2  2012 American Society for Quality. All Rights Reserved. Page Week One Review –ABI Black Belt v1.1 Last Time We … Defined our project Leaned our processes Learned statistical techniques Validated our measurement system Created standard work Conducted hypothesis tests Practiced coaching Green Belts Let’s do a quick review before starting the new material.

4  2012 American Society for Quality. All Rights Reserved. Page Week One Review –ABI Black Belt v1.1 Lean Defined A philosophy and set of methods where waste is identified continuously and eliminated passionately. A complete lean system should have:  Techniques/Tools  Management (mindset and accountability)  Organizational Environment (skills, culture, and behaviors) Waste is any activity (or inactivity) that consumes resources and do not add value to the customer through the product or service.

5  2012 American Society for Quality. All Rights Reserved. Page Week One Review –ABI Black Belt v1.1 Key Terms Value-adding activities transform the product in a way the customer would be willing to pay for. Value stream is a series of activities, both those that create value and those that do not, required to deliver a product or service. Value stream mapping is a tool used to document (map) all activities of a value stream to clearly see waste and variations.

7  2012 American Society for Quality. All Rights Reserved. Page Week One Review –ABI Black Belt v1.1 5 S SORT involves sorting through the contents of the workplace and removing unnecessary items. STRAIGHTEN involves putting the necessary items in their place and providing easy access. SHINE involves cleaning everything, keeping it clean daily, and using cleaning to inspect the workplace and equipment for defects. STANDARDIZE involves creating visual controls and guidelines for keeping the workplace organized, orderly, and clean. SUSTAIN involves training and discipline to ensure that everyone follows the 5S standards.

8  2012 American Society for Quality. All Rights Reserved. Page Week One Review –ABI Black Belt v1.1 Basic Statistics Seven basic probability rules 1.All events have a probability between 0 and 1. 2.The sum of all possible probabilities of defined events is equal to 1.00. 3.The probability of an event not occurring is equal to the probability of the event occurring subtracted from 1.0. 4.If events are mutually exclusive, the sum of the probability of occurrence of these events is equal to 1. 5.The probability of the joint occurrence of independent events is the product of the probability of each event. 6.The probability of occurrence of either or both non-independent events is the sum of the probability of each independent events minus the probability of joint events. 7.The probability of observing two dependent events is the product of the probability of the first event and the conditional probability of the second event, given that the first has occurred.

9  2012 American Society for Quality. All Rights Reserved. Page Week One Review –ABI Black Belt v1.1 Your Turn 1 Assume a sample is selected from a normally distributed population with a mean of 12 oz and a standard deviation of.01 oz. 1.What percent of the sample would be expected to have a value greater than 12.02? 2.What percent of the sample would be expected to have a value less than 11.99? 3.Ten percent of the sample would be expected to have X or less. What is X? Find the answers and draw graphs of the results using Minitab.

13  2012 American Society for Quality. All Rights Reserved. Page Week One Review –ABI Black Belt v1.1 Error Proofing Error proofing is a systematic approach for anticipating and detecting potential defects and preventing them from reaching the customer (internal or external) Proactive identification and prevention Prevent first Do not allow defects from going further Intentionally designed, not by chance At the source—close to the origination Inexpensive first Transparent to the operator Absolutely reliable
