The Managerial Grid Model (1964) is a behavioral leadership model developed by Robert Blake and Jane Mouton. This model identifies five different leadership styles based on the concern for people and the concern for production.The question is, how much attention do they pay to one or the other? This is a model defined by Blake and Mouton in the early 1960s. The Blake and Mouton Managerial Grid uses two axis:

1. "Concern for people" is plotted using the vertical axis.
2. "Concern for task" is along the horizontal axis.

As shown in the figure, the model is represented as a grid, with concern for production as the X-axis and concern for people as the Y-axis; each axis ranges from 1 (Low) to 9 (High).The notion that just two dimensions can describe a managerial behavior has the attraction of simplicity. These two dimensions can be drawn as a graph or grid:

The five resulting leadership styles are as follows:

Impoverished management
Minimum effort to get the work done. A basically lazy approach that avoids as much work as possible.

Authority-compliance
Strong focus on task, but with little concern for people. Focus on efficiency, including the elimination of people wherever possible.

Country Club management
Care and concern for the people, with a comfortable and friendly environment and collegial style. But a low focus on task may give questionable results.

Middle of the road management
A weak balance of focus on both people and the work. Doing enough to get things done, but not pushing the boundaries of what may be possible.

Team management
Firing on all cylinders: people are committed to task and leader is committed to people (as well as task).

Discussion
This is a well-known grid that uses the Task vs. Person preference that appears in many other studies, such as the Michigan Leadership Studies and the Ohio State Leadership Studies. Many other task-people models and variants have appeared since then. They are both clearly important dimensions, but as other models point out, they are not all there is to leadership and management. The Managerial Grid was the original name. It later changed to the Leadership Grid.
