4.2.1 Wizards
A common type of design tool found on the web is a guided, interactive program that
incorporates relevant guideline information and steps the user through a process to arrive at
a problem solution. Software wizards would fall into this general category.
A simple example of such a tool can be found on the website of PPG Industries (2008). PPG
is a large producer of glass and glazing products. Their website provides considerable
resources to designers in the form of technical bulletins, design guidelines and tools. One of
the tools is called the “Interactive Glass Product Selector,” which is accessed through a link
on the main glass resource webpage. The tool is intended to facilitate the glass selection
process (Figure 4.1 - Figure 4.4).

The user is first directed to make a selection from the “exterior color” box first. Clicking in the box
reveals the drop down menu.
