PPARS: Ireland's health payroll system ran from a €9.14m budget to a €195m bill

PPARS — Personnel, Payroll and Related Systems — was meant to modernise how Ireland's health service manages and pays its 100,000-plus staff. Procurement began in January 1997; in 1998 the agencies chose a system built on SAP R/3, and in July 1998 awarded Bull Information Systems a fixed-price implementation contract for six agencies, budgeted at €9.14m and due in about two years. The budget excluded hosting, network upgrades and post-implementation support.

More than three years later, at end-2001, only the personnel-administration modules were live, in six agencies plus the Western Health Board, at a cost of about €17m. Each agency had its own configured version of the system, so adopting a single national system later forced a substantial redesign and rebuild. In May 2002 the Department of Health insisted national coverage was essential, extending scope to more boards, teaching hospitals and voluntary agencies. In October 2002 Deloitte was engaged as project support adviser on time-and-materials terms after a €400,000 scoping exercise.

On 6 October 2005 the Health Service Executive suspended further rollout pending review. The Comptroller and Auditor General's Special Report 51 counted roughly €131m incurred by 31 August 2005 — €57m of it consultants and contractors, including €38.5m to Deloitte — and put the cost of finishing at €195m by the end of 2006, against the original €9.14m budget. Rostering, recruitment and superannuation functions were still undelivered, and the C&AG found both project appraisals fell short of a full business case, with estimates framed around funding requests rather than cost analysis.

The failure was public by then: RTÉ reported in October 2005 that the system had paid one employee €1m in error, that €70m had gone to external consultants, and that final costs could exceed €200m — more than the bill for building Tallaght Hospital. In 2010, five years after suspension, PPARS was still costing the state over €6m a year, with cumulative spend past €180m, and a C&AG finding that there was no proof the system cost less than manual payroll.

Budget €9.14m; €131m spent by Aug 2005; completion re-estimated at €195m — about 21x budget. Deloitte alone billed €38.5m; one worker was paid €1m by mistake.

The fixed-price contract was under-scoped from the start: the €9.14m budget excluded hosting, network infrastructure and post-implementation support.

Each agency got its own configured version of the SAP system, which forced a substantial redesign and rebuild once a single national system strategy was adopted.

Neither appraisal met the standard of a full business case — cost estimates were framed to funding requests, not supported by detailed cost analysis.

The department's urgent need for accurate staff numbers and pay costings pushed the fastest possible rollout, with adverse consequences, in the C&AG's words.

Scope was expanded by mandate in May 2002 to national coverage before the implementation method had proven itself anywhere.

Letting each site configure its own ERP instance multiplies cost by the number of sites; when estimates are framed to fit funding requests, every review approves the next tranche.

The rollout suspension held through successive reviews; functions planned in 1997, including rostering, recruitment and superannuation, remained undelivered years later. Spending trickled on: the Irish Medical News analysis put 2010 running costs at €6.451m, including €3.23m for technical support and €1.149m in software licences. The episode became shorthand for Irish public-sector IT failure — RTÉ's archive labels it 'HSE Computer Chaos' — and a standing warning when later health pay systems were proposed.
