Distinguish Functionality from Quality Attributes is an excerpt from: Software Architecture in Practice LiveLessons (Video Training): • http://www.informit.com/store/softwar... • 9+ Hours of Video Instruction • Overview • Software Architecture in Practice LiveLessons provides aspiring architects an overview to a broad range of methods, processes, and tools that are essential to managing the complexity of large-scale software. These LiveLessons will provide you with practical, road-tested techniques and advice to help you become a software architect. • Description • In this video training, we begin with an overview of software architecture-what it is, what it isn´t, what it is good for, and how you should represent it. We then look at the requirements (quality attributes) that drive architecture-things like performance, modifiability, security, and so forth. We learn how to elicit, prioritize, and characterize these quality attributes precisely and unambiguously. Then we will talk about the building-blocks of architecture: patterns and tactics. Using this knowledge we will go over a method for architecture design called ADD (Attribute Driven Design). Having designed (or inherited) an architecture, you may want to analyze it, to understand its strengths and weaknesses. To achieve this we present a method called the ATAM (Architecture Tradeoff Analysis Method). Finally we finish up with some practical advice for practicing architects such as: how to blend architect activities with agile methodologies, and how to be an agent for change in an organization. • Skill Level • Intermediate • Advanced • What You Will Learn • What is Software Architecture • Architectural Requirements: Quality Attributes • Architectural Patterns and Tactics • Architecture Design • Architecture Analysis • Architecture in Agile Projects • Who Should Take This Course • Developers looking to go to the next level in their organization and become architects and leaders • Course Requirements • Basic understanding of programming and development • Basic understanding of the software engineering lifecycle and project activities • Lesson 1: What is Software Architecture? • In this lesson you will learn how to define software architecture: what it is (and what it is not) and the implications of this definition. You will also learn the 13 ways in which software architecture is important and the rudiments of documenting an architecture in terms of architectural views. Finally, you will learn about the importance of architectural patterns and tactics, and some rules of thumb on how to distinguish a good architecture. • Lesson 2: Architecture Requirements: Quality Attributes • In this lesson you will learn to distinguish functionality from quality attributes, to unambiguously specify quality attribute requirements, and to recognize other important requirements that drive an architecture. • Lesson 3: Gathering Architectural Requirements • In this lesson you will learn about problems in eliciting actionable architectural requirements and how to remedy this problem via the Quality Attribute Workshop (QAW) and the Quality Attribute Utility Tree. • Lesson 4: Architectural Patterns and Tactics • In this lesson you will be given an introduction to architectural patterns and architectural tactics–the building blocks of design. In addition you will learn how tactics interact with patterns. • Lesson 5: Creating the Architecture Tactics • In this lesson you will learn about a method that aids in designing an architecture: the Attribute-Driven Design (ADD) method. You will be shown a model design problem that walks you through the ADD method. • Lesson 6: Architecture Evaluation • In this lesson you will learn about the forms of architecture evaluation and a specific architecture evaluation method: the Architecture Tradeoff Analysis Method (ATAM). You will learn how to follow the steps of the ATAM and be introduced to a lightweight ATAM variant. • Lesson 7: Architectures in Agile Projects • • In this lesson you will learn about the concepts of Agile and the relationship between agility and architecture. You will also learn some guidelines for Agile architects. • Lesson 8: Epilogue • This lesson provides some final conclusions and you will learn about the value of architecture and how to sell it within an organization.
