Common Mistakes
- Using 'decision supporting system' (incorrect participle form).

- Using it as a verb, e.g., 'We need to decision-support this'.

FAQ
Frequently Asked Questions
Not exactly. A DSS is a broader category. Some DSSs use AI components (like machine learning), but many are based on simpler databases, models, and rules. A DSS emphasises aiding a human user, while some AI systems aim for full autonomy.
Primarily professionals and managers in fields like business, healthcare, logistics, finance, and engineering—anywhere complex decisions are made based on large amounts of data.
Typically, a database or knowledge base, a model-based or analytical processing component (the 'engine'), and a user interface that allows decision-makers to interact with the system.
A DSS doesn't 'make' the final decision; it supports the human who does. Its output can be flawed if based on poor data, incorrect models, or biased algorithms. The human user bears ultimate responsibility for the judgment call.
