Architectural comparison of TCM and PMBOK

Architecture refers ‘carefully designed structure of something’, and here it is about the Total Cost Management (TCM) framework. As the name suggests, the focus of TCM framework is cost management of projects and the deliverable of projects (assets). There lies the fundamental difference between the Project Management Body of Knowledge (PMBOK) by PMI, USA and the TCM framework.  PMBOK focuses on the entire gamut of project management where as the focus of TCM is on total cost management of the project, and the product of the project which is known as the ‘asset’ in TCM jargon.

The PDCA cycle (Plan, Do, Check, Act) by Deming is the underlying theme of management. Whatever we intend to do must be planned first. Then the plan is executed. The progress is checked periodically. Actions are taken if there is a variance. The underlying theme of TCM is also PDCA (recursive PDCA cycles).
