In the State of Washington, cost modeling is done in accordance with the adopted taxonomy and starts with modeling costs to the technology towers. TBM Program technology towers are key to the foundation and support moving to the next level of maturity which entails modeling costs to the applications, business services and business capabilities.
Washington state TBM Program journey started in 2012. The program encountered and overcame several challenges during the early years. Leveraging lessons learned, in 2016 the community supported a program "reboot" that was more centered on a strategic approach resulting in increased value. Following are published articles on navigating TBM Program changes and capturing value in Washington state.
To facilitate communication and gain alignment between IT, Finance and Business areas we recognized a common language or taxonomy was needed. The program initially used a "custom" taxonomy to identify pools of cost and technologies which resulted in everyone speaking a common language however led to missed opportunities in executive level reporting. To close the gap on the reporting, beginning fiscal year 2017 the program moved to industry standard TBM Taxonomy that’s governed and maintained by the TBM Council Board Committee on Standards.
Our goals for Fiscal Year 2018-2019, focus on improved foundational work to better align infrastructure and application data out to the delivery of business services.
The TBM Program monitors statewide IT spend by capturing data on new expenditures (IT Acquisitions), ongoing expenditures (Maintenance and Operations) and spend between agencies (EL Charges - Data Processing InterAgency).
TBM is a set of best practices for running IT like a business to effectively and consistently communicate the cost of IT along with the business services IT provides. The primary goal of TBM is to provide the ability of IT and business leaders to have data-driven discussions about cost and value of IT to best support business goals.
