Question Time: Can Kaizala end the use of WhatsApp within the Organisation?

Kaizala is a simple and secure mobile chat app for work. Described as the business version of WhatsApp (Web CMS, 2019) and designed as a Microsoft Garage (@MSFTGarage) project, it is now being used by over 1000 government and private businesses in India and has 1 million users in the country where it was first launched (Hindustan Times, 2018). It's recent success has prompted Microsoft to introduce it into all Office/Microsoft 365 tenants globally. Whether WhatsApp is being used as an informal communications app to bypass formal channels, or whether users they have been driven to use it through dissatisfaction with existing solutions, will we see Kaizala spell the end of the use of WhatsApp within organisations in the near future?
