Mexican BurgerMac, Inc.
Copyright © 2024 by Robert Wayne Atkins, P.E.
Mexican BurgerMac, Inc. is a new worldwide Franchise Restaurant. Their advertising campaign is
based on fresh, high-quality food that is not cooked until after the customer places an order. The
customer has to wait a few minutes longer to get the food, but that food is worth the short wait because
it is cooked fresh to the customer’s exact specifications. This includes all hamburger meat patties,
sausage patties, strips of bacon, pancakes, eggs, hash brown potatoes, chicken, fish, hush puppies, taco
shells, and pizzas. The only precooked food items are sandwich buns, biscuits, nacho chips, and
burrito shells. Everything else is cooked fresh (or heated) after the customer places an order. Most of
the fresh food is stored in a Refrigerator until the Cook needs it to fill an order.
All the Work Measurement and Ergonomics Chart Forms should be constructed from the perspective
of a Cashier who works behind the front counter at the restaurant. You should assume that one
Cashier does all the work of assembling the entire Food Order ordered by the customer.
Each Work Measurement Chart should clearly document the entire Food Order activities from
beginning to end. Do not include preparing any of the food items typically performed by the Cook.
Only include the work performed by the Cashier. Each customer’s order is entered into the cash
register computer on top of the front counter. The Cashier determines exactly what items the Food
Order consists of.
Each Work Measurement Chart should begin with the first thing the Cashier must do after she
understands what Food Order is to include.
Each Work Measurement Chart should end with the Cashier handing the Food Order To-Go bag to the
Customer and then the Cashier should return to the starting position behind the front counter. This
completes one full order cycle for the Cashier.
(Note 1: The Cook is a different employee, and the Cook will not be considered in this analysis.)
(Note 2: Each walking activity inside the kitchen takes 5 seconds to get from one location to the next
location regardless of where the cashier begins and ends the walking sequence.)
Cashier Example
All of the following operations and materials must be included in your analysis:
1. enter the customer’s order into the Cash Register Computer.
2. receive Cash from the customer and give Change to the customer (or scan credit card),
3. one Soft Drink Cup to the customer,
4. one To-Go Paper Bag,
5. tape the Printed Order Ticket to the Bag,
6. read the customer order and remember what food items to put into the Bag.
7. one Cheeseburger into the Bag,
8. transfer loose French Fries into a French Fry Bag and then put the Fries into the To-Go Bag,
9. one Paper Napkin into the Bag,
10. two Ketchup Packets into the Bag,
11. give the To-Go Bag to the customer.
12. return to cashier’s station.

The Following Time Values Apply to this Cashier Job
You must determine the most efficient way for the Cashier to fill the Customer Order so the Entire
Order can be delivered to the customer in the shortest period of time.
The following work elements are not listed in any special order. The following categories may not be
listed in the best sequence in which they should be done by the Cashier. However, once a set of
activities has begun within a category the other activities in that category must be continued to its
logical end. In other words, you cannot change the sequence of the events within each of the
following major categories. However, you may rearrange the following broad categories into the best
sequence that would result in the shortest waiting time for the customer. The Cashier may also be
working on more than one category at the same time if he or she is not busy doing something else.
Take Customer Order and Collect Payment:
35 Seconds = Listen to customer. Enter each food item into the Cash Register Computer.
25 Seconds = Receive payment from customer and return change (or scan credit card)
5 Seconds = Step to Soft Drink Cup area. Select the proper size Soft Drink Cup. Step to Front Counter.
Hand the empty cup to the customer.
Prepare To-Go Paper Bag and Add Food Items at the Food Area:
5 Seconds = Walk to Order Filling Work Area.
15 Seconds = Open a To-Go Paper Bag.
10 Seconds = Tear the Printed Order off the Printer. Tape it to the Bag.
5 Seconds = Carefully read the Printed Order. Memorize the food items to put into the Bag.
5 Seconds = Wait for the Cook to put a Cheeseburger in the Sandwich Storage Chute.
10 Seconds = Place one Cheeseburger into the To-Go Bag.
5 Seconds = Move to French Fry Staging Area with To-Go Bag.
20 Seconds = Fill one French Fry Paper Bag with French Fries. Place Fries in the To-Go Bag.
5 Seconds = Place one Napkin in the To-Go Bag.
Fill the To-Go Paper Bag at the Counter and Give the Bag to the Customer:
5 Seconds = Walk to Front Counter.
10 Seconds = Place two Ketchup Packets from under the Front Counter into the Bag.
5 Seconds = Give the completed To-Go Bag to the customer.
5 Seconds = Return to the Cash Register to get ready for the next customer.

Process Chart Symbols
There are a variety of process charts used in methods analysis, such as:
1. An Operation Process Chart: Shows the operations and the inspections that are required to
complete a specific process or activity, in the sequence in which they occur.
2. A Flow Process Chart: Shows the operations, inspections, transportations, delays, and
storages that are required to complete a specific process or activity, in the sequence in which
they occur.
3. A Flow Diagram: Illustrates the flow process chart activities on a sketch of the work area.
4. A Left-Hand/Right-Hand Chart: Shows the work and idle time of each hand in comparison
to one another.
5. A Multiple Activity Chart: Shows the breakdown on the work done by people and the work
done by machinery in relationship to a time scale.
One thing these different charts have in common is the symbols used on the charts and the
definitions of those symbols.
There are five basic symbols as follows:
Operation:
1. An operation is represented with a circle or the capital letter “O.”
2. The operation symbol is used to represent a person doing work.
3. An operation occurs when an object is intentionally altered in any of its physical or
chemical characteristics.
4. It may be assembled or disassembled from another object, or it may be prepared for another
operation, transportation, inspection, or storage.
5. An operation also occurs when information is given or received, or when planning or
calculating takes place.
Inspection:
1. An inspection is represented with a diamond or the capital letter “I.”
2. An inspection represents a person who is examining an object and comparing it to a
standard.
3. An inspection occurs when an object is examined for identification or is verified for quality
or quantity in any of its characteristics.
4. Objects, data, or information can be inspected.
Transportation:
1. A transportation is represented with an arrow or the capital letter “T.”
2. A transportation occurs when an object is moved from one place to another.
3. Objects, data, and information can be transported.
4. When the movement occurs as a normal part of an operation or inspection, the action is not
considered to be a transportation.
Delay:
1. A delay is represented with a capital letter “D.”
2. A delay occurs when an object is temporarily set aside.
3. The object still requires additional processing, but that processing can not take place at the
current time.
4. When the circumstances that caused the delay are resolved, the object will then receive the
processing originally scheduled for it.
5. The amount of time for a delay is relatively short, such as seconds, minutes, hours, or
sometimes days.
Storage:
1. A storage is represented with a triangle or a capital letter “S.”
2. A storage occurs when an object is intentionally set aside for the purpose of removing it
from the mainstream of activities.
3. The purpose of the storage is to protect the product during its period of inactivity, and to
prevent its unauthorized use or removal.
4. The amount of time for storage is relatively long, such as days, weeks, months, or
sometimes years.
Combined Activity:
1. When two or more activities are performed simultaneously or by the same employee, then
the symbols for those activities are combined.
2. The most common example of a combined activity occurs when an employee performs an
operation on an object, and then immediately inspects the object to verify the quality of their
own work. The symbol for this combined activity would be a circle inside a diamond or the
capital letters “OI.”
How to Create an Operation Process Chart
An Operation Process Chart is a graphic, symbolic representation of the act of producing a
product or providing a service. Its primary focus is on the Operations and Inspections
necessary to do the work.
The rules for constructing an Operation Process Chart are as follows:
1. At the top of the page, insert the Analyst’s Name, the Date, and the Name of the Operation
being studied.
2. At the top of the page, include all the other additional information, such as the total number
of operations and inspections.
3. If a product is being studied, a simple sketch of the product should be drawn near the top of
the page below the summary information.
4. Only Operations and Inspections are shown on the chart.
5. Operations are represented with a Circle.
6. Inspections are represented with a Diamond.
7. If an Inspection is done at the same time as an Operation, then a Circle is drawn inside a
Diamond to represent the combined activity.
8. If the Operations and Inspections are numbered, then the number should be written inside
the Circle or Diamond.
9. The sequence of activities should be from the top to the bottom of the page in the order in
which they are done.
10. If there are two or more assembly lines that gradually merge, then they should be shown
side-by-side on the chart as they are actually done.
11. The symbols should be connected with straight lines to show the correct sequence of
activities.
12. If materials enter the process at an operation, then the material should be written above a
horizontal line that enters the process from the left. The horizontal line may be above the
Operation and then connected to the top of the circle, or the horizontal line may be drawn on
the left side of the circle and attached to the right side of the circle.
13. If multiple materials enter a process at the same activity, each material must be listed on a
separate horizontal line and the line attached to the circle where the material enters the
process.
14. A brief description of each activity must be written on the right side of the symbol.
15. Occasionally, time, frequency, and/or location may also be included.
Microsoft WORD Documents that correspond to this Module Assignment.
The Module 01 WORD documents are in Module One Learning Module Folder.
Instructions for the HW1 Module One Homework Assignment
Operation Process Chart
Download the Three Cook Examples. These are completed forms and they illustrate exactly
how an Operation Process Chart is constructed based on a description of the work performed
by a Cook.
Download the Module 1 Assignment. This document contains information on the food item
that will be prepared by the Cashier at the Fast Food Restaurant called Mexican BurgerMac,
Inc. and it contains a description of the work done by the Cashier.
Also download the Cashier Work Area so you can see where this food order is prepared
inside the restaurant. The kitchen work area layout will help you to better visualize how the
food item is prepared. You do not need to do anything to the kitchen work area layout for this
Module Assignment.
When the Cashier is standing in her normal position in front of the Front Counter, she receives
the order from a walk-in customer and enters the order on the computer on top of the Front
Counter. She then either receives cash and makes change or she scans the customer’s credit
card for payment. The soft drink cup dispenser is about one foot behind from the Front
Counter. The Order Filling area is approximately three feet behind the Front Counter. It takes
the Cashier 5 seconds to walk to any location inside the Front Counter area regardless of how
far away it is from where she might be at the time she starts walking.
Download the Cashier Operation Process Chart template.
You are to complete the Operation Process Chart Form for the Food Item specified. You are to
create the chart from the perspective of a Cashier who prepares the food order.
Your entire chart should fit on the Operation Process Chart Form that you downloaded.
However, if you need more space then add a blank page to the original WORD document file.
You must complete the Operation Process Chart using Microsoft WORD.
Only Operations (circles) and Inspections (diamonds) are shown on an Operation Process
Chart. Be sure to follow all the rules for constructing an Operation Process Chart as explained
in the lecture that accompanies this Module Assignment.
There are some Operation and Inspection templates on the form. You may copy and paste
them as often as you need them. Change the number inside the symbol, write a short work
description beside the symbol, and if a material is being introduced into the process for the
first time, then describe the material on the horizontal line. Only describe each material one
time even though it may continue through the entire process from the beginning to the end.
Every material must be shown on the chart at the point where if first enters the process.
Do not include walking, cooking, or waiting activities on the Operation Process Chart. Do not
change these other activities into operations and then add them to the Operation Process Chart.
