This blog mentions that one KPI that can be tracked in custom fields is Customer Satisfaction Score. I'm interesting in learning how others are doing this.
We've been looking at ways to send our internal clients a survey after a specific task is complete plus get their feedback into Workfront so we can easily report on it.
We want to send the survey after a specific task because we have some projects where the deliverable is complete, but there are additional tasks that happen weeks or months later so the project does not end as soon as the deliverable is first completed.
