(1) SCL(Supply Chain Logistics)
A TOC expert certification in Supply Chain Logistics certifies that the individual has sufficient knowledge and tools (capability) to successfully implement both the Operations (Drum-Buffer-Rope and Buffer Management) and Distribution solutions of TOC. The Supply Chain Logistics expert exam is divided into two parts. The total examination time is 8 hours. Typically, the exam is divided into two four-hour parts. A passing grade for certification is 70% correct for both parts of the exam overall. The expert exam consists of a mixture of objective and open-ended (i.e. essay) questions. Some of the exam questions will focus on one or more case studies presented in the exam. The exam overall addresses the three main topics described below.

(4) Thinking Process
This is an eight-hour exam focused on a Thinking Process analysis of a case study.
The Thinking Process Exam Expectations
The applicant should have experience at the Jonah-Jonah level (meaning to have the ability to teach the thinking process effectively to others–the applicant does not have to be a certified Jonah-Jonah) and have applied the Thinking Processes on many topics over a period of time.
The applicant has already proved general knowledge of TOC concepts as evidenced by passing the Fundamentals Exam.
The Thinking Process Exam goes well beyond the Thinking Process questions on the Fundamentals Exam which focused on: Knowledge, Comprehension and Basic Application. The Thinking Process Exam focuses on: Analysis (breakdown of information), Synthesis (putting facts together) and Evaluation (judgment of solutions).
The case study in the exam is significantly longer than the Thinking Processes cases in the Fundamentals exam. The case is complex enough to require significant Thinking Process skills, yet simple enough to be able to be solved during the limited exam period. The case represents an environment common to most parts of the world. It does not require any specific subject matter skill nor extensive knowledge of any particular solution. However, knowledge of TOC concepts is always helpful.
The applicant will demonstrate competency in all five Thinking Process Tools: Current Reality Tree, Evaporating Cloud, Future Reality Tree, PreRequisite Tree and Transition Tree.
Because of the limited time to take the exam, a full, detailed Thinking Process analysis of the case is not possible. The applicant will be tested on several elements of the analysis representing each of the Thinking Process Tools and on creating a partial Current Reality Tree, a partial Future Reality Tree, a partial PreRequisite Tree and a partial Transition Tree.
The exam will be graded upon the applicant’s clear, effective, and logical application of the Thinking Process Tools consistent with the elements of the case. Grader has a full solution to the case as well as samples of ‘excellent’, ‘good’ and ‘poor’ responses for each question on the exam. The applicant does NOT need to provide the exact, same solution to the questions. Rather, the applicant must show proficient use of the Thinking Process Tools and the Categories of Legitimate Reservation. Most questions require the creation of cause – effect diagrams.
Thinking Process Exam Contents
The exam contains questions totaling 100 points. The questions range from 2 points to 15 points each.
A typical exam contains the following structure and question types:
Initial Narrative-The case background providing the relevant current state.
Question (10 Points)-Creating an Evaporating Cloud on a minor issue in the Case.
Question (3 Points)-Correcting a illogical cause – effect branch into a logical cause – effect branch.
Question (2 Points)-Seeking to resolve cause insufficiency reservation in a partial logic branch.
Question (3 Points)-Seeking to identify causality for an effect based on the Case.
Question (10 Points)-Evaluating and correcting a given Evaporating Cloud.
Question (4 Points)-Improving upon an implied (partial) Feedback Loop drawn from the Case.
Question (4 Points)-Demonstrating the logical extension (further effects) of an entity in the Case.

Additional Narrative-Additional case background or added information helpful in finding a direction for the future.
Question (5 Points)-Creating the Desired Effects from the given UnDesirable Effects.
Question (10 Points)-Creating a Negative Branch Reservation from a suggested Injection.
Question (4 Points)-Writing a paragraph about other areas needed in the solution.
