FOCUS ON THE RIGHT THINGSYou want to build the whole world, but you only have limited time…

The Right Things

• Features that can make your solution unique• Features that required to make a smooth

presentation• Standard and user friendly interface• Focus on the “WOW” factor• Focus on the business value• Feature that can be complete in time

The Wrong Things

• Common required features but not unique– Login / Logout function– Registration function– Menu function (Copy, Cut, Paste, Save, Print, Help…)– Features implemented by competitor– Features implemented by other and freely available

• Unique features but not required– 3D bombing interface– Performance tuning

Example – Collaboration Tool

• More focus on– Simple UI design for simplicity– Direct language translation– Drag & drop image sharing

• Less focus on– Authentication function– Recording function

• Don’t focus on– Highly animated interface

have limited time.

Don’t waste it.

Stay Focus

• Write down the list of features you want to complete in time.

• Review with your team member whatever it is good enough to implement it.
