This book shows how to do systems thinking and translate that thinking into praxis (theory informed practical action). It will be welcomed by those managing or governing in situations of complexity and uncertainty across all domains of professional and personal life. The development of capabilities to think and act systemically is an urgent priority. Humans are now a force of nature, affecting whole-earth dynamics including the earth´s climate - we live in an Anthropocene or Capitalocene and are confronted by the emergence of a ´post-truth´, ´big data´ world. What we have developed, organisationally and institutionally, seems very fragile. An imperative exists to recover whatever systemic sensibilities we still retain, to foster systems literacy and to invest in systems thinking in practice capability. This will be needed in future at personal, group, community, regional, national and international levels, all at the same time. Systems Practice: How to Act is structured into four parts. Part I introduces the societal need to invest in systems thinking in practice, in contexts of uncertainty and complexity epitomised by the challenges of responding to human-induced climate change. Part II unpacks what is involved in systems practice by means of a juggler isophor; examining situations where systems thinking offers useful understanding and opportunities for change. Part III identifies the main factors that constrain the uptake of systems practice and makes the case for innovation in practice by means of systemic inquiry, systemic action research and systemic intervention. The book concludes with Part IV, which critically examines how systems practice is, or might be, utilised at different levels from the personal to the societal.

Since the 70s, the C preprocessor is still widely used in practice in a number of projects to tailor systems to different platforms and application scenarios. In academia, researchers have criticized its lack of separation of concerns, its proneness to introduce subtle errors, and its obfuscation of the source code. To better understand the problems of using the C preprocessor, we conducted 40 interviews and a survey among 202 developers. We found that developers deal with three common problems in practice: configuration-related bugs, combinatorial testing, and code comprehension. To better deal with these problems, this book presents strategies to detect bugs and bad smells in preprocessor-based systems based on variability-aware analysis and sampling. This work presents useful findings for C developers during their development tasks, contributing to minimize the chances of introducing configuration-related bugs and bad smells, improve code comprehension, and guide developers to perform combinatorial testing.
