See this quote by Field Marshal Sir Bill Slim.
In the British Army there are no good units and no bad units – only good and bad officers and NCOs. They make or break the unit.
~ Field Marshal Sir Bill Slim, 1949 (in the foreword to the first edition of the British Army Review, then called the British Army Journal)
I would argue that the same can be said of any organization, department, squad, etc.
There are no good organizations and no bad departments, squads, etc. There are only good or bad leaders. They – the leaders – make or break the organization, the department, the squad, etc.
Pick leaders well.
Train leaders well.
Mentor leaders well.
Leadership, if done right, can be a force for good in the world.
