Payroll Implementation Case Study for a UK Automotive Retailer

Configuring 500 shift patterns in ADP iHCM2 without delaying delivery.

A complex payroll build phase needed fast, accurate shift pattern setup at scale, while keeping the wider implementation on track.

About The client

Mon Motors

This project involved an end-to-end payroll implementation for a UK automotive retailer with more than 500 employees. The client operates across leading vehicle brands and required payroll configuration in ADP iHCM2 as part of a time-sensitive delivery programme.

A key requirement emerged during the build phase: 500 shift patterns had to be configured within a short timeline. Because these patterns sat close to downstream activities, any delay risked affecting data migration and parallel testing.

How It Went

The Challenge

  • The client required 500 shift patterns to be configured in ADP iHCM2 within a short timeline.
  • Shift pattern requirements changed frequently during the build phase.
  • Manual configuration of 500 patterns would have taken significant time and created delivery risk.
  • Delays at this stage could have impacted later phases such as Data Migration and Parallel testing.

How We Did it?

Our Solution

We responded with a practical delivery approach focused on speed, control, and accuracy. The payroll team planned resources early, assigned multiple team members to the workload, and used ADP import tools to accelerate configuration instead of relying on a fully manual process.

Because the client continued to introduce changes, the team also stayed flexible throughout the build phase and worked extended hours where required. This combination of structured resourcing and automation helped complete a 3 month project with the build phase completed ahead of schedule, while keeping all 500 shift patterns aligned to client requirements.

Joint Effort

The Collaboration

This was a highly collaborative engagement between the client team and the PHRism payroll specialists. As requirements evolved, updates were incorporated continuously so that configuration work stayed aligned with operational needs.

Alongside delivery speed, quality assurance remained important. Each configuration set was checked before the project moved into the next stage, helping the wider implementation progress without disruption.

FAQ's

About This Project

This project was complex because 500 shift patterns had to be configured during the Build phase in a short timeframe, while the client continued to introduce changes.
They were a critical part of the ADP iHCM2 payroll setup. If they were delayed or configured inaccurately, downstream stages such as Data Migration and Parallel testing could have been affected.
The team used ADP import tools to automate shift pattern creation and assigned multiple team members to the workload.
The main risk was that manual configuration and frequent requirement changes could have pushed back the wider implementation timeline.
The client introduced frequent changes, but the team stayed flexible, incorporated updates promptly, and still completed the Build phase ahead of schedule.
The strongest outcome is that all 500 shift patterns were configured as required, and the project was delivered before deadline without delaying Data Migration or Parallel testing.
