Other than a few corrections introduced with the typesetting, there’s one change from the version posted to SSRN (and already cited): we changed Table 3 to Figure 2. By having to summarize the paper to ACAC last May, I found that I had trouble understanding the table (that I’d made) and found the Venn diagram approach much less ambiguous: hence the new Figure (designed in color for my ACAC talk, but printed in B&W in the journal).
The second is the process model, separating how firms handle their use of external innovation into four phases. Those phases are summarized below (as excerpted from Table 4):
Open Innovation Topic
· Technology scouts
· Incentives to share
· Nature of the innovation
· Absorptive capacity
· Culture and “Not Invented Here”
· Incentives to cooperate
· Commercialization process
· Value creation
· Value capture
· R&D feedback
· Customer/market feedback
· Value networks
Finally is the conclusion that research is particularly light on the second and third phase: how external innovations get into firms, and how these innovations are commercialized differently (or similarly) to internal innovations. We are already seeing research agendas influenced by the latter findings.
This version of the article also has the online appendix, which lists all 151 inbound or coupled articles used in preparing this literature review. We asked JPIM to let us publish this online (which is not something we’d seen in this particular journal before). We felt this was important to share with future researchers, both so they would know what inbound (and coupled) literature was written during the period in review (2003-2010), and so everyone see which research we classified as falling in these categories.
We started working on the paper in June 2010: it’s hard to explain to a non-academic why it will be more than four years from when we started the project to when it was published (some of that, of course, being due to deficiencies in the early drafts). Still, it’s gratifying to have the paper out there and being read by those we hope will find it valuable.
