  1. Question 1

    Intermediate

    Six Sigma Fundamentals · Six Sigma Foundations and Principles

    A regional logistics firm is experiencing customer complaints regarding highly inconsistent delivery times. Some packages arrive in 2 days, while others take up to 8 days for the exact same route. Management wants to initiate a project to address this. Which methodology is MOST appropriate for this specific goal, and what is its primary focus?

    Answer and explanation

    Correct answer: B

    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.

    Six Sigma Fundamentals · Team Basics

    During a newly formed DMAIC project meeting at a financial institution, team members begin arguing over who should lead specific tasks. Several members are challenging the project scope, and interpersonal conflicts are causing delays. According to Tuckman's model, which stage of team development is this team currently experiencing?

    Answer and explanation

    Correct answer: D

    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.

  3. Question 3

    Advanced

    Six Sigma Fundamentals · Quality Tools and Six Sigma Metrics

    A manufacturing plant produces circuit boards. In a recent batch of 500 boards, quality inspectors found a total of 25 defects. Each circuit board has 4 specific opportunities for a defect to occur (solder joint, component placement, trace integrity, and alignment). The calculated Defects Per Million Opportunities (DPMO) for this batch is _____

    Answer and explanation

    Correct answer: D

    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.

  4. Question 4

    IntermediateMultiple answers

    Six Sigma Fundamentals · Team Basics

    A cross-functional team needs to prioritize a list of 15 potential process improvement ideas. The team leader wants to ensure that all members have an equal voice and that a few dominant personalities do not skew the final decision. Which TWO of the following decision-making tools would be MOST effective in this scenario? (Select TWO)

    Answer and explanation

    Correct answers: A, C

    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.

    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.
