So what sort of information is in a piece of the puzzle? And how can it be collected?
SeeTell - A Missed Call System
Every morning, Efie adds chlorine to the water. On Monday, she realises that she does not have enough chlorine and will need more. However, the organisation that typically supplies chlorine only comes once a month. Fortunately for Efie, she has a basic cellphone and is equipped with SeeSaw's SeeTell sheet.
This puzzle piece represents a 'missed call' Efie made on 22/03/2017 at 8:25am to signal that she needs more chlorine.
SeeTell is a system based on 'missed calls' -- a tool that can be used on any type of cellphone, is free for users, and is as simple and quick as dialling a few digits. Efie makes a 'missed call' to a pre-determined number that means she has run out of chlorine.
