Rumor has it that Halliburton spent almost $100mil ( or was it $900mil I forget) on trying to do an ERP upgrade so I&#x27;m not surprised at all.<p>It&#x27;s not just about the money though, it&#x27;s also about having the mandate to get shit done (and probably hurting a bunch of feelings&#x2F;fiefdoms) along the way.<p>Keep in mind, there&#x27;s not this one magical system that keeps things going that by getting a bunch of really smart guys will right itself.<p>Often times, it&#x27;s a combination of COTS and custom software that has grown organically over the years.<p>So take for example, one of my previous projects, which was to spin up new IT for a PE spinoff. There were over 70 major applications to account for with tons of associated business processes, functionality etc. It was a massive undertaking but yes, it&#x27;s doable.
