1. Origins of Defects (Root Causes)
Defects are typically injected during the development lifecycle due to human error. The main sources include:
Education/Skill Gaps: Developers lack knowledge of a programming language, algorithm, or technology (e.g., misunderstood operator precedence).
Communication Gaps: Inadequate information transfer between stakeholders, analysts, designers, and developers, leading to misunderstandings of requirements.
Oversight: A developer forgets to do something, such as initializing a variable or adding a null check.
Transcription Errors: The developer knows what to do but makes a mistake while typing, such as misspelling a variable name.
Process Issues: Inadequate time allowed for design or review, leading to rushed work.
Bad Fixes: Fixing a defect introduces new, unforeseen bugs.
