"Rather than implement yet another management technique, I would suggest that the more diversity there is in your team / organisation, the lower the overlap in features that each team member selects; i.e. each team member still picks up on about a third of an object's features, but members with different cultural etc backgrounds would be more likely to pick a different range of features. Given enough diversity and enough team members, the TEAM would select all features.  The hard work is convincing management to let you build your team based on diversity, and working out a rough enough combination of numbers and diversity (without creating a United Nations sized team). hth" - martin english
