ME503 FINAL EXAM QUESTIONS AND VERIFIED
ANSWERS
The Takt time is the rate at which a production line can manufacture items.
(True or False)? - Answers - False
Which Statement does not reflect the view of standardized work in lean?
a. Standardized work is the most efficient known way to manufacture a product.
b. Standardized work is a way for management to impose production rates on a
workforce.
c. Standardized work in lean should be updated regularly.
d. The employees on the line should be involved in establishing standardized work in
lean. - Answers - b. Standardized work is a way for management to impose production
rates on a workforce.
The three basic elements of information that must be included in standardized work are:
Takt time, work sequence and WIP levels. (True or False)? - Answers - True
Standardized work can serve as an improvement baseline.
(True or False)? - Answers - True
Standardized work deters creativity in team members.
(True or False)? - Answers - False
Which of the following is not correct about standardized work?
a. It can help build quality and reduce cost.
b. It can help avoid overproduction.
c. Standardized work helps to identify opportunities for improvement..
d. Standardized work must be updated annually. - Answers - d. Standardized work must
be updated annually.
Changes in customer demand can necessitate changing the takt time. However, too
frequent takt time changes can be costly as it will require changing all standardized
work. How can you avoid takt time changes when product demand increases by a
, moderate amount? Use a simple numerical example to elaborate your answer. -
Answers - Takt Time = Total Time Available / Total Customer Demand
Standardized work is one of the most important tools used in a lean manufacturing
environment. Five of the primary reasons for their usefulness/significance were
discussed in the lecture. Describe three of these reasons (one sentence each). -
Answers - I. Problem Identification
II. Respect for Customers
III. Improvement Baseline
IV. Improvement Measurement
V. Real Time Status Monitoring
A standardized work sheet developed by a team at Lexington Iron Works is shown
below. Based on the principles discussed in the lectures, describe what additional
information must be included here to make it a useful tool for continuous improvement.
In your answer, you must identify at least 4 types/pieces of information that is not
included and discuss what they are. - Answers - Additional information that must be
added is symbols for safety points, quality checks, and WIP's such as + signs for safety,
diamonds for quality checks, and dots for WIP's.. Another piece of information that must
be added is arrows connecting each task, these will make comprehension of work flow
easier. Takt time is another piece of information that is not included, takt time is the time
between successive parts going out of a system. Finally, wait and walk times must be
recorded as well. This represents the time used transporting or waiting on
machines/other workers.
Changes in customer demand can necessitate changing the takt time. However, too
frequent takt time changes can be costly as it will require changing all standardized
work. How can you avoid takt time changes when product demand increases by a
moderate amount? Use a simple numerical example to elaborate your answer. -
Answers - Takt time changes can be avoided by changing the total time available. If
product demand increases, total time available must increase as well to keep takt time
stable. THis could be done by extending the shift period, taking time out of breaks, or
finding new ways to save time in the production process.
Example: Current takt time is 60 seconds (420 minutes available / 420 units
demanded). The demand increases to 450 units. To avoid takt time changes, you must
add 30 minutes to the end of each
We discussed that achieving one-piece flow between stations is not always feasible.
Supermarkets and kanbans must be used in such situations. Describe two situations
that would prevent one-piece flow between two stations and explain why they act as
barriers ( no less than 2-3 sentences for each situation). - Answers - One situation is
