WebApp Design Goals

WebApp Design Goals

• Introduction :
• Jean Kaiser suggests a set of design goals that are applicable to virtually every WebApp regardless of application domain, size, or complexity.
• The following are the set of design goals to apply webApp
• Simplicity
• Consistency
• Identity
• Robustness
• Navigability
• Visual Appeal 
• Compatibility

• Simplicity 
• Content should be informative but to the point and should use a delivery mode (e.g., text, graphics, video, audio) that is appropriate to the information that is being delivered.
• Architecture should achieve WebApp objectives in the simplest possible manner.
• Navigation should be straightforward and navigation mechanisms should be naturally obvious to the end user.
• Functions should be easy to use and easier to understand.
• Consistency
• This design goal applies to virtually every element of the design model.
• Content should be constructed consistently
• e.g., text formatting and font styles should be the same across all text documents;
• Graphic art should have a consistent look, color scheme, and style)
• Identity
• Establish an “identity” that is appropriate for the business purpose.
• Robustness (Strength)
• The user expects robust content and functions that are relevant to the user’s needs.
• Navigability
• Navigation should be simple and consistent.
• It should also be designed in a manner that is predictable.
• The user should understand how to move about the WebApp without having to search for navigation links or instructions.
• Visual appeal
• The look and feel of content, interface layout, color coordination, the balance of text, graphics and other media, navigation mechanisms must appeal to end-users
• Compatibility
• WebApp will be used in a variety of environments (e.g., different hardware, Internet connection types, operating systems, browsers)
• It must be designed to be compatible with each.
