Med minskad komplexitet får ett system ökad användbarhet Fallstudie av användbarhet i ett affärssystem
One of our reasons is that we think the subject usability is interesting, is
that we think it is an important. Usability is maybe the most important element
when you develop or choose a system because it can save money for the companies
and give the users a more delightful and better work environment. The aim of
the investigation is to find out if the implementation of a web portal is a
direction to reach higher usability in a complex system that consists of
several different interacting applications.
The objective of our investigation is to show if the implementation of a web
portal is a direction to reach higher usability in a complex system that
consists of several different interacting applications. In our case we will try
to see if Karlshamns AB:s recently implemented web portal is more useful than
their previous application (Movex with interacting programs)
One thought with the report is to give the system developers a perspective of
how the usability can be in-house made applications versus standard
applications. Also companies that not have any computer- or department for
development and which are thinking of get hold of, change, replace or
complement their system and applications, may have some interest in our thesis.
We have used a qualitative investigation method in our study to answer our
hypothesis. We have interviewed and done empirical studies with concerned
personnel. While the empirical studies we supervised the users when they used
the actual system. To answer our hypothesis we used six questions, which we
come up with after our studies of the literature. When we have analysed the
result from chapter five the conclusion was that our six questions could be
answered in favour of the web portal.
? Has the web portal lower degree of complexity than Movex?
? Is it easier to learn the web portal than Movex?
? Is it easier for the user to remember how the web portal works over the time
than Movex?
? Does the web portal do what it is supposed to do?
? Is the web portal more satisfying to use than Movex?
? Is the web portal more adapted for its usage context than Movex?
The conclusion in our case is that the hypothesis is verified ?With lower
complexity in a system the usability will get higher?.
