# QUESTION 4 - Chegg India Style Solution
## Data Table
| Unit Number | Time (hours) |
|-------------|--------------|
| 1 | 970 |
| 2 | 640 |
| 3 | 420 |
| 4 | 380 |
| 5 | 320 |
| 6 | 250 |

| 12 | 170 |
| 13 | 150 |
| 14 | 140 |
| 15 | 135 |
| 16 | 120 |
---
## a. Estimate the Learning Rate
Learning rate is calculated using the cumulative average time method:
\[
\text{Learning Rate (LR)} = \frac{\text{Time to produce 2n units}}{\text{Time to produce n units}}
\]
Let's use units 1 and 2 as an example:
\[
\text{Time for 1st unit} = 970 \text{ hours}
\]
\[
\text{Time for 2 units (average)} = \frac{970+640}{2} = 805
\]
But for standard learning rate, use the formula:
\[
\text{LR} = \frac{\text{Time for 2nd unit}}{\text{Time for 1st unit}}
= \frac{640}{970} = 0.6598 \approx 66\%
\]
So, **estimated learning rate is 66%**.
---
## b. Time to Produce the Next 240 Units
For total time, use the **cumulative average time formula**:
\[
Y = aX^b
\]
where:
- \( Y \) = Time for the Xth unit,
- \( a \) = Time for the first unit = 970 hours,
- \( b = \frac{\log(\text{Learning Rate})}{\log 2} \).
Calculate \( b \):
\[
b = \frac{\log(0.66)}{\log 2} = \frac{-0.1805}{0.3010} \approx -0.6
\]
Find time for 17th to 256th (next 240 units after 16):
\[
\text{Total time for first 16 units} = \sum_{i=1}^{16} t_i = 970+640+420+380+320+250+220+207+200+190+190+170+150+140+135+120 = 4702 \text{ hours}
\]
For the next 240 units (from unit 17 to 256):
\[
\text{Cumulative time for 256 units} = \sum_{i=1}^{256} a \cdot i^b
\]
\[
\text{Cumulative time for 16 units} = \sum_{i=1}^{16} a \cdot i^b
\]
\[
\text{Time for next 240 units} = \text{Cumulative time for 256 units} - \text{Cumulative time for 16 units}
\]
But for estimation, use average time for 256th unit:
\[
Y_{256} = 970 \cdot (256)^{-0.6} = 970 \cdot (256^{0.6})^{-1}
\]
\[
256^{0.6} = e^{0.6 \cdot \ln(256)} = e^{0.6 \cdot 5.5452} = e^{3.327} \approx 27.88
\]
\[
Y_{256} = 970 / 27.88 \approx 34.8 \text{ hours}
\]
Average time per unit for 17-256:
Take average of unit 17 and unit 256, then multiply by 240.
\[
\text{Time for 17th unit} = 970 \cdot 17^{-0.6} = 970 / (17^{0.6}) \approx 970 / 5.44 \approx 178.31 \text{ hours}
\]
Average for 17th and 256th unit:
\[
\text{Average} = \frac{178.31 + 34.8}{2} = 106.56
\]
Total time for 240 units ≈ \( 240 \times 106.56 = 25,574.4 \) hours
---
## c. Time for 1000th Unit
\[
Y_{1000} = 970 \cdot 1000^{-0.6}
\]
\[
1000^{-0.6} = e^{-0.6 \cdot \ln(1000)} = e^{-0.6 \cdot 6.908} = e^{-4.1448} \approx 0.0159
\]
\[
Y_{1000} = 970 \times 0.0159 \approx 15.43 \text{ hours}
\]
---
## d. Time for 3000th Unit
\[
Y_{3000} = 970 \cdot 3000^{-0.6}
\]
\[
3000^{-0.6} = e^{-0.6 \cdot \ln(3000)} = e^{-0.6 \cdot 8.006} = e^{-4.8036} \approx 0.0082
\]
\[
Y_{3000} = 970 \times 0.0082 \approx 7.97 \text{ hours}
\]
---
## e. Graph the Learning Curve (First 20 Units)
*You can plot the following on Excel or any graph tool:*
| Unit | Time (hours) |
|------|--------------|
| 1 | 970 |
| 2 | 640 |
| 3 | 420 |
| ... | ... |
| 16 | 120 |
| 17 | 114 |
| 18 | 109 |
| 19 | 104 |
| 20 | 100 |
*Plot Unit Number (x-axis) vs Time (y-axis). Curve should show a decreasing trend.*
---
## f. Add 75% and 95% Learning Rate Curves
**For 75% LR:**
\[
b_{75\%} = \frac{\log(0.75)}{\log 2} = \frac{-0.1249}{0.3010} = -0.415
\]
**For 95% LR:**
\[
b_{95\%} = \frac{\log(0.95)}{\log 2} = \frac{-0.0223}{0.3010} = -0.074
\]
Plot these curves using \( Y = 970 \cdot X^b \) for \( X = 1 \) to \( 20 \).
**Comment:**
- 66% LR curve drops fastest (steeper slope, fastest learning).
- 75% LR curve drops slower.
- 95% LR curve drops very slowly (least learning, almost flat).
---
## g. Managerial Decision on Learning Rate (65%, 75%, 90%, 110%)
- **65% & 75%:** Faster learning, costs drop quickly, but may be unrealistic (more errors, quality issues).
- **90%:** Moderate, achievable in industry.
- **110%:** Negative learning (getting worse), not acceptable.
**Best:** As a manager, target a realistic but challenging learning rate (75%-85%). Too aggressive may harm quality; too slow (90%+) increases cost.
---
## Final Summary
- **Estimated learning rate:** 66% (fast learning).
- **Next 240 units:** ~25,574 hours.
- **1000th unit:** ~15.43 hours.
- **3000th unit:** ~7.97 hours.
- **Learning curve:** Steep decline initially, flattens later.
- **Different rates:** Lower learning rate = faster improvement.
- **Manager's choice:** Balance between speed and quality, typically aim for 75%-85% learning rate.
