In the 14th edition, the text, already considered a classic, is beginning to show signs of obsolescence. Its approach to Industry 4.0 is modest, limited in the context of regional operations and the need to provide an adequate framework for post-COVID management. Yes it´s time for a reengineering; cosmetic adjustments are no longer sufficient.
In investment project analysis, the approach is poor and misguided. It is unrealistic to assume uniform cash flows in operational projects, and ignores key aspects such as the today variability of reference rates or the recovery value of fixed assets. This is a reminder that OM experts should concentrate on writing about Operations, respecting other disciplines boundaries. What is the need?
However, it is undeniable that it remains a conceptually reliable book, well structured and with numerous and varied pedagogical resources. So, expected for a good textbook. The editional work is very well cared, and it is no coincidence that it remains as a best seller in Operations Management.
Despite some limitations, I still value this text. I have owned, read and kept 10 editions of H&R, and I will continue to recommend it, recognizing its legacy in the field.
