Somehow I feel like the word "thereof" doesn't fit well, but I can't put my finger on it. Can you help me decide between the following formulations (or find a working alternative)?
Target is organizational and technical managerial staff, and representatives thereof.
First, I'm not sure if I'm starting the sentence correctly. Would it perhaps be better to write something along the lines of
The target group consists of organizational and technical managerial staff, and their representatives.
or even to insert the word "respectively"? The sentence should describe the target group of an application we wrote, that is, the end users of the application. Any input is very welcome as this is the first time I have to write a business-related text in English.
Edit: Though I'm mainly interested in the American English view on this, I'm also glad for suggestions regarding British English.
