64 Chambers of Enterprise Architecture Development: Explore the Success Formula of Enterprise Architecture
Harmony Classification Framework has developed a simple, 64-celled kaleidoscope to experience the beauty of the enterprise architecture and a step-by-step success pattern building the enterprise called the ’preventive enterprise‘. Last issue I detailed ‘Chamber 0’, the meditation chamber that will help you to stabilise your enterprise mind and facilitate the understanding of the enterprise. This issue unravels the 64 most powerful chambers of Harmony Classification Framework.
Enterprise Architecture Hieroglyphic
The last issue of the column introduced the concepts of enterprise hieroglyphic. Enterprise Hieroglyphic could convey very useful messages through the image anchors. This week we will introduce 16 more hieroglyphics for each of the 8 rows and 8 columns of the Harmony classification framework as described in Figure 1 and Figure 2:


Harmony, the Classification Framework: The Ultimate Solution Board for Enterprise Puzzles Game
The last issues explained the different aspects of the Harmony, the Enterprise Classification Framework. There are certain simple playing rules for this board game. These 64 Harmony chambers are full of treasures; it starts with an empty box and finishes with a box full of enterprise treasures, which is called the ‘information rich enterprise architecture foundation’. See Figure 3.

However each of these 64 treasure chambers needs to be evaluated in terms of economic benefits, by using different economic value analysis techniques introduced in our MDA Radar Issue called MEASURE. The following two figures (Figure 4 and Figure 5) are self-explanatory and explains the simple rules for Harmony Enterprise Classification Framework.


The eighth column of the Harmony, introduces another enterprise best practice concept, called Reusable Asset Management. Harmony resonates the scope of the Reusable Asset Specification by OMG, Version 2.2, formal/05-11-02. “The scope of this Specification is a set of guidelines and recommendations about the structure, content, and descriptions of reusable software assets. We recognize that there are different categories of reusable software assets. The specification identifies some categories, or rather types or profiles and provides general guidelines on these profiles. The Reusable Asset Specification (RAS) addresses the engineering elements of reuse. It attempts to reduce the friction associated with reuse transactions through consistent, standard packaging. This is much like the steering wheel, turn signals, pedals, and fuel gauge in a car: although they’re slightly different across car models and makes, there’s a familiarity among them that significantly reduces the costs of reuse” [OMG Reusable Asset Spec]. See Figure 6.

64 Treasure Chambers of Enterprise Best Practices
These eight tables shows you the type of enterprise artefacts, recommended by Harmony Classification Framework to demystify different aspects of enterprise puzzles. However, some of these artefacts may not be applicable for specific type of enterprise problems. At the same time your enterprise may discover few other relevant artefacts, which may not be included in these lists. These lists of artefacts are therefore an excellent source for your enterprise architecture development phase.








The next issue of MDA Radar will explain how this Harmony Classification framework helps you to populate the required artefacts suggested by TOGAF, IEEE 1471-2000, ISO 9126, MDA and RM-ODP.
