Web Systems which affect relationships

   Relationships can be effective or not effective.

      Organisatio                          Organisatio
      n                                    n

                    Relationship
                                        Relationship

                        Web Service
                    A Story

   A colleague borrows a book
                                     Trust can be a
                                         source
                                  of productivity, or a
   A student borrows a book           measure of
                                     organizational
                                         health!
   A third colleague borrows a book
                Trust as the key

   Three definitions of trust:

1. We can think of trust as a quality of a relationship
   which substitutes for security
                                           Trust as neg-
2. Or, we can propose that there is        ative
   no compromise of security even          security?
                                           Risky idea!
   when trust is in play.
 Uncompromising Definitions of Trust

1. Given that there are:
 ➢   Risks (conditions which must be prevented), and
 ➢   Service agreements (conditions which must be met),

     We could say that any service which prevents the
     risks and facilitates the services is satisfactory. Trust
     is maximizing services subject to avoiding all risks.

2. Alternatively, assuming that security rules are in
   place, trust is actually about the mechanism:
   maximizing flexibility and convenience.
    Optimistic Definition of Trust

   If security is identifying bad things and preventing
    them from happening,



   Trust is identifying good things and helping them to
    happen.
         Trust has several meanings

   The concept that trust is a quality of human
    relationships is still important.

   Trust as a quality of a relationship between
    humans and systems is also important, and
    similar to human trust.

   Trust as a quality of the mechanisms for
    delivering services is unintuitive – but may be a
    powerful idea.
