Employers care very much when you point them to the hidden underlying needs that are dissuading users from using their products because you were given high quality training in how to ask non-leading questions.

I've been on several workshop facilitation and project management courses along with leadership skills like negotiation and persuasion delivered as in-house training courses as part of the corporate training programme organised by HR. That's basic stuff everyone learns at work like Word and Excel if you work in a large company.

The factual business knowledge can be picked up at Coursera - Wharton, IESE and other business schools do short- and medium-length courses there and there's even a full MBA if you have $20k.

I got a lot of my workshop activities from Alex Cowan's entrepreneurship and product management courses. He teaches them at UVA Darden business school, but I learned them at Coursera. Every time I deliver a workshop, I receive an immediate request to deliver the same to someone else. The templates have become "the way we do things here" for several large companies I've worked in.
