Design process

Different organizations have adapted their own style of innovating products.
Key Milestones in design process are :
- Know Your Audience
- Analyze User Tasks
- Build Prototypes
- Observe Users
- Guidelines for Conducting User Observations
- Making Design Decisions
When making design decisions regarding features in your application, it’s important to weigh the costs, not all of which are financial, against the potential benefits. Every time you add a feature to your application, the following things can happen:
• Your application gets larger.
• Your application gets slower.
• Your application’s human interface becomes more complex.
• You spend time developing new features rather than refining existing features.
• Your application’s documentation and help become more extensive.
• You run the risk of introducing changes that could adversely affect existing features.
• You increase the time required to validate the behavior of your application.
Choosing appropriate features and devoting the needed resources to implement them correctly can save you time and effort later. Choosing poor feature sets or failing to assign appropriate design, engineering, testing, and documentation resources often incurs heavier costs later when critical bugs appear or users can’t figure out how to use your product.
The following sections present several additional factors to take into consideration before adding features to your product.
