Bar chart
How accurate is one key informant, by question topic
How closely one key informant's answer matched an independent second source, by what the question was about, from Homburg and colleagues' 2012 meta-analysis of 127 studies. Hard performance figures agreed at .764, internal process questions at only .502, against .612 overall. Use it to decide which questions need a second informant from another role.
