Enterprise-wide Planning · Improvement Methodologies
A manufacturing plant has 5 sequential operations. Operation C has a maximum capacity of 50 units/hr, while all other operations can process 80 units/hr. Market demand is 70 units/hr. The plant manager wants to apply Lean Kaizen events to operations A and B to speed them up further. As the MBB, what is the optimal intervention based on the Theory of Constraints (TOC)?

Correct answer: B
According to the Theory of Constraints (TOC), the system's throughput is dictated solely by its bottleneck (Operation C). Improving non-bottleneck operations (A and B) will only generate excess inventory and waste, not increase throughput. The correct TOC application is to subordinate the rest of the system to the bottleneck and focus all improvement efforts on elevating the capacity of Operation C.

Enterprise-wide Planning · Pipeline Management
An MBB is managing the enterprise Six Sigma project pipeline. The pipeline currently has 45 active projects, but resource capacity only allows for 20. Which TWO actions represent the BEST practices for pipeline life-cycle management in this scenario? (Select TWO)
Show answer & explanation
Correct answers: B, D
Pipeline lifecycle management requires active monitoring and intervention. When resources are constrained, best practices dictate consolidating overlapping projects to maximize resource efficiency. Additionally, projects that no longer align with strategic goals should be retired to free up capacity for high-priority initiatives.

Enterprise-wide Planning · Infrastructure Elements of Improvement Systems
What is the primary role of a Quality Council (or Process Leadership Team) in the infrastructure of a Six Sigma deployment?
Show answer & explanation
Correct answer: A
The Quality Council or Process Leadership Team serves as the governance body for a deployment. Their primary responsibilities include aligning projects with corporate strategy, providing necessary resources, removing organizational roadblocks, and ensuring the deployment remains on track. They do not execute the projects themselves.

Enterprise-wide Planning · Improvement Methodologies
A financial services company is launching a completely new digital banking platform. The current legacy system cannot be upgraded to meet the new customer requirements for real-time cryptocurrency trading. Which improvement methodology should the MBB recommend?
Show answer & explanation
Correct answer: A
DMADV (Define, Measure, Analyze, Design, Verify) is a Design for Six Sigma (DFSS) methodology used when a product or process does not currently exist, or when an existing process cannot be incrementally improved to meet customer requirements. Since the legacy system cannot be upgraded and a completely new platform is required, DMADV is the correct choice.
