Concept:
In management, two important performance concepts are
Effectiveness and
Efficiency. Although they are related, they have different meanings.
- Effectiveness refers to achieving the desired goals or objectives. It focuses on doing the right tasks.
- Efficiency refers to achieving goals with minimum resources, time, or cost. It focuses on doing tasks in the best possible way.
In simple terms:
\[
Effectiveness = Doing the right things
\]
\[
Efficiency = Doing things right
\]
An ideal manager should aim to be both effective and efficient. However, in some situations a manager may achieve the target but waste resources, or use resources efficiently but fail to achieve the target.
Step 1: Analyze the situation described in the question.
- Target set by the company: 1,000 units
- Actual production achieved: 1,000 units
Since the manager achieved the target, the goal has been accomplished.
Step 2: Evaluate efficiency.
The problem states that the target was achieved at
double the cost due to inefficiencies. This means excessive resources were used.
Therefore, the manager is
not efficient.
Step 3: Determine effectiveness.
Since the objective (producing 1,000 units) was achieved, the manager is
effective.
Step 4: Final evaluation.
\[
\text{Goal achieved} \Rightarrow \text{Effective}
\]
\[
\text{Resources wasted} \Rightarrow \text{Not Efficient}
\]
Thus, the manager is:
\[
\boxed{\text{Effective but not Efficient}}
\]
