Managing Enterprise Architecture Change

.1 Triad Of Enterprise Architecture

- There are three dimensions of the EA should be considered: BRP, IT and organizational strategies

- Business processes, Technical architecture and organization structure have immediate impact on the customers, so the consequences of any modifications in those main components will affect the business position in the market.

.2 Basic Strategy

The architecture is putting all information needed together for future planning to choose the path advantageous position in the market .

The basic strategies steps are :

·         Suggestions

·         Synthesis

·         Acceptance

o   If synthesis is accepted it will be a strategy

o   If it’s not the analysis will occur to find out the synthesis

.3 Emergent properties of complex systems

The quality of an architecture reflected by addressing its non-functional indicators:

·         Openness

·         Performance

·         Evolvability

·         Security

·         Maintainability

·         Reliability

.4 Traditional Separate Architectures Approach:

There are 4 types of architectures in an organization :Technical , application , information and business give you the overall picture of an organization by providing  a contemplated abstract concept of how the whole system works , not just physical things .  

.5 Centralized Architecture Repository

Architecture repository is the important element in any architecture it should content all important elements in the system in any level of details.

.6 The Five Steps

The way to manage the risks correlated with complex systems is through architecture based approach the below steps allow the EA designers and strategists to predict and control the emergent properties.

1.       Audit

2.       Populate

3.       Analyze

4.       Visualize

5.       Optimize
