Standard corporate evaluation approaches are improved by trendy innovation, especially as it concerns technological scale up and environmental issues such as digital networking or ESG compliance. Whereas traditional firm appraisal follows institutional guidelines and best practices, frontier research still must define the boundaries of these trendy issues, linking a strong theoretical background to practical advances that still need fine-tuning. This revised book, written by an academic who is also a senior consultant, combines theoretical rigor with practical insights, providing an innovative framework for researchers, evaluators, managers, and practitioners.
