What is Architecture?

• Many definitions proposed• CMU SEI: > 30 definitions of Software

Architecture– http://www.sei.cmu.edu/architecture/start/glossary/?location=tertiary-nav&source=217160– Bibliographic Software Architecture Definitions– Community Software Architecture Definitions– Modern Software Architecture Definitions– Published Software Architecture Definitions

ISO/IEC/IEEE 42010

• fundamental concepts or properties of a system in its environment embodied in its elements, relationships, and in the principles of its design and evolution

• Note the distinction between architecture and artifacts.

Open Group

• A formal description of a system, or a detailed plan of the system at component level, to guide its implementaition. (source ISO/IEC 42010:2007)

• The structure of components, their inter-relationships, and the principles and guidelines governing their design and evolution over time.

Business Technology StrategyIt’s the financials…

TCO, CBA, ROI, Payback Period, NPV, Valuation, etc.It’s business strategy innovation & validation

It’s industry concerns, trends, conformance to standards, and compliance

IT Environment

Skills in the functional and procedural aspects of technology organization to ascertain solution and organizational maturity.

It’s how we run things (maintenance & support) and how we create new things (forward engineering).

Quality Attributes

A quality attribute is a non-functional characteristic of a component or a system. It represents a cross-cutting architectural concern for a system or system of systems.

Quality Attributes

IASA Groupings:

• Quality attributes cut across all IT architectural concerns

• Also called systemic qualities, *ilities

• Time, cost, requirement, & resources constraints can become a trade off in applying quality attributes

Usage:• Usability• Localization• Accessibility• Personalization• Customizability

Development:• Manageability• Maintainability• Supportability• Extensibility• Flexibility

Operation:• Performance• Reliability• Availability• Scalability

Security

Quality AttributesMust be measurable, monitored…

…and be practical.

QA Interactions…

Design

Design skills are an architect’s primary tool in delivering architecture strategy and product to the business.

Good design is justifications, reasons, and trade off considerations… it encompasses capturing the decisions made.

Design

Design implies:

Knowledge of methodologies and techniques

Knowledge of tools for design

Knowledge of design artifacts such as patterns, styles, views, and viewpoints

All Design decisions, elements, & artifacts should tie to a business requirement

DesignWhole System Design :

The "whole system" of interconnected elements that participate in, impact, and influence the design process, including the nature and rich tradition of design theory and practice, relevancy of understanding design as a discipline.

The systems sciences, systems theory, and systems thinking; developing “whole systems” perspective and its importance to architects, including recognizing and addressing complex systemic problems and architecture praxis.

Design judgment and the construction of meaning, including work redesign, industry perspectives, and the increasing importance of architectural influence on design.

Human Dynamics

Human Dynamics encompasses the skills associated with managing and influencing people and their interrelationships in the context of an IT project or environment.

Human Dynamics

Attribute What does this really mean?Managing the Culture

Customer Relations

Leadership and Management

Peer Interaction

Collaboration and Negotiation

Presentation Skills

Writing Skills

Politics – understanding of the impact of human culture executing as a culture change agent.

Understanding the psychological dynamics & managing stakeholder & consumer expectations against the business strategy.
