In later work, Schumpeter acknowledged this and emphasised the need for a systematic study of ‘co-operative’ entrepreneurship in large firms (so-called ‘Schumpeter Mark II’). However, he did not analyse the phenomenon in much detail, although he strongly advised others to.
Systematic theoretical and empirical work on innovation projects in firms (and the management of such projects) was slow to evolve, though. But especially during the last few decades a quite substantial literature has emerged.
