PLAN; what is the proposed change? How are you measure the result of the change? What is the baseline level of performance? What results you predict from your change? What is your theory of improvement? Who will be impacted? How do you plant more than one test? Have you identified potential risks? DO; What did you observe are conducting the test change? Who is affected by the test change? What are the effects? Have you documented your actions? Did you notice any factors are conditions that might affect final results? STUDY; did you follow the plan? If not, why? What were the actual results? How many actual results compare with your predictive results? Can you explain the deviations? Can you quantify the impact some quality, safety, service, cost, net income,? What went well and what didn't go well? ACT; what actions will you take based on what you learned? How are you communicate your findings? Will there be another test of change? If yes, when? What controls will you put in place if the changes were successful?

Resistance is emotional it is indirect expression of discomfort due to fear of loss of control or fear of vulnerability. Extended confusion, can you explain that to me again? Delay, I'm really busy right now maybe later. Defiance. I don't like it and I won't do it. Denial, I don't think there really is a problem. Malice compliance, I'll follow your new procedure to the letter. Whispered, these changes will lead to layoffs. Too easy acceptance, great idea thank you for coming. Deflection, I agree there is a problem but not in my area. Silence.

What does it mean to be in statistical control? What is a control chart?

Statistical control means data is stable consistent predictable and within limits. In order to have confidence that you have statistical control you need to have at least 20 plotted data points over time. If data points are within statistical control, you can somewhat predict what will happen. Control chart is a run shirt with the addition of three lines the centerline, and upper control limit, and the lower control limit. I control chart allows you to monitor performance overtime and determine whether special causes the variation exist.

DMAIC

Define-trying to accomplish what Measure-where should we focus Analyze-what are root causes Improve-what solutions to use Control-what controls do we need to sustain performance A six-sigma process: define, measure, analyze, improve, and control. Used for projects in and improving in existing business process.

What is the essential question for each of the DMAIC steps

Define-what are we trying to accomplish? Measure-where should we focus, where are our strategies? Analyze-what are the root causes? Improve-what solutions should we implement to address the root causes? Control-what standards and controls should we implement to sustain the new performance level?

Describe the components and structure of an Improvement tree

Vision of a positive, compelling future state: clearly stated and understandable to everyone, consistent, ennobling, challenging, accessible. First steps in the direction of the vision: Practical plan with attainable steps. How we might behave with one another. Communicated. Resistance to change: always present when change occurs.

Six Sigma

Organized parallel-meso structure to reduce variation in organizational processes by using improvement specialists, a structured method and performance metrics with the aim of achieving strategic objectives. Disciplined, data-driven approach and methodology for eliminating defects. Developed by Jack Welch, By Motorola six to improve the quality of process outputs by identifying and removing causes of defects/errors and minimizing variability in manufacturing in business processes. Each six Sigma project carried out within an organization follows a defined sequence of steps and has qualified financial targets. Cost reduction and/or profit increase. Six sigma doctor in asserts that continuous efforts to achieve a stable and predictable process results are vital importance to business success. Manufacturing and business processes have characteristics that can be measured analyzed improved and control. Achieving sustained quality improvement requires commitment from the entire organization. Features that fat six Sigma a part from previous quality improvement initiatives include a clear focus on achieving measurable and quantifiable financial returns from any six Sigma project. And increased emphasis on strong and passionate management leadership and support. A special infrastructure of champions black belts master black belt green belts to lead and implement a six Sigma approach.
