Q: In a factory the production route was shortened but workers did not receive the new route in written instructions. Which coordination is weak?

Route clerk and instruction card clerk The governing concept is functional coordination in Taylor's specialised foremanship system. The route clerk determines the production path or sequence through which work should move, whereas the instruction-card clerk records the required method and communicates it through written instructions. If the route has been shortened but the revised route is absent from the instruction card, these two planning-related functions are not coordinated. Hence option A is correct. The speed boss deals with the pace of work, the repair boss with machine maintenance, the inspector with quality and the disciplinarian with conduct; none explains the missing written route instruction.

Q: A worker received correct written instruction but material and jig were not available when work started. Which production specialist will be responsible?

Gang boss Providing resources to start work is linked with gang boss. Exam tip: separate instruction and setup.

Q: If defects are seen in finished goods but the defect report does not show time and cost impact which record is weak?

Time and cost clerk record Time and cost impact of defects is known from time and cost records. Exam tip: check both quality and cost control.

Q: A task has 840 minutes available and time per unit is 14 minutes. What will be the standard output?

60 units Standard output is found by dividing the total available time by the standard time per unit: \(840 \div 14 = 60\). Therefore, the standard output is 60 units. If the output were 55 units, the time per unit would be about \(15.27\) minutes, not the given 14 minutes. Exam tip: In time-study numericals, use output = total available time ÷ time per unit.

Q: Standard is 108 units. A worker produces 104 units and the low rate is ₹11. What will be the wage?

₹1144 The worker produces 104 units, which is below the standard of 108 units. Under Taylor’s differential wage system, the low rate applies when output is below the standard. Therefore, the wage is \(104 \times 11 = ₹1144\). An amount such as ₹1122 would result from 102 units, not 104 units. Exam tip: first compare output with the standard, then multiply by the applicable rate.

Q: A worker produces 132 units. Standard is 125 and high rate is ₹6. 7 units are rejected. If payment is on accepted output what will be the wage?

₹750 Accepted output = 132 - 7 = 125 units. Since this equals the standard output of 125 units, the worker earns the high rate of ₹6 per unit. Wage = 125 × ₹6 = ₹750. ₹792 is incorrect because it applies the high rate to all 132 units, including the 7 rejected units. Exam tip: When payment is based on accepted output, subtract rejected units before comparing output with the standard.

Q: If standard method is applied but suppliers provide material of different density which conclusion is correct?

Standardisation is incomplete on input side Input quality should also be standard along with the same method. Exam tip: connect material variability with standardisation.

Q: If 28 product variants were reduced to 9 but the market complained that a high demand variant was removed where is the mistake?

Balanced simplification was not done with demand analysis Simplification reduces unnecessary varieties not essential demand. Exam tip: check demand before variety reduction.

Q: If product size is standard but too many packaging colours are increasing storage bins which technique is still needed?

Simplification Size is standardisation but reducing excessive colour variety is simplification. Exam tip: read standards and variety separately.

Q: If product variants are few but every packet has different weight which standard is weak?

weight standard / Weight standard Uniformity of weight is linked with standardisation. Exam tip: connect measurement variation with standardisation.

Answer and explanation

Correct answer: A. Route clerk and instruction card clerk

The governing concept is functional coordination in Taylor's specialised foremanship system. The route clerk determines the production path or sequence through which work should move, whereas the instruction-card clerk records the required method and communicates it through written instructions. If the route has been shortened but the revised route is absent from the instruction card, these two planning-related functions are not coordinated. Hence option A is correct. The speed boss deals with the pace of work, the repair boss with machine maintenance, the inspector with quality and the disciplinarian with conduct; none explains the missing written route instruction.
