The concept of corporate Shared Services (SS) has been around a long time, with the private sector credited with starting this concept in the late 1980′s, and the public sector about a decade later. Personally, and not trying to date myself, I came across this business model at a former employer around 2005. Simply put, SS is an operating model that enables function-specific resources (i.e., HR, IT, Finance, etc.) to be leveraged across an entire organization, resulting in lower costs with agreed-upon customer-service levels. It’s utilization by both the private and public sector grew consistently over time, and then came the 2008/2009 recession. At that time, companies desired even greater efficiency, wider geographic reach, and broader scope coverage from its SS, to handle greater regulatory scrutiny for the same or even lower costs! These demands caused a bit of an inflection point, and the next stage in SS maturity started taking hold… Global Business Services (GBS). So, what is GBS?
