Case study
OOUTH Salary Manager – automating payroll for a teaching hospital
Prism Technologies designed and delivered a comprehensive payroll and cooperative deduction platform for Olabisi Onabanjo University Teaching Hospital (OOUTH), powering salaries for thousands of staff with audit-ready controls.
Client
Olabisi Onabanjo University Teaching Hospital (OOUTH), one of Nigeria’s leading teaching hospitals.
Engagement
Discovery, UX/UI, platform engineering, integrations, data migration, training, and ongoing enablement.
Timeline
16 weeks to launch · retained for optimisation and support.
The challenge
OOUTH relied on fragmented spreadsheets, manual approvals, and in-person sign-offs for monthly salary processing. Different departments managed separate records, cooperative deductions, and staff loans, resulting in delays, discrepancies, and compliance risks.
- Salary approvals for thousands of staff required manual collation.
- Cooperative and welfare deductions were tracked outside payroll systems.
- Management lacked real-time visibility into commitments, loans, and pending approvals.
Our approach
We facilitated workshops with HR, cooperative, finance, IT, and union stakeholders to align requirements and success metrics. We then designed an integrated platform that centralises payroll, deductions, and cooperative workflows with audit-ready controls.
- Documented existing processes, pain points, and compliance requirements.
- Prototyped dashboards and approval flows for all stakeholder groups.
- Planned staged data migration covering staff records, loans, and deductions.
