Lesson 1
What is e-business architecture?
Architecture is an over-used word in technology and business:
  1. network architecture,
  2. application architecture,
  3. new product architecture
But what is architecture and why is it important to clients?
When a marketing person says:
"We want to give a free book to anyone who purchases ten books with us in a year, using our online service."
A developer will say:
"I get it. If order amount = x, then execute free item routine."
But an architect responds:
"I understand. We want value to be given to an entity when an event is triggered."
Commerce Engine
Architecture is about creating environments, not designing systems. Architects create the environment where disparate systems can operate together.

Lower Future operating costs
The extra effort and expense associated with architecture almost always result in lower downstream operation costs.
They also result in greater stakeholder satisfaction over time. In other words, a well-formulated plan results in smoother execution, and a higher quality product.
Brick and Mortar
Relevance to KPMG
Companies looking for profitability and growth in the e-Business sector often require high value e-engineering solutions. Architecture is a process that enables KPMG to differentiate its services.u
Terms and Definitions
  1. Pattern: A pattern is an archetypal interaction, such as stimulus-->response. Natural patterns exist throughout the world, independent but often interconnected to social structures and or business goals.
  2. Elements: Those atomic parts of a solution that when put together, derive a solution. The problem might be, "I need to hang a painting." In this situation, the hammer, nail, and the human action of swinging the hammer are elements of the solution (a nicely hung picture).
  3. Real-world components: Those physical entities that when put together bring about a solution.
  4. Problem space: The defined area in which an architect works. For example, a painter's problem space would include: The landscape, her canvas, paints, and brushes. In e-Commerce, the problem space is often large and immensely complicated.
  5. Form: The layout (map) of how the problem space is organized. For example, a blueprint of a kitchen's layout.
  6. Function: The activities (function) that occur within a defined problem space (form). For example, the kitchen (form) is laid out in particular way that supports cooking (function).
  7. Stakeholder: Anyone who has a material interest in the outcome of a solution's implementation.
  8. Emergent patterns: Those patterns which naturally emerge from the ongoing processes and practices of a system. For example, a business might find that customers are not using their online banking service because they find it easier to walk into the brick and mortar bank.
