RCA Institute Special Report:  Evaluation of Technology Business Management Council's Cost Modeling Guidance

The RCA Institute has completed a review of the TBM Council's Taxonomy that serves as the basis for building cost models of IT functions in organizations.  The review was based on the Institute of Management Accountants Statement on Management Accounting:  Costing System Attributes that Support Good Decision Making.  The review finds the TBM Taxonomy provides a framework that can improve cost information to some extent, but falls short in its claims about consumption, performance, and optimization because it does not provide enough guidance to ensure it's cost model is built on a solid operational foundation of causality based on resources, processes, and capacity.

Watch an interesting discussion on TBM Council's approach to modeling IT resources and costs to make them more visible and manageable throughout the organization. RCA expert Anton van der Merwe, Alta Via Consulting, and TBM author, Todd Tucker discuss a wide range of IT management and cost modeling issues.

RCA Education by Webcast

The RCA Institute is producing a series of pre-recorded webcasts that will provide an introduction to Resource Consumption Accounting.  Five introductory webcasts are now available on the RCA Institute You Tube Channel. The topics are:

The Institute of Management Accountant's Conceptual Framework for Managerial Costing

In September 2014, the IMA published its Conceptual Framework for Managerial Costing (CFMC) that established clear principles, concepts, and constraints for creating cost information purely for internal decision support. RCA is the most comprehensive approach to implementing the CFMC. In July 2019, a follow on Statement of Management Accounting, Costing System Attributes that Support Good Decision Making, provides practical guidance on applying the principle of causality and the concepts for building effective cost models for internal decision support. The SMA Developing an Effective Managerial Costing Model provides a process to create cost information for internal decision support.  These documents are aligned with the RCA approach to modeling and internal decision support information.
