2. Over a six-year period, the CEM [Customer Experience
Methodology] generated measurable improvements in key
metrics as high as 200%, in one recently reported project.
Typically the improvements fall within the range of 40% to
150%. Key metrics measured depend on the client, but in
the past have included revenue, cost savings, conversion
rate, customer or user acquisition rate, and retention cost.
