Jigsaw connector pieces representing tasks to be performed are displayed on
a computer screen, preferably hierarchically in a tree, to elucidate the relationships
between tasks. To perform a task, a user positions an attachment jigsaw piece next
to its corresponding connector piece. The user is then prompted to input or verify
preferences in a properties panel. For example, a printer may be installed by interconnecting
an attachment piece (corresponding to the printer to be installed) next to the
printer connector piece in the tree. The user may be aided in the process of matching
connector and attachment pieces through the use of matching colors and images on
the pieces.
