As an exercise during my internship I have conducted a survey questionnaire on a population of 40 employees to test out which initiatives are considered useful, and which are unimportant to them. This means, the only relevant data to me was obtained through a descriptive analysis of all findings. By analyzing all means I was able to find out how important certain areas were to the employees.
But I didn't just ask if they were important to them personally, I also wanted to know how the company was doing in the same areas. In other words, I also asked for the perceived participation of the company in area X. This way, I wanted to figure out if there are initiatives where the company is doing very little or nothing but which are considered important by the whole population.
However, I have a limit on how many initiatives I can propose: a maximum of 3
So I have "designed" a threshold. I have said an initiative is considered relevant if:
1) More than 20% of the respondents noted the participation as 2 or lower, and
2) Less than 10% of the respondents noted that this issue is unimportant for them personally.
Leaving me with the 6 most crucial initiatives. Since each one of them comes from an individual sub-topic I can now take one initiative from each topic, leaving me with 3 initiatives.
Great, but: I cannot base my threshold on any literature. It's just something arbitrary I made up in my mind because it sounded nice. This won't fly.
So my question is: Is there any literature where I can read up on how to define such a threshold professionally? Because I just could not find a damn thing online or in my books.
Whenever I search for "significance" or "threshold" I end up at an article about the p-value, which is not what I am looking for. I am not looking for any correlations between two items here. I just need a threshold value to omit unwanted results.
I know a lot of people here are good at this, so my hope is that one of them reads this :P
Please push me into the right direction

nobody?
Just saying that there is no apparent literature would already be enough
