As I continually work to expand my skill set in IT frameworks for many different enterprise settings, I recently had the opportunity to sit for the ITIL Foundations exam by AXELOS, addressing IT Service Management which I was familiar with from participation in several professional organizations and related studies in other framework areas. While discussing ITSM concepts with other service management experts, the interrelation between these various frameworks became apparent and I have summarized that correlation in the introductory graphic for this post.
All three areas address management and control over IT resources and data delivery, and derive more focused elements from the original Demming model (Plan-Do-Check-Act) from early Quality Control and improvement efforts in Japan following World War II. Demming developed this “PDCA” model from the earlier work of Dr. Shewhart who used “Plan-Do-Study-Act (PDSA)” as a means to define the stages of Statistic Process Control in manufacturing and engineering. Demming’s work in Japan assisted the development of the Japanese post-war economy and he received recognition for his ideas throughout Japan and even in the US and overseas shortly before his death in 1993. The frameworks used for IT Service Management (ITSM), Project (Program and Portfolio) Management (PPP) and IT Governance (ITG) still include Demming’s PDCA model and add layers of abstraction for their particular contribution to the overall enterprise output and capability in turn.
Attempts to address Quality Control via Continuous Improvement procedures in enterprise application of the various control Frameworks and implementation methodologies. All three aspects of IT control have similarities in common that afford points of congruence for adoption and integration of the next methodology in turn, from the abstracted Strategic level down of IT Governance (ITG) through reducing layers of elaboration of Project Management (PM) Tactical level considerations concluding with the least abstracted Operational level of IT Service Management (ITSM).
Through these Frameworks, we can answer the questions, to be explored across the linked articles:
