key element in building a high trust culture  
….

[provides] an organization level opportunity to reflect 
….

also invite value chain partners from other parts of IT and from the rest of the business and some senior management
….

opportunity to celebrate success
….

 when we have poor performance data to show people will discuss it openly
….

culture of personal safety where people can courageously speak up without fear of loss of face
….
[is this a prerequisite for or effect of ops review? a little bit of both?]
