I took GP's meaning as "these people need to have basic Excel filtering explained to them, so how can they be expected to deal with various UI/UX changes?" I don't know the answer: at some point a person needs to take responsibility for knowing the tools of their trade. Or a person hiring them needs to take responsibility for hiring people who know the tools of their trade. Either these tools are mission critical and therefore employees should understand how/why they work, or the tools are not mission critical and therefore it's not a big deal when their interfaces change. There's a middle ground there where tools shouldn't change so fast and when they do it should be well documented.
