🔍 Understanding the Time Study Sheet

#### Key Information:
- Operation: Collar run stitch (a sewing operation on a collar)
- Machine: SNLS
- Fabric: Poplin
- Style: Full Sleeve Shirt
- Operation Element Breakdown:
- Pick up & stitch 1st line
- Stitch 2nd line
- Stitch 3rd line
- Check and dispose
- Waiting (idle time)

Each row represents one operation cycle, with recorded times in tenths of seconds (T) and actual seconds (R).

We are given 5 cycles of observations, and we need to:
1. Calculate normal time per element.
2. Possibly calculate standard time if allowed time or performance rating is provided.
3. Identify foreign elements (like waiting), which may be removed from standard time calculation.

But since no performance rating or allowance is provided, we’ll focus on computing the average observed time for each element and then the normal time assuming 100% performance unless otherwise stated.

📊 Step-by-Step Analysis

Let’s first compute the average observed time (in tenths of seconds) for each element:

| Operation Cycle | Pick up & stitch 1st line | Stitch 2nd line | Stitch 3rd line | Check and dispose | Waiting |
|------------------|----------------------------|------------------|------------------|--------------------|---------|
| 1 | 5 | 4 | 12 | 9 | 6 |
| 2 | 4 | 3 | 41 | 8 | 0 |
| 3 | 6 | 5 | 60 | 11 | 5 |
| 4 | 7 | 4 | 46 | 10 | 0 |
| 5 | 7 | 3 | 105 | 3 | 0 |

Now, calculate average time (T) for each element:

#### ✔ Average Time Calculation:

- Pick up & stitch 1st line:
(5 + 4 + 6 + 7 + 7) / 5 = 5.8 tenths of seconds

- Stitch 2nd line:
(4 + 3 + 5 + 4 + 3) / 5 = 3.8 tenths of seconds

- Stitch 3rd line:
(12 + 41 + 60 + 46 + 105) / 5 = 50.8 tenths of seconds

- Check and dispose:
(9 + 8 + 11 + 10 + 3) / 5 = 8.2 tenths of seconds

- Waiting:
(6 + 0 + 5 + 0 + 0) / 5 = 2.2 tenths of seconds

⚠️ Foreign Elements

In time study, foreign elements are those that do not contribute to the actual work (e.g., waiting, idle time). In this case, "Waiting" is listed as a foreign element.

So, we should exclude waiting time when calculating normal time.

> ✔ Therefore, waiting time is not included in the standard time.

---

🧮 Total Normal Time (excluding foreign elements)

Sum of average times for productive elements:

- Pick up & stitch 1st line: 5.8
- Stitch 2nd line: 3.8
- Stitch 3rd line: 50.8
- Check and dispose: 8.2

✔ Total Normal Time = 5.8 + 3.8 + 50.8 + 8.2 = 68.6 tenths of seconds

Convert to seconds:
68.6 ÷ 10 = 6.86 seconds

---

💡 Final Answer

#### ✔ Normal Time for Operation (Collar Run Stitch):
> 6.86 seconds

This is the normal time based on observed data, assuming 100% performance rating and no allowances.

---

🛠️ Additional Notes (if needed):

If the company wants to calculate Standard Time, they would apply an allowance factor (e.g., 10–15% for fatigue, personal needs, delays).

Example:
If 10% allowance is applied:

> Standard Time = Normal Time × (1 + Allowance)
> = 6.86 × 1.10 = 7.55 seconds

But since no allowance is mentioned, we stop at normal time.

---

✔ Summary

| Element | Average Time (tenths of sec) | Time (seconds) |
|----------------------------|------------------------------|----------------|
| Pick up & stitch 1st line | 5.8 | 0.58 |
| Stitch 2nd line | 3.8 | 0.38 |
| Stitch 3rd line | 50.8 | 5.08 |
| Check and dispose | 8.2 | 0.82 |
| Total (Normal Time) | 68.6 | 6.86 s |
| Waiting (Foreign) | 2.2 | 0.22 s (excluded) |
