Flexibilitätspotenziale heben - IT-Wertbeitrag steigern: HMD Best Paper Award 2013 (essentials)
by André WiedenhoferIn den vergangenen Jahren nahm die Veränderungsgeschwindigkeit in den Unternehmen stetig zu. Die wachsende Globalisierung, die Auswirkungen der Krise und die rasch wandelnden Technologien haben bewährte Geschäftsmodelle grundlegend in Frage gestellt. Die ständige Anpassung wird ,,business as usual". Dadurch bedingt ändern sich die Anforderungen an die betriebliche Informationstechnologie (IT). Um einen wesentlichen Wertbeitrag zu generieren, muss die IT der marktinduzierten Unsicherheit mit einem angemessenen Grad an Flexibilität begegnen. In Anlehnung an die ressourcenorientierte Theorie stellt André Wiedenhofer die IT als wesentliche Kernkompetenz dar. Da Unsicherheit in der Literatur bisher kaum Beachtung gefunden hat und Flexibilitätspotenziale scheinbar noch nicht ausgeschöpft sind, soll der Beitrag Handlungsempfehlungen geben, wie die IT langfristig ihren Wertbeitrag organisatorisch verbessern kann.
Flexibility and Lifelong Learning: Policy, Discourse, Politics
by Katherine NicollWhat can the politics of discourse tell us about the discourse of politics? How are flexibility and lifelong learning positioned within policy? Flexibility and lifelong learning have become key aspects of education policy in nation states and bodies such as the European Union and Organisation of Economic Cooperation and Development in recent years. They are positioned as necessary for the knowledge economy and social inclusion. The failure to adapt through becoming more flexible and participating in lifelong learning is held up as a failure at individual, organisational and national levels. But how has that narrative come to be constructed? In what ways is it persuasive? And what forms of political action are possible and necessary? These are the questions addressed in this text. Drawing upon the work of Michel Foucault and on the notion of rhetoric, this book forensically explores examples of the work of policy texts in the discourses of education, lifelong learning and flexibility that they construct. In so doing, it argues for the need to take policy discourse seriously and not simply dismiss it as ‘spin’. Through a detailed examination of policy texts from primarily Australia, the UK and European Union, this text provides insights into the strategies through which flexibility and lifelong learning become realized and realizable as part of the common sense of educational discourse. Rather than simply rejecting these ideas, or suggesting they are merely the window dressing for the more malign interests of the knowledge economy or globalization, it suggests a politics of the wedge and possibilities for the insertion of different meanings. Central to the claims of this text are that we need to engage closely with the discursive and rhetorical strategies of policy, in order that we understand both how it is constructed and thus how it can be deconstructed.
Flexibility, Innovation, and Sustainable Business (Flexible Systems Management)
by Ramesh Anbanandam Santosh RangnekarThis book contains practical experiences, knowledge, and insights in the evolution, formulation, and implementation of strategies and models for flexibility, innovation, and sustainable business. The book discussed the increasing significance of a flexible approach by businesses as much as possible in every area of their work—from employment policies to supply chain management (SCM). It further links this flexible approach to a sustainability strategy, which is necessary to be competitive today and in the future. This business approach is necessary to create long-term value by considering how a given organization operates in the ecological, social, and economic environment. This is linked to the next theme of the book—innovation—which is fundamental for a business to improve its processes, develop new and improved products and services for the market, increase its efficiency, and, most importantly, get better profitability. The book also delves into another buzz word in business—analytics. Companies have widely embraced the use of analytics to streamline operations and improve processes. The book explores all these critical emerging areas through the chapters in its five sections and is invaluable for management students and researchers, practicing business managers, consultants, professional institutions, and government and corporate organizations.
Flexibility Measurement in Production Systems
by Sven RogalskiThe requirements for production systems are constantly changing as a result of changing competitive conditions. This poses a challenge for manufacturers in the various branches of industry and creates an ever-increasing need for flexibility. With this as a background, this book explores the current developments and trends as well as their impact on today's production systems. It also compares known strategies, concepts and methods used to achieve production flexibility. Similarly, the practical knowledge and current research will be drawn upon and subjected to a sound scientific analysis, through which the technical and organizational flexibility ranges can be measured in their application in a production system. The convenience and usefulness of this concept for manufacturers is substantiated by its implementation in a software tool called ecoFLEX and its practical application, based on extensive examples. This illustrates how flexibility flaws can be quickly identified, classified and properly disposed of using ecoFLEX. This tool helps to close the gap between ERP / PPS systems and digital factory planning tools.
