Prototyping Overview

Prototyping is a way of managing and setting the expectations about the final system. It is the process of building a model of the proposed system. Mostly its the part of the analysis phase but its also a way of telling and asking the user that what the final system should be. For generating ideas IDEO was a new thing for me. It really helped me alot.

In website layout design a CRAP is a new thing for me. CRAP is

CRAP

•Contrast

•Repetition

•Alignment

•Proximity

Below is the image of a site developed in OpenLaszlo a new framework for the web pages. This site is a Demo site put on the webpage www.openlaszlo.org. A very bad idea is implemented here having the menus right corner negating our F-pattern for the Eye-tracking. CRAP could only help to set a new layout

Among the advantages of the prototypes are the following Some Advantages of Prototyping: cited at http://www.umsl.edu/~sauterv/analysis/prototyping/proto.html

• Reduces development time.
  

• Reduces development costs.
  

• Requires user involvement.
  

• Developers receive quantifiable user feedback.
  

• Facilitates system implementation since users know what to expect.
  

• Results in higher user satisfaction.
  

• Exposes developers to potential future system enhancements.
  

In my previous writing I made a use case for the Go Game. Below is its prototype. Its not fully functional as one can see that white has just commit a suicide and there is no indication of it visually though an exception was thrown.
