Some of the topics include regression, forecasting, risk analysis, simulation, linear programming, data mining, and decision analysis. This course provides students with the fundamental concepts and knowledge needed to understand the emerging role of business analytics in organizations and shows students how to apply essential tools in a spreadsheet environment. Emphasis is on business applications, concept development and effective interpretation of models and results, rather than theory and calculations. Students use a computer software package for data analysis. Learning Objectives Identify problems, define objectives, analyze information, and evaluate risks and alternatives to enable qualitative and quantitative methods to solve business problems Select and apply appropriate data analysis tools with the support of software in a variety of business scenarios. Understand data gathering and input considerations in model building, validation and testing Be able to analyze and interpret output (graphs, tables, mathematical models, numerical indicators of performance, etc.) and know how to report results in a fair, objective and unbiased manner. Class Format and Policies This course is organized around the Course Schedule (see below) which provides a map of requirements for assignments and corresponding due dates. Each week, closely follow the schedule and complete the requirements as indicated. Course files, such as PowerPoint presentation slides and Excel files referred to in the schedule are posted in Canvas within the respective chapters. 1

2 The Schedule was prepared so you can plan your work accordingly. Pay attention to due dates. It is essential that you dedicate enough time to complete all the required assignments. In general, you should be able to solve the graded assignments (called Projects) after reading the indicated material, following the class lecture and discussion, and solving selected end of chapter problems. Pay attention that these selected problems (referred to as Applications in the course schedule) are already solved (see Required Course Materials section below) but you should try to work on them before looking at the solution. In doing so you will be developing important skills in business analytics and addressing your assignments for grading as well. Should you have problems in solving the assignments or understanding the material, you may discuss the problems in class, contact the instructor via or within Canvas, via phone, or see the instructor in his office. If you are contacting the instructor by , a few items will help expedite solving the question: a) Describe the issue/question you have as clearly as possible. If there are multiple parts, breakdown the question in multiple parts. Those will be addressed one by one. b) Attach a draft of the work you have done for review. c) Submit your analysis or questions to the instructor with sufficient time for review and feedback. Assignments Business Analytics involves "learning by doing" assignments. That is, the course and assignments have been designed so you can learn essential skills and concepts from carefully selected applications used in the practice of business analytics. By solving these assignments you will also develop an understanding of widespread issues encountered by the professional in this area. Graded assignments are called Projects which you are required to complete on or before the due date. There are 7 Projects and they involve the analysis of problems and/or cases from the textbook. The analysis for all assignments will be done using Microsoft Excel with the assistance of Frontline Systems Risk Solver Platform and XLMiner. In addition, there are three exams in the course on the dates indicated in the syllabus. You will need a personal copy installed in your personal computer which can be downloaded from Frontline Systems website. See required Course Material below. Pay attention to the organization and quality of your work file which may reduce your overall grade. NO LATE ASSIGNMENT WILL BE ACCEPTED. It is your responsibility to submit the document on or before the due date. Grades When preparing your assignments pay attention to the content, cleanliness, and organization of the document. They all contribute to your grade. The final grade is computed as a percentage of the total points earned in 7 projects (56 percent) and the 2

3 three exams (42 percent). Assignment 1 is worth 2 percent, however, it is a mandatory assignment, and failure to complete assignment 1 will lead to a further loss of 10 points on the first exam. Assignment 1 is about course expectations. Based on what you have learned from the Syllabus, log on to Canvas and answer the following questions in a short paragraph: What do you hope to gain from this course? Is there a topic you would like to know more about? Assignment 1 is mandatory and must be completed by all students. As noted, failure to complete assignment 1 will lead to a loss of 10 points on your first exam. Letter grades will be assigned based on the following criteria as a percentage of total points: 92 and above: A 90 to less than 92: A- 87 to less than 90: B+ 82 to less than 87: B 80 to less than 82: B- 75 to less than 80: C+ 70 to less than 75: C Below 70: F Incomplete will be given by exception when a limited portion of the course material has not been completed by the last exam due date, in accordance with University policy published in the Catalog. The instructor on an individual basis will review each case. Required Course Material: 1. Textbook: Essentials of Business Analytics, 1st Edition 3

Follow these instructions to download and install Frontline System s Risk Solver Platform and XLMiner (student version) IMPORTANT NOTES!!!: DO NOT register as Students on This URL is intended for large companies. Most mistakes occur when students do not have or fail to enter the Course Code and Textbook Code (given below). This results in confusion and lost time, which you can mitigate or avoid by following the proper sequence of instructions below. Students must register, download, run SolverSetup, and enter a password and license activation code. The password and activation code are sent to you by . This is all very simple to do, if you read and follow the instructions. Yet when courses are starting up, the software company is handling hundreds of support tickets per day, repairing situations for students who just haven t read the instructions, or have read them, but decided to do something else. This will delay your start and impact your performance in the course. The instructor is not responsible for the proper setup of the software. Make sure you follow these instructions correctly and in advance of the start of the course. The software DOES NOT run under any Excel version for Mac. There is a commercial Premium Solver Platform for Mac, but the company does NOT offer it for academic or textbook use, and it will NOT support students attempting to use it (unless they buy a license for $2,000). Preparation: 1. If you have a Mac, visit and read To use the software for this course, you ll need to install Windows alongside Mac OSX, and install Excel or Office for Windows. This will also allow you to use other Windows software, as well as Mac software on your machine. 4
