In a management by objectives program $($MBO$),$ why must managers be careful not to conclude automatically that employees have produced at an acceptable level simply because they have reached their objectives?

Select one:

a$.$

The objectives may have been set too low in the first place, and managers may have failed to recognize it at the time.

b$.$

The MBO framework is naturally flawed and requires managers to use subjective criteria to evaluate performance.

c$.$

The employees may have reached their objectives by means that the organization had not considered.

d$.$

The MBO approach is merely on goal attainment and not on the level of effort expended.

e$.$

The objectives set for employees may not be aligned with the overall organizational objectives.
