The ABC Cycle 2

Introduction

“S/w architecture in turn affects the technical , business,

social environments that subsequently influence

future architectures. This is known as cycle of

influences;

from the environment to architecture & back to the

environment, the Architecture Business Cycle(ABC).”

The ABC Cycle 3

• The relationships among business goals, product requirement & architecture form a cycle with feedback loop that used to handle growth & system growth.

• • Architecture Business Cycle (ABC)

“Architecture Business Cycle (ABC) is description of a system, used to represent relationship among structures/ components of the system to the environment in which the system is developed and implemented.”

- Shahid Hussain (ABC for embedded system)is description of a system, used to represent relationship among structures/ components of the system to the environment in which the system is developed and implemented.

The ABC Cycle 4

Where do Architectures come from?

Architectures are influenced-• By system stakeholders.• By the developing organization.• By the experience of the architect.• By the technical environment.

The ABC Cycle 7

The architecture affects the factors that influence them(Cycle works as):-

The architecture affects the –• Structure of the developing organization.• Goals of the developing of the organization.• Customer requirements with reusability.• The process of the system building will affect the

architect’s experience with subsequent systems .

The ABC Cycle 8

Architecture business cycle changes-

– Organization goals to requirement.– Requirement to architecture.– Architecture to systems.– Systems to organization.

Influences -– Technical, business , social.– Stakeholders, other source.

The ABC Cycle 9

ABC activities includes

• Create the business case.• Understand the requirement.• Create the architecture.• Document & communicate the architecture.• Analyze the architecture.• Implement the system based on architecture.• Conforms the implementation.

The ABC Cycle 10

“The cycle worked well as a guiding model to understand the role of the architecture in the software development process.”

“Presents theoretical & practical benefits.”-Carl Magnus Olsson (Case Study of ABC)

The ABC Cycle 11

Qualities of a Good Architecture

With in the “ABC” , architect produces architecture & that should be-

– the product of one or many architects– well documented– circulated to the system’s stakeholders– fulfill all the customer’s requirements– analyzed and evaluated for quality attributes– incremental
