Creating a QC protocol

When creating a new document for collecting quality checking records

  • use Pitt credentials on office365's http://excel.office.com/ (google drive blocked by UPMC, UPMC onedrive cannot share links externally)
  • provide a score (eg. 0-3), see Scoring below for example rubric
  • allow for optional annotations
  • if possible, collect screenshots, see “picture-in-cell” for pasting screenshots on specified row

Scoring

Here's an example rubric

score desc
0 bad data, cannot recover
1 processed failed, try rerunning
2 looks *okay* but if visit is outlier, check here again
3 process worked as expected
