When a 1,200-person aerospace manufacturer brought in new operational leadership, the transition stalled for nearly a year. Turnover was so poorly tracked that leadership had no visibility into the problem — they simply replaced departing workers with temps. HM Pinnacle was engaged to diagnose the root causes, build measurement infrastructure, and redesign the people operations system. Within 16 months, the organization moved from stabilization into a growth phase, reducing turnover to 24% and generating an estimated $4.8 million in annual savings from a 5-point reduction alone.
A Year of Failing Leadership Changes Exposed a Broken People System
The client — a 1,200-employee aerospace manufacturing facility — had brought in new operational leadership to drive performance. But after nearly a year, the transition was failing. The core problem was invisible: turnover was not being tracked. When employees left, they were simply replaced with temporary workers. No one measured the cost.
HR had become a compliance function, not a strategic one. Of the 8 to 10 HR staff, many actively resisted change. There was no exit interview process, no KPI tracking, no mechanism to surface patterns in attrition or engagement.
“They weren’t tracking turnover at all — just replacing people with temps and hoping for the best.”Heather MacKay-Mencheski
Building Visibility, Accountability, and Career Architecture from the Ground Up
HM Pinnacle’s engagement began with diagnostics: exit interviews, skip-level conversations, and baseline KPI development. The goal was not just to reduce turnover, but to make it measurable and actionable.
Key interventions:
- Exit interviews and KPI tracking: Created the organization’s first systematic approach to understanding why people left
- Open communication protocols: Established direct channels between leadership and frontline workers
- HR team restructuring: Three of the 8–10 HR staff who resisted the new direction were replaced
- Dual career paths: Created parallel leadership and technical advancement tracks so high performers didn’t have to choose management to advance
Turnover Dropped to 24% and the Organization Shifted from Survival to Growth
“We created dual career paths so your best people didn’t have to become managers to advance. That changed everything.”Heather MacKay-Mencheski
What CEOs Can Learn from This Transformation
Key Takeaways
- You can’t fix what you don’t measure. This organization had no turnover data. The first step was making the problem visible.
- HR must be a strategic function, not a compliance department. Resistant HR staff were blocking organizational change. Leadership had to make hard personnel decisions within HR itself.
- Dual career paths retain technical talent. Not everyone wants to manage. Creating a technical advancement track kept high performers who would otherwise leave.
- Expect 3 quarters for buy-in. Cultural change takes time. Leadership must sustain visibility and commitment through the initial resistance period.
- Quantify the cost of turnover. At $80K salary plus 24% benefits, the financial case for retention investment became undeniable.
- Stabilization precedes growth. Trying to grow before the people system is stable amplifies every existing problem.

How long does a typical people operations transformation take?
Most organizations see initial measurable improvement within 6–9 months, with full stabilization occurring between 12–18 months. The aerospace engagement reached growth phase at 16 months.
What does HM Pinnacle do differently from a traditional HR consultant?
HM Pinnacle focuses on people operations as business infrastructure — not just compliance or policy. The approach integrates measurement systems, leadership development, and organizational design.
Do you work with organizations outside manufacturing?
Yes. While this case study focuses on aerospace manufacturing, HM Pinnacle works across industries including healthcare, food production, technology, and professional services.
What is the typical ROI of a people operations engagement?
ROI varies by organization size and turnover levels, but a 5-point reduction in turnover for a 1,200-person facility at average salary of $80K generates approximately $4.8 million in annual savings.
How do you handle resistant HR teams?
The approach starts with alignment conversations and clear expectations. When staff fundamentally resist the strategic direction, leadership must make personnel changes within HR — as happened in this engagement.
