Introduction
“Congratulations to the graduates of the inaugural class of the University of WashingtonProfessional and Continuing Education Business Analysis Certificate course. The
Decision Model was featured in this course and included detailed development of Rule
Families and Decision Models.”
These are the words of Charles Bozonier. He is a Principal Business Analyst of Gear and
Apparel at REI.
REI (Recreational Equipment Inc.) is a member owned co-op, selling outdoor recreation
gear, sporting goods, and clothes via some 125 retail stores in about 30 states, catalogs,and the Internet. Charles specializes in requirements facilitation workshops, root cause
analysis, detailed functional specifications, data analysis, strategic planning and business
case development.
Why feature Charles in this column? He is a change agent in at least two ways. First, he
tested and succeeded with The Decision Model in his corporate job. Second, as a
Business Analysis Instructor at the University of Washington (UW) Professional &
Continuing Education, he teaches the Decision Model.
First Step: The Decision Model in the Corporate World
Like most business analysts, Charles captured business rules as part of requirements
gathering. Also like most business analysts, he followed traditional business rules
approaches. These included writing individual business rule expressions, storing them
outside the confines of process models and use cases, and providing pointers to them.
However, he changed his approach after experimenting with The Decision Model.
A significant experience was dealing with a credit card company mandate. Credit card
companies release mandates to issuers of credit cards and merchants who are to
implement changes in the way the credit card is to be processed. The issuers and
merchants must comply with a mandate or suffer increased fees and sometimes-
substantial financial penalty. It comes as no surprise that sometimes the mandates are
difficult to understand, let alone automate. It becomes the business analyst’s

responsibility to bridge the gap between what the mandate says and how to implement it
in technology.
This particular mandate contained three parts, only one of which was relevant to retailers
and ETtailers. The part relevant to ETailers itself contained several parts. Peoplestruggled with how to interpret and represent the mandate correctly. Charles identified a
decision within the mandate and created a decision model for it.
One of its Rule Families is in Table 1. It determines the kind of reversal a credit card
transaction is eligible for: full, partial or none. The conclusion depends on three condition
fact types: Order Amount, Shipment Date and Inventory Quantity. This Rule family is a
dependent Rule Family to another one. The other Rule Family comes to a conclusion
about whether an order is eligible for later shipment. The IT professionals were quickly
able to understand the Rule Families and deploy them.

Table 1 : Sample Rule Family for Credit Card Mandate
In 2010, Charles spoke at BA World in Seattle on “Business Rules, Agile and the New
Decision Model” [2]. The objectives of his presentation were to establish a standard
business rule method, leverage business rules with decision modeling, and utilize

On April 25, 2011, Michael Grohs (VP Marketing KPI) and I visited Charles‘s class.
People enrolled in the Systems Analysis and Design course, advisory board members as
well as business students from the UW main campus were also invited to attend. After
sitting through a presentation on the basics of The Decision Model, the class participated
in an exercise in creating an initial Decision Model Diagram as shown in Figure 4.
Figure 4: Initial Decision Model Diagram
The class continued with populating the Rule Family for Applicant Likelihood of
Defaulting on a Loan because the fictitious business leaders stated that this is where thecurrent business crises are occurring. The fictitious business leaders provide the
following thoughts:
1. Let’s start with four criteria:
o Other Loan Status
o Credit Card Balance
o Outside Credit Rating
o Inside Credit Rating
2. We need to be conservative. Let’s only allow a “low” default probability when all
criteria are the best they can be which is Other Loan Status of A, Credit Card
Balance < $10k, Outside Credit Rating of A, and Inside Credit Rating between 1
and 3 (our best credit ratings).
3. Let us only allow a “high” default probability for worst case, Inside Credit Rating

Spreading the Word
Charles continues to spread the word and success with The Decision Model. He was the
keynote speaker for the IPMA conference in Olympia, Washington in 2011. He featured
the Decision Model as a key component in the success to revamp the REI ecommerce payment systems in an agile framework. His presentation, very well received, resonated
with people there. There were 170 attendees.
Wrap Up
There is growing interest in The Decision Model among business analysts and related
conferences. Other academic institutions are likely to incorporate The Decision Model
into business analyst curriculums, if they have not already done so. As Charles says,
“Having the decision model in the toolbox of business analysis techniques is a
fundamental part of the way forward in the development of agile business solution
development.”
