Of course you don’t know how to capture your Customer Experience Score. You’ve never done it before.
There are many things you’ve never done before, but if you decided you wanted to learn one of them, you would know how to go about it wouldn’t you?
You might get yourself set up with whatever kit you need and have a go. That’s hard to sustain, because even before trying to acquire whatever skill you’re trying to master, you have to know what you don’t know. Years ago, I thought I’d learn to play the melodeon. I bought the wrong sort, which made it more difficult to play the tunes I wanted to learn, which in turn made it even harder to get my fingers in the right places. I didn’t last long.
Or, you could find someone who does know, check out their track record of doing it, and ask them to teach you. There’s nothing quite like learning by doing, accompanied by someone showing you how, explaining why it’s done this way and holding you accountable for doing it. That’s how I learned to speak Spanish and to do Pilates, skills that have stuck with me ever since. It’s by far the quickest way to really learn.
Of course, once you’ve acquired your new skill, the best way to carry on developing and improving it is to pass it on, and teach the others.
