Work system design:
1__Job design- Technical (able to do it), Economic (value must be added), Behavioral (feels good about doing it) Feasibilities
Labor specialization- higher specialization = narrow scope of expertise, usually more boring Eliminating boredom- Enlargement (more tasks, horizontal expansion), Job Enrichment (vertical expansion, schedule own work, test own output), Rotation (expose to other jobs) Team Approach- Problem solving teams (small group with operational expertise, ID analyze and solve), Special Purpose task forces (Issues of major significance, cross functional team, when assignment is done team is over), Self Directed team (team defines goals) Self Managed team (source outside of a team defines goals) Methods analysis- Figure out what to analyze(quality/productivity issues,), communicate with workers, watch and try to figure new way to do it. OSHA- occupational safety and health act to assure workers have good conditions, working conditions effect productivity, output quality, and saftey

2__Work measurements – how long should it take to do a job? Time Studies (Manufacturing)- Steps: 1. Chose specific job to be studies 2. Tell the worker who you are studying 3. Break job into recognizable units 4. Calculate the number of cycles you must observe by using sample data n=[(z/a)(s/x)]2 (n=# of observations, z= # of std dev at desired confidence, a=desired accuracy, s=std dev from sample, x=mean from sample) 5. Time each element, record times and rate worker performance 6. Compute Normal Time [NT= Mean Observed Time (MOT) * (PRF) * (F)] 7. Compute Standard Time (ST= NT * allowance factor) (AFtime worked = 1/1-PFD or AFjob=1*PFD) (Performance Rating Factor- factor of above or below 1, 1 being average performance) (Frequency of Occurrence- how many times each element occurs, if done every cycle > 1) (PFD - Workers pace…...

You suspect the company of falsely advertising the benefits of taking their pills. Suppose you take a sample of 100 product users and find that only 5% have lost at least 10 pounds. Is this enough to prove your claim? What about if 72% had lost at least 10 pounds? Goal: 9.1 Elements of a Hypothesis Test 1. Assumptions 2.

State the null and alternative hypotheses for the diet pill example. 3. Test Statistic Definition: Test Statistic A test statistic is a measure of how compatible the data is with the null hypothesis. The larger the test statistic, the less compatible the data is with the null hypothesis. Most test statistics we will see have the following form: What does a large value of |T | reflect?

Some new machinery is being evaluated with the aim of increasing the daily mean yield without changing the population standard deviation σ. Hypothesis Testing: Evaluating the effectiveness of new machinery at the Bloggs Chemical Plant Null hypotheses • The claim tested by a statistical test is called the null hypothesis. The test is designed to assess the strength of the evidence against the null hypothesis. Usually the null hypothesis is a statement of “no effect” or “no difference”, that is, a statement of the status quo. Alternative hypotheses • The claim about the population that we are trying to find evidence for is the alternative hypothesis. The alternative hypothesis is one-sided if it states that a parameter is larger than or...

Project There will be a team-based Project. Details of this project will be provided early in this semester. Determination of Course Grades The evaluation of coursework will be based on the student’s performance on: * Homework 15% * In Class Activities and Participation 10% * Midterm Exams 30% * Final Exam (cumulative) 30% * Data analysis project 15% Academic Honesty At this point in the program, you must have become very familiar with the graduate student honor code. The Code appears in the Graduate Business Programs Catalog and Student Guide. Every student is expected to act in accordance with the honor code. To the extent violations of the code are detected, such as plagiarism, cheating on an exam, collaboration with others on individual work, or freeloading on team projects, consequences will be very detrimental for your grade in this course, and potentially, for the remainder of your career.

...technologies, can be employed either for social good or evil. The professionalism encouraged by these guidelines is predicated on their use in socially responsible pursuits by morally responsible societies, governments, and employers. Where the end purpose of a statistical application is itself morally reprehensible, statistical professionalism ceases to have ethical worth. C. Shared Values Because society depends on sound statistical practice, all practitioners of statistics, whatever their training and occupation, have social obligations to perform their work in a professional, competent, and ethical manner. This document is directed to those whose primary occupation is statistics. Still, the principles expressed here should also guide the statistical work of professionals in all other disciplines that use statistical methods. All statistical practitioners are obliged to conduct their professional activities with responsible attention to the following: 1. The social value of their work and the consequences of how well or poorly it is performed. This includes respect for the life, liberty, dignity, and property of other people. 2. The avoidance of any tendency to slant statistical work toward predetermined outcomes. (It is acceptable to advocate a position; it is not acceptable to misapply statistical methods in doing so.) 3.
