Q.Ashita and Lakshita are employees working in Dazzling enterprises dealing in costume jewellery. The firm secured an urgent order for 1,000 bracelets that were to be delivered within 4 days. They were assigned the responsibility of producing 500 bracelets each at a cost of Rs 100 per bracelet. Ashita was able to produce the required number within the stipulated time at the cost of Rs 55,000 whereas, Lakshita was able to produce only 450 units at a cost of Rs 90 per unit. State whether Ashita and Lakshita are efficient and effective. Give reasons to justify your answer.

Let’s break this down by the two management concepts: effectiveness means completing the task — achieving the goal — and efficiency means doing so at the lowest possible cost (minimising resource use).

• Ashita produced all 500 bracelets within the 4-day deadline. That makes her effective. Her actual cost was Rs 55,000, whereas the standard cost for 500 units at Rs 100 each would be Rs 50,000. Since she spent Rs 5,000 more than planned, she is not efficient. …

In management, two words that often travel together but mean very different things are efficiency and effectiveness. Think of efficiency as the means — how well you use your resources (time, money, materials) to get the job done. Effectiveness, on the other hand, is the end — whether you actually achieved the goal you set out to accomplish. A manager or employee can be good at one but poor at the other, and the best performers excel at both.

Let’s apply this to the case of Ashita and Lakshita at Dazzling Enterprises. The firm had an urgent order for 1,000 bracelets to be delivered in 4 days. Each employee was assigned 500 bracelets, with a target cost of Rs 100 per bracelet. That means the expected total cost for each was 500 × Rs 100 = Rs 50,000. The goal was clear: produce 500 units within 4 days, at or below Rs 50,000.

Now look at Ashita. She produced exactly 500 bracelets — the full target — within the 4-day deadline. That makes her effective: she achieved the desired result. Her actual cost was Rs 55,000, which is Rs 5,000 more than the planned Rs 50,000. But here’s the key: the cost per bracelet she incurred was Rs 55,000 ÷ 500 = Rs 110. That is higher than the target of Rs 100 per bracelet. So was she efficient? Efficiency means minimising resource usage — in this case, cost. Since she spent more than planned per unit, she was not efficient. She got the job done, but at a higher cost.

Method: Efficiency vs. Effectiveness Analysis

Method Name: The 2×2 Performance Matrix (Efficiency × Effectiveness)

Steps to Solve

Step 1: Define the two concepts clearly

• Effectiveness = Doing the right things (achieving the goal/target)
• Efficiency = Doing things right (achieving the goal at minimum cost)

Step 2: Identify the given targets

Step 3: Analyse Ashita’s performance

• Effectiveness check:

  Produced 500 units within 4 days → Target achieved ✓

  → Ashita is effective.

• Efficiency check:

  Actual cost = ₹55,000

  Standard cost = ₹50,000

  Cost overrun = ₹5,000 (more than standard)

  → Ashita is NOT efficient (she spent more than the standard cost).

Step 4: Analyse Lakshita’s performance

• Effectiveness check:

  Produced only 450 units (target was 500) → Target NOT achieved ✗

  → Lakshita is NOT effective.

• Efficiency check:

  Actual cost per unit = ₹90 (less than ₹100 standard)

  Total actual cost = 450 × ₹90 = ₹40,500

  Standard cost for 450 units = 450 × ₹100 = ₹45,000

  → Saved ₹4,500 compared to standard …

Here are the most common mistakes students make when analyzing this case study on Efficiency and Effectiveness, along with how to avoid each.

Mistake 1: Confusing the Definitions of Efficiency and Effectiveness

The Error:

Students often swap the two terms. They might say Ashita is effective because she saved money, or that Lakshita is efficient because she worked cheaply.

The Correct Understanding:

• Effectiveness is about doing the right things — achieving the goal (target output and deadline).
• Efficiency is about doing things right — achieving the goal with the minimum cost or resources.

How to Avoid:

Always ask two separate questions:

1. Did they achieve the target? (Effectiveness)
2. Did they do it at or below the planned cost? (Efficiency)

Mistake 2: Miscalculating the "Planned Cost" for Efficiency

The Error:

Students compare Ashita’s actual cost (Rs 55,000) directly to Lakshita’s actual cost (Rs 90/unit) without first calculating the standard or planned cost for each person.

The Correct Calculation:

The firm planned a cost of Rs 100 per bracelet. For 500 units, the planned cost for each was:

500 units × Rs 100 = Rs 50,000

How to Avoid:

Always compute the budgeted/standard cost first. Then compare:

• Ashita: Actual cost = Rs 55,000. Planned cost = Rs 50,000. Since 55,000 > 50,000, she is not efficient (she overspent).
• Lakshita: Actual cost = Rs 90 per unit. Planned cost = Rs 100 per unit. Since 90 < 100, she is efficient (she saved money per unit).

Mistake 3: Ignoring the "Quantity" Dimension in Effectiveness

The Error:

Students see that Lakshita produced at a lower cost and assume she was effective. They forget that effectiveness requires meeting the full target quantity.

The Correct Analysis:

• Ashita: Produced 500 units (target met) within 4 days (deadline met). She is effective.
• Lakshita: Produced only 450 units (target of 500 not met). She is not effective, regardless of cost savings.

How to Avoid:

Check the output quantity and deadline before checking cost. If the target is missed, the person is ineffective by definition.

Mistake 4: Giving a "Partial" or "Mixed" Answer Without Clear Reasoning

The Error:

Students write "Ashita is effective but not efficient" without explaining why using the numbers from the case.

The Correct Answer Format (for exams):

Ashita:

• Effective: Yes. Reason: She produced 500 units (target) within 4 days (deadline). …
