Study Notes

Process and Product Standards

Process standards encompass descriptions of specification, design, validation procedures, and related documentation throughout development stages.
Product standards apply specifically to the software being developed and include document and coding standards, which dictate format and language usage.
Key process standards include design review conduct, software submission procedures, versioning, project plan approval processes, change management, and trial recording protocols.
Product standards address requirements document structures, comment header formats, programming language guidelines (e.g., Java), project plan formats, and change request forms.

Difficulties with Standards

Standards may be viewed as outdated and irrelevant by software engineers.
Engineers often face excessive paperwork, complicating compliance with standards.
A lack of supporting software tools can lead to cumbersome documentation management.

Quality Management and Conflicts

Systems can't be optimized for all quality characteristics; improving one aspect may diminish another (e.g., robustness vs. performance).
Quality plans should identify crucial characteristics and detail quality assessment processes.
The quality of the production process significantly impacts the final product quality, highlighting the intricacies of software development practices.

Quality Culture

Establishing a "quality culture" is essential for high product quality in development teams.
Teams should take responsibility for their work quality and propose innovative improvement ideas, fostering professionalism.

Importance of Standards

Standards define requisite qualities for methods or products and are vital to quality management.
They can be organizational, national, international, or specific to projects.
Best practices prevent past mistakes, define organizational quality, and help new employees orient themselves.

Agile Development Approach

Agile development emphasizes informal quality management, fostering a culture of accountability within teams.
Agile avoids administrative burdens from traditional standards-based methods like ISO 9001.
Common practices include self-organized code reviews, strict adherence to build integrity before check-in, immediate issue resolution, and tracking various metrics related to code quality and system performance.

Measurement Methods and Issues

Metrics are vital for quantifying system quality attributes and identifying poor-quality components.
Assumptions for metrics assert that internal characteristics can be measured, while external characteristics often matter more, complicating the connection between metrics and perceived quality.
Industry measurement challenges include assessing ROI on metrics programs, lack of standardized procedures, and variability in processes making measurement difficult.

Empirical Software Engineering

This field relies on software measurement and metrics to validate assumptions about engineering approaches through experiments and data collection.
Despite its foundation in empirical research, practical impacts on software engineering practice remain limited.

Product Measurements

Predictive quality metrics assess product quality, with classes including static metrics derived from system representation evaluations.
