The purpose of this book is to investigate the innovative process in engineering of consulting firms as a knowledge-intensive service sector. Extant literature in a resource-based view of the firm calls for empirical studies to illustrate the process of how human resource systems provide organisations with a competitive advantage. The key issue is on how the different elements of human resource systems interact. The evidence unveiled in this book does just that. Likewise, it has been suggested that resource systems as a source of a competitive edge should not be viewed as a static phenomenon. Sustained competitiveness requires an organisation to constantly adjust itself according to the evolving market conditions. Such dynamic capability has been illustrated in cases within this book. On the other hand, literature on innovative studies indicates that new analytical approaches applicable to both manufacturing and service industries can be beneficial to future research in this field. The tactic adopted in this book can serve as a prelude to such an attempt.
