Correct answer: Six Sigma methodology; its primary focus is the reduction of process variation to ensure consistent delivery times.

While Lean focuses on eliminating waste, Six Sigma is specifically designed to reduce process variation and improve consistency. Because the firm's main issue is the high variance in delivery times (2 to 8 days), Six Sigma (using the DMAIC framework) is the optimal methodology to stabilize the process and achieve predictable outcomes.

Correct answer: Storming

The 'Storming' phase is characterized by conflict, resistance to assigned roles, and polarization of opinions. It occurs after the initial 'Forming' stage as team members begin to assert their individual perspectives. stateDiagram-v2 [*] --> Forming Forming --> Storming: Conflict emerges Storming --> Norming: Rules established Norming --> Performing: High productivity Performing --> Adjourning: Project ends

Correct answer: 12,500

DPMO is calculated as: (Total Defects / (Total Units × Opportunities per Unit)) × 1,000,000. Here, Total Defects = 25. Total Units = 500. Opportunities per Unit = 4. Calculation: (25 / (500 × 4)) × 1,000,000 = (25 / 2000) × 1,000,000 = 0.0125 × 1,000,000 = 12,500.

Correct answers: Nominal Group Technique (NGT); Multivoting

Nominal Group Technique (NGT) and Multivoting are both structured decision-making tools designed to democratize the selection process. NGT involves silent generation of ideas followed by anonymous ranking, which directly prevents dominant personalities from taking over. Multivoting allows a team to narrow down a large list of options through a structured series of votes.

Multivoting allows a team to narrow down a large list of options through a structured series of votes. Along with NGT, it prevents dominant personalities from skewing the results.
