Topics Overview

Hi again folks, Jim Novo here.

This month, we're looking at using multiple models for the same customer.  For example, sometimes one model is best for the early stages of the LifeCycle, and another model is better for the later stages of the LifeCycle.

We also have a couple of great customer marketing article links.  The first is Don Peppers spinning database marketing his way; they really do a good job of reinventing this stuff.   The second speaks to an idea many disagree with but I promise you, analytics will someday move out of the silos and into an "analytics department" reporting directly to the C-level.

Trust me on this one.  The more heavily your company relies on analytics for success, the more likely this "analytical rollup" is to occur.

Best Customer Retention Articles

Seven Rules for Increasing Customer Value
June 4, 2005  InsightExec
Don Peppers expounds a bit on the Peppers and Rodgers Return on Customer (ROC) model.  Same old stuff from a databased marketing perspective, but I have to give them credit, they do have a knack for inventing new, more understandable ways to tell the story!

The Secret to BI Success
June 14, 2005
Back in the old days we called it the "Research and Analysis department"; looks like today's name is "BI competency center".  No matter, it's the same idea - get analytics out of the silos and into a single, powerful group reporting directly to C-level operations or finance.  Highly profitable problem-solving is cross-functional; the power to find new ideas and solutions is magnified many fold when all the analysts work together.

Questions from Fellow Drillers

Customer Retention in Durable Goods

Using Multiple, Related Customer Models

Q:  We recently purchased your book

A:  Thanks for that!

Q: and we are ready to start building some RFM analysis.  We are a search marketing business - we have a large customer /prospect base.  We have limited knowledge about them and we are keen to start on the journey.

A:  OK...let's see what you've got.

Q:  We are hoping to extract database (approximately 25k names) of the last 6 months records and do some RFM analysis on key customer groups.   Specifically:

TEST GROUP A - people who initially purchased one of our trial products - we want to know what is their RFM score.

TEST GROUP B - subscribers to our "tool kit" product at $50 / month - we want to know what is their RFM score.

Q:  What kind of data are we talking about?  Is it web site visits, clicks on emails, transactional / subscription data, all of the above?

A:  Before setting up the model we have a couple of questions we hope you can shed some light on:

1.  How do we treat subscription - our business has a mix of one off and subscription business - if someone "buys" every month with a subscription, is that included in Recency & Frequency?  Any insight you can provide us would be great - we found some info on this in the book but unsure given ours is a mix of subscription and one off.

A:  Well, let me start off by saying that your primary goal is to understand the customer LifeCycle so you can use it to increase your profits.  If you can understand the LifeCycle, you can discover the most profitable ways to acquire customers and stimulate demand from them.  Which behavioral model (RFM, Recency alone, Latency, or LifeCycle Grids) is best suited for this task is something you will have to discover.  You're probably jumping the gun a bit (I'm guessing) to hop right on to using the RFM.  Before thinking about the models, you should probably do some thinking about segmentation - what logical groups of customers do you have, and what is likely the best model to score each segment with?

I'll walk you through some of the thinking...

First, it is perfectly acceptable to use different models on different segments, in fact, often more desirable.  The one-off business - if you
mean the purchase of products sequentially over time - is suitable for RFM analysis, it's a "retail" business segment.  The most Recent and Frequent buyers of these one-off products are the most likely to purchase another one.

As you map promotional response to RFM score, you will see that there is a score that represents customer defection - response falls off rapidly below this score.  This score is your "trip wire", it basically tells you that unless you get people with this score to purchase again, you have likely lost them.

Further, if you include the original source of the customer in the scoring process, you will find certain sources tend to create customers with consistently high RFM scores and others tend to create customers with consistently low RFM scores.  This fact should allow you to better balance marketing spend, shifting spend from low score to high score new customer campaign sources.

The subscription business is something different, and probably requires a different approach.  For example, you might look at "average subscription length" to determine a "trip wire" for customer retention efforts.  If the average subscription length is 8 months, you know that in the eighth month of any sub's tenure, you should be proactive in retaining them.  So for example, subscribers in their 8th month should be offered a renewal "bundle":  "Renew for another 3 months and get 20% off".  This will in effect drag a bunch of potential 8 month defectors into 11 months, where they have a better chance of "sticking" with subscription.

Two models for two distinct segments.

But, if I understand your business model, you have a fairly typical direct marketing of services approach - you acquire customers through free or low priced offers (these are also the one-off products?) and once customers gain confidence, you attempt to upgrade them (these are the subscription products?).  So what you really should be paying attention to is the "flow" of the customer through this expected LifeCycle, then use the models to alert you to opportunities to increase profits along the way.

One way to do this is to deconstruct the LifeCycle of best customers.  Extract your best customers and look at the event sequences.  What series of events occurred, and what was the timing of these events, that lead to the creation of these best customers?  

Then, use this real world LifeCycle pattern to improve the profitability of your marketing efforts.  This approach is the basis of my LifeCycle Grid model, and it's extremely powerful because you are using the two rules of High ROI Customer Marketing to your highest and fullest advantage:

1. Don't spend until you have to

2. When you do spend, spend at the point of maximum impact

So, to follow through with the example above:  Let's say you are running
your two models on the two segments - the RFM model / one-off segment and the Average Subscription Length / subscription segment.  If the LifeCycle is as described above, best customers probably come in through the one-offs, migrate to being high RFM score customers in the one-off segment, then convert to a subscription and end up in the subscription segment. This conversion to subscription is clearly a "tipping point" of some kind - the point of maximum impact.  Well then, when does this occur?

Further analysis of best customers shows that the conversion to subscription typically occurs when a one-off customer achieves a RFM score of 444 or higher, and the conversion to subscription takes place on average within 30 days of a customer achieving this 444 RFM score.  

Knowing this, what can you do?  Think about it.

First, when a customer achieves a 444 RFM score, you know this customer has high potential to become a best / subscription customer.  So it would be worth it to you to focus on these customers, do something special for them, stroke them in a special way beyond the regular e-mail newsletter.  How about calling them and thanking them for their business?  Sending them a special e-book?  Adding a new software service free?  Divert resources from low ROI marketing activities to pay for this High ROI marketing activity.  Same budget, higher profits.

Second, you know there is a clock ticking.  You have 30 days to convert this customer to a subscription customer.  After 30 days, they will start becoming less and less likely to become a subscription customer.  It's now or never.

You now have all you need to fulfill those two rules of High ROI Customer Marketing for this segment:

1. Don't spend until you have to

2. When you do spend, spend at the point of maximum impact

You have just created a dynamic, action-oriented, custom-built, LifeCycle-based behavioral model for a particular segment.  A model customized to your business and one that self-adjusts to customer behavior dynamically.  What does that all mean for you?

It means that if it takes somebody a year to hit 444, that's fine, you don't waste a lot of effort marketing subscriptions to them - they are not ready anyway.  If someone hits 444 in 2 months, you are tipped off to act on subscription marketing in a big way.  Instead of treating every customer the same, regardless of their behavior and potential value to the company, you are allocating resources to customers based on a model that guarantees to increase your profitability.  And because it is all driven by simple numbers and time stamps, you can completely automate not only the scoring and "trip wires" but the marketing as well.  Same marketing resources, deployed in a smarter, more profitable way.

Then you take the next segment, then the next, then the next.  Let's say you find that if a one-off buyer has not bought a subscription within 1 year of first one-off purchase, they are highly likely not to *ever* buy a subscription.  Well, stop marketing subscriptions to them at the 1 year trip wire.  Market one-offs, or create a new product that would appeal to this group.  Develop a model for each segment, and automate.

Q:  2. Do you capture RFM score monthly and track - if so does that mean you need to apply a date stamp for e.g. to the score?

A:  You can look at RFM scores on a sequential basis if you have a plan of action to take advantage of that knowledge.  Rising scores indicate rising potential value to the company - these are best buyers in the making.  Falling scores indicate the beginnings of customer defection.  This is the customer LifeCycle playing out in front of your eyes.

You could use this data to manage marketing activity at the individual level, though it's pretty granular and would take a lot of resources; pretty advanced stuff and in the beginning, better to stick with segments and learn.

However, in the aggregate, you could create reports that look at the "delta" from month to month, basically predicting the future value of the business - is it rising or falling?  With this, you could answer this question: Is our marketing creating customers with high future value?  The approach is similar to the "delta grids" in the LifeCycle Grid part of the book, it's a "migration" report showing you how customers are moving though the LifeCycle.

For example, you could create a report that answered this question: 

Of all customers with a score of over 55X (rocket fuel customers) 6 months ago, where are they now?


35% 55X
25% 4XX
15% 3XX
15% 2XX
10% 1XX

This result isn't particularly significant by itself.  However, when tracked on a monthly basis over time, if you saw increasing defection in the high end and growth in the low end, trending towards something like this (compare with the table above):

15% 55X  (down 20 % points)
15% 4XX  (down 10 % points)
20% 3XX  (up 5 % points)
25% 2XX  (up 10 % points)
25% 1XX  (up 15 % points)

that would literally mean the future sales (potential value) of your customers is falling; something you are doing (probably in marketing or service) is working against you.  Put another way, sales in the future will be lower on a per customer basis than they are today.  However, if you saw retention in the high end and defection in the low end, trending towards something like this (compare with first table above):

40% 55X  (up 5 % points)
30% 4XX  (up 5 % points)
10% 3XX  (up 5 % points)
10% 2XX  (up 5 % points)
10% 1XX  (up 0 % points)

that would literally mean the potential value of your customer base is growing - you are acquiring higher value customers and  / or retaining a higher percentage of high value customers.  Sales in the future will be higher on a per customer basis than they are today.  This kind of crystal ball on future sales and profit can be very valuable indeed!
