User Manual - RED AI
Chapter 1. Welcome
Thank you for choosing to test the Restaurant Efficiency Decision Artificial Intelligence
(RED AI) prototype software suite with customizable expert decision-making algorithms that
help monitor, manage, and improve your business. RED AI allows you to record data
concerning your restaurant’s key profit factors and offers a continuous restaurant efficiency
consultant services all in one convenient location: the computer in your office. This manual has
been provided to help you get started using the RED AI productivity software. For frequently
asked questions and troubleshooting advice, refer to the Help System.
Section 1.
What is in the box?
The RED AI distribution includes a RED AI User Manual, which you are reading right
now, and a RED AI Installation Disc. The User Manual is written for the novice computer user,
and can be used as a systematic guide for first-time users. When installed, the RED AI software
will consist of three main
modules: the graphical user
interface (GUI), the restaurant
model database (DB), and the
Efficiency Engine with expert
rule-sets. The relationship
between each of these elements is
shown in Figure 1.

User Manual - RED AI
Section 2.
Why is it here?
The restaurant business is a tough place with low profit margins. Consider what it takes
to be successful in this industry: an owner or manager has to keep track of his or her staff, both
in front and back, inventory, customer flow, all while striving to maintain an inviting
atmosphere. Currently, there are many products available, which focus on the collection and
organization of data regarding each of these elements separately. In addition to all the work
required to record this data, the wise manager or owner will invest a considerable amount of time
in its analysis. A well-managed restaurant averages about 4% net profit, provided it is able to
avoid the typical fate of young restaurants: going out of business within the first three years of
operation.
Obviously, something is missing. Our product seeks to correct this. There is no doubt
managers and owners benefit from well-organized representations of their restaurant’s statistics.
Indeed, the ideal solution might be a system designed to collaborate as much of this data as
possible; further, the ability to identify problem trends with the purpose of highlighting them for
presentation to the owners and managers would increase a given restaurant’s efficiency. In the
event there existed a product incorporating all these features, with the added capability of
providing thoroughly tested suggestions for efficiency maximization, that product would soon
become a restaurant manager’s essential sidekick. To this end, we have taken it upon ourselves
to create a top-notch Restaurant Efficiency Decision Artificial Intelligence, RED AI.
This user manual and the included software will provide a preview of things to come.
RED AI, the official RED AI product prototype, has been designed to offer a scaled-down
sample of the innovation coming with the release of RED AI. Truly, this prototype marks the
beginning of change.

Section 3.
What does it do?
Monitor
The RED AI software provides the ideal means for keeping track of your restaurant’s key
profit factor data. Front-end employees can enter summary order data and customer service data.
Back-end employees can update the inventory as necessary and managers can record the number
and type of staff on shift at a given time. With RED AI, this data can be kept on hand for as long
as you own your restaurant!
Manage
Using the editing features provided by RED AI and the translation rules, managers and
owners can stay informed. Edit screens provide the ability to view customer, staff, inventory,
and menu data directly. Restaurant data is fully searchable and editable. At any time, the
database can be backed-up to ensure data safety. Translation rules, applied in the efficiency
engine, are designed to perceive complex relations between restaurant profit factors and
highlight trends that might otherwise be overlooked.
Improve
The number one goal of the RED AI Team is to help restaurant owners achieve greater
success in their business. The RED AI efficiency engine included in RED AI will analyze
restaurant data and identify cases of suboptimal restaurant functioning. The analyses will isolate
these instances of inefficient restaurant operation and offer clear, plain English, suggestions for
correcting the underlying flaw in staffing, menu pricing, or inventory management that gave rise
to the inefficient scenario.
