Calculating.
Fixed model assumptions (not editable here): 8-hour day, 5-day week, 80% productive time, 10% attrition, retrofit rework 5% and access failures 8%, replacement rework 8% and access failures 8%, and a ramp-up to full productivity over the first 7 months (40%, 65%, 65%, then 85% for months 4 to 6, then 100%). These are illustrative assumptions, not measured results. The model does not include cost, supply of devices or meters, or the availability of licensed tradespeople in any market.
Before you start

See how long a retrofit reading device programme and a full meter replacement programme could take at different scales, and how many workers each needs, using install times you set.
