<p><strong>‘In this elegant book, Kecheng Liu and Weizi Li provide a matured perspective and distil their considerable research base arrived at over many years. They achieve the considerable feat of a very clear rendering of semiotics, then show its application in researching and improving business informatics practice. The accelerating digitization we live with requires semiotics tools for its study; this intervention is timely and important.’</strong> - <i>Professor Leslie Willcocks<b>, </b>Department of Management<b>, </b>London School of Economics and Political Science, UK</i></p><p>‘This deeply academic book provides the means to understand the complexities and difficulties of language and communications in Requirements Engineering which have so often resulted in challenged or failed information systems projects. It complements many previous socio-technical approaches to requirements capture and provides the foundation for understanding why, how and when they work. The final three chapters provide excellent examples of Organisational Semiotics applied to the real world, through a wide range of valuable case studies and contextual analyses.’ - <i>Richard J Self, Senior Lecturer in Analytics and Governance, University of Derby, UK</i></p><p>‘This book considers a highly important issue of business-IT alignment from the view point of organisational semiotics. The author demonstrates quite rare deep understanding of differences between traditional computer science and business informatics. The book contains full coverage of fundamental principles of semiotics blended with practical aspects of requirements engineering and organisational modelling. It makes this source very useful during scientific research and design of information systems for various groups of readers: PhD students, scholars, business analysts and IT professionals.’ - <i>Eduard BABKIN, Professor, National Research University "Higher School of economics", Nizhny Novgorod, Russia</i></p>
