Sounds very refreshing – lucky you!

I agree the net promoter score is a great measurement of engagement as long as you are able to dig a bit deeper to that you can get a bit of insight into what’s going well and where you need to make improvements.

Perhaps once a quarter you could ask the main question ‘On a scale of zero to ten, how likely is it you would recommend this company as a place to work?”

And then to get deeper insight add in some open questions:

1. What was the main reason for your answer?
2. (detractors) What do you think we could do better?
3. (promoters) Can you describe something you especially enjoy about working here?
4. (passives) What is one thing holding you back from referring friends to the company?
5. What is one thing we could do as a company that might improve your score?

And I like this 2^nd question for advocacy

1. “How likely would you be to recommend our company’s products or services to a friend or colleague?”

Then as you say you can supplement with regular pulse surveys on themes to dig a bit deeper e.g. career development –   Do you feel you are developing your career here? Do you have regular career conversations with your manager? What could we do that might improve that score?

There is a good resource here from Peakon which might help you too!

Good luck and keep us posted!
