The other vital consideration is ensuring the data you collect remains accurate. Or at least knowing how to identify inaccuracies when they occur, and how to react to them.
For instance, how will you respond to unusual spikes or dips in your figures? What is the best way to resolve them? And how will you incorporate those anomalies into your reporting until they are resolved?
Having robust and repeatable processes in place for all of these things will help you to produce the most accurate results from your data – and keep pace with the uptick in auditing that we can all expect in the next few years.
