2. The user interface and interaction

3. The process used to develop the product

4. The capability of an organisation to apply user centred design

DENIM, a Sketch-based Web Site Prototyping Tool

Through a study of web site design practice, the Group for User Interface Research at Berkeley University observed that web site designers design sites at different levels of refinement (site map, storyboard, and individual page) and that designers sketch at all levels during the early stages of design. However, existing web design tools do not support these tasks very well.

Informed by these observations, they created DENIM, a tool that helps web site designers in the early stages of design.

DENIM supports sketching input, allows design at different refinement levels, and unifies the levels through zooming.

Supported platforms:
- Windows 95, 98, Me, NT 4.0, 2000, or XP
- Mac OS X 10.1 (10.0 is not supported)
- Solaris, Linux, and other Unix-like operating systems

Calculating market efficiency and business effects of a web site

If you want to know the market efficiency of a web site, web log analysis can be very effective. But most web analytic software doesn't provide you with easy-to-understand metrics and doesn't take business goals and outcomes such as conversion rates and return on investments into consideration.

At Future Now, an e-business consultancy, you can download a suite of calculators included in an Excel file. The calculators can help you measure the success of a site in terms of a few critical metrics on market efficiency and business effects.
