What get measured get done. What not get measured get undone.
What boss frowns at get done while at the expense of all other job task. The peers – upstream and downstream, are frustrated.
Expedition makes the critical task done at the expense of all other job task. It also occupies the precious time resource of the senior.
The criticism of Senior against junior would create more disgruntle from the junior against senior. Default to perform the necessary task would itself embarrass the wrongdoer when he is in front of his peers. Losing face will drive the wrongdoer to regain respect from his peers in the coming future.
Management by harmonization is not a devil. Cover-up may not be resulted provided the referee (the manager) can judge disinterestedly.
