What is Enterprise Map?Enterprise Map Training
A identity and low hanging fruit of EA
Enterprise Map is a graphical EA approach to enable the Enterprise on architecture drawing similar to the traditional architects. The result is a tangible Enterprise Architecture which is intuitive for every one to comprehend. Enterprise map is the light Enterprise Architecture approach compare to the heavy duty effort of complicate enterprise modeling and analysis. Enterprise map is the tip of the Enterprise Architecture iceberg which provide an tangible EA and lead industry to the massive enterprise knowledge. The Enterprise map does not only establish the identify of EA but also a low hanging fruit of Enterprise Architecture.
The Enterprise map visualize the
. Business layer
. The application layer
. The data layer
. The technology layer.
Enterprise map the As-is environment and the target environment.
Enterprise map method does not only used to map the As-is environment but also the target enterprise environment. Initially, it is used to plan the target IT environment, in a advance EA approach it is is also used to transform the entire business.
What is an Enterprise Map?
Enterprise Map renders the holistic Enterprise business and automation environment for every one to comprehend. To know an Enterprise people like to know :
What you do?
Who are you?
What you do?
How you do it?
Where are you located?
What is your organization look like?
The organizations around you?
Your automation environment?
The Enterprise Map takes all the frequent ask question about the enterprise into account and orderly arrange them in an one page approach as shown in the following figure which also serve a the reading guide for an Enterprise Map.
Enterprise Map provide the enterprise business overview with location, organization, concept of operation and value chain to introduce the Enterprise at a holistic and high level overview; To address the question of what you do, the Enterprise Map lay out their business function similar to a floor plan, it is not just a function list. The business floor is the framework of what they do.
The next thing people want to know is “How you do it?”. EA map identify the work flow between each room and the high level business process in each room. In addition to business function and process, people become curious on the automation system in the enterprise. It is similar to the furniture in the house. EA map use the bubble icon to represent application systems used in the business process along with associate database. EA map present technology with technology patterns in different color as specified in the legend.
In addition to the Enterprise itself, it is also important to show how the Enterprise interact with external organization. EA map reserve the bottom part to lay out the supporting organizations.
Enterprise Map is not process centric
Enterprise Architecture is not business process centric as the Enterprise Map approach by Burton, Herbert O, Pennotti, Michael C.. Business process modeling and optimization has been the major concern in the information age of automation. However, it takes more attributes than business process to define an Enterprise. The popular Zachman framework describe the Enterprise from the aspect of What? How? Who? When? Where? and Why?
Give a second thought, business processes realy do not define Enterprise, they are the process solution to support enterprise business goal rather then the definition of an Enterprise. We all know that business process must be reengineered to take advantage of technology evolution.
Enterprise Map become sensitive information
The Enterprise should secure their Enterprise Map, although the Enterprise Map can be created from many pieces of non-sensitive information, but "The sum is much greater tha parts", by putting together the non-sensitive information in the proper order, it will become sensitive information to the enterprise.
WHAT IS NOT Enterprise Map?
Enterprise Map is not a business process or activity model Enterprise Map is not a conventional business processes or activity model in the traditional EA. The application development trained IT professional have been business process centric and more likely to confuse EA topology with business processes or activity model. The EA topology describe the enterprise mission and definition rather than business process model.
Enterprise Map is not the enterprise inventory EA map is very different from inventory the exiting environment. EA map is a mapping effort to orderly arrange all the parts and map the overall relation to render the enterprise big picture. The wikipedia describe that the word inventory was first recorded in 1601. The French term inventaire, or "detailed list of goods," dates back to 1415. Inventory management is primarily about specifying the size and placement of stocked goods. Inventory management is required at different locations within a facility or within multiple locations of a supply network to protect the regular and planned course of production against the random disturbance of running out of materials or goods.
Enterprise Map is not art work EA Map is not only a pretty picture or a piece of arts as many people suggested. The EA community must establish a repeatable Enterprise Map approach which will become a major discipline of Enterprise Architects in the say way as the discipline of Engineering survey. EA is an emerging discipline, the capability to develop enterprise map distinguish Enterprise Architects from other discipline.
The Enterprise Map Framework
The Enterprise Map Framework lay out overall activitis to compose the Enterprise map. The vertical side list the Enterprise Map layers whcih does not only include the business architecture but also shows how business take advantage of automation systems.
The following Enterprise Maps framework describe the approach.
