New RFM: Customer Retention in “Subscription” Businesses

Jim answers questions from fellow Drillers

Topic Overview

Hi again folks, Jim Novo here.

How do you measure likelihood of customer defection when purchase behavior is highly orchestrated or executed due to repetitive billings? Yea, it’s a bit more complicated because “orders” really can’t express any kind of behavioral change, can they? So, you have to find indicators other than sales to provide the triggers. The Drillin’ the Drillin’ …


Q:  Jim, first let me say that I am enjoying your book VERY MUCH!!  Nicely done, and a nice job of integrating it with the CRM paradigm, 1-to-1 etc… I’m reading very slowly and finished the Latency Metric Toolkit.

A:  Great!  Thanks for the kind words.

Q:  I had a couple of questions on the Latency toolkit and the Latency tripwire, especially as it applies to environments with built in cycles for repeat purchases.

I am in a business where our resources are quarterly based, i.e. customers purchase our resource use them for a quarter and re-purchase the next quarter’s resource.  That is, we have a built in pattern, where customers would purchase our resources each quarter.  I was wondering how well I can use Latency with this type of built in cycle or if I would have any problems applying your Latency concepts to it, maybe they apply that much more readily?   In our case we try to call most folks who haven’t purchased within 2 weeks of a new quarter beginning.

A:  Right, a subscription-type business.  This is also an issue with utilities and other like businesses who bill about the same amount each month or have contracts for service (like wireless).  The answer is if the revenue generation really doesn’t represent anything to do with the behavior, then you simply look for other parameters to profile.  For example, a friend of mine was responsible for analyzing the likelihood of subscription renewal in a business that provided the content online.   Increasing Latency of visit was a warning flag for pending defection, and they triggered their most profitable campaigns based on last visit Recency.  In wireless, the correlations are found in payment Latency and age of phone.

New RFM: Snapshots versus Movies of Behavior

Jim answers questions from fellow Drillers

Topic Overview

Hi again folks, Jim Novo here.

The standard RFM customer model is essentially a “snapshot” of likelihood to purchase (and so perhaps also profitability of campaign) at a given point in time. But what if you took these snapshots and turned them into a movie, looking at likelihood to purchase over time, and what specific inputs affected these changes? Then you’d have a LifeCycle movie / model, which amplifies the power of RFM substantially. Ready to find out more? The Drillin’, the Drillin’ …


Q:  I am in catalog circulation.  We currently use RFM to segment the file and then roll the RFM cells into more manageable segments (this is a new technique to me, I am new to this company, in my former company we mailed by RFM segment).

A:  Hmm…this sounds like a “dumbing down” approach to RFM, but hey, if it works, why not.  Sometimes this is done because the customer base is not really large enough to support 125 segments, and the differences between the segments can become unstable and less predictive unless they are aggregated.

Q:  Because we are in a niche market and we saturate it pretty well, I would like to see which customers are on the edge or falling off (the Latency stuff) and which ones we can “reward” for being the best.  I do not think the RFM analysis shows me that amount of detail.

Are Quitters of Club Likely Still Good Customers?

Jim answers questions from fellow Drillers

Topic Overview

Hi again folks, Jim Novo here.

How do you handle the measurement of “likely to purchase” when there’s a built in cycle of purchase as a “member”, like in a book club or other auto-delivery scheme? And what if a member quits membership but keeps buying, what does that mean for predicting future buyer behavior? Oh, the complexity of it all! Let’s do the Drillin’ …


Q:  I just ordered the book too, so I am eager to learn more about SIMPLE ways to implement RFM-based strategies.

A:  Well, thank you for ordering!  I hope it fulfills your expectations.

Q:  In the continuity club (Jim’s Note: flower of the month, book of the month, beer of the month) club business though, a little of the RFM process looks tricky because everyone has a certain Frequency built-in, because of the “repeat” nature of clubs.  Also, we’re starting to see a  phenomenon where customers that drop out of our club continue to order from us.

A:  This is quite normal, depending on how the club is set up and whether or not you make it “easy” for people to continue.  In some clubs, you are either in or not (books, CD’s, credit cards).  Most catalog-type clubs (pay a fee in exchange for ongoing discounts / added services) see continuation beyond club membership.  It’s a volume-based thing and a “rational” decision by the consumer – if you need to buy a lot of stuff, joining the club makes sense, because the discount pays for the membership.  

In your case, it might be more attached to education, for example – you join the club to educate yourself about the products, then quit when you can “do it on your own.”  Or, you get lots of  product to experience the variety, and settle into a specific usage pattern.  This is the Customer LifeCycle at work.  If you can recognize these patterns, you can use them to predict what customers are likely to do next.  If you can predict behavior, you can create very high ROI customer marketing programs.
