Over the last seven years, I have worked as an Operations Researcher and cost estimator on various engineering and planning related efforts. I have provided business operations support through financial analysis, cost estimating, metrics and reporting, risk analysis, quantitative analysis, project management, and client briefing. During this time, I have also become certified as a Certified Cost Estimator/ Analyst (CCEA) with the International Cost Estimating and Analysis Association, a Project Management Professional (PMP) with the Project Management Institute, and have obtained my ITIL Foundations certificate. This paper covers a program management and cost estimating project I supported while with Accenture LLP from 2009 till 2012. The focus of my time with Accenture was spent supporting a client’s data center by building a fractional chargeback model for IT infrastructure and completing calculations for transitioning and virtualizing applications. The model was iteratively updated to incorporate the data center’s architecture changes, as well as modifications to the cost estimating relationships. As a result, the project was able to better perform estimates and complete business cases for applications virtualizing their infrastructure and transitioning into the data center.
