Executive Summary
Goodwill Industrial Services, Los Angeles, had a problem—their factory floor could not
accommodate multiple product processes, which they believed resulted in the department
hitting a profit plateau. It was also observed that there was a problem with the hanger
sorting process. It had been done in the department longer than any other product;
however, it took up an enormous area for processing and storage of unsorted, in process,
and sorted hanger boxes. Another perceived issue was a lack of standardization in the
method for approaching new products and services.
To tackle the first problem of the hanger process, profitability was calculated with respect
to the amount of space it required—for both the work itself and storage. This number
was compared to another common product that used far less space—specifically Paul
Mitchell Products. Using historical data and space requirements, it was determined that
the hanger sorting process earns $0.20/day per square foot of floor space while Paul
Mitchell earns nearly four times as much at $0.79/day per square foot. After analysis of
these numbers it was concluded that ideally, the hanger sorting process should be
removed because of the inefficiency inherent to the process. Improving the process itself
was deemed futile because the process would still require a large amount of storage space
regardless of the improvements made within the process.
At present, however, the hanger sorting process cannot be removed from the department
because there are mentally and physically handicapped client-employees that cannot do
anything else except sort and pack hangers. Taking this into account, it was
recommended that it be confined to the back area of the factory floor (see Appendix K).
This way the large amount of boxes needed to complete the process will not interfere
with the other processes of the factory. Different function levels of workers were
separated within the hanger process layout so as to balance the production line and
smooth the flow of product within the different function areas.
In regards to all other product processes, there are two different types of products—one
where only one or two tasks must be done to complete the task (e.g. placing a sticker, or

4. 2
dressing a doll), and one where many tasks must be completed to create a finished
product. Layouts were created for individual groups processing each product type
overseen by one or two team leaders; this is how the factory is presently managed (see
Appendix H & I). Both layouts include ideas and suggestions for line balancing and flow
smoothing.
To help the supervisors better assign client-employees to the tasks required for a process,
the “Hourglass Flow Model” was created (see Appendix D). It breaks down the
fundamental elements of all products received and shows how the difficulty and
complexity of each task relates to its location in the overall flow from raw material to
finished good. This model is applicable to every category of product and layout.
If for some reason, the hanger process is eliminated from the Los Angeles facility, a
factory layout that did not contain hangers was included (see Appendix J). This layout
can accommodate up to four different product processes and has a smooth and logical
flow.
In all layout models, safety was assured by maintaining the preexisting dotted yellow-line
in the factory. This line separates the work areas from the forklift traffic lane and assures
an unobstructed path to the emergency exit and fire extinguisher. The location of pallets
is such that the forklift can easily access them without infringing on the work areas. It
was also suggested that all raw material pallets be deposited after regular work hours and
in a quantity that can be worked through in at least one day for each process in the
factory. This insures that there is little forklift traffic during the busiest hours, which
reduces risk of accidents.
Given the proposed layouts, a list of the materials and equipment that were needed on the
factory floor was made. This list does not account for any equipment already existing. It
should be mentioned that Goodwill Industries, Los Angeles does not currently have the
man power or customer base to employ our layouts fully. They should be considered an
attainable goal that, when reached, should result in increased profits, improved utilization
of the factory floor, and an all-around safer work environment for everyone.

Introduction
Goodwill Industries of Southern California funds programs that train unemployed and
underemployed men and women so that many will be able to transition into a mainstream
work environment with the proper skills and work habits. As shown in its organizational
values, Goodwill is dedicated to helping people help themselves. Goodwill encourages
the workers, called client-employees, to strive to achieve their highest potential, since
their needs are the reason why the organization exists. The Los Angeles facility was the
focus of our project, being the largest of the three facilities in the greater Los Angeles
area, and providing a greater opportunity of improvement. More specifically, we worked
with the Industrial Services division which forms contracts with outside companies to do
the simple tasks for them such as sorting and packaging the goods. Some of these
companies include Paul Mitchell hair products and Auntie-Itch cream products.
Employees
The client-employees who work on the tasks daily include people with physical or mental
disabilities and other vocational disadvantages. There are three levels of client-
employees—low, medium, and high-functioning. They are placed into one of these
categories based on their abilities. An outside work environment is not an option for low-
functioning client-employees, because their disabilities or barriers are too severe to allow
for a successful transition outside of Goodwill. Therefore, Goodwill provides them a
long-term work opportunity that builds in them a sense of accomplishment and pride in
their work.
The low-functioning client-employees can only perform single or simple tasks. Some
examples of the capabilities and responsibilities of low-functioning client-employees

7. 5
include executing a “yes” or “no” decision, wrapping or unwrapping a product, sorting,
packing a single item into a box, and performing checks (such as whether a cap is
tightened or not). The abilities of medium-functioning client-employees are very similar
to the low-functioning client-employees; however, they can perform two tasks
simultaneously. For example, a medium-functioning client-employee can sort and pack,
whereas a low-functioning client-employee can only sort or pack.
For high-functioning client-employees, the work experience that Goodwill provides them
must be “meaningful,” so that the individual can be trained for successful transition into
outside employment such as mail house or assembly environments. Some of the work
skills and work habits that are taught to the client-employees are attendance, hygiene,
inter-personal interactions, communication skills, work place conduct, and following
directions. High-functioning client-employees can perform more complex tasks and
make multiple decisions, some of which include lifting, heat-sealing, labeling, and
packing multiple items. Lifting is usually performed by high-functioning client-
employees because of its physical nature. Client-employees with physical and more
severe mental disabilities would not be able to perform such a task. Heat-sealing is one
of the more dangerous tasks and requires that the client-employee understand the safety
considerations of the task. Labeling is left to the high-functioning client-employees
simply because it requires accuracy of label placement, especially for the smaller
packages and boxes.

8. 6
Material handler is the name given to a high functioning worker; however, he or she is
not classified as a client-employee for several reasons. They are much more able-bodied
to carry out physical tasks such as unloading packages, staging, shrink-wrapping
completed pallets, palletizing and de-palletizing, and distributing materials to the client-
employees. Material handlers are also given an hourly wage, rather than being paid by a
prorated piece-rate based on minimum wage, which is how the client-employees are paid.
Material handlers are classified as high-functioning, not necessarily because of the
complexity of the tasks, but because of the number of concurrent tasks that they are
assigned to do. The material handlers are responsible for many more duties than the
client-employees, especially the tasks at the beginning and at the end of the production
line.
The Hourglass Flow Model
Picture 1
The Hourglass flow model is a representation of
the flow of each product from the beginning
the end of the production process. As seen in
to
Picture 1, the complex tasks are those involving
the raw materials and finished goods. In these
areas, high-functioning workers are needed in
order to accomplish these tasks. After the
material handlers have prepared the raw
materials to be worked upon, the lower-

9. 7
functioning workers can perform the simpler tasks. Then the product returns to the
material handlers who then complete the tasks at the end of the production process. T
Hourglass flow of the work break down sheet can be observed in Chart 1.

amount of time it takes to perform each task, the pay rate for performing each task, and
hourly wages. By examining the tasks more closely, one can see that the Hourglass
model is in fact being followed. As noted in Chart 1, the tasks in the beginning and at th
end of the production process are being performed by the high-functioning material
handlers, while the work of the lower and medium-functioning client-employees are
clustered in the center of the process.

Another example supporting the Hourglass flow model, found in Chart 2 above, is for the
hanger process, which Goodwill has been doing for a long time. The material handlers’
jobs are not listed in the tasks, but are being executed. In the beginning of the process
material handlers bring the unsorted boxes of hangers to the warehouse and distribute
them to the client-employees. The low and medium-functioning client-employees then
sort out the different types of hangers, and pack them into separate boxes. Finally, the
material handlers once again perform their duties on the completed hanger boxes.
Having different levels of client-employees exacerbates the difficulty of creating an
efficient flow in the main warehouse.

Hangers
The hanger process is quite simple, yet very time and space consuming. There are about
t types of hangers. The hangers are then sorted using a hanger sorting

apparatus which facilitates the sorting operation, yet can only be done by a high
functioning client-employee. Currently the unsorted boxes contain about 3 or 4 di
types of hangers which even a low function client-employee can individually sort
and separate. A worker has to pick up each individual hanger and decipher the type, and
place it in the box it belongs to. The hangers are then neatly packaged into individual
boxes, which usually hold at least 100 hangers of one specific type.
Disadvantages
The whole hanger process is very time consuming. Each client-employee has to figure
ich type of hange
to pick it out of a box with many hangers, which are usually tangled in one way or
another, and looking at it carefully because many of the hangers look very similar. If the
client-employee is just sorting, then they put it in another box without worrying that
neatly placed. If the client-employee is sorting and packing, then they have to carefully
place it neatly in the packaging box. Whether the client-employee is only packing, or
sorting and packing, they will be surrounded by at least 4 large boxes, which leads to the
next point.

12. 10
The hanger process is very space consuming, because each client-employee needs at least

he results indicate that a Paul Mitchell product is much more profitable considering the
4 boxes around them to be able to place the hangers in the correct box. This takes up a
lot of useful floor space because many times they might have 6 or 7 boxes around them,
which are not put to use. Also, because of the high turnaround time, the unfinished and
finished boxes take up a lot of space as was discovered during our many visits to
Goodwill Industrial Services. The turnaround time has improved, but hangers are
very much space consuming.
T
includes space for the process itself and for raw and finished materials. Hangers account
for nearly 60% of the revenue, but use over 75% of the whole facility space. One needs
to look at the product profitability in dollars per square foot between hangers and a Paul
Mitchell.

difficult because every worker is working at their pace. Also, the hanger process is ver
time consuming meaning some workers only finish about one box a day. Although the
client-employees are being paid according to their number of completed hanger boxes,
they are taking up a certain amount of space on the factory floor which can otherwise be
used for more profitable products. Furthermore, they are slowing the hanger process,
which can lead to starvation or a high turnaround time.
Advantages
Goodwill Industrial Services many times serves solely as a transition period for the
client-employees. They begin to work and learn at Goodwill Industrial Services, and
when the client-employees reach an adequate skill level, they are transferred to higher
skill demanding employment.
T
low-skilled client-employee can be employed to either sort or package hangers. They
also do both, although most start off by just doing one of the tasks. Here, many low-
skilled client-employees can be used which would otherwise not have any value-addin
tasks. Furthermore, the low-skilled client-employees gain familiarity with the hangers,
increasing their productivity over time.

hanger process is always available to be worked on.
The hangers should be eliminated to provide more space for other more profitable
products to come through Goodwill Industrial Services. If the hangers are to be kept,
they are to be kept solely for the advantages listed.

This is a product that, after initial de-palletizing and staging, requires only one or two
tasks before it can be re-boxed and re-palletized. An example of an actual Goodwill
single-task product is the “Scoobie-Doo doll”. After the dolls are staged for the clien
employees, it has to be removed from its bag, dressed and attached to a costume. Then
is placed back in the bag and sent off to be re-boxed. What makes this category
important is that all the tasks required (save the material handlers’ tasks) can be
completed by one person or up to three people in a small sub-group and few mate

adhered to them, then be placed in their individual boxes, then have another sticker
placed on the front and back of the box, and finally be placed inside larger boxes which
are then taped and palletized. This product type requires a more traditional assembly
setup and each station requires intermediate materials to complete their tasks in contrast
to the single-task product that requires only what is in the initial palletized box.

so as to better keep track of a client-employee’s production. The proposed setup does
allow a product to continue after the client-employee has worked on it until the team
leader marks down their progress and places the item on the conveyor in the center.
From there it simply continues down the conveyor to the material handlers for boxing a
re-palletizing. Another change proposed is the implementation of the use of hand
the material handlers. Note: This proposal is not unique to the single-task produc
line; rather it is an overall factory-wide improvement suggestion. The use of handcarts
allows for more products to be distributed at one time by a material handler improvin
their efficiency. It also improves the overall ergonomic safety of the material handlers
requiring them to lift much less weight at one time. The material handlers with han
will take material from the raw material pallet and distribute the material to the memb
of both lines for work. Since each station does all the tasks required of the product (see
definition of single-task product) excluding staging and re-palletizing, the product goes
directly from each station to the conveyor (see blue product flow arrows). It was
previously said that all tasks are to be completed by one individual or a small sub-group
of no more than three. These sub-groups are displayed by a dotted square around them.
The members of this sub-group break up the tasks and each complete an entire produc
together. This is why there is only one arrow leaving each of these subgroups.

employees, each individual or sub-group is seen as the only intermediate step betwee
material handlers’ tasks. Since the client-employees will logically be working sl
than the material handlers, the only place where production flow needs to be analyzed
and controlled is within the sub-groups because they have more than one person affecti
production flow. Our recommendation is that within a particular sub-group, each clien
employee is of the same function level and works at the same pace. This can be seen on
our drawing that each member of a sub-group is of the same function level. By doing
this, it assures that there will be no bottlenecks or starvation within the sub-group and the
product will spend an equal amount of time with each person in the sub-group before
being placed on the conveyor. It should be mentioned that it could occur where the tasks
performed within a sub-group are not the same level of difficultly. In this situation, a
higher functioning worker should do the more complex task and a lower functioning
worker should do the simpler task. Another option would be to have two lower
functioning workers doing a simpler task to feed the higher functioning worker so as n
to starve his supply. In a single-task product, these aforementioned situations wi
occur often so a best guess judgment should be applied using these suggestions and the
layout as a base model.

Since there are multiple tasks to complete, a more traditional assembly-line model was
applied. This means that the tables and work surfaces act as the conveyor and the client-
employees will advance the product down the line. The area between the two table lines
allows enough room for two people to comfortably pass one another. It is assumed that
each team leader would be responsible for one table line. They would keep trac

perform a slightly different function. Raw material is deposited at the first station, ei
by the staging crew or the handcart pusher, but at all the other stations, the handcart

logical method of client-employee function distribution. This distribution is dictated by
the product being worked through and the complexity of tasks therein. The client-
employee function distribution must be applied in a way that smoothes production
balances the line. As mentioned earlier, this reduces bottlenecks and starvation at each
station. Before client-employees can be assigned to their respective tasks, the complexit
of each step and type of client-employee that can effectively perform the task must be

23. 21
understood. After this, client-employees should be matched up with the most complex
tasks they can effectively perform. Doing this will normalize the throughput at each
station by having a faster worker perform a harder task and a slower worker perform a
easier task. After this is done, more tweaking may still be necessary. In a situation
where a station is being starved because the previous station is not working fast enou
it is recommended that an extra client-employee is put on the slower station to double the
input into the station that was once starved. In a situation were product is being
bottlenecked at a station because the client-employee is working too slowly for th
previous station, placing an extra worker on this station will speed up its throughput
Before additional workers are placed at a station in an attempt to solve flow problems,
production line and the effect of additional staff on the whole production must be
considered. As mentioned in the single-product layout, the material handlers are th
fastest workers and need not be considered in the smoothing of production flow; they
pace their material distribution as dictated by the client-employee production rate.

unnecessary equipment, and the handcarts stored there are now being used by the
material handlers at each group. The factory floor has four main sections, the uppe

different product lines being processed simultaneously in each of the four areas. We

work hours to assure everyone’s safety. The amount of product delivered to this area
shall be at least one day worth of work per production line. This assures that no
deliveries must be made during regular work hours. Material handlers will move the
pallets (using already available pallet jacks) to their respective staging areas. The
flow through the production lines is dependent on the type of product (single or multi-
task). The production lines shown in the factory layout are just an example of what can
be used, however it should be noted that the single-task production line requires slightl
more space due to the additional width of the conveyor. This adds 2 feet to the
production line width which makes it difficult to put two production lines in an area other
than the lower-left corner since this corner is the widest. The areas at the top of
factory floor can be used either for single or multi-task production. They are oriented
horizontally; this allows for the added width of the single-task production line. The
upper-right corner is a smaller area and restricts the length of any production line from
feet to 22 feet. The
production lines at the

on the outside of the factory floor and fed through the production lines to the finished
goods in the center. After a finished goods pallet is created, the material handler (using
the pallet jack) moves the pallet to the yellow-dotted line on the edge of his respecti
work area. From here, the forklift can easily move material out of the factory and prepa
it for shipping. The forklift is not restricted from picking up finished goods pallets
outside of regular client-employee work hours because the location of the finished goods
pallets does not require the forklift to enter the work areas marked by the dotted yellow
line. The production lines in the

Proposed Factory Layout (with hangers)
The hanger sorting process is placed in the back or upper-right and left corners of the
factory floor. This was done because of the large amount of space and boxes and raw

26. 24
material required of the process—it was placed out of the way of other processes as not to
impede on their flow rates due to
excess boxes. The bottom portion
of the factory is identical to the
previous layout with the exception
that the hanger process took up too much room to have a row of raw materials on both
sides of the floor. This row is now confined to the right side, and this group of raw
materials supplies both non-hanger production lines in the lower portion of the factory.
Raw material for hangers is now stored in the back of the warehouse in the center. The
process is broken up into two areas—one for medium functioning client-employees
(yellow in the upper-left) and one for low functioning client-employees (red in the upper-
right). Each area has its own supply of raw materials which is deposited by the forklift in
the same manner as the previous layout—at least a day’s worth of raw material for each
area.
In the low-functioning area material is deposited to the row of client-employees on the
top by the material handlers. The client-employees take hangers from the unsorted (light-
colored) box and sort them into
their respective boxes below them
(slightly-dark colored). From here
the material handlers take the
sorted hangers from the top row of
client-employees and deposit them
into the bottom row of low-functioning client-employees as needed. These client-

27. 25
employees pack the hangers neatly in boxes (very-dark colored). From here the material
handlers take the packed hangers to the finished goods area in the medium-functioning
area upper-left corner area (follow the blue arrow). Here a material handler weighs,
counts, seals, and re-palletizes the hangers onto pallets at the each of the work area where
the forklift can access them easily. The low-functioning area could not have its own
finished goods area because of space constraints, however, the output of the low-
functioning area is very low so the amount of product that flows across the floor to the
finished goods area is extremely low and will not require much labor.
In the medium-functioning area material is deposited to each of the three rows of
medium-functioning client-employees

Unlike the low-functioning client
employees, there is no intermediate step
between sorting and packing. Medium
function client-employees take the
unsorted hangers from the box where
material handlers originally deposited them (light-colored box) and then sorts and packs
them in the boxes below them (very-dark colored box). From there, the material handlers
take the packed and sorted boxes to the finished goods area where a material handler

unlikely that the material handlers will have too much work to do in these areas. They
could possibly “moonlight” in other production areas.
Smoothing Production Flow
To effectively smooth production flow in the hanger processing area, both the material
handlers and the team leaders need to keep an eye on how fast client-employees are
working. Since client-employees are not working from a table rather from a box, it is
unlikely that starvation will occur. If one low functioning client-employee is starved by
having no hangers to pack, that client-employee can be re-assigned to sorting until
enough sorted hangers are produced to justify a packing client-employee. The ratio
between the sorting and packing client-employees in the low-functioning area (upper-
right) can therefore be tweaked to smooth production. In the medium-functioning area,
the client-employees do both sorting and packing therefore it is infeasible for there to
bottlenecks and starvation within an individuals work area. Smooth production is simply
produced in this area by insuring each medium-functioning client-employee has enough
hangers and that all packed and sorted hanger boxes (very-dark colored) are taken to the
finished goods area in a timely manner. It is therefore ultimately up to the material
handlers and the team leaders to assure smooth production in the hanger processing area.

Conclusions
Total equipment needed on hand for increased utilization:
• 130 adjustable stools
- They need to be adjustable to fit each person’s height to provide the correct
working posture. They also need to be rotary, for the client-employees working
on the hangers can easily turn to place hangers in specific boxes.
• 24 low tables for hanger sorting
- The tables need to be low so the client-employees have an easier time reaching
into the boxes to pull out the hangers. It will decrease muscle strains and decrease
sorting and packaging times.
• 32 regular standard height tables
- These tables are needed for other product processes.
• 2 wheelchair height tables
- These need to be available for the client-employees who are wheelchair bound.
• 6 carts
- With these carts material handlers can easily transport raw and finished materials
from the client-employees to the unfinished and finished crates. This will lessen
the physical work material handlers have to do decreasing the chances for injury.
To increase flow through a production line, the hourglass theory was proposed. This
stated that the high functioning client-employees are to be placed at the beginning and
end of processes, while the medium and low functioning client-employees dually
working in the middle of the line, to balance the product flow. To increase overall
factory utilization different layouts with production lines have been proposed. These
layouts augment productivity through the specific placement of raw materials, client-
employees, supervisors, and finished goods. In these layouts it is recommended that the
heat-sealing machine and the hanger process be removed for financial reasons.

30. 28
Removing them would greatly increase the amount of available space for our proposed
layouts as well as increase revenue. If the hangers are to be kept, then a layout is
proposed where the hanger process would not hinder the rest of the factory floor flow.
The use of the layouts will also increase worker and space utilization. With this, profits
will increase while creating a safer working environment which will ultimately lead to
better products.
