Very cumbersome to

“Beskriv grunn” is
this the reason for
desired change, or
has it anything to do
with changing one
parameter to another
(like grunnbeløp)
“Gjenlevende
partner”
Is misleading

Heuristic/problem
The use of
“nedtrekksliste”/
drop down menu
may be misleading.
How do you press
the arrow to the

obvious that you
have to press the

Possible solution
This interaction
form is best suited
for direct
manipulation such
as mouse or pen.
You cannot
manipulate the
scrollbar directly.
Show buttons

Possible solution
Users will not
necessarily find this
submenu. Not
intuitive to go from
the menu to the
submenu.
H7 H7
Positive that you
can get help for
each field.
When you first
know about this
sub-menu it is easy
to use.
More investigations
into icons are
required.
Overall consistency
Need for explanation
of the icons, and
possible better icons.
Eg. it is not easy to
recognize the last
icon. Green icon
looks like a play
button 90 degrees
tilted. The delete
icon looks like
backspace, ie
deletion of one
single character, but
it deletes all the
characters in the
field
OK
Not possible to see
which of the two red
tabs that is active.
H7 H7
Use something
similar to tool-tips.
Make the active tab
larger than the other
tabs.
Arrow showing
progression could
be useful.
Make use of more
colors.
The text does not
inform you that you
have to evaluate and
send. You have to go
through the whole
setup before you
discover that it is not
evaluated.
Since evaluate and
send form is only
used in this screen it
would be better to
only show this in the
last screen.
There is no heading
on this page.
After sending, last page. The program is
finished, but there is
no way to end the
program.
General problems
