Case Studies: Evidence-Based HR in Action

Theory matters—but practice convinces. These case studies show how organizations applied evidence-based HR to solve real problems and drive meaningful change.

Reading about theory is helpful. Seeing it in action is powerful. This page offers real-world examples of evidence-based HR—how different organizations gathered data, interpreted it, and used it to make better people decisions.

Each case includes:

  • The business or HR challenge
  • What evidence was gathered
  • What action was taken
  • What outcomes followed

Case 1: Reducing New Hire Turnover in a SaaS Company

Problem: 90-day attrition among new sales hires exceeded 30%.

Evidence gathered:

  • Onboarding satisfaction surveys
  • Exit interviews
  • Time-to-productivity benchmarks

Intervention:

  • Introduced structured onboarding
  • Added weekly feedback loops
  • Paired hires with peer mentors

Outcome:

  • 90-day attrition fell by 45% in two quarters
  • Onboarding satisfaction increased by 28 points

Case 2: Improving Internal Mobility at a Global Logistics Firm

Problem: High-potential talent leaving due to lack of career development.

Evidence gathered:

  • Engagement survey data
  • Exit interview themes
  • Mobility ratios across departments

Intervention:

  • Created visibility dashboards for internal roles
  • Added mobility conversations to performance reviews
  • Launched a pilot for lateral career moves

Outcome:

  • Internal mobility rate increased from 9% to 17%
  • Voluntary exits among high performers dropped by 19%

Case 3: Enhancing Leadership Effectiveness in Healthcare

  • Manager turnover dropped significantly

Case 4: DEI Strategy Reboot in a Tech Scale-Up

Problem: DEI efforts lacked direction and credibility.

Evidence gathered:

  • Representation data by role level
  • Employee sentiment analysis from open-text feedback
  • External DEI benchmarks

Intervention:

  • Published DEI dashboard company-wide
  • Trained managers on inclusive hiring and language
  • Introduced accountability measures for team leaders

Outcome:

  • Diverse hires in tech roles increased by 22%
  • Inclusion sentiment improved by 14 points
🎉
The company also saw a 30% increase in employee participation in ERGs, credited in part to the transparency of the new DEI metrics.

What These Cases Have in Common

  1. A clear, relevant HR or business problem
  2. Multiple sources of evidence—quantitative and qualitative
  3. A structured approach to interpreting the data
  4. Action grounded in evidence, not guesswork
  5. Follow-through and measurement of outcomes

Conclusion: From Data to Credibility

Each of these cases started with a question. Evidence provided clarity. And action created value. That’s the power of evidence-based HR—not just proving impact, but creating it.
