A topic that has been covered in my courses at university, that is also of relevance in day-to-day life, is communication styles. Within teams where people communicate indifferent way, how could a company ensure that communication is of high quality.

When I ask what thinking habits do they have that makes their list above hard to accomplish in their current context, a list similar to this appears:
When I observe they not only know what effective communication is (from list 1) but also what gets in its way (list 2) and suggest the solution lay not in acquiring new skills, tools and techniques but in dissolving or downplaying the thinking habits that are holding them back, they usually agree.
