Yes it could... but sometimes the next problem is how do you aggregate
it. If 5 clients said "great", 3 said "decent" and 2 said "crap" then
what is the aggregate province value for the data element? This is
were the anonymous events and beneficiary aggregation are helpful -
you can create data elements "clients who said it was great", "clients
who said it was crap", "total clients" etc, map the case-based data
onto those elements and then make useful indicators and statistics out
of it.
