✍️ Sample CPP Questions & Answers
1. A stakeholder who was initially supportive of a process change becomes resistant after a reorganization. The process team should FIRST:
Organizational changes alter stakeholder interests and power dynamics, requiring a fresh assessment before adjusting the engagement strategy.
2. In a CI culture, how should failures and mistakes primarily be treated?
Treating failures as learning opportunities rather than causes for blame encourages transparency, experimentation, and systemic problem-solving.
3. What distinguishes an API-based integration from RPA when automating inter-system data transfer?
APIs interact with application logic directly, making integrations more robust and less susceptible to UI changes compared to RPA, which mimics screen interactions.
4. A process engineer notices a sawtooth pattern on an X-bar chart. What is the most likely cause?
A sawtooth pattern often indicates that samples from two different streams (machines, shifts, operators) are being combined into subgroups, inflating within-subgroup variation.
5. What is the Average Run Length (ARL) used to evaluate in control charts?
ARL measures how many samples on average are plotted before the chart signals, used to compare chart sensitivity and false alarm rates.
6. A process improvement team completes a successful project but the gains erode within six months. What cultural factor is most likely responsible?
Without standardization and management system reinforcement (audits, visual controls, leader coaching), processes revert to old habits over time.
