PPARS failed because not even NASA could build a computer system that could comfortably handle the nuances of the pay scales, grades, allowances, exceptions etc of the HSE or indeed, most of the Irish CS/PS
The figure given here is €133 million.

Of all the examples of incompetence by the public sector in recent years and wastes of taxpayers money this one has always bugged me the most.
And the solution here "really was very simple" I will explain it in a minute.
Most of the many spent was paid to private sector consultants. Who gladly accepted the money to attempt an impossible task.
I would go further than Delboy and say that the problem isn't that that the structure is complicated, a computer could handle that, the problem is that there is no coherent pay arrangement for many in the public sector.
I know for certain, that for some private sector employees whose wages were dictated by JLC agreements, the employers simply guess their wages because there is no coherent structure. Just a series of rules that have built up over time, which in many areas contradict each other.
I have had it confirmed to me by a senior HSE manager that this was why PPARS failed.
Its really very simple
All you have to do Minister Veradkar is buy a payroll system off the shelf that is capable of handling say 1 million employees on say 200 pay rates. Such systems cost in the hundreds of thousands (not millions) of Euro.
Then inform all staff that they will have to move to the new system. If their pay structure cannot be accommodated by the new system, the pay structure will have to be modified so that it can. Simple.
This really very simple approach was adopted by Revenue when they introduced ROS. Every accounting system in the country had to be adapted to fit ROS.
By contract to PPARS, the introduction of ROS was a great public sector success.
