The link between open innovation and open source has long been documented. That there is a significant correlation is obvious and not arguable, but to what extent is there causation? And in what direction? Open innovation describes a process, whereas open source has traditionally described a product or end result. The ultimate determination of whether a software project qualifies as open source is its license. I posit that the relationship between process and end result is one-way: Open innovation in software will necessarily lead to an open source result, but not the other way around.
