What are the factors that make system difficult to use ?
Factors that make system difficult to use are :
- Use of Jargon:
- Issue: The system uses weird words that people don’t usually use, like “filespec” or “abend.”
- Problem: Learning the system feels like learning a new language.
- Non-Obvious Design:
- Issue: Some parts of the system are not easy to figure out, and you might not see immediate results.
- Problem: It’s hard to understand how the system works because important details are not clear.
- Fine Distinctions:
- Issue: Small differences in actions can lead to different results, and it’s tough to keep track of these tiny details.
- Problem: People might get confused because similar actions don’t always produce the same outcome.
- Design Inconsistency:
- Issue: The same action might have different names, or one command might do different things.
- Problem: Learning the system becomes like memorizing random information, making it hard to understand the logic behind it.
