Solution:

	Average Time per month (in days)
Particulars	1	2	3	4
Throughput Time	7.30	8.10	8.80	9.60
Delivery Cycle	16.30	19.60	20.80	23.60
Manufacturing Cycle Efficiency	0.29	0.25	0.22	0.19

Explanation of Solution

Throughput time comprises of two main categories of elements i.e. Value added and Non Value added elements.

Value added elements refer to the time taken for those activities that add quality and value to the overall production process concerning manufacture of goods. Example − Process Time.

Process time is the time spent on actually producing the product. It refers to the time taken to convert the goods from raw materials to interim or final finished products

Non Value added elements refer to the time taken for those activities that do not add quality and value to the overall production process concerning manufacture of goods and that need to be eliminated to the greatest extent possible. Example - Inspection Time, Move Time and Queue time

Inspection time is the amount of time spent assuring that the product is defect free to the best possible extent

Move time is the time required to transfer raw materials or interim or final finished products from one location to another, such as factory to job workers’ location.

Queue time is the amount of time that is spent waiting for the actually production activities to commence since other products are being produced or worked upon.

Given:

	Average Time per month (in days)
Particulars	1.0	2.0	3.0	4.0
Move time per unit	0.3	0.4	0.4	0.5
Process Time per unit	2.1	2.0	1.9	1.8
Wait time per order	9.0	11.5	12.0	14.0
Queue Time per unit	4.3	5.0	5.8	6.7
Inspection Time per unit	0.6	0.7	0.7	0.6

Formulas Used:

Total Throughput Time = Time Taken by value added activities + Time Taken by Non value added activities (Except Wait Time)

Delivery Cycle = Non Value Added activities + Total Throughput Time

Manufacturing cycle efficiency = Time Taken by value added activities / Total Throughput Time.

Time Taken by value added activities = Time taken for Process Time

Time Taken by Non value added activities = Time taken for Move Time + Queue Time + Inspection Time

Calculations:

	Average Time per month (in days)
Particulars	1.0	2.0	3.0	4.0

Move time per unit	0.3	0.4	0.4	0.5
Queue Time per unit	4.3	5.0	5.8	6.7

Evaluation of Manufacturing Cycle efficiency and its’ components

The time taken from the start of the sale process, i.e. the receipt of a confirmed sales order, to the completion of the transfer of goods or services, i.e. dispatch of goods is known as the Delivery Cycle.

It consists of throughput time, Value added time and non-value added time.

To depict delivery cycle in the formula form, the following formula maybe used:

Delivery Cycle = Value added Elements of Throughput Time + Non Value Added Elements of Throughput Time.

Manufacturing Cycle Efficiency is an internal business performance parameter with respect to manufacturing processes and industries. It measures the total time taken by value added activities in relation to the throughput time.

Hence evaluation has to be done of the following parameters:

Throughput time
Delivery Cycle Time
Manufacturing Cycle Efficiency

To determine

Areas where company’s performance is improving.

Areas where company’s performance is deteriorating.

Expert Solution

Answer to Problem 19P

Solution:

Areas where company’s performance is improving are None
Areas where company’s performance is deteriorating are throughput time and delivery cycle time and manufacturing cycle efficiency.

Explanation of Solution

Throughput time comprises of two main categories of elements i.e. Value added and Non Value added elements.

Value added elements refer to the time taken for those activities that add quality and value to the overall production process concerning manufacture of goods. Example − Process Time.

Non Value added elements refer to the time taken for those activities that do not add quality and value to the overall production process concerning manufacture of goods and that need to be eliminated to the greatest extent possible. Example - Inspection Time, Move Time and Queue time

Following are the Throughput time for four months:

	Average Time per month (in days)
Particulars	1	2	3	4
Throughput Time	7.30	8.10	8.80	9.60

Since the total throughput time is increasing, it can be said the company’s performance is deteriorating.

The time taken from the start of the sale process, i.e. the receipt of a confirmed sales order, to the completion of the transfer of goods or services, i.e. dispatch of goods is known as the Delivery Cycle.

Following are the Delivery cycle times for four months:

	Average Time per month (in days)
Particulars	1	2	3	4
Delivery Cycle	16.30	19.60	20.80	23.60

Since the total delivery cycle time is increasing, it can be said the company’s performance is deteriorating.

Manufacturing cycle efficiency helps keep track of where time and cost is incurred in non-value added activities and performance efficiency measurement.

Manufacturing cycle efficiency is denoted by the following formula:
Manufacturing cycle efficiency = Time Taken by value added activities / Total Throughput Time.

Total Throughput Time = Time Taken by value added activities + Time Taken by Non value added activities

For example if the time Taken by value added activities is 25 minutes per unit and the Time Taken by non-value added activities is 35 minutes then manufacturing cycle efficiency would be 0.42.
Thus it can be interpreted as, the value added activities take up only 42 % of the total time taken to complete the manufacturing process and the rest is attributable to non-value added activities.

Following are the Manufacturing cycle efficiency for four months:

	Average Time per month (in days)
Particulars	1	2	3	4
Manufacturing Cycle Efficiency	0.29	0.25	0.22	0.19

Since the Manufacturing Cycle Efficiency is decreasing, the company’s performance is deteriorating.

Conclusion

Hence the performance measures where the company’s performance is increasing and decreasing are enumerated.

Expert Solution

Answer to Problem 19P

Solution:

	Average Time per month (in days)
Particulars	1	2	3	4
Throughput Time	7.30	8.10	8.80	9.60
Delivery Cycle	16.30	19.60	20.80	23.60
Manufacturing Cycle Efficiency	0.29	0.25	0.22	0.19

Explanation of Solution

Throughput time comprises of two main categories of elements i.e. Value added and Non Value added elements.

Value added elements refer to the time taken for those activities that add quality and value to the overall production process concerning manufacture of goods. Example − Process Time.

Process time is the time spent on actually producing the product. It refers to the time taken to convert the goods from raw materials to interim or final finished products

Non Value added elements refer to the time taken for those activities that do not add quality and value to the overall production process concerning manufacture of goods and that need to be eliminated to the greatest extent possible. Example - Inspection Time, Move Time and Queue time

Inspection time is the amount of time spent assuring that the product is defect free to the best possible extent

Move time is the time required to transfer raw materials or interim or final finished products from one location to another, such as factory to job workers’ location.

Queue time is the amount of time that is spent waiting for the actually production activities to commence since other products are being produced or worked upon.

Given:

	Average Time per month (in days)
Particulars	1.0	2.0	3.0	4.0
Move time per unit	0.3	0.4	0.4	0.5
Process Time per unit	2.1	2.0	1.9	1.8
Wait time per order	9.0	11.5	12.0	14.0
Queue Time per unit	4.3	5.0	5.8	6.7
Inspection Time per unit	0.6	0.7	0.7	0.6

Formulas Used:

Total Throughput Time = Time Taken by value added activities + Time Taken by Non value added activities (Except Wait Time)

Delivery Cycle = Non Value Added activities + Total Throughput Time

Manufacturing cycle efficiency = Time Taken by value added activities / Total Throughput Time.

Time Taken by value added activities = Time taken for Process Time

Time Taken by Non value added activities = Time taken for Move Time + Queue Time + Inspection Time

Calculations:

	Average Time per month (in days)
Particulars	1.0	2.0	3.0	4.0

Move time per unit	0.3	0.4	0.4	0.5
Queue Time per unit	4.3	5.0	5.8	6.7
Inspection Time per unit	0.6	0.7	0.7	0.6
Total Time For Non Value Added Activities (A)	5.2	6.1	6.9	7.8
Process Time per unit	2.1	2.0	1.9	1.8
Total Time For Non Value Added Activities (B)	2.1	2.0	1.9	1.8
Throughput Time (A+B) [C]	7.3	8.1	8.8	9.6
Wait time per order [D]	9.0	11.5	12.0	14.0
Delivery Cycle (C+D)	16.3	19.6	20.8	23.6
Manufacturing Cycle Efficiency	Time Taken by value added activities / Total Throughput Time.
Manufacturing Cycle Efficiency	0.29	0.25	0.22	0.19

Conclusion

Hence the throughput time, delivery cycle, and manufacturing cycle efficiency has been calculated for each months.

Evaluation of Manufacturing Cycle efficiency and its’ components

The time taken from the start of the sale process, i.e. the receipt of a confirmed sales order, to the completion of the transfer of goods or services, i.e. dispatch of goods is known as the Delivery Cycle.

It consists of throughput time, Value added time and non-value added time.

To depict delivery cycle in the formula form, the following formula maybe used:

Delivery Cycle = Value added Elements of Throughput Time + Non Value Added Elements of Throughput Time.

Manufacturing Cycle Efficiency is an internal business performance parameter with respect to manufacturing processes and industries. It measures the total time taken by value added activities in relation to the throughput time.

Hence evaluation has to be done of the following parameters:

Throughput time
Delivery Cycle Time
Manufacturing Cycle Efficiency

To determine

Areas where company’s performance is improving.

Areas where company’s performance is deteriorating.

Expert Solution

Answer to Problem 19P

Solution:

Areas where company’s performance is improving are None
Areas where company’s performance is deteriorating are throughput time and delivery cycle time and manufacturing cycle efficiency.

Explanation of Solution

Throughput time comprises of two main categories of elements i.e. Value added and Non Value added elements.

Value added elements refer to the time taken for those activities that add quality and value to the overall production process concerning manufacture of goods. Example − Process Time.

Non Value added elements refer to the time taken for those activities that do not add quality and value to the overall production process concerning manufacture of goods and that need to be eliminated to the greatest extent possible. Example - Inspection Time, Move Time and Queue time

Following are the Throughput time for four months:

	Average Time per month (in days)
Particulars	1	2	3	4
Throughput Time	7.30	8.10	8.80	9.60

Since the total throughput time is increasing, it can be said the company’s performance is deteriorating.

The time taken from the start of the sale process, i.e. the receipt of a confirmed sales order, to the completion of the transfer of goods or services, i.e. dispatch of goods is known as the Delivery Cycle.

Following are the Delivery cycle times for four months:

	Average Time per month (in days)
Particulars	1	2	3	4
Delivery Cycle	16.30	19.60	20.80	23.60

Since the total delivery cycle time is increasing, it can be said the company’s performance is deteriorating.

Manufacturing cycle efficiency helps keep track of where time and cost is incurred in non-value added activities and performance efficiency measurement.

Manufacturing cycle efficiency is denoted by the following formula:
Manufacturing cycle efficiency = Time Taken by value added activities / Total Throughput Time.

Total Throughput Time = Time Taken by value added activities + Time Taken by Non value added activities

For example if the time Taken by value added activities is 25 minutes per unit and the Time Taken by non-value added activities is 35 minutes then manufacturing cycle efficiency would be 0.42.
Thus it can be interpreted as, the value added activities take up only 42 % of the total time taken to complete the manufacturing process and the rest is attributable to non-value added activities.

Following are the Manufacturing cycle efficiency for four months:

	Average Time per month (in days)
Particulars	1	2	3	4
Manufacturing Cycle Efficiency	0.29	0.25	0.22	0.19

Since the Manufacturing Cycle Efficiency is decreasing, the company’s performance is deteriorating.

Conclusion

Hence the performance measures where the company’s performance is increasing and decreasing are enumerated.

Evaluation of Manufacturing Cycle efficiency and its’ components

The time taken from the start of the sale process, i.e. the receipt of a confirmed sales order, to the completion of the transfer of goods or services, i.e. dispatch of goods is known as the Delivery Cycle.

It consists of throughput time, Value added time and non-value added time.

To depict delivery cycle in the formula form, the following formula maybe used:

Delivery Cycle = Value added Elements of Throughput Time + Non Value Added Elements of Throughput Time.

Manufacturing Cycle Efficiency is an internal business performance parameter with respect to manufacturing processes and industries. It measures the total time taken by value added activities in relation to the throughput time.

Hence evaluation has to be done of the following parameters:

Throughput time
Delivery Cycle Time
Manufacturing Cycle Efficiency

To determine

Areas where company’s performance is improving.

Areas where company’s performance is deteriorating.

Expert Solution

Answer to Problem 19P

Solution:

Areas where company’s performance is improving are None
Areas where company’s performance is deteriorating are throughput time and delivery cycle time and manufacturing cycle efficiency.

Explanation of Solution

Throughput time comprises of two main categories of elements i.e. Value added and Non Value added elements.

Value added elements refer to the time taken for those activities that add quality and value to the overall production process concerning manufacture of goods. Example − Process Time.

Non Value added elements refer to the time taken for those activities that do not add quality and value to the overall production process concerning manufacture of goods and that need to be eliminated to the greatest extent possible. Example - Inspection Time, Move Time and Queue time

Following are the Throughput time for four months:

	Average Time per month (in days)
Particulars	1	2	3	4
Throughput Time	7.30	8.10	8.80	9.60

Since the total throughput time is increasing, it can be said the company’s performance is deteriorating.

The time taken from the start of the sale process, i.e. the receipt of a confirmed sales order, to the completion of the transfer of goods or services, i.e. dispatch of goods is known as the Delivery Cycle.

Following are the Delivery cycle times for four months:

	Average Time per month (in days)
Particulars	1	2	3	4
Delivery Cycle	16.30	19.60	20.80	23.60

Since the total delivery cycle time is increasing, it can be said the company’s performance is deteriorating.

Manufacturing cycle efficiency helps keep track of where time and cost is incurred in non-value added activities and performance efficiency measurement.

Manufacturing cycle efficiency is denoted by the following formula:
Manufacturing cycle efficiency = Time Taken by value added activities / Total Throughput Time.

Total Throughput Time = Time Taken by value added activities + Time Taken by Non value added activities

For example if the time Taken by value added activities is 25 minutes per unit and the Time Taken by non-value added activities is 35 minutes then manufacturing cycle efficiency would be 0.42.
Thus it can be interpreted as, the value added activities take up only 42 % of the total time taken to complete the manufacturing process and the rest is attributable to non-value added activities.

Following are the Manufacturing cycle efficiency for four months:

	Average Time per month (in days)
Particulars	1	2	3	4
Manufacturing Cycle Efficiency	0.29	0.25	0.22	0.19

Since the Manufacturing Cycle Efficiency is decreasing, the company’s performance is deteriorating.

Conclusion

Hence the performance measures where the company’s performance is increasing and decreasing are enumerated.

Throughput Time	9.60	2.90

Manufacturing Cycle Efficiency for month 5	0.19	0.62

Explanation of Solution

Throughput time comprises of two main categories of elements i.e. Value added and Non Value added elements.

Value added elements refer to the time taken for those activities that add quality and value to the overall production process concerning manufacture of goods. Example − Process Time.

Process time is the time spent on actually producing the product. It refers to the time taken to convert the goods from raw materials to interim or final finished products

Non Value added elements refer to the time taken for those activities that do not add quality and value to the overall production process concerning manufacture of goods and that need to be eliminated to the greatest extent possible. Example - Inspection Time, Move Time and Queue time

Inspection time is the amount of time spent assuring that the product is defect free to the best possible extent

Move time is the time required to transfer raw materials or interim or final finished products from one location to another, such as factory to job workers’ location.

Queue time is the amount of time that is spent waiting for the actually production activities to commence since other products are being produced or worked upon.

Answer 28

Explanation of Solution

Throughput time comprises of two main categories of elements i.e. Value added and Non Value added elements.

Value added elements refer to the time taken for those activities that add quality and value to the overall production process concerning manufacture of goods. Example − Process Time.

Process time is the time spent on actually producing the product. It refers to the time taken to convert the goods from raw materials to interim or final finished products

Non Value added elements refer to the time taken for those activities that do not add quality and value to the overall production process concerning manufacture of goods and that need to be eliminated to the greatest extent possible. Example - Inspection Time, Move Time and Queue time

Inspection time is the amount of time spent assuring that the product is defect free to the best possible extent

Move time is the time required to transfer raw materials or interim or final finished products from one location to another, such as factory to job workers’ location.

Queue time is the amount of time that is spent waiting for the actually production activities to commence since other products are being produced or worked upon.

Given:


Particulars	4	5

Move time per unit	0.5	0.5
Queue Time per unit	6.7	0.0
Inspection Time per unit	0.6	0.6
Process Time per unit	1.8	1.8

Formulas Used:

Total Throughput Time = Time Taken by value added activities + Time Taken by Non value added activities (Except Wait Time)

Manufacturing cycle efficiency = Time Taken by value added activities / Total Throughput Time.

Time Taken by value added activities = Time taken for Process Time

Time Taken by Non value added activities = Time taken for Move Time + Queue Time + Inspection Time

Calculations:

	Average Time per month (in days)
Particulars	4	5

Move time per unit	0.5	0.5
Queue Time per unit	6.7	0.0
Inspection Time per unit	0.6	0.6
Total Time For Non Value Added Activities (A)	7.8	1.1
Process Time per unit	1.8	1.8
Total Time For Value Added Activities (B)	1.8	1.8
Throughput Time (A+B) [C]	9.6	2.9

Manufacturing Cycle Efficiency	Time Taken by value added activities / Total Throughput Time.
Manufacturing Cycle Efficiency	0.19	0.62

Since it is given that the lean production has eliminated the queue time, the same is not considered.

Answer 29

Conclusion

Hence the throughput time and manufacturing cycle efficiency has been calculated for month 5.

Throughput Time, Manufacturing Cycle Efficiency

The time taken from the start of the sale process, i.e. the receipt of a confirmed sales order, to the completion of the transfer of goods or services, i.e. dispatch of goods is known as the Delivery Cycle.

It consists of throughput time, Value added time and non-value added time.

To depict delivery cycle in the formula form, the following formula maybe used:

Delivery Cycle = Value added Elements of Throughput Time + Non Value Added Elements of Throughput Time.

Manufacturing Cycle Efficiency is an internal business performance parameter with respect to manufacturing processes and industries. It measures the total time taken by value added activities in relation to the throughput time.

Answer to Problem 19P

Solution:

	Average Time per month (in days)
Particulars	4	6
Throughput Time	9.60	2.30

Manufacturing Cycle Efficiency for month 6	0.19	0.78

Explanation of Solution

Throughput time comprises of two main categories of elements i.e. Value added and Non Value added elements.

Value added elements refer to the time taken for those activities that add quality and value to the overall production process concerning manufacture of goods. Example − Process Time.

Process time is the time spent on actually producing the product. It refers to the time taken to convert the goods from raw materials to interim or final finished products

Non Value added elements refer to the time taken for those activities that do not add quality and value to the overall production process concerning manufacture of goods and that need to be eliminated to the greatest extent possible. Example - Inspection Time, Move Time and Queue time

Inspection time is the amount of time spent assuring that the product is defect free to the best possible extent

Move time is the time required to transfer raw materials or interim or final finished products from one location to another, such as factory to job workers’ location.

Queue time is the amount of time that is spent waiting for the actually production activities to commence since other products are being produced or worked upon.

Given:


Particulars	4	6

Move time per unit	0.5	0.5
Queue Time per unit	6.7	0.0
Inspection Time per unit	0.6	0.0
Process Time per unit	1.8	1.8

Formulas Used:

Total Throughput Time = Time Taken by value added activities + Time Taken by Non value added activities (Except Wait Time)

Manufacturing cycle efficiency = Time Taken by value added activities / Total Throughput Time.

Time Taken by value added activities = Time taken for Process Time

Time Taken by Non value added activities = Time taken for Move Time + Queue Time + Inspection Time

Calculations:

	Average Time per month (in days)
Particulars	4	6

Move time per unit	0.5	0.5
Queue Time per unit	6.7	0.0
Inspection Time per unit	0.6	0.0
Total Time For Non Value Added Activities (A)	7.8	0.5
Process Time per unit	1.8	1.8
Total Time For Value Added Activities (B)	1.8	1.8
Throughput Time (A+B) [C]	9.6	2.3

Manufacturing Cycle Efficiency	Time Taken by value added activities / Total Throughput Time.
Manufacturing Cycle Efficiency	0.19	0.78

Since it is given that the lean production has eliminated the queue time and inspection time, the same is not considered.

Conclusion

Hence the throughput time and manufacturing cycle efficiency has been calculated for month 6.
