Dear God, please let me find a bowl of peanuts next time, not these stinky popery.
Enterprise Architecture: Enterprise Context Model (ECM) example
See my first posting for a brief explanation on what ECM is.
Here is an ECM of a fictional company called Techie Princesa Bakery Corporation.
Consider that this corporation has “Always Eat Healthy” Program and they are developing a new gluten-free menu. Perhaps Tim Hortons should come up with some gluten-free muffins and donuts. Sounds like a good idea to me, no? 😉
Enterprise Architecture: Technology Architecture
What is Technology Architecture (TA)?
- A domain of Enterprise Architecture
- Concerned with the technology that supports the systems that are in use in the organization – both software and hardware technology
- Describes the software and hardware capabilities that are required to support the deployment of business, data, and application services
- Includes but not limited to IT infrastructure, networks, middleware, communications.
Enterprise Architecture is…
“a coherent whole of principles, methods, and models that are used in the design and realization of an enterprise’s organizational structure, business processes, information systems, and infrastructure”. (The ArchiMate Foundation)
Enterprise Architecture: Enterprise Context Model (ECM)
When trying to define a business, it is critical to understand the context of the business such as the following to ensure that those who are involved have a clear understanding of the business, their roles and responsibilities.
- Mandate
- Objectives
- Key stakeholders (organizations and/or individuals) and the relationships
- Accountability relationships with stakeholders
Enterprise Context Model (ECM) is a Business Architecture artifact that provides a single view of the key stakeholders involved in the business. It also establishes a framework to further breakdown and understand the business.
Here is my attempt to come up with an ECM for City of Edmonton’s Graffiti Management Program.
Refer to “Architecture for the Business – By the Business” presentation by I&IT (Office of the Corporate Chief Technology Office) if you are interested in learning more about Business Architecture and ECM.
A woman is often measured…
Stumbled upon this Nike ad today. Love it!
“A woman is often measured by the things she cannot control. She is measured by the way her body curves or doesn’t curve. By where she is flat or straight or round. She is measured by 36-24-36 and inches and ages and numbers. By all the outside things that don’t ever add up to who she is on the inside. And so if a woman is to be measured, let her be measured by the things she can control, by who she is and who she is trying to become because as every woman knows, measurements are only statistics, and statistics lie.”
Enterprise Architecture: Conceptual Data Model
Here is a Conceptual Data Model that I produced for an Enterprise Architecture Certification course I took at University of Toronto. My attempt was to create a Conceptual Data model: Entity Relationship Diagram for City of Edmonton’s Graffiti Management Program, based on the information I found on their program website.
