Self reported data gives you the user’s perception of a system. As a product manager it is key to understand how a user think about the tasks they perform. This will highlight how users feel about a system and will complement time taken and success measured on task flows.
Using a ‘Likert’ or ‘Semantic Differential Scale’ over a range of questions will provide you information on how agreeable or attributes that users relate to in your product
System Usability Scale
One of the most widely used tools to measure system usability. This was developed with five positively and five negatively worded questions. A five point scale is used for each. The SUS has been freely available for research and can be used.
Questionnaire for User Interface Satisfaction
QUIS is another standard format which covers areas like overall satisfaction, accessibility, language and system capabilities.
Usefulness, Satisfaction and Ease of use Questionnaire
As the title suggests, this provides a set of questions which will give you user’s perception on the above.
Net Promoter Score
NPS is intended to measure customer loyalty, it basically finds out how likely is it that a user recommends your product. The output is in groups of ‘Detractors’, ‘Passives’ and ‘Promoters’.
Other online tools
Tools like WAMMI, ASCI and OpinionLab provide similar feedback from users
