I like that this article is very clear, visual and to the point. From my experience those exact same approaches/models are very useful throughout many situations in business, not only for designers. Consider e.g. sales where you also need to

- show (the customer) how to solve the problem (he/or she has)

- create a clear decision framework (and get the customer on board)

- craft a narrative around our solution

to succeed. There you also need your problem solving skills, a model for decision making and a way to communicate in a way that reaches and convinces your audience.
