However, no presentation or exams are required. A pass/fail grade will be given.  

2. First-Year Research Paper

It is the student’s responsibility to find a faculty mentor, who will guide the student to work on his/her first-year paper. The student is encouraged to do so as early as possible and s/he should inform the Area Ph.D. Advisor no later than February 1st (i) the name of the faculty mentor and (ii) the topic of first-year paper. The student is expected to have at least bi-weekly meetings with the faculty mentor to discuss his/her research progress. The student should register with the faculty mentor in MGMT69900 Research PhD Thesis in the summer. 

3. First-year Evaluation

The evaluation of a first-year student consists of four parts.

a. Core Methodology Courses

The student is expected to maintain a minimum average grade point of 3.2 each semester. A student failing to meet this requirement should take relevant courses under the approval of the Area Ph.D. Advisor within one year to make up for the low grades. If the grade achieved by retaking the course is higher than the initial grade, the second grade will be substituted for the first in computing the student's grade point average for the purpose of satisfying the research-methods grade requirement. If a student does not achieve the minimum 3.2 grade-point average, the student will be dropped from the program.

b. Written First-Year Exam

During the first year, after satisfying each of the above core course requirements, the student must take a written exam.
i. The exam will take place during the second to third week of May. 
ii. The exam covers material from Linear Optimization, Stochastic Processes, and Microeconomics.
iii. An exam committee consisting of three faculty members will set the exam questions, typically one problem for each area.
iv. The exam is in-class and open book. 

c. First-Year Paper

The student is expected to complete the first-year paper by the end of the summer.
i. The paper must consist of a clear introduction that states the importance of the problem, an extensive literature review that articulates the contribution of the work, a concise description of the model, and somewhat complete analysis of the model. Although students may seek and receive guidance from faculty, it is expected that students will assume leadership and primary responsibility in defining the problem and writing the paper.  The paper may not be complete and ready to submit, but it should clearly demonstrate the student’s potential of completing quality research that would lead to publication in a top-tier journal.
ii. The student should present his/her first-year paper to the entire OM faculty before the third week of September in their second year. The student should provide the paper to all OM faculty at least one week before the presentation. The presentation should clearly demonstrate the student’s mastery of the field s/he is working on and understanding of the problem, methodology and results.

d. Graduate Assistantship

The student is expected to perform TA/RA duty depending on the assignment from the faculty. The faculty will provide written feedback on student’s performance at the end of each semester. The OM faculty may decide to suspend the financial support to a student, if the student fails to meet the expected performance for TA/RA duty.

e. Feedback

The OM faculty will meet to discuss the student’s performance in the first-year exam and first-year paper.  The feedback will be communicated to the student individually by the Area Ph.D. Advisor.
i. If a student’s performance in the written exam is not satisfactory, the student will be given a second chance to retake the exam before November 1st of the year.
ii. If a student’s first-year paper does not meet the expectation, the student will be given until December 1st to improve the paper and present to the OM faculty.
iii. A student will be asked to leave the program if s/he fails to perform satisfactorily in the second time. In this case, the student can stay until the end of spring semester of his/her second year to obtain a MS degree in Global Supply Chain Management, provided that s/he can complete required coursework for the degree by then.

Students with previous work experience in a managerial capacity or who have already taken such a course elsewhere may petition the Area Ph.D. Adviser to waive this requirement.

e. Coursework Evaluation

The student is expected to maintain a minimum average grade point of 3.2 each semester. A student who fails to meet this requirement should take relevant courses under the approval of the Area Ph.D. Advisor within one year to make up for the low grades. If the grade achieved by retaking the course is higher than the initial grade, the second grade will be substituted for the first in computing the student's grade point average for the purpose of satisfying the research-methods grade requirement. If a student does not achieve the minimum 3.2 grade-point average, the student will be dropped from the program.

f. Graduate Assistantship

The student is expected to perform TA/RA duty depending on the assignment from the faculty. The faculty will provide written feedback on student’s performance at the end of each semester. The OM faculty may decide to suspend the financial support to a student, if the student fails to meet the expected performance for TA/RA duty.

5. Preliminary Exam

This exam consists of a written and an oral part as described below:

a. Plan of Study

Students are required to submit a formal plan of study (POS) to the Purdue Graduate School by the end of the spring semester of their second year in the doctoral program, and prior to taking the preliminary examination. If a student enters the program without equivalent course work at the MBA level and must take core courses, this requirement may be delayed until the start of the student's third year of enrollment.
To submit a plan of study (POS), a student must (i) form a POS committee composed of the student's major professor and a minimum of two other qualified faculty members who will supervise the student's dissertation research, (ii) complete a POS that includes a list of required courses for the PhD degree with the help from his/her Major Professor and the other POS committee members (forms can be obtained from the PhD advising office), (iii) have the POS approved by the POS committee, and (iv) file the POS with the PhD advising office. If there are changes in the list of courses or committee membership after the plan is approved in the Graduate School, the student must submit for approval any revisions.

b. Written Exam

Before the end of the first week of April the student will select two topics from MGMT690 Operations & Supply Chain Analysis courses, and inform the Area Ph.D. Advisor of their selection.  The student will be given a reading list of 3-4 papers on each topic to prepare the exam before the end of the third week of April.  During the second to third week of May, the student will be tested on their selected topics. This is an in-class open book exam.

c. Research Paper

This paper must be submitted to the Area Ph.D. Advisor by August 31st of the student’s third year in the Program. The paper should be in a stage that is close to be submitted for publication. This paper may be an extension of the first year summer paper.

d. Oral Exam

The oral part of the preliminary examination will take place during the first--second  week of September, and it consists of a presentation to the OM faculty of the student’s research paper followed by questions on issues covered by the paper as well as questions related to student’s research.

e. Feedback

The OM faculty will meet to discuss the student’s performance in the preliminary exam.  The feedback will be communicated to the student individually by the Area Ph.D. Advisor.
i. If a student’s performance in written the exam is not satisfactory, the student will be given a second chance to retake the exam before November 1st of the year.
ii. If a student’s oral exam does not meet the expectation, the student will be given until December 1st to improve the paper and present to the OM faculty.
iii. A student will be asked to leave the program if s/he fails to perform satisfactorily in the second time. In this case, the student can stay until the end of spring semester of his/her third year to obtain a MS degree in Global Supply Chain Management, provided that s/he can complete required coursework for the degree by then. 

6. Admission to Candidacy

Upon completion of the requirements listed above, the student will enter candidacy. A qualified student must form the dissertation committee within 1 month after being informed that s/he passes the preliminary exam. In keeping with Graduate School requirements, the dissertation committee shall consist of at least 4 members. The chairperson or at least one of the co-chairs must be from the student's major area. At least 3 members must be from the Krannert graduate faculty. It is the student's right to choose and alter the composition of the dissertation committee. However, it is the right of the faculty to decline any student's invitation to serve as a dissertation committee member or chair.

7. Third and Four Year Requirement

a. Required Seminar Courses

The student is expected to register MGMT 69100 OM Seminar & Brown Bag Series (2 Credit Hours) and MGMT 690000 Doctoral Topics in OM I or II (1 Credit Hour) each semester.  The expectation for third or fourth year student is to present his/her research work to OM faculty every semester to demonstrate satisfactory research progress toward dissertation. They should also actively participate in discussions and demonstrate their understanding on the topics discussed. A letter grade will be given. 

b. Other coursework

The student may take additional graduate level courses that would help in their research. The course selection must be approved by Faculty Advisor.

c. Research

The student should work with Faculty Advisor toward their dissertation by registering MGMT69900 Research PhD Thesis. The student must demonstrate satisfactory progress in research in each semester.

d. Teaching

The student is expected to teach an undergraduate operations course in the summer of their third year. An international student must be certified to teach through ENGL 620 before teaching. The Faculty Advisor will mentor the student throughout his teaching assignment. It is the student’s responsibility to meet and report to the Faculty Advisor on his teaching performance on a regular basis. A student is highly encouraged to attend a faculty-taught section of MGMT361 Operations Management prior to teaching.

e. Graduate Assistantship

The student is expected to perform TA/RA duty depending on the assignment from the faculty. The faculty will provide written feedback on student’s performance at the end of each semester. The OM faculty may decide to suspend the financial support to a student, if the student fails to meet the expected performance for TA/RA duty.

f. Evaluation

At the end of each semester, the OM faculty will meet and discuss the progress of the student toward his/her dissertation. The Faculty Advisor will communicate to the feedback to the student. A student who shows unsatisfactory performance will receive a formal letter from the Area Ph.D. Advisor with suggested remedial actions. A student will be dropped from the program if showing unsatisfactory performance in two consecutive semesters.

8. Dissertation Proposal

Within 12 months after passing the preliminary examination, a student must formally present, and defend, a dissertation research proposal to his or her formal dissertation committee. The doctoral dissertation proposal presentation is open to other faculty and to Ph.D. students. To be accepted, a student's research proposal is expected to represent substantial progress toward completion of a doctoral thesis along with a statement of further work to be performed. Once a student's research proposal is accepted by his or her advisory committee, it is to be considered a "contract" which will guide the student through the final preparation of his or her dissertation. If the research proposal is not accepted by the dissertation committee, the student may be given the opportunity to make a second attempt. However, significant delay in achieving an acceptable proposal may be cause for withdrawal from the program.


9. Dissertation

For the dissertation, students are expected to demonstrate competence and ability to conduct research as an independent scholar. Also, the dissertation is expected to be a research effort that makes a contribution to the body of knowledge it addresses. During the conduct of the dissertation, students are encouraged to consult their doctoral dissertation committee frequently. It is the student's responsibility to keep the committee informed at all stages.
A student's public defense of his or her dissertation is required. Note that any major concerns committee members may have about the dissertation are expected to be resolved before the public defense of the dissertation is scheduled. The following procedures hold for the dissertation defense and need to be followed:

a. The dissertation must be approved by the dissertation chairperson before it is submitted to the final examining committee. Each member of the dissertation committee shall receive a copy of the dissertation at least two weeks before the date of the final examination.
b. Written notice of the dissertation defense shall be given to Krannert faculty and students at least two weeks prior to the defense.
c. Copies of the dissertation abstract shall be circulated along with a written defense announcement.
d. The defense will be conducted by the dissertation committee under the guidance of the dissertation chairperson. The defense format should allow for adequate presentation of the research work and sufficient time for questions and answers by the committee and others present. The format should also include a time when the public is excused so that the dissertation committee may ask further questions of the candidate or deliberate among themselves.
e. In keeping with Graduate School regulations, only the dissertation advisory committee has the authority to vote for or against the acceptance of the dissertation. These regulations also state the decision rule to be used in determining the final outcome of the defense. Currently, for example, there may be a maximum of one dissenting vote in a successful defense of a dissertation.
Students are cautioned to familiarize themselves with the full set of School and University regulations regarding dissertation format and procedures. It is the student's responsibility to ensure that they comply with these regulations. A student must register as a degree candidate (CAND 991) in the semester s/he plans to graduate.

10. Fifth-Year Financial Support

We expect a student to complete his/her program requirement by the end of the fourth year. Financial support is not guaranteed in the case when a student needs to extend his/her study to the fifth year. Under special circumstances where a student demonstrates very good performance but needs to continue study in fifth year, the student can apply for fifth-year funding before February 1 of their fourth year. If the application is approved, the student will obtain funding by teaching in the summer of their fourth year.
