essence kernel-based enterprise method architecture
DESCRIPTION
This presentation was given by Professor June Sung Park in Korea Advanced Institute of Science and Technology, Chairman of SEMAT Executive Committee, in the Essence Information Day held in OMG Technical Meeting in Berlin, Germany on June 20, 2013. The presentation illustrates how one can standardize and integrate a variety of software engineering methods used in an enterprise by expressing all practices and methods in terms of the Essence kernel.TRANSCRIPT

Enterprise Method Architecture
4
Understand all methods used in an enterprise
Analyze their relationships
Minimize, standardize, integrate and share the set of methods
Enterprise Method Architecture
Method
Is a federation of
Example: US DoD
5
Do methods produce consistent models across different views (e.g. across process, information, use case)?
Do methods produce models traceable across different abstraction levels?
Example: DoDAF Meta Model (DM2)
6
Define concepts and models usable in DoD’s 6 core processes:
– Capabilities Integration and Development (JCIDS)
– Planning, Programming, Budgeting, and Execution (PPBE)
– Acquisition System (DAS)
– Systems Engineering (SE)
– Operations Planning
– Capabilities Portfolio Management (CPM)
Establish guidance for architecture content as a function of purpose
Make DM2 so the architectures can be integrated, analyzed, and evaluated to mathematical precision
Establish and define the constrained vocabulary for description and discourse about DoDAF models and their usage in the 6 core processes
Specify the semantics and format for federated EA data exchange between architecture development and analysis tools and architecture databases
Support discovery and understandability of EA data:
– Discovery of EA data using DM2 categories of information
– Understandability of EA data using DM2’s precise semantics

Conclusion
We need to build a library of practices using the common kernel,
not just for software engineering, but also for other disciplines essential for business-IT alignment
We need to develop an easy-to-use tool to compose practices into a method, and a marketplace where global best practices can be traded.
We need to produce success cases of developing and managing Enterprise Method Architectures based on Essence.
We need to extend the kernel to accommodate ever expanding use cases and technologies of software.
