That research has focused primarily on the fit between business and IT strategies, while cross-domain alignment, i.e., alignment between business strategy and IT infrastructure components, has received far less attention. Further, previous studies have focused on the implications of alignment for firm performance while the effects of cross-domain alignment on business unit performance in multi-business organizations (MBOs) are yet to be examined. This issue is important as IT infrastructures are evolving rapidly. Specifically, MBOs are increasingly turning to corporate IT platforms to support a common set of shared IT needs, while still allowing individual business units to manage unique aspects of their own IT needs through local IT applications. Extending prior research, this study proposes that performance of business units in MBOs is influenced by two complementary forms of cross-domain alignment, viz., alignment between the corporate IT platform and the corporate business strategy, and alignment between the business unit’s portfolio of IT applications and its business strategy. Using data from a global survey of 120 organizations, we find evidence that complementarity between these two forms of cross-domain alignment creates a joint positive effect on business unit performance. We also find that this effect varies with the extent of process digitization within business units. Implications for theory and practice are discussed.</p></div>","PeriodicalId":50037,"journal":{"name":"Journal of Strategic Information Systems","volume":null,"pages":null},"PeriodicalIF":7.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.jsis.2020.101623","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129970799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our call for papers to this special issue invited original studies to go further and advance our thinking on the strategic implications of this layered evolution of workplace technologies on work and the structure of organisations. In this introduction, we synthesise the main themes from the special issue, and also ongoing dialogues with the growing community at the regular AIS / IFIP 9.1 workshop on the Changing Nature of Work. A key observation is that the work involved in <em>configuring</em> emergent Digital/Human configurations, is vastly under-reported and poorly understood. Paradoxically, this configuring work is the most demanding and critical in the shaping of modern organisations. We suggest that this type of largely invisible work requires engagement beyond the level of execution or even the meaning of work, it requires intervening with third order effects that get to the core of what an organisation is. We highlight the challenges for organisations in dealing with third order change, particularly because these effects are beyond existing frames of reference and require more dynamic and supple responses based on the values, purpose and<!--> <!-->intent dominant<!--> <!-->in the organisation – we describe this as <em>structural digital work</em>.

Whilst IT-enabled openness in strategy has received significant interest recently, few studies have focused on the specific (digital) work practices of strategists and subsequently connected this to notable outcomes such as organizational transformation.

Drawing on a human–machine configuration perspective, we found that humans and the algorithm were configured and reconfigured in multiple ways over time as the organization dealt with the introduction of algorithmic analysis. In contrast to replacing human work, the emergent configurations required new roles and redistribution of extant expertise to augment and improve the accuracy of the algorithm.

However, social media’s openness to outsider users poses significant challenges to maintaining alignment between social media logic (or platform logic that guides decisions and actions on the platform) and the dominant organizational logic. Through an in-depth, longitudinal, abductive study of three successive social media implementations in a single organization, I explore the process of maintaining (or losing) social media alignment and its long-term consequences on the nature of the work. The paper shows that digitalization exposes the work to continuous adjustment within and across three elements of digital work: digital infrastructure work (embracing new uses of the platform at the user level), digital strategy work (redesigning governance policies), and aligning work (fitting uses with the platform logic underlying digital work). The findings show that despite initial social media alignment, through continuous coevolution of these three elements, the platform logic underlying digital community work eventually drifted away from supporting the organization’s original logic of cohesion to supporting an alternative logic of inclusivity. Accordingly, a process model of platform drifting has been developed. By taking a closer look at actual practices, the paper contributes to digital work research by identifying distinct elements of digital work involved in social media (mis)alignment and illustrates the profound, long-term consequences of social media on the nature of the work.</p></div>","PeriodicalId":50037,"journal":{"name":"Journal of Strategic Information Systems","volume":null,"pages":null},"PeriodicalIF":7.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.jsis.2020.101615","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115262734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
