For software manufacturing companies, if you want to objectively evaluate whether the software you write runs well or not, the best way is to use the software itself.
Viet Vang creates CRM software (VV-CRM), then timekeeping software, and Viet Vang himself also uses these software to manage customers and timekeeping for Viet Vang employees. During use, the company’s Human Resources members gave very useful questions, suggestions, improvement requests, etc., and from there the Engineering team knew how to improve.
