Fifteen years ago software was primarily developed either within an organizational field of voluntary open source software communities or within an organizational field of commercial companies. Within the organizational field of open source software, participants looked upon themselves as programmers and users modifying and sharing codes, making them available to everyone for free. Within the field of commercial companies, managers and employees perceived software as a commodity that could be bought and sold, and the development of the software was wrapped in copyrights and licenses. Today, commercial companies are involved in activities within open source software communities in many different ways. How did people start to co-operate with the enemy on software development is the leading question in the book. The answers are based on in-depth studies of three empirical cases showing different variations of successful co-operation. In all three cases the development has raised serious identity questions like: Who am I? Who are my friends and enemies? And what is the right thing for me to do in the future? The book is for everyone interested in software development and/or open innovation processes and will be of particular interest for organizational scholars as it draws heavily on sociological concepts like institutional logics, institutional work and institutional actors.

In Sustainable Governance in Hybrid Organizations the author Linne Marie Lauesen explores how businesses that have succeeded in conducting sustainable governance, manage and govern their sustainable performance: in other words, how they manage to be economically, socially, and environmentally sustainable. In this respect, hybrid organizations that are formed as businesses with a mission to be sustainable and to provide services for society - such as water companies - are a good point of departure. Water companies are highly regulated whilst working primarily for the betterment of society and on behalf of generations to come, for whom clean and plentiful water and the preservation of nature is a must. Linne Marie has dug deep into these types of hybrid organizations in order to reveal which mechanisms of organizational governance for sustainability are at play, and how these organizations manage to balance their triple bottom lines in order to survive financially, socially, and environmentally and make a business out of their conduct. Balancing these three bottom lines in a sustainable way is explained in a clear and accessible way and the juxtaposition between non-profit and for-profit water companies will show how this model can be transferred to other business spheres.

Institutional theory has become one of the dominant organizational approaches in recent decades. Its roots can be traced to Europe, and an important intellectual objective of this book is to examine North American theory strands and reconnect them with European research traditions. In addition, this book focuses on how organizations and individuals handle heterogeneous and challenging social conditions which are subsequently reflected in various forms of change.

The Institutional Logics Perspective is one of the fastest growing new theoretical areas in organization studies (Thornton, Ocasio & Lounsbury, 2012). Building on early efforts by Friedland & Alford (1991) to "bring society back in" to the study of organizational dynamics, this new scholarly domain has revived institutional analysis by embracing a
