in User Centered Design

User Goals, Tasks & Context of Use :

While tasks are means with which, an user achieves his goals, the interface design must be primarily centered around on the user’s goals.

The basic need for an novice user would be ” learn-ability” or “ease of use”.
For an advanced user, “productivity” or “short cuts” would be his primary concern.

User friendly interfaces must recognize the context of use and offer different options for different users
Eg : Lets take a B2C e-commerce portal.

While tasks are means with which, an user achieves his goals, the interface design must be primarily centered around on the user’s goals.

The basic need for an novice user would be ” learn-ability” or “ease of use”.
For an advanced user, “productivity” or “short-cuts” would be his primary concern.

User friendly interfaces must recognize the context of use and offer different options for different users
Eg : Lets take a B2C e-commerce portal.

The shopping cart page must cater to the needs of the ‘first time shopper’ and also the ‘returning user’.

The goal of a ‘returning user’ would be to quickly close the transaction. The interface must also provide a “express check out” button to facilitate the same. The user will get bored and his time will be wasted, if he is again and again asked to key-in shipping address, billing address and choose his payment option.

The one of the goals of the ‘first time shopper’ would be … lets say …. “Safety of credit card information” The interface must display information guaranteeing safety & security.

User centered interfaces will make the users feel excited, confident, intelligent, successful and productive. It will not make them feel dumb & bored. It will prevent them from making mistakes.
