Over the past 20 years, governments in many countries around the world have sought to implement governance mechanisms to measure and assess the performance of public service organisations. As a consequence, public service organisations, especially those considered as poorly-performing organisations, have been subjected to unprecedented pressure to improve their performance and sustain performance improvement as a continuous process. However, efforts of public managers to improve the performance of their organisations have been undertaken without “comprehensive theories and rigorous evidence on this issue” (Boyne, 2006: 366). This thesis takes up the challenge of providing robust evidence on the factors associated with the performance improvement of public organisations. We propose that the notion of organisational capabilities offers a promising way to meet this challenge. From this standpoint, this research sought to identify the organisational capabilities whose development and use explain a public service organisation’s ability to improve its performance and sustain good performance in the long run. The empirical analysis was conducted in a population of hospital trusts in England. We firstly applied longitudinal and comparative case studies method into two acute hospitals trusts: one case of a successful performance improvement and one case of less-successful performance improvement. The purpose was to examine how the development (or lack of) a set of capabilities over time accounted for the differences in the performance outcome and trajectory of the two cases. Our findings identified the following capabilities as advantageous for achieving a sustained performance: collective leadership; action-oriented culture; effective clinical-managerial relationship; supportive external context; performance / finance control capability; coordination capability of the key delivery process; sensing capability and learning capability. We then employed quantitative method over the population of acute hospital trusts in England to explore the relationship between complementarities of capabilities and performance. The results demonstrated that only when in combination does the presence of the capabilities yield positive and significant association with performance. In other words, the presence of the whole system of the capabilities increases the trusts’ performance, while partial presence of a set of capabilities is either not significantly associated with, or even detrimental to, the trusts’ performance.

This dissertation examines the development and renewal of capabilities through acquisitions by drawing from absorptive capacity literature (Cohen and Levinthal, 1990; Zahra and George, 2002). This dissertation examines four interrelated questions concerning (1) the impact of acquisition experience on a firm’s absorptive capacity, (2) the role of absorptive capacity in the renewal of capabilities through acquisition, (3) the impact of capabilities renewal through acquisition on a firm’s choice of future growth mode, and (4) the impact of capabilities renewal through acquisition on post-acquisition performance. These questions are examined using FDIC data and surveys administered to top managers of banks that conducted acquisitions between October 2004 and October 2006. Results of this study suggest that a firm’s past experience with internal development and acquisition impacts the development of its absorptive capacity. Furthermore, results suggest that absorptive capacity has multiple dimensions and that the respective absorptive capacity dimensions have unique independent and joint effects on a firm’s ability to renew its capabilities through acquisition. Results also suggest that the impact of the change in capabilities on the firm’s choice of future growth mechanism largely depends on the nature of capability that changed through acquisition. When firms experience an improvement or decline in important revenue-generating capabilities that are fundamental to firm performance, the firm is more likely to pursue future acquisition to either compensate for its inability to grow by its own internal means or to exploit its improved capability in a new setting. However, when management capabilities or operational capabilities experience an improvement or a decline, the firms is less likely to pursue future acquisition in order to avoid taxing the already strained capability or to take time to fully internalize the improved capability. Results also suggest that the change in capabilities through acquisition is positively associated with a change in post-acquisition performance.
