This book fundamentally challenges the way in which PhDs are currently pursued. It applies lean methodologies - which have been embraced by start-ups - to the doctoral research process. It explains how to apply techniques such as the minimal viable product (MVP) approach, rapid prototyping and pivoting to each stage, from choosing a topic to seeking feedback, in order to save time, make the process more efficient and demonstrate impact. Chapters are enriched with insights from PhD researchers, practical guidance on going lean and a wealth of empirical data which supports this new approach to postgraduate research.This inspiring text is a must-read for prospective and current PhD students who wish to accelerate their careers in academia and beyond.
