The tools practiced in this workshop are: • Descriptive statistics • Histograms NOTE: Complete the Histogram and descriptive statistics in MS Excel and cut and paste the results into this document. Submit the MS Word Workshop 2 into the Dropbox in Week 4 module. Situation: Consider that you are interning for a prominent attorney in Houston. You are working on a project to reduce the client intake process time. This data is needed to establish a baseline measurement at the beginning of your Lean Six Sigma project so that you will have a measurement to compare against later once the process has been improved. NOTE: The raw data that you will use is at the bottom of this workshop. Instructions: Use information from your training manual in Measure Phase - Lessons 9-11 to assist you with the activities that follow. Be sure to follow the "best practices for each tool you use in this workshop. To create a baseline measurement, you have collected a random sample of times for the client intake process (data is at the bottom of this Workshop). You recorded your time measurements in a table (see the data at the end of this Workshop). Use Microsoft Excel to calculate your descriptive statistics, create a histogram of your data, and provide answers to the questions below. Activities: (also see next page) 1. For the client intake process times, what is the a. Mean time in hours? b. Standard deviation in hours? c. Minimum in hours? d. Maximum in hours? e. Range in hours? 2. Create a histogram that summarizes your data set (i.e., client intake process time). 3. Near the end of your Lean Six Sigma project, after you have implemented solutions to improve your client intake process, you measure the process performance again and get the following results: Intake process time - Mean: 235 hours; standard deviation: 45 hours; minimum: 100 hours - Maximum - 300 hours. a. Have you improved the process? Yes or no and why. Hint: Perform a before and after comparison by comparing the baseline measurements in Activity #la-e of this Workshop with the measurements given in this question. The firm partners' specifications for the client intake process cycle time are: Target: 200 hours + 75 hours (lower specification limit: 125 hours and upper specification limit: 275 hours) b. How well does the improved process fulfill customer requirements/specifications? Hint: Perform another comparison by comparing the measurements given in this question to the customer specifications given in the "Situation" part of this Workshop.
