Canada to Scrap IBM Payroll Plan Gone Awry Costing $1B
So, what makes a payroll system at this scale so difficult? On the face of it, there are salary employees and there are hourly employees. How many taxing bodies does Canada have? Federal, provincial, and municipal? Is that a few dozen or a few hundred? Is Canadian tax code crazy complicated that doesn't allow for a rules based system?<p>I'm honestly curious as to how a "simple" payroll system can go so far off the rails.
