Lean Six Sigma Leadership LEAN versus Six Sigma Waste Flow Continuous Improvement
LEAN versus Six Sigma Six Sigma is about meeting the customer demand for accuracy (Quality) LEAN is about meeting the customer demand for timeliness (Speed) LEAN and Six Sigma complement each other. Each drives continuous improvement through the DMAIC methodology
Six Sigma Quality LEAN Six Sigma Method: Improvement (DMAI2C) – Reduce variation and defects in an existing process Define the project, process, and customer requirements. Measurethe process to set baseline and quantify factors. Analyzethe data to determine root cause. Innovate Improvements that address root cause. Controlimproved process and determine effect.

Lean is about decreasing waste.

50 newborns harmed at delivery, every day 5,000 incorrect surgical operations a week 200,000 wrong drug prescriptions a year No electricity for almost 7 hours a month 20,000 lost articles of mail per hour Unsafe drinking water almost 15 min. a day 528,000 checks deducted from the wrong bank accounts every day At Quest Diagnostics, we perform nearly 350 million tests a year. If we did 99% of them right: 3.5 Million Tests would have an error! We want Six Sigma Quality: 99.9997% of tests done correctly! Less than 1200 would have an error Six Sigma Quality Six Sigma: The Highest Quality 99% Good Means: Quest Diagnostics Quality:

What the Customer Wants Average = 13 Minutes
Which is Better? The average wait time is decreased by 2 min. The # of patients waiting >15 min. has increased from zero to ~20 But…. Average = 13 Minutes Average = 11 Minutes Most customers don’t experience the average!

Six Sigma Quality Reduce or eliminate waste DOTWIMP • Defects • Overproduction • Transport • Waiting • Inventory • Motion • Extra Processing DOWNTIME • Defects • Overproduction • Waiting • Non-Utilized Employees • Transport • Inventory • Motion • Extra Processing
Six Sigma Quality Perspective • From the Function/Provider: Everyone is very busy • From the patient: Hurry up and wait • From the specimen: Sit, Sit, Sit, Test, Sit
Six Sigma Quality What is Value?
Value Added: Definition • Must Physically Change the product / information • Must be Done Right the First Time (no rework) • Customer is Willing to Pay For It
Lean Toolkit – 5S Six Sigma Quality 5S Parody • What is it ?? • A systematic way to improve your workplace and processes • Focuses on creating and maintaining a clean, well organized workplace • Easily distinguish between normal and abnormal conditions • Highly dependent on employee involvement • Promotes defect reduction, cost reduction and a safe work environment • Goal: • A self-explaining, self-ordering, self-regulating, and self-improving workplace where what is supposed to happen does happen on time, every time, day or night.

Implementation and Benefits of 5S 5S Exercise Set in Order Sort Shine Standardize Sustain Sort: “When in doubt throw it out” Sort necessary from unnecessary items • Remove all unneeded items such as racks, tools, equipment, and excess inventory • Red tag method • Attach red tags to unneeded items and remove them to a red tag area • Evaluate and properly dispose of items in the red tag area Sort - Benefits • Work area less crowded • Less time needed to find things • Fewer part selection errors • Improved process flow • Reduced maintenance costs • Improved communication among employees
Sort • Get rid of what you do not need. Keep only what is needed. • (Remove higher numbers) 5S Exercise 5S - Circle the numbers in order from 1-50 You have 60 Seconds 60 55 50 45 40 35 30 25 20 15 10 5 Time’s Up
Implementation and Benefits of 5S 5S Exercise Sort Shine Standardize Sustain Set in Order Set in Order : “A place for everything and everything in its place” Arrange items so that they can be found quickly by anyone • Everything that is movable should have a designated place when not in use • Arrange things so they are easy to find, easy to use and easy to put away • Most frequently used items should be close-at-hand • Items should always be in the same place Set in Order - Benefits • The proper amount of space is designated to store items • Reduces time needed to find things, less searching • Everything is in its place and not on the floor – improved safety • Elimination of excess motion • Increased space / capacity
Implementation and Benefits of 5S 5S Exercise Set in Order Sort Shine Standardize Sustain Shine: “A clean systematic organization results in increased safety and efficiency” Create a spotless workplace • Keep what is left CLEAN and in good working condition • Perform a major cleanup • Assign daily housekeeping tasks at least 5 min./day Shine - Benefits • Less equipment breakdown. • Defects are easy to see • Improved efficiency • Safer work environment • Improved morale
2. Set in Order Put needed items in the proper place (No sequential numbers in the same quadrant) 3. Shine Keep workplace neat and clean (Clean up fonts) 5S Exercise 5S - Circle the numbers in order from 1-50 You have 60 Seconds 60 55 50 45 40 35 30 25 20 15 10 5 Time’s Up
Implementation and Benefits of 5S 5S Exercise Set in Order Sort Shine Standardize Sustain • Standardize:“Do the right things the right way, every time” Maintain the previous changes and continuously improve • Standardize your processes • Incorporate sorting, storage, and shining activities into daily routines • Use aids to control what happens and when it happens Standardize - Benefits • Increased equipment life • Clean environment • Increased visibility of normal and abnormal conditions • Consistent delivery • Improved quality • Training of new employees is easier

Takt time Takt time = (time available)/(customer demand) Example: 480 specimens arrive to the lab at 9 pm, are processed and delivered to toxicology at 10 pm. All results are due for release by 8 am. If an AU2700 can do 1 rack of 10. How long should 1 rack take to meet the 8 am TAT? Available time = 9 hours – 30 minutes for lunch – 2 x 15 minutes for breaks = (9*60) – 30 – 30 = 480 minutes Customer demand = 480 specimens (assume no splits) Takt time = 480/480 = 1 minute = 60 seconds 1 rack = 10 specimens 1 rack = 10 * 1 = 10 minutes What is the practicality of this?
Work Elements for the Histology Project Operator Balance Chart Takt time = 11.36 sec. What do you notice about this picture?
Operator Balance Chart with Improvement Takt time = 11.36 sec. Planned Cycle Time = 9.66 sec. Note: We need to plan 85% - 95% of takt time to allow for variability in the process 11.36 X 85% = 9.66

Kaizen: the philosophy that continuous improvement takes place through small, incremental process improvements, repeated over and over again What is Kaizen? Workshop: • A means of implementing process improvements • Short, 3-5 day events with intensive focus on one area and problem (for example cycle time or rework) • A cross-functional, participative implementation approach • Focus on substantial improvement (30-40%) Workshop Objectives: • Achieve results • Bring new problem solving skills to the workforce
