This case effectively combines quantitative analysis with strategic problem-solving by first quantifying the cost impact of ranger attrition (showing Law Enforcement rangers have the highest per-person cost despite lowest departure numbers), then shifting to qualitative solutions grounded in identified pain points. The structure progresses logically from problem definition to cost analysis to root cause brainstorming, mimicking real consulting engagement methodology.

Our client is the United States Department of the Interior, which is responsible for the National Park Service (“NPS”). The NPS employs park rangers across all federally owned parks, ranging from Yellowstone and the Grand Canyon to the Statue of Liberty and Lincoln Memorial. National Parks employ four different classifications of rangers: Law Enforcement, Education, Maintenance, and Administrative. The focus of this case is on the Law Enforcement rangers, who have similar responsibilities to police and firefighters. They are trained in areas that include wilderness medicine and search and rescue. The client is concerned that job retention is low among the Law Enforcement rangers. They would like you to explore how big the problem is and think about ways to improve it.

A public sector workforce retention case focused on the National Park Service’s Law Enforcement rangers. The case requires candidates to calculate attrition costs by ranger type, identify that Law Enforcement rangers impose disproportionately high costs when they leave ($35,300 per ranger vs. $3,500-$6,200 for other types), and brainstorm solutions addressing three identified pain points: family-friendliness, senior leadership effectiveness, and performance-based rewards.

Key Insights:

  1. Cost per lost employee varies dramatically by role ($35,300 for Law Enforcement vs. $3,500 for Administrative), making prioritization essential despite similar attrition rates
  2. Problem framing matters: Law Enforcement has lowest absolute turnover (98 of 2,100) but highest total cost impact ($3.46M), demonstrating why cost analysis should drive prioritization
  3. Root cause analysis should precede solution generation: survey data showing specific pain points (family-friendliness, leadership, rewards) enables targeted interventions rather than generic HR solutions
  4. Solutions should be structured by problem category and include consideration of implementation costs and feasibility, not just theoretical benefits
