Study Notes

Identification

Software quality is the degree to which a software product meets the requirements.
Software quality assurance defines and assesses the adequacy of software processes to ensure confidence in producing suitable quality software.
Software developers and organisations rely on their reputation. Software bugs can have immediate impacts on clients and customers.
Poor quality software is expensive to develop and maintain (technical debt).
Software certification may be required, often requiring evidence of quality control and assessment measures.
Legal obligations may apply to organisations using the software.
Ethical codes of practice may apply if software isn't covered by certification or legislation (and isn't safety-critical).
Software prototyping builds prototypes to display functionality, but may not use the original software's logic.

Software Prototyping

Allow users to evaluate the software system design and how the software actually works.
Clarify the functionalities of the software to both users and developers.
Reduce costs and time compared to building and repeatedly modifying a software product.
Reduce the need for recreating the software system due to gaps in implementation.
Throwaway Prototyping: A fast method where prototypes are created and discarded after testing.
Evolutionary Prototyping: Prototypes are reused and refined following testing.
Fidelity Prototypes: Vary in level of detail (low-fidelity to high-fidelity) showing the visual appearance and user flows (low-fidelity) and actual usage by real users (high-fidelity)
Paper-Based Prototyping: Used for creating user interface prototypes using hand drawings.
Wireframing: Visual representation of a product page to arrange user interfaces for software.

Software Inspection/Review

Software artifacts include requirements, source code, user documentation and test plans.
Fagan inspection methodology aims to identify and remove errors in software products and identify systematic defects in processes.
Roles include: Moderator (leads inspection team), Author (responsible for the artefact), Reader (subject matter expert) and Tester (runs test cases).
Structured walkthrough: A peer review involving the developer bringing reviewers through a deliverable.
Code reviewing compares code with fellow programmers to identify faults and ensure quality.
Tool-driven code review uses automated tools to identify problems in source code.
Developer-driven code review assesses code quality manually.
Modern code review uses less formal methods than inspections, deploying tools for streamlined development processes.
Pull-based development is a modern approach where code review happens in an integrated code platform using "pull requests."

Enterprise Architecture Modeling

Knowledge Representation: Shows how an enterprise architecture model is depicted and perceived by individuals.
Knowledge Goals: Goals used in the modeling process.
Knowledge State: Condition and commitment of stakeholders regarding enterprise architecture.
Knowledge Transformation: Process of knowledge being transformed following the implementation of the enterprise architecture model.
Central Representations: Primary and essential models used when changing knowledge.
Modeling Activities:
- Establish purpose, scope and focus for the model.
- Select one or more viewpoints for the model.
- Create and structure the model to meet enterprise documentation needs.
- Visualize the model while considering stakeholders and their needs.
- Use the model for communication and evaluation of model effectiveness against intended goals.
- Validate the model to ensure agreement among key stakeholders.
- Gain commitment of stakeholders concerning the implications of the model implementation.
- Disseminate pertinent information about the model.
- Maintain model up-to-date.

Modelling Actions

Introduce a candidate element
Refine an element
Abandon a model element
Abstract a concept or relationship
