## Conducting an interview
|
|
### Choosing participants

|
|
- get pople who are representive of users
|
|
- users of existing similar system
|
|
- non-users -> why people arent using a system
|

|
|
|
|
#### Recruiting
|
|
- Craiglist (in US)
|
|
- your network
|
|
- cheaper for less speciales users
|
|
- if you can convince people you are imporving the world they might volunteer
|
|
- if they think is is for profict they will expect to be paid
|
|
- if you cant pay -> you cant use a token of appreciation
|
|
|
|
### Process
|
|
- introduce yourself explaint he purpose
|
|
- the interview is about them, not you?
|
|
- begin with open, unbiased questions-> then follow up
|
|
- ask the questions, and let them answer
|
|
- have breaks and give them time
|
|
- have a clear separation between the general introduction, the actual interview, and post inteview discussions
|
|
|
|
### Questions to avoid:
|
|
- leading questions
|
|
- what would they do / like / want in a hypothetical scenario
|
|
- how often they do things
|
|
- how much they like things on an absolute scale
|
|
- avoid binary questions
|
|
|
|
## Pros/cons

|
|
+ oppportunity for follow up
|
|
- time consuming and resource intensive
|
|
- dependent of commication skills of analyst
|
|
- location/schedule can make this impractical
