Another standard and useful textbook on this topic would be:
Product Design And Development, by Ulrich/Eppinger
Not the funnest or most up-to-date read, but a thorough and useful reference nonetheless.
As for the Roger Martin book:
– It is not going to focus on the ‘product development process’, if that is what you are looking for
– ‘Design thinking is already dead’? Umm, like any buzzword, it had its moment in the sun before the backlash. But much of the thinking behind it is still valid, still the same common sense that existed before the buzzword and will exist after. Let’s try to look beyond the hype and seek the substance, regardless of whether the vocabulary is trendy or not.
