Knowledge-intensive product realization implies embedded intelligence; meaning that if both theoretical and practical knowledge and understanding of a subject is integrated into the design and production processes of products, this will significantly increase added value. This book presents papers accepted for the 9th Swedish Production Symposium (SPS2020), hosted by the School of Engineering, Jönköping University, Sweden, and held online on 7 & 8 October 2020 because of restrictions due to the Corona virus pandemic. The subtitle of the conference was Knowledge Intensive Product Realization in Co-Operation for Future Sustainable Competitiveness. The book contains the 57 papers accepted for presentation at the conference, and these are divided into nine sections which reflect the topics covered: resource efficient production; flexible production; virtual production development; humans in production systems; circular production systems and maintenance; integrated product and production development; advanced and optimized components, materials and manufacturing; digitalization for smart products and services; and responsive and efficient operations and supply chains. In addition, the book presents five special sessions from the symposium: development of changeable and reconfigurable production systems; smart production system design and development; supply chain relocation; management of manufacturing digitalization; and additive manufacturing in the production system. The book will be of interest to all those working in the field of knowledge-intensive product realization.

Surf the waves of change. We are no longer an economy of products and services. The digital transformation demands that we focus our attention on experiences and outcomes. Business leaders and their organizations must shift to keeping promises—no matter how their customers interact with them. But organizations no longer control the conversation. In this era of social and mobile technology, customers, employees, suppliers, and partners are in direct communication with one another. Those personal networks and the brands they’re passionate about influence their decision making and their spending. The workforce has changed too. Employees expect to be able to determine when and how they will work, the technology they’ll use, and the values their company will espouse. Organizations can take part in this conversation only if they recognize how and where it’s happening. Resisting these changes will leave executives, managers, and their companies powerless. Organizations must pivot with and ahead of these social, organizational, and technological shifts or risk being left behind. Technology guru Ray Wang shows how organizations can surf the waves of change—how they can keep their promises. Current trends, when taken seriously, require a new way of thinking about business that includes five key areas: 1. Consumerization of technology and the new C-suite 2. Data’s influence in driving decisions 3. Digital marketing transformation 4. The future of work 5. Matrix commerce Digital disruption has changed how we do our work. But by mastering these trends you’ll delight your customers with every interaction.
Much has been written about Covid-19 victims, how scientists raced to understand and treat the disease, and how governments did (or did not) protect their citizens. Less has been written about the pandemic’s impact on the global economy and how companies coped as the competitive environment was upended. In his new book, "The New (Ab)Normal", MIT Professor Yossi Sheffi maps how the Covid-19 pandemic impacted business, supply chains, and society. He exposes the critical role supply chains play in helping people, governments, and companies to manage the crisis. The book draws on executive interviews, pandemic media coverage, and historical analyses. Sheffi also builds on themes from his books "The Resilient Enterprise" (2005) and "The Power of Resilience" (2015) to enrich the narrative. The author paints a compelling picture of how the Covid-19 virus is changing many facets of human life and what our post-pandemic world might look like. This must-read book helps companies to redefine their business models and adjust to a fast-evolving economic landscape. The stage is set In Part 1 of the book, “What Happened,” the author looks at how companies fought to mend the global economic fabric even as the virus ripped more holes in it. Part 2, “Living with Uncertainty,” views the crisis through a supply chain risk management lens derived from Yossi Sheffi’s previous books. This perspective shows how companies create corporate immune systems to quickly recognize and manage large-scale disruptions. The ongoing pandemic is creating a new normal in life, work, and education—covered in Part 3, “Adjustment Required.” Consumer fears about the contagion as well as government mandates require businesses in industries such as retail, hospitality, entertainment, sports, and education to create “safe zones” for workers and customers. Many elements of the book – especially in Part 4, “Supply Chains for the Future” – show how the virus accelerated preexisting trends in technology adoption. China was the epicenter of the pandemic; it also was the first nation to be disrupted and recover. Part 5 of the book, “Of Politics and Pandemics,” explains why reports that companies are abandoning China in favor of other offshore manufacturing centers do not reflect reality. Fundamentally, The New (Ab)Normal is about businesses trying to create a better future in a time of extreme uncertainty – a point emphasized in Part 6, “The Next Opportunities.” The outlook is not necessarily gloomy. The advance of technology is accelerating, a trend that can level the playing field between small and large companies. Nimble small businesses are using a growing array of off-the-shelf cloud computing and mobile apps to deploy sophisticated technologies in their supply chains and customer interfaces. The New (Ab)Normal Another new normal is working from home. Remote working enables individuals to live anywhere and companies to recruit talent from anywhere. Education, especially higher education, faces a major disruption (and major opportunity) that is likely to shake the high-cost model of in-person education in favor of online or hybrid education. Regrettably, the book recognizes one trend accentuated by Covid-19--the growing inequality, and anticipates that the new normal will be more stratified.
