Call Drop RCA, 2-Button TV Remote and OTP Login

Assignment 1

Justdial connects buyers with suppliers via Web, Mobile Web, Android App and iPhone App.

There is a virtual number (VN) allocated for every supplier listed with Justdial which is used for tracking purposes.

For e.g. a supplier has an actual number 123 and we allocated a virtual number 456 to this merchant. On the Justdial portal, we show only 456 virtual number on the supplier details section and when the buyer calls up 456, we forward the call to 123 to connect with the supplier. By calling up on 456, we are able to keep a track on who has called the supplier and help us to provide a monthly report to the supplier on the number of calls generated via Justdial portal.

On 22-Nov-2024 (Friday), there was a drop of VN calls by 20% compared to the preceding 3 Friday. Please define a detailed root-case analysis flowchart to identify the reason of drop.

Also, In the TV remote design – There is NO voice command or NO gesture movement allowed or 2-in-1 button allowed (i.e. looks like a single long button, but underneath there is 2 buttons – This is not allowed).

Functionalities needs to be accommodated within 2 tactile buttons only.
