Externally driven reforms (i.e., Sarbanes-Oxley, Dodd-Frank, etc.) have proven to be quite ineffective when it comes to improving boards of directors' oversight of firms. It has been noted that the "one size fits all" approach has not worked. "Improving [board] oversight involves something more than imposing a structure, or requiring attendance at board meetings, or installing independent, supposedly impartial people." Do you agree with this statement that external rules and regulations have been ineffective?
