Abstract: Both scholars and practitioners extensively acknowledge the importance of innovation in an economic environment that is characterized by rapid technological changes, compression of product and process life cycles, a surge in competition and the succession of economic booms and busts. Recent development of the innovation literature clearly indicates that there are many tensions, paradoxes and dilemmas associated with innovation activities. The studies published on the theme also demonstrate that understanding, managing and resolving these tensions are key points for realizing successful innovation and ensuring firms’ survival.
How tensions get reconciled is therefore attracting increasing interest in the research community which has introduced the concept of ambidexterity to describe the capability of firms to achieve and manage conflicting activities by realizing high levels of both in a simultaneous way.
Although ambidexterity is a relatively young theme, today it has become a central concept in management research, receiving contributions from various literature research streams. The recent expansion of the theme, with many papers published in the last two years, has produced a great number of contributions which call for a synthesis of recent results and development. This dissertation thus opens with a systematic review of existing studies on ambidexterity by using also “bibliometric analysis” techniques. This analysis allowed us to map and summarize the results achieved on the issue and to highlight some important methodological and theoretical gaps: we would like to address some of them in this dissertation.
The literature analysis showed first that most existing empirical studies have focused on the one hand on demonstrating the positive effects of ambidexterity and on the other on identifying the enabling factors of such a capability. How firms can develop, nurture and sustain ambidexterity capability, however, still remains a major point of discussion and the need for additional conceptual and empirical investigations about this issue persists.
Second, existing studies on ambidexterity, have identified three main solutions for resolving tensions: the structural separation of units for dealing with tensions (structural solution), the creation of a context where employees are encouraged to perform contradictory tasks at the same time (contextual solution) and the critical role played by managers in sustaining and guiding ambidexterity. The literature review however outlines that researchers have mainly focused attention on one single solution while there are no works that consider the possibility that these solutions are complementary and can coexist in the same organization.
Finally, organizations are recognized as being in continuous interaction with their competitive environment, and they co-evolve with it by reconfiguring their activities and design to meet environmental changes. It therefore appears unlikely that one single design would provide the exhaustive functionality required to deal with the entire range of boundary conditions and new tensions that an organization faces over time. However, there are no studies that take a temporally sensitive perspective, capturing ambidexterity's co-evolution with the organization’s environment.
Based on these considerations, the need for further studies aimed at analyzing how companies can achieve ambidexterity and how ambidexterity co-evolves with the competitive environment clearly emerges.
To better reveal the complexity of the phenomenon, the use of a more fine-grained unit of analysis is strongly recommended: using a granular level of analysis (as opposed to what has been done in empirical studies which adopt the firm or the business unit as the level of analysis) makes it possible to really answer the "how" question of such a complex phenomenon. Shifting the focus from the organization level to a more fine-grained level – such as a single organizational process, project or phase - can also open up interesting areas of research by allowing a more detailed picture to be depicted of the dynamics and mechanisms that lie at the basis of the development of ambidexterity capability. However, studies that examine ambidexterity at a micro level are relatively scarce.
Following these suggestions, we therefore decided to analyse ambidexterity capability in the “search phase” of the innovation process (early phase). This phase is in fact characterized by the tension between searching for knowledge that deepens and improves firms’ existing core knowledge (Local Search) and simultaneously searching for completely new and unfamiliar knowledge that expands the existing knowledge base of the firm (Distant Search). How firms can deal with this tension, and therefore succeed in building ambidexterity capability in the search phase, is therefore the focus of this dissertation.
Consistent with the definition of capabilities as “constituted in the everyday practices”, we have additionally decided to focus the attention on the analysis of the practices through which firms search for knowledge. Adopting a practices-based perspective represents in fact a worthwhile tool that allows us to obtain a closer understanding of complex and multifaceted phenomena such as ambidexterity capability.
Therefore our research questions are:
1. Are there any differences, in terms of search practices, between firms that show ambidexterity capability in the search phase of the innovation process and firms that do not show such a capability? What are these differences?
2. How can firms succeed in realizing ambidexterity capability in the search phase?
3. How does the achievement of ambidexterity capability change while co-evolving with the external environment?
In order to answer these research questions we followed a combined research approach. Given the different forms of the research questions (the first research question is a “What” form of question, while research questions two and three are a “How” form of question), two different methodologies are in fact used. The research approach of this dissertation can thus be broadly divided into two parts: a first part which aims to answer the first research question through a survey methodology where search practices (practices used to carry out the search for knowledge) are treated as a “black-box” and a second part that answers research questions two and three by adopting a case study methodology where the internal structure of search practices is examined.
To answer the first question we created a questionnaire designed to investigate the use of a set of practices for searching for knowledge with a double purpose: to generate knowledge in order to improve the knowledge base already present in the firm - "Local search "- or create completely new knowledge and expand the existing knowledge base of the company - "Distant search". The questionnaire also includes scales designed to measure the ambidexterity capability during the search phase. The questionnaire, which has been sent to a sample of Italian medium-high tech companies, allowed us to obtain a picture of the use of different practices for the generation of both local and distant knowledge. Through an exploratory factor analysis we have additionally identified reliable, valid and one-dimensional measures of search, linked to its two dimensions: "local search" and "distant search". The analysis conducted on the data, cluster analysis and comparison of clusters have also allowed us to verify that indeed there are differences between ambidextrous and non-ambidextrous firms in the search phase, and to identify the distinctive characteristics of those firms that have developed this capability, thus answering the first research question.
To answer the second and third research questions we have instead adopted a qualitative methodological approach. The qualitative research has involved one high-tech Italian firm, with the purpose of delving into how tensions that arise during the search phase of innovation process are managed and resolved. The case study has been conducted by adopting a longitudinal approach, through numerous interviews aimed at grasping the changes that have affected the search activities and the consequent achievement of ambidexterity. The case study has contributed to the literature on ambidexterity capability in two main ways. On the one hand it has enabled us to identify a potential three-phased process followed by the firm in achieving ambidexterity. On the other, the case study has clearly shown that there is no one single ambidextrous configuration that makes it possible to support all the environmental conditions that the organization must deal with over time. In other words, the organizational solution adopted to achieve ambidexterity changes over time, also depending on some features of the external environment.
