Description

This subject teaches students current industry practices to design, develop and evaluate software architecture meeting predefined quality characteristics of functionality (suitability, security), usability (operability), efficiency (time behaviour, resource utilisation) and maintainability (changeability, testability). Concepts, theories and technologies underlying the methods and techniques are introduced and explained as required. Students apply the industry practices that they have learned to develop an architecture of a business system.

Subject learning objectives (SLOs)

Upon successful completion of this subject students should be able to:

1. Describe the factors that affect the architectural context and requirements, including stakeholders and their interests, architectural qualities, business requirements and usage scenarios. (B.1)
2. Develop and refine multiple views of a software system architecture, based on the conceptual, execution and implementation architecture. (D.1)
3. Understand the key issues in choosing and implementing architectural patterns, including performance, testing, security, usability, maintainability and reliability qualities. (D.1)
4. Reason about alternative architectural designs to satisfy a system's quality attributes. (C.1)
5. Develop a complete software architecture for a proposed solution to a realistic industry problem. (C.1)

Course intended learning outcomes (CILOs)

This subject also contributes specifically to the development of the following Course Intended Learning Outcomes (CILOs):

  • Socially Responsible: FEIT graduates identify, engage, interpret and analyse stakeholder needs and cultural perspectives, establish priorities and goals, and identify constraints, uncertainties and risks (social, ethical, cultural, legislative, environmental, economics etc.) to define the system requirements. (B.1)
  • Design Oriented: FEIT graduates apply problem solving, design and decision-making methodologies to develop components, systems and processes to meet specified requirements. (C.1)
  • Technically Proficient: FEIT graduates apply abstraction, mathematics and discipline fundamentals, software, tools and techniques to evaluate, implement and operate systems. (D.1)

Contribution to the development of graduate attributes

Engineers Australia Stage 1 Competencies

This subject contributes to the development of the following Engineers Australia Stage 1 Competencies:

  • 1.3. In-depth understanding of specialist bodies of knowledge within the engineering discipline.
  • 1.5. Knowledge of engineering design practice and contextual factors impacting the engineering discipline.
  • 2.3. Application of systematic engineering synthesis and design processes.

Teaching and learning strategies

This subject is taught through facilitated self-learning. All lectures and related material are available online and may be viewed at the student's convenience. Quizzes are provided to enable the student test their understanding and application of knowledge about software architecture.

Students are expected to have studied the tutorial topics in preparation for tutorials. During the first half of the semester the tutorials will demonstrate the topic through application to a problem, followed by student evaluation of the application. Then students will perform an exercise and evaluate each other's work in order to develop their skills in collegial review and ability to identify where an architecture might fail.

During the second half of the semester students will be working on their major assignment. During tutorials each team will present to another team the architecture stage they have developed. The reviewing team will evaluate the presented architecture stage to acknowledge what has been done well, and where the proposed might fail. The review feedback will be communicated to the presenting team as soon as possible after the presentation.
