Case Study · CHANGE MANAGEMENT
How PNAC's HR Advisory in Chicago guided a 300-person industrial manufacturing firm through enterprise-wide operational change, delivering 94% employee adoption and zero key attrition across every department.
Client Brief
This Chicago-based industrial manufacturing firm, a 300-employee operation spanning production, logistics, and corporate functions across two Illinois facilities had committed to the most consequential operational change in its thirty-year history: a full ERP platform migration, a restructured supply chain model, and a complete redesign of its shop-floor reporting hierarchy, all on a compressed twelve-month timeline driven by a private equity ownership transition.
What leadership had not accounted for was the human side of transformation. There was no structured change management framework, no communications strategy for frontline workers who had operated the same systems for a decade, and no capability within the existing HR function to design and manage the behavioural shift at the scale required.
Resistance had already surfaced. Three senior managers had raised formal concerns with the board. Unofficial attrition risk was being discussed in executive team meetings for the first time. The private equity timeline left no margin for delay or rework.
Leadership engaged PNAC as their dedicated HR Advisory and Change Management partner for Chicago, bringing in an external team with the strategic depth, operational discipline, and people expertise to lead the transformation from the inside.
What Was Holding Them Back
No Change Management Architecture
There was no formal Change Management framework in place. Transformation initiatives were communicated through ad-hoc emails and informal team meetings, creating confusion, rumour, and growing anxiety across Chicago facilities that an experienced HR Advisory partner needed to address immediately.
Frontline Resistance at Scale
Production floor employees with ten or more years of tenure were openly resistant to the ERP migration and reporting structure changes. Without a credible, empathetic HR Consulting strategy, the transformation risked stalling at the most operationally critical layer of the business.
Leadership Misalignment on Goals
Three of six senior leaders were actively misaligned on transformation priorities. Without a unified narrative and structured HR Advisory support, the business faced competing messages reaching employees simultaneously, the fastest way to erode trust during any major organisational change.
Inadequate Manager Change Capability
Middle managers had received no training in change leadership, difficult conversations, or performance coaching under ambiguity. PNAC's HR Partner engagement needed to rapidly build this capability without disrupting live operations across Chicago facilities.
Attrition Risk During Transformation
Informal exit conversations were already happening among high-tenure employees. The business could not afford to lose institutional knowledge during the ERP migration, yet it had no structured retention strategy, engagement framework, or HR Consulting support to prevent it.
No Change Impact Measurement Framework
The private equity board required rigorous milestone reporting on transformation progress. Without a data-driven Change Management measurement framework, leadership could not demonstrate adoption velocity, readiness scores, or risk indicators to the board.
PNAC's Approach
PNAC deployed its proprietary Change Readiness and Adoption (CRA) framework across three structured phases: Assess, Activate, and Anchor, with workstreams customized to each employee population across the Chicago manufacturing operation. Continuity of production was maintained throughout the full twelve-month engagement.
Change Impact Assessment & Stakeholder Mapping for Chicago
Before prescribing any intervention, PNAC conducted a structured Change Impact Assessment across every business unit and employee segment in the Chicago facilities. We mapped stakeholder influence, readiness levels, and risk concentrations, producing a phased transformation roadmap with named accountability owners, milestone gates, and board-reportable progress metrics aligned to the private equity timeline.
Leadership Alignment Programme
As the client's dedicated HR Advisory partner, PNAC convened a structured Leadership Alignment Programme for the six-person executive team. Through facilitated strategic sessions, we built consensus on the transformation narrative, decision-making authority during change, and a unified communication framework, converting a divided leadership group into a coherent, credible coalition visible to every employee across Chicago.
Manager Change Capability Acceleration
PNAC designed and delivered a bespoke Change Leadership development programme for all twenty-two middle managers across the Chicago operation. Modules covered leading teams through ambiguity, conducting change conversations with psychological safety, managing performance during disruption, and modelling visible commitment to transformation goals.
Segmented Employee Communication & Engagement Architecture
Our HR Consulting team designed a multi-channel, audience-specific communication strategy covering production floor employees, logistics teams, and corporate functions separately. Cascading briefings, town halls with live Q&A, a physical Transformation Hub in the Chicago facility, and bilingual materials for ESL workforce segments ensured every employee received the same message adapted to their context, from a trusted source.
ERP Adoption & Training Infrastructure
PNAC embedded an adoption readiness framework directly into the ERP go-live timeline. Role-specific training pathways, peer coaching networks, and a supervised parallel-run period with dedicated HR Advisory support ensured no employee was left behind. Adoption was measured weekly against milestones, with real-time intervention for teams falling below the threshold.
Retention Strategy & Change Fatigue Monitoring
PNAC designed a customized retention framework targeting high-tenure, high-risk employees across Chicago. Pulse surveys, stay interviews, manager-level early warning indicators, and a structured recognition programme ran throughout the transformation, ensuring change fatigue was identified and addressed before it became attrition. Zero key employees were lost during the engagement.
PNAC didn't just manage the change; they owned it alongside us. For the first time, our people understood why the transformation was happening, what it meant for them, and how to succeed through it. That's what made the difference.
VP OF OPERATIONS, INDUSTRIAL MANUFACTURING FIRM, CHICAGO
Outcomes Delivered
Within twelve months, the Chicago manufacturing firm completed its transformation on schedule and under budget. The organisation entered its next private equity growth phase, powered by a change-capable, aligned, and fully engaged workforce.
Industry-Leading Adoption Rate Achieved
94% of employees in Chicago facilities achieved full ERP proficiency within the go-live window, more than three times faster than the industry average for comparable manufacturing transformations, validated through skills assessments and productivity benchmarks tracked by PNAC's HR Advisory team.
Zero Key Talent Lost During Transformation
Not a single high-tenure or business-critical employee exited during the twelve-month engagement. PNAC's retention strategy and change fatigue monitoring programme successfully held the workforce together through the most disruptive period in the organisation's history.
Productivity Increased 41% Post-Go-Live
Within ninety days of ERP go-live, production output per shift increased by 41%, driven by streamlined reporting, eliminated manual workflows, and a workforce that had been prepared, not just trained for the new operating model. The transformation paid for itself within the first quarter.
Leadership Aligned and Change-Capable
All six executive leaders completed the PNAC Leadership Alignment Programme and delivered consistent, credible transformation messaging. The board noted measurable improvement in leadership cohesion scores and used the PNAC framework as the blueprint for all future strategic initiatives.
Manager Readiness Score of 88%
Post-programme assessment placed the Chicago management cohort at an 88% readiness score significantly above the 60% benchmark for manufacturing sector change programmes. Nineteen of twenty-two managers rated their ability to lead future transformation cycles as high or very high.
Board-Grade Change Reporting Infrastructure
A live transformation dashboard tracking adoption velocity, change readiness by segment, attrition risk, training completion, and engagement scores gave the private equity board real-time visibility throughout the programme. Every milestone was met on time. No surprises. No escalations.
