Car number five, the engine falls out

Fig 1 You want add person to your network

 

Fig 2 You do not know this person

 

Fig 3 After you clicked ‘Send Invitation’ all your typing is lost

 

My conclusions:
- human testing is irreplaceable
- don’t put an option in ‘can not be used’ context – remove option instead (radio ‘I don’t know …’)
- never assume customer will use default message which has no value when lost
- give customers interface to suggest without counting typed characters and with ability to attach documents (even with 1:100 ratio of useful:useless you will improve product into right direction).

LinkedIn added ‘Send us your Feedback’ page but it still does not allow attachments.
