How to assemble a team to test the operation of the online system?

Question

CRM

We are developing a CRM system, we want to assemble a small team for an objective assessment of the usability of the system. Based on all the wishes, conclusions will be drawn on what should be finalized in the first place, and what - later.
Could you tell me how and where it is better to organize such testing?

Answer 1

Find a potential client and let him work with the system for a week. Sit down and listen to users.
Testers - NON-users will be ineffective.

Answer 2

Offer money!

Answer 3

Without proper motivation (monetary or otherwise), people will not have an incentive to conduct quality testing.

Answer 4

Start using it yourself in your work on your project. For starters, that's enough.
