Suppose Mr. A says, ā€œX is not available.ā€ Is it universally ā€œX is uselessā€?

  • If so, then the perception that ā€œX is not availableā€ would be shared.
  • Unless you have a very limited opportunity to try out X to see if you can use it. There are those who can use X and those who cannot, and Mr. A is the latter.

ā€˜Usableā€™ is Attributes of relationships rather than single attributes.

  • Relationship between tools and users, challenges and solutions

  • Only ā€œusableā€ when well matched.

  • Useless.
