How to understand what skills the team lacks?

Question

Work organization

Good afternoon!

There is a relatively small development department in a company for which IT is not the main focus.

Consists of:

1. 1 Head of department
   
2. 1 Lead Back Developer
   
3. 3 back developers
   
4. 1 Junior Back Developer
   
5. 1 Lead front-end developer
   
6. 1 Front-end developer
   
7. 3 Project manager
   
8. 1 Manual tester-consultant
   

And there is 1 more bet. More will not be given at least the next year. How can you understand what exactly is missing in the first place? There are thoughts in the direction of QA, a web designer, or another front. The bosses say "we need another back developer", but they just don't understand the difference)

Answer 1

Make yourself a kan-ban board and see where tasks are delayed.

Answer 2

Developers, you all have a backup. What about QA if he goes on vacation or sick leave?
Who performs the functions of an analyst? Or do the developers know exactly what the client wants?
