It requires necessarily a substantial investment. It is a specific device that organizations can purchase.

It is a method that prevents defects.

Which of the following is most correct regarding the Improve tollgate? As the project reaches the Analyze stage, it is certainly worth continuing it. At this stage, changing a project is no longer a tollgate outcome. Different from previous tollgates, the stakeholders are now committed. Because of the advanced stage and resources used, the project cannot discontinue. Like previous tollgates, the project can still be modified.

Like previous tollgates, the project can still be modified.

As a supply chain manager, which of the following is a correct step you need to take to use the impact-effort matrix properly? List all the potential solution and their correlations to CTQ List the root causes and their priority List all the change concepts you plan to use List all the correlations between VOC and CTQ

List the root causes and their priority

In selecting tools and procedures for the Improve phase, you need to focus on: Logic and knowledge about the project Maintaining close adherence to the founding lean thought leader In-depth expertise in sophisticated statistical methods Following the rigid procedures developed for this phase Making sure to deploy all the tools available

Logic and knowledge about the project

Which of the following is most correct regarding errors? 100% inspections are the best way to avoid errors. There is no need to detect failures to follow standardized work. Managing standardized work is important. A crucial way to ascertain quality is to inspect everything at the end of the process. Using multiple people to perform inspection is a sure way to avoid errors.

Managing standardized work is important.

For DMAIC purposes, a change concept is an alternative method for: Performing data collection for the improvement phase Performing a step in a process where a key factor impacts the CTQ Performing a step in a process where a key CTQ impacts the Xs Performing process mapping to gain additional insight Performing the lean work to achieve six sigma outcomes
