My comment is in regards to the Human-Centered design process (HCDP).

It seems that there might be a correlation between HCDP and software development methodologies or models such as the waterfall model. 

On page 680 the author says that, "The output of the level above is the input of the level below." This resonates the core of the waterfall approach to software development. The fact that a the output of a certain phase is used as the input to the next one. Phases such as domain problem characterization in the HCDP might be linked to the requirements gathering phase in the waterfall model. For example the characterization of the business problem that the software attempts to solve goes hand-in-hand with the gathering of requirements.

The involvement and the acknowledgement of human interaction in the whole process can also be related to software development. The reason for that is because the goal of both processes is to provide humans with an tool or technology that will enhance a our ability to make decisions and perform tasks.


The difference between Wilkinson and Polaris is the fact that Polaris uses a multi-dimensional relational database. The use of SQL can be seen as an advantage because SQL is a universal platform and many people are familiar with it.

Just a thought...

Does industry make use of tools such as Polaris or is it just an academic tool?

If so then: Would it not be a good idea to add more enterprise and industry features to it...In other words, Polaris would analyzes the database and visualize certain important specified and parameters that might be a problem. In other words a more “intelligent” tool.
