Managing digital business platforms: A continued exercise in balancing renewal and refinement

Central to the evolution of a digital business platform is the organization’s ability to balance exploration (renewal) and exploitation (refinement) simultaneously. Drawing on prior research—including digital platforms, contradictory tensions, and organizational ambidexterity—and our own experience investigating digital business platforms in organizations, this article provides insights into how executives can manage this evolution successfully. More specifically, we present a framework recognizing three pairs of organizational capabilities (i.e., identifying-nourishing, expanding-legitimating, and augmenting-embedding) that enable balancing renewal and refinement of the platform over time. We close by providing critical managerial practices that executives can use in anticipating, adjusting, and evaluating the evolution of a digital business platform over time, including its initiation, development, and growth.     

Trading off learning and performance: Exploration and exploitation at work

Employees are increasingly given control over how they learn, and their choices for training are diverse and varied, yet employees must balance competing demands. On one hand, they are expected to be increasingly efficient in their current job duties – on the other hand, they are expected to develop new skills and competencies that enable them to adapt and respond to changing job demands. Drawing from the organizational learning literature, we propose a model of worker and work characteristics that inform choices between two mindsets related to learning at work. The first mindset is exploration, or the pursuit of learning outside one’s current knowledge domain; the second mindset is exploitation, the refinement/deepening of one’s existing knowledge stock focusing on the task at hand. We further propose that these strategic choices, or trade-offs, influence employee learning and performance in unique ways, with different implications for both routine and adaptive performance. Finally, we incorporate the notions of feedback loops and risk assessments that influence ongoing decisions between exploration and exploitation mindsets. Recommendations for future research and extensions of the theoretical model are also proposed.

The effect of external supply knowledge acquisition,development activities and organizational status on the supply performance of SMEs

Given the increasingly strategic role of external resources, acquiring knowledge about current suppliers and the broader supply market is an important and demanding task for the purchasing and supply management (PSM) function of a firm. Performance-improvement-oriented application of external supply knowledge present further challenges for the function. To examine this, we draw on the knowledge-based view and develop a hypothesized model in which supply knowledge acquisition drives PSM exploration and exploitation orientations which in turn mediate the organizational status of PSM function in terms of supply performance. We test the model on an SME-focused and survey-based dataset, using structural equation modelling. Our results indicate that an exploitative orientation is associated with knowledge gained from the supply base, whereas an explorative orientation is predominantly associated with supply market knowledge and less with supply base knowledge, suggesting natural pairings. The findings also show how an exploitative development orientation mediates the positive association of the PSM function's organizational status with supply performance. Driven by supply base knowledge, a status-empowered exploitative PSM orientation may suppress supply market based explorative orientation in resource-scarce SMEs, thus appearing to serve as the sole path to supply performance. Our research contributes by pointing out the significance of the knowledge-resource, and the knowledge-based view, in understanding performance in PSM.

Dynamic ambidexterity: How innovators manage exploration and exploitation

Firms must excel at both exploration and exploitation to ensure long-term survival and prosperity. However, firms often have difficulties in doing so because they have to accommodate the contradictory logics of exploration and exploitation. This article examines the logics of exploration and exploitation, evaluates the difficulties of accommodating both logics, and identifies dynamic ambidexterity as a new way to overcome these difficulties. To achieve dynamic ambidexterity, firms need to support structural ambidexterity at the corporate level, contextual ambidexterity at the business-unit level, and sequential ambidexterity at the project level. I believe that the notion of dynamic ambidexterity and its managerial practices can help firms manage exploration and exploitation and ensure long-term survival and prosperity.     

Exploratory and exploitative innovation: To what extent do the dimensions of individual level absorptive capacity contribute?

Individuals are considered the frontline that allows firms to learn from external sources. However, a firm can only benefit from individual efforts if it understands to what extent the dimensions of individual-level absorptive capacity are related to its innovation strategy. A firm's innovation strategy is characterized by the notions of exploration and exploitation, which result in either radical or incremental innovation. This study examines the driving factors of individual-level absorptive capacity regarding a firm's exploration versus exploitation strategy. Using quantitative data from 104 individuals, partial least squares structural equation modeling (PLS-SEM) analysis was conducted, verifying individuals' competencies in identifying external knowledge as a trigger for both exploratory and exploitative innovation. Consequently, these specific abilities also contribute to organizational ambidexterity. Furthermore, the results show the dichotomous contribution of individual competencies in assimilating external knowledge. While exploratory innovation thrives with individual assimilation efforts, realization of exploitative innovation is not significantly related to these efforts. Ultimately, individuals' competencies in utilizing external knowledge are significantly related to neither exploratory nor exploitative innovation. Moreover, this study provides means for managers to systematically position individuals in the external search process.     

Strategy–organization configurations in corporate venture units: Impact on performance and survival

We develop a typology of corporate venture units, based on their strategic role in the corporation, and specifically on (a) their relative emphasis on exploration versus exploitation and (b) the internal versus external locus of opportunity they pursue. Following configurations logic, we argue that the structures and systems used by venture units will be a function of their strategic role, and that their performance will be higher when internal elements are aligned. We also argue that exploitation-oriented units will survive for longer than exploration-oriented units. Using primary data collected on 95 venture units during 2001–2003, we use configurational analyses to test and find support for our hypotheses.     

The asymmetric moderating role of market orientation on the ambidexterity-firm performance relationship for prospectors and defenders

Drawing on the resource-based view of the firm and, in particular, the capabilities perspective of firm performance, the authors examine the relationship between ambidexterity and firm performance for two strategy typologies: prospectors and defenders. Ambidexterity, defined as the combination of two discrete capabilities (exploration and exploitation), should have a less negative effect on firm performance among prospectors that add exploitation to exploration than among defenders who add exploration to exploitation. Hence, this research predicts an asymmetric effect of ambidexterity on firm performance for prospectors and defenders. The authors further posit that a boundary-spanning culture, such as market orientation, can function as a metaculture by integrating the subunit cultures generated by exploration and exploitation. As a result, market orientation should mitigate the negative effect of ambidexterity on firm performance, albeit differently for prospectors and defenders, and thus point to an asymmetric moderating role of market orientation. The findings provide mixed results, which the authors discuss along with some theoretical and managerial implications.
