It has already been extended into software development. Plenty of software projects have to be signed off in aerospace, automotive, telecoms, energy and defense. In fact I'd be amazed if it did not extend into consumer electronics in large companies, e.g. Apple et al cannot risk bricking millions of phones with a bad update. The point might be that there are thousands of badly run projects, just as there are in construction.
