What are the factors that make system difficult to use ?

Factors that make system difficult to use are :

1. 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.
2. 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.
3. 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.
4. 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.
