A: Work demonstrates clear understanding of the material under study, but also a superior ability to utilize that material in the assignment. All criteria are met. Work goes beyond the task and contains additional or outstanding features. B: Work demonstrates a good understanding of the material under study, and utilizes the material well in the assignment. The student meets the assignment criteria, with few errors or omissions. C: Work minimally demonstrates a basic or technical understanding of the material under study, and uses some relevant material in the assignment. Work may not address one or more criteria or may not accomplish what was asked. F: Work that is incomplete, inappropriate and/or shows little or no comprehension of the material under study. 7. Guidelines for Submitting Assignments. Completed assignments and exam files will be uploaded to Canvas. Your grade will be based upon (1) how well you conduct your analysis and (2) how professionally you communicate your results and ideas. Submit your assignments as one MS Word or PDF document and one Excel workbook showing the steps of your analysis. The report should summarize the analysis of each problem or project part including a brief overview of the task at hand. Reference in the body of your report the attached Excel workbook. Worksheets should be organized and annotated to readily communicate your results. Demonstrate clearly that you understand the principles and techniques being studied. Conclusions of the analysis should be explicitly stated. Briefly state the implications of your analysis and answer any questions asked in the statement of the problem. 8. Exams. Exams will be given at the dates and times listed in the above schedule. The Management Science exam is given in two parts: Part 1 is a 60-minute online quiz to be completed in class; Part 2 is a take home section to be submitted by the date above. The Statistics exam is given as a 3-hour in-class exam. Exams are open note, open book, open laptop, but no communication of any kind is allowed, either verbal, written, or electronic except with the instructor. Cell phones must be turned off and stowed away. You must notify the instructor at least 1 week prior if if you have a conflict for either exam. Documented proof may be requested. For legitimate conflicts, a make-up exam may be scheduled. Requests to correct grading errors must be made within one week of grades being returned. 9. Optimization & Simulation Problem Sets. Details of the optimization and simulation problem sets are provided in Canvas. You may work in 2-member teams for the problem sets, but all students should individually attempt and comprehend all of the problems. Each team will submit one report (MS Word or PDF) and one Excel workbook by the due date. Problem set reports should include clear answers to each of the questions listed. Reference in the report any work completed in an attached Excel file. MBA701, Spring 2015 Syllabus P age |4 10. Stock Project details are provided on Canvas. You will select a company and analyze the performance of its common stock during the recent past. You may consult with others, but each student must analyze a different stock and submit an individual assignment. Each student will submit one report (MS Word or PDF) and one Excel workbook by the due date. Project reports should begin with an executive summary of the key issues of the project, your methodology, and your recommendations. Describe your assumptions, methods, and answers to any project questions in the body of the report. Reference in the report any work completed in an attached Excel file. 11. Online Tutorial Post-Tests: Two online tutorials must be completed as graded assignments: 1) Spreadsheet Modeling Online Course: Excel 2013 (or 2007); and 2) Quantitative Methods Online Course. Both courses are available from Harvard Business Publishing and can be accessed via course pack hyperlink available on Canvas. You are expected to complete the tutorials individually. You may complete the tutorials at your own pace. The assessments are not timed, but the results for the assessments must be submitted by the respective due dates. You may refer to the tutorials and other notes while completing the assessments but you are not to consult with others. Contact the instructor if you encounter technical issues regarding the online tutorials. 12. Case Report assignments are posted on Canvas and must be submitted by the respective due dates above. You may work in 3-member teams for the case project reports, but all students should be individually prepared to discuss the case in class. Each team will submit one report (MS Word or PDF) and one Excel workbook by the due date. Case reports should begin with an executive summary of the key issues of the case, your methodology, and your recommendations. Describe your assumptions, methods, and answers to any case questions in the body of the report. Reference in the report any work completed in an attached Excel file. Self-evaluation and peer evaluations for case assignments will be required and an individual’s grade may be penalized if there is sufficient evidence he/she has not taken acceptable responsibility for the assignment or does not complete the evaluation. Case teams should discuss expectations at the beginning of the semester. All team members should take responsibility for making sure all parts of the assignment meet the agreed expectations. 13. Case Discussion and Class Participation includes being prepared for class, being involved in class discussion, and being engaged with the material outside of class. You are expected to be thoroughly prepared to discuss assigned readings and cases. You may be called upon at any time to share your perspective, work with other students, or respond to a question. You are encouraged to attend office hours and email the instructor with questions and insights. Participation is essential because: 1) discussion about a business situation is most fruitful with multiple perspectives; 2) articulating your thoughts and questions demands that you be clear and precise; 3) it promotes critical thinking and maximizes your learning efficiency. Effective communication and participation are vital business skills in any organization. Participation in case discussion is an important part of your grade. The instructor assigns case discussion grades based on the quantity and quality of your participation. The quality of MBA701, Spring 2015 Syllabus P age |5 participation is measured by how well you explain your own critical analysis, contribute original ideas, make comparisons based on outside experience or readings, offer critical questions for the class to consider, respond to questions raised by others, and offer feedback to your teammates. If you plan to miss a case discussion, please notify the instructor one week in advance so that an appropriate make-up assignment may be issued. 14. UNCG Academic Integrity Policy. You are expected to be familiar with and abide by the UNCG Academic Integrity Policy. The Policy may be found at: http://sa.uncg.edu/handbook/academic-integrity-policy/ On team assignments, each individual team members must take responsibility for all parts of the assignment or face a potential penalty. On individual assignments, you are not to share details of your work including computer files or printed output from your computer analysis. Prohibited actions also include working together side-by-side on separate computers. Specifically, on exams you are not to communicate with others in any way or share any of the exam materials with others. Violations of the Code will result in penalties ranging from an F on the assignment to an F in the course. 15. Bryan School Faculty Student Guidelines. The Bryan School faculty has approved a set of guidelines for the conduct of classes. They can be found at the following link http://bae.uncg.edu/wp-content/uploads/2012/08/faculty_student_guidelines.pdf Be professional. Have integrity. Treat the classroom like a business meeting.
