The findings of this working group were then validated by a random sample of practicing analytics professionals. Feedback from this survey resulted in slight modifications of the performance domains, tasks, and knowledge that comprise the test blueprint that determines the content of the CAP® examination. The table below includes the final domains and their representation on the certification exam that were derived from the JTA and a review of validation survey recommendations. Domain Approximate Weight I. Business Problem (Question) Framing 12%–18% II. Analytics Problem Framing 14%–20% III. Data 18%–26% IV. Methodology (Approach) Selection 12%–18% V. Model Building 13%–19% VI. Deployment 7%–11% VII. Model Life Cycle Management 4%–8% The INFORMS CAP® examination is based on the following test blueprint derived from the JTA process. The final agreed-upon weights reflect the percentage of questions from each domain that will be included in each test form. The JTA and the test blueprint resulting from this process will be reviewed periodically and updated as needed to reflect current practices in analytics. The following list of domains also includes the key tasks associated with each domain. (12%–18%) Domain I Business Problem (Question) Framing (The ability to understand a business problem and determine whether the problem is amenable to an analytics solution.) T-1 Obtain or receive problem statement and usability requirements T-2 Identify stakeholders T-3 Determine whether the problem is amenable to an analytics solution T-4 Refine the problem statement and delineate constraints T-5 Define an initial set of business benefits T-6 Obtain stakeholder agreement on the problem statement (14%–20%) Domain II Analytics Problem Framing (The ability to reformulate a business problem into an analytics problem with a potential analytics solution.) T-1 T-2 State the set of assumptions related to the problem T-4 Define key metrics of success T-5 ® Develop a proposed set of drivers and relationships to outputs T-3 5 Reformulate problem statement as an analytics problem Obtain stakeholder agreement
