IASSC Certified Lean Six Sigma Green Belt – Discussion on control phase

1. Lean control and Defect prevention

Welcome back to the first session on Control Phase. At Control Phase, you will study about how to sustain the improvement effort made on your process. It includes topics like Lean Control where you will study about the different types of lean tools to stabilize your process performance. At Defect Control you will study about the Boca Egg technique for your defect prevention and at Statistical Process Control you will study about the control chart analysis and identify whether your process is in control or not.

And Control Plan is totally about the documentation required for your six sigma project. So when we talk about the questions asked on lean controls are totally based on the application of tools like Fires methodology, Kombu and Kaiser Giroga technique total productive maintenance, Smid visual, factory standardized work value stream mapping, push and pull system, ETCA. So you need to aware about the topics like how to implement Fios in organization at each step, what you have to do when you are implementing Fios, what are the benefits of Fios.

Also, you are aware about the benefits of Visual Factory and standardized work after its implementation and which things you require during implementation of these lean tools. Also, what Kanban system control in your processes? What are the different types of Kanban Card system? What are the prerequisite required before implementing Kaizen? As Sexima Project is itself an example of Kaizen how these all lean tools are interdependent on each other when you are performing a process improvement project.

So be aware of these lean tools and clarify your all the concepts, then you can easily solve application based question. And when we talk about the defect control here, we will totally focus on Pokia IG technique which is a defect preparation technique. What is its purpose, what are the different types of Pop IQ technique and go through multiple examples of Poop IQI to understand it practically what are the advantages of Pokie IG technique or the lean tools? What does mean by a five to six sigma level process? What one to two sigma level process represent? So be aware of this topics to clarify your concepts and then you can easily solve the questions on this topic. Also.

2. Statistical process control and control plan

Welcome back to the second session on control phase. Here we will talk about statistical process control and control plan. So to prepare for this section, you need to have understanding about the purpose of SPC, whether it perform on input or on output. What are the different types of control charts used for control chart analysis? What are their application? When to use xbarr chart? When to use NP chart p chart like that. How to calculate control chart limits and center line for each type of charts manually. What is the meaning of rational subgrouping? How to form rational subgroups before control chart analysis. How to select data for your statistical process control. How to perform control chart analysis on continuous and attribute type of data. How to interpret the result of it, which are the different rules are used to interpret the control chart analysis? To detect the spatial causes? What is the difference between spatial and common type of causes?

So go through all these concepts and in Control phase, the most important tool is improvement selection matrix. This tool provides the best improvement solution out of the multiple option for your process improvement. And it will select this best solution on the basis of criteria, impact, cost and time. So understand these tools. How to use these tools for your best improvement solution selection. This tool works similar to the XY diagram on the basis of highest ranking. We will select the best improvement solution for our process improvement.

So go through these tools also and the next term is control plan. So here understand the elements of control plan. What is the purpose of training plan? What is the function of response plan? Where monitoring plan and implementation plan is required during your Six Sigma project? Who is responsible for each type of plan? Go through all these concepts in this way, you need to prepare for this section. Thank you.

3. Sum up control phase

Welcome back. Now we already cover our discussion on Control Phase. This is also a simple phase to understand. Like, define phase. So you have chance to score more points on this phase during your exam. So prepare very well for a Control Phase and practice the Control Chart analysis on Minitab and try to interpret the result of it. So that clarify your concepts and parallel. Go through ICGP manual, read the Control first section from that manual and analyze understand how to sustain the improvement effort on your process. And again, same thing here.

Once your preparation is done, then I can come back to the course. Practice the 50 questions on Control Phase, analyze yourself and prepare according to that. So we will end up our discussion on Control Phase. See. Now we cover our discussion on each phase of DMAC methodology individually with a 50 practice question on each phase. So once your preparation is done, then come back to the next session where you will get a two full length mock exam. If your preparation is done at this stage, then start attempting that exam. Thank you.
