Exercise 1: Wastes Identification
1. List at least one example of each of the 9 categories of waste
from a process within your organization.
2. Identify at least one possible cause for each of the specific
wastes listed.
3. Propose one or more actions to reduce each of these wastes.
4. Identify methods of measurement to determine results of
waste reduction efforts.

We will learn to:
• Recognize our lead-times
• Identify their components
• Reduce them with the help of
– the dedicated lines
– a one piece flow
• Establish dedicated lines
– in relation to family of parts
– in relation to TAKT time
• Attain one piece flow

manufacturing lead time:

How to Use This Manual
The continuous improvement tools that are presented in Sections 1-9 of this manual are shown in order of
use. These forms MUST be completed in the order presented in this manual. Each section contains a brief
description of the tool, its purpose, when to use it, who should use it, how to use it, and the expected
results.
Remember to focus on the elimination of waste. Strive to maximize yields and obtain
cost reductions from existing machinery and equipment before “buying solutions”.
Improve current systems and techniques before automation. Automating a system or
practices without first having an understanding of the process will not solve underlying
process problems.
Perhaps the most important point to remember is that we must understand a process
before we make any attempt in changing it. “No Tampering” is the first rule of
continuous improvement. We can not tamper with a process without understanding it.
By using these tools, we will all share a common and systematic approach for
questioning, analyzing, proposing solutions, experimenting, and finally, implementing
proven changes.
“The problems that exist in the world today
cannot be solved by the same level of thinking
that created them.”

Time Observation Form
Purpose
Used to identify each task performed in a process or section of a process.
Further used to identify actual times for each task in order to determine the
overall process cycle time.
When To Use
The Time Observation Form (TOF) should be used after the Standard Work
Sheet and Spaghetti Diagram have been completed.
Who Should Use It
The Time Observation Form can be used by anyone involved in continuous
process improvement.
Expected Benefits
The Time Observation Form will provide information about work sequence,
work content, and operation times. The TOF not only provides actual times,
but also provides best demonstrated performance, on the specific process
being analyzed.
How to use it
1. Complete Sections A. B, and C. with the necessary information.
2. Fill in the Task Component blanks with the steps of the process. List the components in as
specific terms as possible, i.e., 1. Walking to get work piece. 2. Removing work piece from
basket. 3. Walking to machine. 4. Loading piece into machine. And so on.
3. Begin timing the tasks. As each task is completed, stop the watch and record the cumulative
time on the form. Continue recording task times in this manner until the end of the process
cycle
4. At the completion of 12 full cycles, calculate and enter the “Assigned Component Time” for
each “Task Component”. Then sum up the “Assigned Component Time” for each “Task
Component” and enter this into the “Time For One Cycle” field. Be sure to include the time
spent on closing out work orders, or moving parts to next job.
5. During the manufacturing process, be aware of the steps taken to perform the job, i.e. If a
particular task component varies from 4 second for observation #1 and 47 seconds for
observation #2, provide comments about the observed variance in the remarks column.
Remember, in our quest to remove waste from the process, we want to question every task
component of the process.
6. Once the actual cycle times are known, compare them to TAKT time. TAKT Time for
measurable, repetitive task processes is calculated as follows:
A. Calculate the total time available per shift, day, etc. excluding breaks and lunches.
Let’s say that we have a full 8 hours available. 8 hours would equal 480 minutes or
28,800 seconds.
B. Determine the required product quantity. [How many units have been sold] For this
example, let’s use 395 units for the required production for this operation.
C. Next, divide the total time available by the required production to arrive at the TAKT
Time. 28,800 / 395 = 73 seconds per unit.
D. Compare this TAKT time to the average cycle time of the observation.
1.
2.
If TAKT Time is greater than average cycle time, then we can conclude that
the required production can be met within the total time available. However,
we need to examine adding work from another process to minimize idle time.
If TAKT Time is less than average cycle time, then we can conclude that the required production cannot be
met within the total time available. We must eliminate work through Kaizen or transfer work to another
worker.
