Grid is an oldie but a goodie
Although Blake's and Mouton's Grid was developed in the 1960's I think it captured the very essence of
how to assess managers.
Most organisations assess managers against getting the TASK done against time (the HOW) and of course this is what generates the value for the organisation. With modern well educated intelligent staff, however, managers need to also be concerned for how they engage the staff /PEOPLE (the HOW). Our Organisation's Performance Management System assesses against 1. Task and 2. Behaviours=concern for People, and thus the Grid would be perfect to use in assessing how managers are fairing in achieving a 'balance' between these two fundamental issues.
