2.11 Sources of Knowledge

Literature includes textbooks, user manuals, and supplier documentation. These sources provide structured, detailed, and technical information that supports learning and correct use of digital systems.

Professionals such as managers, colleagues, and conference speakers provide practical knowledge based on experience. These sources are valuable for sharing best practice and real‑world problem‑solving.

Websites such as wikis, blogs, and forums offer easily accessible information and community support. They are commonly used to find solutions but require careful evaluation of reliability.

Media sources include social media, podcasts, and videos. These formats often present information in an engaging way but may vary in accuracy and depth.

Observation involves gaining knowledge through dashboards, system monitoring tools, and physical inspections. This source provides direct and real‑time insight into system behaviour.

The reliability and validity of a source may be affected by:

• Bias or subjectivity – personal opinions may influence content
• Evidence or expertise – whether the author has relevant knowledge
• Publication date – older sources may contain outdated information

Corroboration involves checking information against multiple independent sources. This increases confidence in accuracy and reduces the risk of relying on incorrect information.

Making judgements about sources of knowledge requires evaluating reliability, validity, and relevance. Professional and peer‑reviewed sources are often more reliable, while informal sources may need verification through corroboration.
