Problem 2 — Incentive design and unintended consequences (20 pts) A company introduces a KPI: “tickets closed per day” to motivate customer support agents. After rollout, closures increase but customer satisfaction drops. Using course frameworks, do the following: a) Map the causal chain from KPI change to decreased satisfaction (diagram + brief labels). (8 pts) b) Propose a revised KPI system with three metrics that balance speed, quality, and learning; justify each. (8 pts) c) Describe an A/B test to validate the new system over 8 weeks (sample sizes, primary outcome, and stopping criteria). (4 pts)

For engineers and policymakers, the message is clear: The era of the lone PI is fading. The era of the regional engine is here.

Section D — Case analysis and essay (40 points) Choose one of the two case prompts below and write a structured analysis (≈800–1000 words). Use headings for Problem, Stakeholders, Constraints, Options (with 3 alternatives evaluated), Recommendation (single clear choice), Implementation plan (6–9 actionable steps), and Risk mitigation.

: Corporate transparency and adherence to social responsibility policies. Innovation

This often appears alongside 347V lighting specs for "cleanroom" or "biosafety" environments. It ensures the fixture is sealed against dust and moisture (IP66 rated) and can withstand heavy disinfection.

Skipping daily cleaning leads directly to spray arm blockages, poor wash results, odor formation, drain biofilm, and failed health inspections.

In the context of government work and data, is a report published by the National Center for Science and Engineering Statistics (NCSES) .

347V is a high-voltage industrial phase often used for large-scale lighting. Many LED drivers, such as those from Kenall , must be specifically rated for 347V to function without failing.

Which (LEED, Green Globes, etc.) are you targeting? Do you need help finding certified manufacturers ?

The National Sanitation Foundation (NSF) is an international public health and safety organization that develops public health standards and provides certifications for many industries, including foodservice. For a commercial kitchen, NSF certification is not a luxury; it is a baseline requirement for legal operation and public safety.

Certification is awarded in tiers based on the total points accumulated: Conformant (Entry level)

In Alabama, the NSF Engine for Regenerative Medicine (led by the University of Alabama at Birmingham) is a case study in this tension. UAB has world-class trauma surgeons, but they historically lacked a supply chain for synthetic skin and muscle scaffolds.

Real-world example: In 2022, a refinery in Texas suffered a $50 million fire because a welder’s spark ignited a nearby hydrocarbon vent. The root cause? No fire watch and an incomplete permit.

Duration: 3 hours Total points: 200 Instructions: Answer all required sections. Write clearly. Where asked, show reasoning, cite any assumptions you make, and use examples or diagrams when helpful. Use concise, well-organized answers; quality of explanation and application of concepts is graded as heavily as correctness. You may use a calculator and one double-sided formula sheet.

Use of environmentally responsible materials and end-of-life recyclability.
