| SCORING
After a prolonged obsession with the optimization
of automated collection processes, Quantrax, in 2005, set out to
develop and evaluate its own scoring technology. Since RMEx is probably
the finest workflow engine for account management, a reliable score
would greatly enhance a company's ability to optimally manage its
resources and its bottom line. New scoring systems announced by
the major credit reporting agencies Equifax, Experian and Trans
Union are likely to face challenges in the way that those scores
are interpreted. How these scores affect collection accounts and
later-stage collections will also be interesting and may take time
to be understood. For the collection industry, we believe that the
timing is perfect for new analytical tools that do not rely on traditional
FICO-type scores.
I-Score is a product that has reinvented the rules of scoring for
collection accounts. The compelling design does not utilize
a credit score. Visionary thinking has created an entirely new concept
and results that do not seem possible without access to a debtor's
credit history.
The following were considered as Quantrax evaluated this project
as a technical challenge and a potential business opportunity.
-
We wanted to find a solution that was better and could be priced
competitively when evaluated against other solutions.
-
For Quantrax to build a better solution, they would need a better
approach. We felt that our knowledge of the debt collection industry
was superior to that of other companies. Since we were solving
a collection problem, this could be a great advantage for Quantrax.
-
Traditional approaches rely on credit history and information
from external databases. We were not aware of many companies using
the collection history that was already available within your
company. We believed that your data was a critical part
of any model for scoring collection accounts.
-
Rather than building models based on specific factors that we
know affect the collectability of an account (e.g. age at placement
or balance), we believed that we would obtain better results by
making no assumptions. We decided to start with all of
the data that we knew could affect collectability. We would then
let our model
figure out exactly what circumstances could make an account more
collectable. (E.g. Debtors between the ages of 35 and 40 in a
specific area were more likely to pay a credit card bill than
a medical bill, but the results would be different for similar
debtors and accounts in a different area!)
-
One of the most powerful technologies that are able to analyze
and determine these complex relationships between many variables
is "neural network" technology (neural networks are
based on the parallel architecture of animal brains). Quantrax's
models were totally neural network-based and used the finest mathematical
modeling software that is available today.
-
Quantrax's approach combines the advantages of data mining and
neural network technologies.
-
The key to developing successful neural networks is the selection
and quality of the information that is used to train the network.
One of the keys to Quantrax's success is the selection and manipulation
of the data entities, as well as the application of neuro-fuzzy
techniques to the learning processes.
In
the summer of 2005, Quantrax designed a model based on the above.
From different clients, we downloaded 150,000 to 300,000 older accounts
and used about half those accounts to build a model. Within these
accounts there were paying accounts, accounts from different areas,
accounts that had linked to other accounts, profitable clients and
clients with low recovery rates. After we built the model, we looked
at the rest of the accounts, "hiding" any payment information
from the process. We then used our model to try to predict which
of the new accounts would have paid.
Here
is an example of a test we ran against RMEx data. We looked at about
84,000 accounts and sorted them by what we predicted as most collectable
down to the least collectable. The data is analyzed and presented
in 20 groups. The scores for each group were lower, as you went
down the list of categories. As you will see, the majority of the
paying accounts (any money received) were in the higher groups.
85% of the paying accounts were in the top 50%. If you had only
worked 60% of your accounts, you would have collected from 91% of
the accounts that would have paid! With regard to dollars collected,
92% of the money collected was in the top 60%. Remember that these
accounts were all worked without paying attention to the scores.
In a production environment, more effort would be put into the higher
scores, resulting in even more being collected within those categories.

"Paying
accounts" refers to accounts where some money was collected,
not necessarily a payment in full. Our reasoning was that if you
were able to collect anything from a debtor, the ability to receive
payment in-full is often based on the collector's skills. Identifying
the accounts that could generate any size of payment was the
| The
scores are based on "absolute" and not "relative"
values. This means that the accounts placed at the top of
the list are not automatically assigned high values. If most
of the accounts in a given batch are not considered collectable,
then there will be only be a few accounts with higher scores.

key
to the classification of accounts.
It is important to note the following.
- The
results were obtained with only a company's own data. No
credit data was used.
-
The first 10 groups had 50% of 83,906 accounts that were analyzed.
-
The first 10 groups (the top 50%) contained over 85% of the accounts
that received a payment.
- That
top 50% also had 85% of the dollars collected.
-
92% of the dollars collected were within the first 12 groups,
which represents 60% of the accounts analyzed.
In
the above example, you could have collected 92% of accounts paid
on, by working only 60% of the accounts placed! That knowledge could
translate to faster recoveries at significantly lower operating
costs. Remember that the results are based on real accounts and
are not numbers made up by Quantrax. Most experts would agree that
these are excellent results considering the fact that no
credit scores were used. In our research, we did compare our scores
with some of the "collection scores" supplied by credit
reporting agencies and other scoring companies. Interestingly, we
found that our product (without using a credit score) was able to
identify most of the accounts that received higher scores based
on having a better credit history. Note that the similar results
to those described above were obtained from different Quantrax clients,
in a range of geograrphical areas and for accounts ranging from
fairlyrecent debt
How does Quantrax explain their outstanding results?
We
believe that the following explains some of Quantrax's early success
in the area of scoring.
-
Scoring companies do not understand collection data elements and
collection processes as well as Quantrax.

-
Quantrax's approach used the best combination of engineering,
mathematics and collection industry knowledge. The research and
development teams were made up of some uniquely talented individuals
from the US and Europe, including the universities of Oxford and
London.
- The
Quantrax model utilizes several data elements that have never
been considered by the other scoring companies. We believe that
the inputs are analyzed uniquely and that this contributes significantly
to the results.
- Quantrax's
proprietary manipulation and use of demographic data play a critical
role in the creation of the scoring models.
-
Quantrax's solution is entirely based on neural network technology.
It is generally accepted that neural networks can not be effectively
applied to random data or circumstances. As a result, Quantrax's
initial efforts were to understand if "paying accounts"
were a random occurrence or something that could be predicted
because they fell into what is described in statistics as a "normal
distribution". The logical conclusion is that if all accounts
were worked the same way, some and only some of them would pay.
That leads us to believe that payment patterns and results obtained
are not random. Quantrax was able to prove this,
since its predictions closely matched the actual results obtained.
Quantrax's single-minded focus on neural network technology was
more than justified under the circumstances.
-
The product was developed using the most advanced technology that
is available to solve complex problems that require advanced mathematical
modeling tools. For example, Quantrax's scoring models use the
same software environment that is used by every major aerospace
and defense organization in the world to develop air, naval, land
and space systems.
And
how would you utilize these scores? With RMEx, we provide an interface
that allows you to apply Smart Codes based on the ranges of scores
returned. With our knowledge-based system, you can automatically
change workflows, collectors, letter strategies or work plans based
on the levels of decision-making within the system. Analyzing collection
results based on the scores is also easy. We provide reports that
show paying accounts based on the range of scores, as in the following
example.
As you look at the screens and begin to think about how you could
incorporate scoring into your business model, you should consider
the following.
- No
scoring model can claim to accurately tell you who will and will
not pay.
- There
will always be collectable accounts that will be scored low. Similarly,
you will not collect from many high-scoring accounts.
- Scores
are an indicator and you are always responsible for evaluating
the reliability of any scoring system.
- Our
goal is to provide reliable results for a very large percentage
of the accounts scored.
- Giving
a lower score to some collectable accounts is not damaging if
those accounts get collected quickly or with a little effort compared
to the success with other low-scoring accounts. You could consider
using an additional credit score on some of the lower-scoring
high balances, to find out if they may qualify to be considered
more collectable.
- Assigning
higher scores to accounts that can not be collected will not be
costly if the number of accounts is small. You will have fewer
high scoring accounts and you will not be using a large percentage
of your resources on these accounts.
- Numbers
can also be deceptive. A single large payment can skew the analysis
and this must be considered carefully. In general if a collectable
account was placed in a low-scoring group, there is a good chance
that the account would be recovered with minimal effort. While
it is our recommendation that additional resources and time be
allocated for higher-scoring accounts, we do not suggest that
you put no effort on the lower-scoring accounts! These
accounts must also be worked, but worked economically.
Let us now consider some results after accounts have been worked
based on the scores. In the following, Prof.Index is a profitability
index. It looks at the amount paid for each group, compared to
the number of accounts in the group. Assuming you put the same
resources into all of the accounts in the group, this index is
an indication of the amount collected per debtor, for accounts
within the group. The larger the number, the more profitable those
accounts are likely to be.
In the above analysis, we have looked at a large group of accounts,
only considering the payments received after the accounts
were scored. Note the increase in the percentages of amounts paid
and paying debtors as the scores increase.
- Grp%
is the percentage of paying debtors calculated against the group
size.
- Tot%
is the percentage of paying debtors calculated against the total
number of paying debtors for all groups.
- Cuml.
% shows percentages for all the groups up to and including the
group referred to on that row.
Many of you who utilize scoring, can not effectively analyze the
results and benefits. We have invested in features that will allow
you to review the scored accounts in great depth, helping you to
understand why a scored account may or may not have generated a
payment.
Additional information can also be found within a white
paper on Quantrax's scoring systems.
