SIGNUM DNA
A Word About Our Data …
As we have integrated our Signum DNA into Telescope, our Self Service Analytics platform for communications insights, what better way to promote one of the UK’s largest enterprise based expense management research and analysis data warehouses.
We process in excess of 1M active subscriptions, 2.5 petabytes of data usage, 200M voice minutes and 25M SMS events per month:
- All voice volumes are reported in minutes
- All data volumes are reported in Gigabytes (Gb)
- Each SMS/MMS as a single event record
Using a 5 month average (inclusive Nov’19 to Mar’20) as our baseline, we wondered how usage had changed and what our “new normal” looks like.
