Hi Justin,
We had the exact same problem. We don't have RCA and are not connected to a CRM. Our solution was to set up an analytics report based on Lead Routing/Scoring. Our awesome consultant, Maneeza, figured this out for us 2 years ago.
For each of our major areas we want to measure (members of certain industries, contacts who have expressed an interest in specific products, members of specific marketing programs, etc.) we created an analytics report for EACH that I subscribe to monthly.
The report shows that for product x, we have x people who have a score from 1-19, x with scores of 20-59 and x from 60-100. For us, 100 = MQL. (see below)
I plug those numbers into an excel stacked bar chart. There is a separate bar for each product or interest area that our management wants to track. (see below)
Its a lot of manual work each month, but it is a great way for management to understand the marketing pipeline in a snapshot.
If I were more diligent, I could subtract the previous month from the current month to show monthly growth. But that would be a lot of work for all 4 buckets (1-19, etc.) for every program.
When we licensed Marketo we thought this was something Marketo could do for us without all the manual effort.
Example of a Marketo Lead Routing report for a single product or industry (or whatever you want to measure)
