Yet another definition of enterprise architecture #entarch and metrics for enterprise architects

My short definition of #entarch from the viewpoint of an enterprise architect

Enterprise Architecture (EA) is a system-thinking applied management discipline about essential decisions for coordinating people, processes, projects and products in 11 dimensions:

1. focus space (biz unit, enterprise, country, etc.)
2. architectural space (business, information, etc.)
3. time span (project life-cycle, solution life-cycle, enterprise life-cycle, etc.)
4. sector span (various industries)
5. problem space (re-structuring, rationalisation, M&A, standardisation, etc.)
6. solution space (from a concept to operations - like ZF rows)
7. cultural space
8. practice space (are you theoretician vs methodologist vs practitioner?)
9. media space (physical vs analog vs digital)
10. financial space (number of zero in the budget)
11. people space (top, management, middle-management, super-users, workers)

Candidates:

• environment
• legal 
• socio-technical vs technical system
• CX span (touch point, journey, storytelling, lifecycle)
• social space (gender equality, consensus building, conflict resolution)
• person span (individual, house, personal cars, public places, etc.)
• technology ?

Using the definitions below:

• System-thinking applied management discipline is an applied management discipline which uses system-thinking approach.
• Applied management discipline is a management discipline which applies scientific knowledge for solving practical problems.
• Management discipline is a discipline for the better management of the enterprise functioning in support of the enterprise goals.
• Discipline is a coherent set of governing rules.

And the self-contained definition will be:

Enterprise Architecture (EA) is a coherent set of governing rules for the better management of the enterprise functioning in support of the enterprise goals by applying system-thinking scientific knowledge for solving practical problems in coordinating people, processes, projects and products in 11 dimensions.

.......

This definition can be used as a metric to qualify enterprise architects. In my books, an enterprise architect must comply with the following:

1. focus space: work for 1000+ people; 
2. architectural space: able to contribute to all architectural domains; expert knowledge in 2-3 domains
3. time span: have experience with complete enterprise life-cycle
4. sector span: min 5 different sectors experience; able to find similarities between sectors
5. problem space: leading min 3 critical enterprise-wide changes
6. solution space: comfortable in min 4 rows
7. cultural space: know culture specifics for the majority of staff members
8. practice space: be good at least in 1 of these roles
9. media space: make fully digital a whole company (100+ people)
10. financial space: 1 M budget minimum
11. people space: able to talk to everyone to explain how EA will address their concerns and change their working habits for the better
