized enterprises operating in the manufacturing sector. Design/methodology/approach -Research was conducted through a review of literature and subsequent primary research involving qualitative (semi-structured interviews) and quantitative (questionnaires) research strategies. Findings -The paper reveals the sophistication of internal IT infrastructure within Irish manufacturing SMEs and whether the IT systems are integrated with one another, and, if so, how well that integration is done. Moreover, the owner-managers' and senior managers' attitude to IS integration issues is explored, including the reasons that prompt them to integrate IT systems within their businesses, their expectations of IS integration, the challenges they recognise when integrating the systems and their criteria regarding IS integration.Research limitations/implications -The research focuses on manufacturing SMEs operating in Ireland; other sectors are not investigated. Practical implications -The paper helps the owner-managers and senior managers to understand the issues of IS integration and points towards possible solutions to the problem of disparate IT systems. Originality/value -The negative impact of disparate systems and the benefits of integrating them in an SMEs environment have not been thoroughly examined to date.
