HR challenges
- Conflicting views and cultures between former rivals
- Extremely thight timelines, spread over three waves, had put the integration teams under heavy pressure
- Internal Stakeholders (HR, IT, finance/procurement) not aligned, lack of decision matrix
- Compliance & security checkpoints facing fragmentation : GDPR/access/audit-trail risk
- Severe employee impact from payroll/HRIS/T&A errors, risking HR's reputation
Intervention
- Governance set up : cross functional steerco's + task forces, cadence, escalatiepath and decision log
- Scope baseline : in/out, assumptions backed up by data, succes criteria and change control proces implemented
- Vendor alignment: one integration plan [SD worx and Dayforce] + [Protime] + [Successfactors] + Implementation partner [Flexso] + internal teams, with clearly defined dependencies
- Risk & compliance rhythm: risk register, checkpoints (GDPR, access/security), audit trail agreements
- Execution cockpit: weekly status update (narrative + KPI/milestones), issue/blocker log and actions with owners
Result
We established clear, end-to-end ownership across the entire transformation lifecycle, by proactively challenging cross-functional dependencies at an early stage and ensuring that potential risks were mitigated long before they escalate into executive-level problems
Deliverables
- Governance rhythm + RACI
- Integrated master plan + dependency map
- Risk register + mitigation plan
- Decision log + change request log
- One-page status reporting template
