An Overview of CBIP
CBIP Specialties Overview of Specialties FIVE CORE DISCIPLINES
The field of business intelligence logically segments into five core disciplines: • Leadership and Management with attention to both program and project levels of BI activity. • Business Analytics concentrating on applied measurement as a business management tool. • Data Analysis and Design that is essential to provide the data-toinformation foundation of BI. • Data Integration as a core discipline to achieve consistency, cohesion, and continuity of business information. • Administration and Technology that is necessary to create and sustain a business intelligence infrastructure.
Business intelligence is both a business and a technology endeavor. BI BALANCING success depends largely on bringing business and technology together in BUSINESS AND TECHNICAL SKILLS the right ways. Every BI discipline demands knowledge of both business
and technology. The balance of business and technical literacy, however, is variable depending on the discipline. The chart on the facing page illustrates a practical balance between business and technical literacy for each of the five disciplines. An ideal business analyst, for example, attains a body of knowledge and skill that is approximately seventy percent business focused and thirty percent technically focused. At the opposite end of the spectrum, an administration and technology professional has strong technological knowledge combined with sufficient business knowledge to apply and manage technology in a meaningful business context.

An Overview of CBIP
CBIP Specialties Job Roles and Specialties BI ROLES
The job roles for effective business intelligence typically divide into six categories: • • • • • •
Business Roles Management Roles Architecture Roles Requirements Analysis Roles Design and Construction Roles Infrastructure Roles
These roles describe groups of activities and responsibilities that are generally assigned to an individual. Roles are not synonymous with job titles. It is common, especially in smaller BI teams, for one individual to assume multiple roles.
MAPPING ROLES TO SPECIALTIES
Each role depends on BI disciplines – understanding of and experience with a specific body of knowledge and skills – to be effective. Mapping roles to disciplines helps to identify the specific skills needed to perform in each role. The table on the facing page maps roles to disciplines using the following classification: • Understanding of the discipline is essential. These are critical skills for the role. • Understanding of the discipline provides valuable knowledge to be highly effective. These are important skills for the role. • Knowledge of the discipline is useful and may aid performance in the role. These are valuable skills for the role. • Knowledge of the discipline will be helpful to teamwork. These are “nice to have” skills for the role.

An Overview of CBIP
Levels of Certification Certificates vs. Meaningful Credentials CERTIFICATION
The primary purpose of certification is to create sustainable value for individuals and for organizations. Individuals want credentials that bolster confidence in their abilities and communicate a recognizable level of expertise. Organizations want knowledgeable employees who can apply their expertise to meet organizational goals.
KINDS OF CERTIFICATION
The word “certified” has unfortunately been abused by some to become synonymous with “certificate.” One well-known consulting group, for example, suggests that you “become a certified metadata professional” by attending a two-day class. It takes little reflection to realize that this program doesn’t offer knowledge and skill certification, but a simple certificate of attendance. The value of certification is proportional to the amount of time and effort required to achieve that certification. Three kinds of professional certificates/certification are common: • • •
Attendance-based certificates documenting attendance of a class. Education-based certification documenting immersion in a body of study and completion of a planned learning process. Examination-based certification documenting demonstrated skills and knowledge through formal testing.
Each level from attendance-based to examination-based is increasingly demanding to achieve, with a corresponding increase of individual and organizational value.
PRINCIPLES OF CBIP
CBIP is a true examination-based certification program designed to offer a meaningful and valuable credential. CBIP is founded on the following principles: • • • • • • • •

An Overview of CBIP
The CBIP Exams What You Do CBIP APPLICATION
Every CBIP applicant must complete a CBIP application form. The application form is available for download on the CBIP Web site (www.cbipro.com) and may be submitted to TDWI at any time. It is reviewed for completeness and kept on file until the examination time. An application must be completed before taking the exams.
TAKE EXAMS
The table on the facing page illustrates the exams that are required for each CBIP specialty. Every specialty requires three exams – the IT Core Exam, the Data Warehousing Exam, and one exam unique to the specialty. The self-inventory completed earlier will prove helpful in choosing those specialties and exams where you have the highest probability of success. All exams are taken in a controlled and proctored environment. In addition to group examination opportunities (such as may be offered after this class) TDWI can arrange examination sessions to meet your timing and location needs.
RECERTIFY
Recertification is necessary to maintain current knowledge and skills in the changing fields of business intelligence and data warehousing. A CBIP credential is valid for a period of three years from the issue date and must be renewed prior to expiration and during each subsequent 3 year period. Various types of professional development may be used to satisfy the renewal requirements: self-study, retaking exams, taking continuing education courses within your specialty area, and participating in education programs by designing or teaching courses. Full or partial renewal credit can be earned by adding additional specialties to a CBIP certificate. Credit may also be earned by submitting questions for possible inclusion in CBIP related material. 120 contact hours of appropriate activities must be documented during the three-year period to renew your certification.
PAY FEES
There is a fee associated with every exam that is taken. Fee payment is required at the time of examination unless other payment arrangements have been agreed upon prior to the exam session. Additionally, there is an annual recertification fee. Fees are not printed here because occasional price changes would make this book inaccurate.

An Overview of CBIP
Exam Description Body of Knowledge Based DEFINITION
Each of the exams in the CBIP program is based upon a specific Body of Knowledge (BOK) that includes concepts, principles, processes, applications, and best practices used in each of the areas. Using the BOK, a three tier outline was created to provide a detailed and standardized structure for the Body of Knowledge.
USING THE BODY OF KNOWLEDGE
A detailed outline for each exam is available in the CBIP Examinations Guide, which will be provided to you. To prepare for testing, it is recommended that you review the exam outline and 1) check off those items where you have sufficient knowledge and experience 2) highlight those items or groups of items where you don't have the depth of understanding to apply your knowledge and experience 3) use research tools such as the internet or industry publications to expand your knowledge 4) use resources such as others in IT to discuss concepts and principles and their application
LEVELS OF KNOWLEDGE
Each of the questions in the exam tests against different levels of knowledge and ability to apply that knowledge: • • • • •
© The Data Warehousing Institute
Recognition: The ability to name a concept, fact, or idea and recall information about it. Discrimination: The ability to distinguish between similar concepts, ideas, and facts. Understanding: The ability to know what a concept, fact, or idea means in sufficient depth to describe what it does and does not include. Applications: The ability to use concepts, facts, and ideas in a variety of situations and to include them when creating solutions to business or information systems needs. Evaluation: The ability to assess the quality of a system, product, or solution on the basis of related concepts, ideas, and facts.

Testing Techniques Exam Strategy MANAGING YOUR TIME
Each exam contains 110 questions and you are 90 minutes to complete it. While taking the exam you will find the number of unanswered questions in the bottom right hand corner. Included in each exam are 10 questions which are being used for evaluation purposes. These questions will not be identified so if you encounter any oddly questions assume they are part of the evaluation set and move on with your testing. Don't waste time worrying about individual questions.
EXAM FORMAT
The exams use straight line testing which means that each question is completely independent of the others, and incorrectly answering a question does not affect which upcoming questions are displayed.
YOUR STYLE OF TESTING
If you are out of practice taking exams, you should consider these strategies which have proved to be effective for others. Changing answers: Everyone has their own thoughts as to whether it's effective to change an answer. Sometimes going through an exam will reveal answers to other questions. If you feel strongly that the answer should be changed then do so - otherwise you will waste time thinking about it. Skipping questions: When you are testing, the check mark in the top center of your screen will not turn red until you have answered each of the questions. Once you run out of time, the check mark will turn red whether or not you have answered all the questions. Keeping notes: You will be provided with several pieces of blank paper for note taking. Going back if you have time: You will receive a 5 minute and a 15 minute warning so you can allocate time to review the questions if you so wish.

TDWI Exam Preparation for CBIP
An Overview of CBIP
Testing Techniques Question Strategy NEGATIVES
These types of questions contain 'No', 'Not', and 'Except', and require a different thought process. Pay particular attention to each of the potential answers and remember that you are looking for true statements.
ABSOLUTES
When a question contains words such as 'every', 'always', 'none', and 'only' it should be carefully reviewed since it means that all parts of the answer cannot be disputed.
GUESSING
There are no penalties for guessing so it is better to take a good guess than to leave a question blank.
EASY VS DIFFICULT QUESTIONS
Some of the questions are going to be easy but even if this is the case, answer each BEFORE you review the possible answers. Don't skim over any of the answers since some may be more correct than others. Sometimes the question is just easy and quickly answering it will give you extra time on the more difficult questions.
READING VS MISREADING
There are two strategies for dealing with questions where an immediate answer doesn't seem apparent; the true/false test and parsing the question and answers. True/Fast Test: You will be provided with scratch paper so starting with the first answer write down a 'T' or 'F'. Go through the same process for each of the answers. Then review the results and pick the best answer which may or may not appear to be the complete correct one. You need to pick the best choice amongst the alternatives. Parsing the question and possible answers: If the answer doesn't seem obvious try parsing into different phrases.

EVALUATION METRICS Teaching and Presentation Skills. How well does the instructor explain and illustrate difficult concepts? Does the instructor organize and present information in a logical way that facilitates comprehension? Does the instructor use exercises, handouts, or audio/visual displays to illustrate or reinforce concepts? Course Content. Does the content taught by the instructor match the course description? Does the course offer relevant content at the appropriate level? Does the course material flow logically from topic to topic? Does the course provide information that is or will be relevant to your job? Class Management Skills. How well does the instructor handle questions from the audience? Does the instructor maintain a reasonable pace for the content and stick to the schedule? How well does the instructor deal with unforeseen problems with A/V, temperature, lighting, and so on? Course Book and Handouts. Is the course book a valuable reference tool, or merely a set of PowerPoint slides? Does the instructor jam too much on a single slide? Are the graphics legible? Does the instructor make extensive use of the Notes section to annotate the slides or provide additional, relevant information? Objectivity. Does the instructor show a bias toward any product or solution? Is the instructor a credible source of reliable information about products, trends, and issues? Does the instructor inappropriately sell himself/herself or company as a potential service provider? Does the instructor collect business cards or conduct raffles during class time for marketing purposes?
