On one side, you have two colleagues, with similar competences, juggling more or less at the same time the following tasks: client booking via phone call, client support via phone call, client data collection and entry, service delivery, invoicing, and payment collection. This is a mess.
On the other side, you have two collegues, with similar competences, alternating on their tasks more or less as follows: one does client booking via phone call, client data collection and entry, invoicing, and payment collection; the other one focuses on service delivery and client support via phone call. This is a process.
We use to think of processes as the main reason for inefficiencies and disengagement, but the right process in the right place can do wonders. And the client is the one benefitting the most.
