This appendix illustrates some of the requirements documents and diagrams described in this book, using a hypothetical project called the Cafeteria Ordering System (COS). This appendix includes:
A vision and scope document.
A list of use cases and several use case specifications, showing different degrees of detail.
A portion of a software requirements specification.
Several partial analysis models, including a feature tree, context diagram, entity-relationship diagram, and state-transition diagram.
A partial data dictionary.
Several business rules.
Because this is just an example, these deliverables aren’t intended to be complete. Instead, they are meant to illustrate how the various types of requirements information relate to each other and how you might write the contents of each document section. The information in these examples could be organized and grouped in many other reasonable ways, including combining it into a single document on a small project or storing it in a requirements management tool. Clarity, completeness, and usability of the requirements information are the essential objectives. The examples conform to the templates described in previous chapters. Because this is a small project, some template sections have been combined. Every project should consider how to adapt the organization’s standard templates to best suit the size and nature of the project.
Employees at the company Process Impact presently spend an average of 65 minutes per day going to the cafeteria to select, purchase, and eat lunch. About 20 minutes of this time is spent walking to and from the cafeteria, selecting their meals, and paying by cash or credit card. When employees go out for lunch, they spend an average of 90 minutes off-site. Some employees phone the cafeteria in advance to order a meal to be ready for them to pick up. Employees don’t always get the selections they want because the cafeteria runs out of certain items. The cafeteria wastes a significant quantity of food that is not purchased and must be thrown away. These same issues apply to breakfast and supper, although far fewer employees use the cafeteria for those meals than for lunch.
Many employees have requested a system that would permit a cafeteria user to order meals (defined as a set of one or more food items selected from the cafeteria menu) online, to be picked up at the cafeteria or delivered to a company location at a specified time and date. Such a system would save employees time, and it would increase their chance of getting the items they prefer. Knowing what food items customers want in advance would reduce waste in the cafeteria and would improve the efficiency of cafeteria staff. The future ability for employees to order meals for delivery from local restaurants would make a wide range of choices available to employees and provide the possibility of cost savings through volume discount agreements with the restaurants.
BO-1: Reduce the cost of cafeteria food wastage by 40% within 6 months following initial release. [This example shows the use of Planguage to precisely state a business objective.]
Scale: Cost of food thrown away each week by cafeteria staff
Meter: Examination of Cafeteria Inventory System logs
Past: 33% (2013, initial study)
Goal: Less than 20%
Stretch: Less than 15%
BO-2: Reduce cafeteria operating costs by 15% within 12 months following initial release.
BO-3: Increase average effective work time by 15 minutes per cafeteria-using employee per day within 6 months following initial release.
SM-1: 75% of employees who used the cafeteria at least 3 times per week during Q3 2013 use the COS at least once a week within 6 months following initial release.
SM-2: The average rating on the quarterly cafeteria satisfaction survey increases by 0.5 on a scale of 1 to 6 from the Q3 2013 rating within 3 months following initial release and by 1.0 within 12 months.
For employees who want to order meals from the company cafeteria or from local restaurants online, the Cafeteria Ordering System is an Internet-based and smartphone-enabled application that will accept individual or group meal orders, process payments, and trigger delivery of the prepared meals to a designated location on the Process Impact campus. Unlike the current telephone and manual ordering processes, employees who use the Cafeteria Ordering System will not have to go to the cafeteria to get their meals, which will save them time and will increase the food choices available to them.
RI-1: The Cafeteria Employees Union might require that their contract be renegotiated to reflect the new employee roles and cafeteria hours of operation. (Probability = 0.6; Impact = 3)
RI-2: Too few employees might use the system, reducing the return on investment from the system development and the changes in cafeteria operating procedures. (Probability = 0.3; Impact = 9)
RI-3: Local restaurants might not agree to offer delivery, which would reduce employee satisfaction with the system and possibly their usage of it. (Probability = 0.3; Impact = 3)
RI-4: Sufficient delivery capacity might not be available, which means that employees might not always receive their meals on time and could not always request delivery for the desired times. (Probability = 0.5; Impact = 6)
AS-1: Systems with appropriate user interfaces will be available for cafeteria employees to process the expected volume of meals ordered.
AS-2: Cafeteria staff and vehicles will be available to deliver all meals for specified delivery time slots within 15 minutes of the requested delivery time.
DE-1: If a restaurant has its own online ordering system, the Cafeteria Ordering System must be able to communicate with it bidirectionally.
FE-1: Order and pay for meals from the cafeteria menu to be picked up or delivered.
FE-2: Order and pay for meals from local restaurants to be delivered.
FE-3: Create, view, modify, and cancel meal subscriptions for standing or recurring meal orders, or for daily special meals.
FE-4: Create, view, modify, delete, and archive cafeteria menus.
FE-5: View ingredient lists and nutritional information for cafeteria menu items.
FE-6: Provide system access through corporate intranet, smartphone, tablet, and outside Internet access by authorized employees.

| ||
Alternative Flows: | 1.1 Order multiple identical meals
1.2 Order multiple meals
| ||
Exceptions: | 1.0.E1 Requested date is today and current time is after today’s order cutoff time 1. COS informs Patron that it’s too late to place an order for today. 2a. If Patron cancels the meal ordering process, then COS terminates use case. 2b. Else if Patron requests another date, then COS restarts use case. 1.0.E2 No delivery times left 1. COS informs Patron that no delivery times are available for the meal date. 2a. If Patron cancels the meal ordering process, then COS terminates use case. 2b. Else if Patron requests to pick the order up at the cafeteria, then continue with normal flow, but skip steps 7 and 8. 1.1.E1 Insufficient inventory to fulfill multiple meal order 1. COS informs Patron of the maximum number of identical meals he can order, based on current available inventory. 2a. If Patron modifies number of meals ordered, then return to step 4 of normal flow. 2b. Else if Patron cancels the meal ordering process, then COS terminates use case. | ||
Priority: | High | ||
Frequency of Use: | Approximately 300 users, average of one usage per day. Peak usage load for this use case is between 9:00 A.M. and 10:00 A.M. local time. | ||
Business Rules: | BR-1, BR-2, BR-3, BR-4, BR-11, BR-12, BR-33 | ||
Other Information: |
| ||
Assumptions: | Assume that 15 percent of Patrons will order the daily special (Source: previous 6 months of cafeteria data). |
[Note: the following use case is written in less detail than UC-1, to illustrate that it isn’t always necessary to fully specify every detail of the use case, provided developers have the necessary information available from some other source.]
ID and Name: | UC-5 Register for Payroll Deduction | ||
Created By: | Nancy Anderson | Date Created: | September 15, 2013 |
Primary Actor: | Patron | Secondary Actors: | Payroll System |
Description: | Cafeteria patrons who use the COS and have meals delivered must be registered for payroll deduction. For noncash purchases made through the COS, the cafeteria will issue a payment request to the Payroll System, which will deduct the meal costs from the next scheduled employee payday direct deposit. | ||
Trigger: | Patron requests to register for payroll deduction, or Patron says yes when COS asks if he wants to register. | ||
Preconditions: | PRE-1. Patron is logged into COS. | ||
Postconditions: | POST-1. Patron is registered for payroll deduction. | ||
Normal Flow: | 5.0 Register for Payroll Deduction
| ||
Alternative Flows: | None | ||
Exceptions: | 5.0.E1 Patron is not eligible for payroll deduction. 5.0.E2 Patron is already enrolled for payroll deduction. | ||
Priority: | High | ||
Business Rules: | BR-86 and BR-88 govern an employee’s eligibility to enroll for payroll deduction. | ||
Other Information: | Expect high frequency of executing this use case within first 2 weeks after system is released. |
[Note: the following use case is written in a very brief form, to illustrate that it is not always necessary to fully complete the use case template, provided developers have the necessary information available from some other source. It’s a good idea to plan out which use cases require detailing and which do not.]
ID and Name: | UC-9 Modify a Menu | ||
Created By: | Mark Hassall | Date Created: | October 7, 2013 |
Description: | The cafeteria Menu Manager may retrieve the menu for a specific date in the future, modify it to add new food items, remove or change food items, create or change a meal special, or change prices, and save the modified menu. | ||
Exceptions: | No menu exists for the specified date; show an error message and let the Menu Manager enter a new date. | ||
Priority: | High | ||
Business Rules: | BR-24 | ||
Other Information: | Certain food items will not be deliverable, so the menu presented to the Patrons of the COS for delivery will not always exactly match the menu available for pickup in the cafeteria. The Menu Manager can set which items are not deliverable. |
This SRS describes the functional and nonfunctional requirements for software release 1.0 of the Cafeteria Ordering System (COS). This document is intended to be used by the members of the project team who will implement and verify the correct functioning of the system. Unless otherwise noted, all requirements specified here are committed for release 1.0.
No special typographical conventions are used in this SRS.
The COS will permit Process Impact employees to order meals from the company cafeteria online to be delivered to specified campus locations. A detailed description is available in the Cafeteria Ordering System Vision and Scope Document [1], along with the features that are scheduled for full or partial implementation in this release.

Rath, Andrew. Process Impact Internet Application User Interface Standard, Version 2.0, www.processimpact.com/corporate/standards/PI Internet UI Standard.pdf
The Cafeteria Ordering System is a new software system that replaces the current manual and telephone processes for ordering and picking up meals in the Process Impact cafeteria. The context diagram in Figure D-2 illustrates the external entities and system interfaces for release 1.0. The system is expected to evolve over several releases, ultimately connecting to the Internet ordering services for several local restaurants and to credit and debit card authorization services.
User class | Description |
Patron (favored) | A Patron is a Process Impact employee who wants to order meals to be delivered from the company cafeteria. There are about 600 potential Patrons, of which 300 are expected to use the COS an average of 5 times per week each. Patrons will sometimes order multiple meals for group events or guests. An estimated 60 percent of orders will be placed using the corporate intranet, with 40 percent of orders being placed from home or by smartphone or tablet apps. |
Cafeteria Staff | The Process Impact cafeteria employs about 20 Cafeteria Staff who will receive orders from the COS, prepare meals, package them for delivery, and request delivery. Most of the Cafeteria Staff will need training in the use of the hardware and software for the COS. |
Menu Manager | The Menu Manager is a cafeteria employee who establishes and maintains daily menus of the food items available from the cafeteria. Some menu items may not be available for delivery. The Menu Manager will also define the cafeteria’s daily specials. The Menu Manager will need to edit existing menus periodically. |
Meal Deliverer | As the Cafeteria Staff prepare orders for delivery, they will issue delivery requests to a Meal Deliverer’s smartphone. The Meal Deliverer will pick up the food and deliver it to the Patron. A Meal Deliverer’s other interactions with the COS will be to confirm that a meal was (or was not) delivered. |
OE-1: The COS shall operate correctly with the following web browsers: Windows Internet Explorer versions 7, 8, and 9; Firefox versions 12 through 26; Google Chrome (all versions); and Apple Safari versions 4.0 through 8.0.
OE-2: The COS shall operate on a server running the current corporate-approved versions of Red Hat Linux and Apache HTTP Server.
OE-3: The COS shall permit user access from the corporate intranet; from a VPN Internet connection; and by Android, iOS, and Windows smartphones and tablets.
CO-1: The system’s design, code, and maintenance documentation shall conform to the Process Impact Intranet Development Standard, Version 1.3 [2].
CO-2: The system shall use the current corporate standard Oracle database engine.
CO-3: All HTML code shall conform to the HTML 5.0 standard.
AS-1: The cafeteria is open for breakfast, lunch, and supper every company business day in which employees are expected to be on site.
DE-1: The operation of the COS depends on changes being made in the Payroll System to accept payment requests for meals ordered with the COS.
DE-2: The operation of the COS depends on changes being made in the Cafeteria Inventory System to update the availability of food items as COS accepts meal orders.
A cafeteria Patron whose identity has been verified can order meals either to be delivered to a specified company location or to be picked up in the cafeteria. A Patron can cancel or change a meal order if it has not yet been prepared. Priority = High.
[Details are not provided in this example. Quite a lot of the functionality described under 3.1 Order Meals from Cafeteria could likely be reused, so this section should just specify the additional functionality that addresses the restaurant interface.]
