Enterprise Modeling
Introduction
Enterprise Architecture (EA) is a Global approach which coordinates evolutions of independent domains like Transformation of Organization, Process Modeling, Master Data management, human resource management, Information Systems, and Transformation methodologies to provide a competitive advantage to the Enterprise.
Enterprise Architecture has two main parts:
• A static part: description of how the Enterprise works through the Enterprise Model which covers Actors (Organization with people and computers), Actions (Processes and Functions) and Information
• A dynamic part: how to transform the Enterprise, which means defining a Target Model in line with Enterprise Strategy and then moving to it.
EA has become key for the Enterprise: Agility and time to market, productivity, capacity to better understand the Customer and extend its services, reduction of useless complexity, and Synergies between Companies of the same Group, are all impacted by EA.
CEISAR delivers ongoing EA white papers on topics chosen by its Sponsors.
To guarantee the consistency of these white papers, CEISAR must use the same language to describe the Enterprise, its Processes, its Organization, its Information System, its EA Governance, its Methodologies.
This document describes this reusable language. It proposes definitions for:
• the Enterprise with different levels: Group, Company, Business Unit
• Actions like Processes and Functions
• Actors who execute the Actions: People can be Actors, but computers may also be Actors
• Information as master Data shared by different Processes
• Organization of the Enterprise
Then the Enterprise is described according to 3 main dimensions:
• Complexity: Real World Execution is separated from its Model; a Global Model helps understand how the Enterprise works thanks to global maps of Processes, Solutions, Functions, Services, Entities; a Detailed Model describes instructions given to Actors through documentation or software
• Agility: Processes are broken down into Operation Processes and Transformation Processes (like Projects)
• Synergy: we focus on Shared and Reusable Elements which are key to giving an efficient structure to Enterprise Architecture.
These 3 dimensions can be represented as an "Enterprise Cube" which helps to sort the many different EA elements: from description of EA Governance to Data Model or Transformation Tools.
Then, we conclude by mapping the CEISAR Model with other existing Models like: Cobit, MIT Sloan Center, and TOGAF.
Most of the concepts developped on this website are further developped in our white papers. You can download any white paper freely. Please do not re-use without explicit permission.
