Genesee Health System Ensures Seamless ADP Migration with TestAssure

Genesee Health System provides comprehensive behavioral health services to residents of Genesee County, Michigan, serving a population of over 400,000. As one of Michigan's largest community mental health providers, they operate multiple facilities and programs throughout the county. After 12+ years on their legacy ADP eTime system, they embarked on a critical migration to ADP's modern cloud-based workforce management solution. With 570 employees and biweekly payroll responsibilities, they needed a testing strategy that would ensure zero disruptions while minimizing the burden on internal resources. 

“From our initial call to project completion, TestAssure was there to educate, execute and ensure Genesee's success... With confidence I can say GHS went live faster with 100% payroll accuracy and zero payroll disruptions. I'm not sure I could say that if we didn't use TestAssure.”

- Glen Chipman, CFO, Genesee Health System 

Challenges

Genesee Health System faced several critical challenges requiring professional testing support: 

Diverse Pay Rule Structure 
The system included a wide range of pay rules covering non-exempt hourly employees, salaried employees, part-time & full-time staff, and multiple bargaining and union groups with distinct requirements. 

Time Pressure 
Aggressive implementation timeline with weekly meetings and a firm go-live target. 

Accrual Policies 
Each category required unique validation to ensure correct accrual balances, carryover rules, and eligibility criteria. 

Zero-Error Requirement 
As a healthcare provider serving vulnerable populations, any payroll disruption could cause licensed clinicians, case managers, and support staff to miss critical payments, potentially impacting retention and service delivery. 

The TestAssure Solution

ADP recommended TestAssure based on the complexity and critical nature of Genesee Health System's implementation. The solution delivered immediate value: 

Professional Partnership and Expertise 
The partnership between TestAssure, ADP, and Genesee Health System created a seamless implementation experience. Weekly meetings became productive sessions where TestAssure presented findings, the team made informed decisions, and the ADP implementation team executed adjustments in real-time.  

"It's great to come to the Thursday meetings and have TestAssure say, 'Here's what we found,' and then we can work with ADP implementation to adjust what we're seeing," noted CFO Glen Chipman. This collaborative approach delivered what Chipman valued most: "More confidence in implementation results." 

Comprehensive Testing Coverage 

• Functional Testing validated all configurations and business rules. 
• Parallel Testing offered a side-by-side comparison ensuring payroll accuracy. 
• User Acceptance Testing provided real-world scenario validation. 

Easy-to-Read Test Cases 
As a TestAssure team member explains: “When people review our test cases, it just clicks. They’re not looking at some generic, abstract example they can’t relate to. Instead, they see something like: ‘Okay, this is Jerry, he’s part-time, union, working overnight on a holiday.’ Suddenly it’s real, it’s familiar, and they can instantly connect it back to their own workforce. That level of context makes it so much easier for them to validate whether the configuration is right, because they can see exactly how it plays out in a real-world scenario.” 

"It's great to come to the Thursday meetings and have TestAssure say, 'Here's what we found,' and then we can work with ADP implementation to adjust what we're seeing."

• 140+ hours of expert testing 
• 100% testing coverage with comprehensive validation across functional, parallel, and user acceptance testing.

“We didn't have any issues with any payroll during this testing phase" 

-Glen Chipman, CFO, Genesee Health System

The impact of the TestAssure solution was measurable:

• Ticket Reduction: "Our ticket reduction of the changes that we have to make has drastically reduced"
• Faster Issue Resolution: Issues now immediately identified as configuration vs. employee assignment problems.
• Team Confidence: When issues arise, “we push back... we're confident it's correct" 

Summary
