A multinational financial services firm has launched an enterprise-wide Lean Six Sigma initiative. As the lead Master Black Belt, you are tasked with designing the project portfolio management process. The executive committee is concerned about aligning projects with strategic objectives, such as 'Digital Transformation' and 'Customer Retention'. Which of the following is the most effective tool for prioritizing and selecting projects in this context?
A Black Belt is conducting a DOE to optimize the yield of a biotech fermentation process. Their initial 2-level factorial experiment reveals significant curvature in the model (p-value for curvature = 0.008). As their mentoring Master Black Belt, what is the most appropriate next step to guide them toward finding the process optimum?
You are mentoring a team on a Design for Six Sigma (DFSS) project for a new medical diagnostic device. The team has completed the 'Measure' phase (of DMADV) and has gathered extensive Voice of the Customer (VOC) data. The primary challenge is to translate qualitative customer needs, such as 'easy to use' and 'provides quick results', into specific, measurable engineering specifications. Which DFSS tool is specifically designed for this purpose?
True or False: In Hoshin Kanri (Policy Deployment), the process of 'Catchball' refers to the top-down communication of strategic objectives from senior leadership to lower levels of the organization without modification.
A Master Black Belt is tasked with creating a sustainable coaching culture within a large manufacturing organization. After initial training, many Green Belts and Black Belts struggle to apply statistical tools correctly and fail to complete projects. Which TWO of the following actions are most crucial for the MBB to implement? (Select TWO)
An e-commerce company wants to predict the likelihood of a customer churning (not making a repeat purchase within 90 days). They have historical data including customer demographics, purchase frequency, average order value, and website browsing behavior. A Black Belt team is tasked with building a predictive model. Which statistical technique is most appropriate for this objective?
A hospital system is undergoing a major cultural transformation to adopt Lean principles, moving from a department-siloed structure to a patient-centric, value-stream-based model. The initiative is facing significant resistance from senior physicians and department managers who feel a loss of autonomy. As the MBB leading the change, which change management model would be most effective for diagnosing and addressing the root causes of this resistance? ```mermaid flowchart TD A[Awareness of the need for change] --> B(Desire to participate and support the change) B --> C(Knowledge on how to change) C --> D(Ability to implement required skills and behaviors) D --> E(Reinforcement to sustain the change) ```
As part of the curriculum development for a new Black Belt training program, a Master Black Belt must decide on the best approach for teaching Design of Experiments (DOE). The goal is to ensure Belts can apply DOE effectively on real projects, not just pass a test. Which instructional design element is most critical to include?
A Master Black Belt is reviewing a project portfolio and needs to select the most impactful initiatives. Four potential projects are presented. Using a project prioritization matrix, which project should be selected? Project A: High Impact, High Effort Project B: Low Impact, Low Effort Project C: High Impact, Low Effort Project D: Low Impact, High Effort ```mermaid quadrantChart title Project Prioritization Matrix x-axis Low Effort --> High Effort y-axis Low Impact --> High Impact quadrant-1 "Strategic Projects" quadrant-2 "Quick Wins" quadrant-3 "Fill-ins / Deprioritize" quadrant-4 "Re-evaluate / Avoid" Project A: [0.8, 0.8] Project B: [0.2, 0.2] Project C: [0.2, 0.8] Project D: [0.8, 0.2] ```
