1. Introduction

1.1 Purpose

First Class Airlines (FCA) was founded in 1999 and provides flights to an elusive clientele of elite corporate executives and government employees. They are known for their very high level of service with all of the conveniences of the office to ensure that transportation from one city to another is not a disruption to their clientele’s workload. To book a flight with FCA, one must call into the FCA central office to reserve a flight and make any special requests. A service that was once a little known secret in the corporate world is beginning to grow. As a result, FCA is struggling to keep up with the demand for their service. To combat this struggle, FCA purchased 50 additional passenger planes and hired of 300 new employees; however, customers are still frustrated by the long wait times experienced when scheduling flights by phone. As a result, FCA has hired Lewis Consulting to create and implement an Airline Reservation System (ARS) that will be accessible as an application for the Samsung Galaxy S6 smartphone.

This Software Requirements Specification (SRS) outlines the steps taken to create a working solution for the initial deployment of the FCA reservation system. The role of Lewis Consulting will be to design and implement an ARS that can be used by passengers and potential passengers as a self-service tool. Phase 1 of the FCA Reservation System will allow passengers to establish a secure connection to the FCA Reservation System, log in, search for available flights, create a reservation, cancel a reservation, and view a listing of all reservations.

1.2 Document Conventions

Main topics are bolded in a heading and are represented using whole numbers. Sub topics and bullets are indented beneath the main topic heading with a decimal version

of the whole number. All acronyms will be introduced with its full name, followed by its acronym in parenthesis.

From this point forward, the acronym is used in place of the full word titles. In the glossary in Appendix A, any acronyms used within this document are outlined in

alphabetical order for easy reference.

1.3 Intended Audience and Reading Suggestions

This document is written by Lewis Consulting in response to FCA’s request for a proposal for the first phase of the ARS. It is intended for use by all who are involved in the design of the FCA Reservation System. This includes all stakeholders and employees of FCA, in addition to designers, developers, testers, programmers, testers, and programmers of Lewis Consulting Services. This document is best read from beginning to end to fully grasp the program to be implemented, however the table of contents can be used to hone in on specific areas of interest to specific readers. By using the CTRL key and clicking on any item in the Table of Contents, readers can jump straight to topics of interest.

This document is not intended for use by end-users. Documentation provided for use of the software by end users should be created by FCA after the completion of this application.


1.4 Project Scope

In the first phase of FCA Reservation System, the following functions will be included:

Establish a secure connection Login to the system Search for available flights Create reservation View reservation Cancel reservation

The ARS will be accessible from all the Samsung Galaxy S6 smartphone with the FCA Reservations Application installed. Lewis Consulting will perform one User Acceptance Test (UAT) with FCA representatives.

Training of FCA Reservation System users and managing login credentials is out of the scope of this project and is the responsibility of FCA.

2. Overall Description

2.1 Product Perspective

The FCA Reservation application is a brand new venture for FCA. As a small airline, there are concerns that the application may not compete well with those of larger scoped travel applications, like Travelocity and Expedia. The goal with Phase 1 of the FCA Reservation application is to offer travelers the ability to provide basic flight searching, reservation and cancellation abilities from the Samsung Galaxy S6 smartphone. The desired result is a product that allows flyers to self-serve and avoid long telephone hold times when calling into the FCA Reservation office.


Figure 2.1 – Samsung Galaxy S6 smartphone

2.2Product

Features

The FCA Reservation application allows users of the Samsung Galaxy S6 smartphone to install the application from the Google Play Store and perform a series of actions to aid in the airline reservations process. These functions include securing a secure connection to the FCA Servers, logging into an account, searching for flights, creating a reservation, viewing all reservations, and cancelling a reservation.

Figure 2.2 – UML Data Flow Diagram for FCA Airlines Reservation application

2.3 User Classes and Characteristics

Travelers with a Samsung Galaxy S6 smartphone are the target users of the FCA Reservation application. General characteristics of these users are:

Adults age 18 and older


Owners of a Samsung Galaxy S6 smartphone May or may not be tech savvy May or may not have prior experience with travel applications May or may not be educated and trained

2.4 Operating Environment

FCA has chosen the following elements of the environment for the FCA Reservation application:

The FCA server is the HP ProLiant SL 4500 server with a Citrix OS interface The Samsung Galaxy S6 smartphone with a Linux-based Operating System (OS) will be

used to house the application. The database which holds customers’ data and flight data is SQL.

2.5 Design and Implementation Constraints

The FCA Reservation application will be designed only for the Samsung Galaxy S6 smartphone.

It is the responsibility of the potential traveler to download and install the FCA Reservation application to a Samsung Galaxy S6 smartphone.

It is the responsibility of the potential traveler to maintain the application and keep it updated.

The FCA server is available 24/7, except during scheduled maintenance times. The application will be designed for use on the 1440 x 2560 pixel screen size that comes

standard on the Samsung Galaxy S6 smartphone. Any memory restrictions applied to the Samsung Galaxy S6 smartphone will apply as

design constraints. Interruption of cell phone service will cause the application to close and require the

establishment of a new secure session. Secure sessions will be monitored in order to ensure proper closure after 5 minutes of

inactivity for security purposes.

2.6 User Documentation

The FCA Reservation application will use a very intuitive design, leaving the following considerations:

A Portable Document Format (PDF) User manual will be provided by Lewis Consulting to FCA with an overview of the application and its functionalities.

It will be the responsibility of FCA to provide users of the FCA Reservation application with instruction on use of the application from a users’ standpoint.

User acceptance testing materials will be provided by Lewis Consulting. A question mark icon will appear in the upper right corner of the application at all times.

When a user clicks on this icon, a help center article provided by FCA will open in an external browser to provide users with additional instruction.

2.7 Assumptions and Dependencies

The application will be used only by confirmed passengers and potential passengers of FCA.

Users own or have access to a Samsung Galaxy S6 smartphone.


Users of the application are knowledgeable about using applications on their Samsung Galaxy S6 smartphone.

Users will keep the FCA Reservation application and smartphone updated It is the responsibility of FCA to keep the application updated with the most current

technology The servers at FCA are up and running.

3. System FeaturesThis section outlines the low level details of each system function of the FCA Reservation System. It sets priorities of each function so that developers and FCA stakeholders know what will be accomplished first and what functions will be available for review first.

3.1 Secure Session

3.1.1 Description and PriorityBecause sensitive information and personal data is exchanged between passengers and

the application, the information contained within each session must remain protected and confidential. FCA is responsible for safeguarding the data transferred by the FCA Reservation System application. It is crucial that the FCA Reservation System application keep this data encrypted and safeguarded from those with nefarious or malicious intent. This is the highest priority.

3.1.2 Stimulus/Response SequencesThe user opens the FCA Reservation application by touching the application icon on their

Samsung Galaxy S6 smartphone. This launches the application interface and automatically begins securing a connection to the FCA servers.

3.1.3 Functional Requirements

SS-1: a secure session is established between the FCA Reservation application and the FCA servers

SS-2: an icon displays to let the user know that a secure connection has been successfully attained prior to continuing to the rest of the application

SS-3: if a secure connection could not be established, an error message is displayed and the application closes

SS-4: when the application is closed or when 5 minutes of inactivity elapses, the secure session terminates

3.2 Login

3.2.1 Description and PriorityThe user will be prompted by the FCA Reservation application to enter a username and

password on a login screen. Upon submission of valid login credentials, the data will be verified by the FCA Servers. Verification of the user is important because the Samsung Galaxy S6 smartphone may be lost or accessed by someone other than the authorized user. Because this application includes payment data and other sensitive materials, ensuring that only authorized users can access this data is crucial. Passengers and FCA is responsible for the protection of login credentials. This feature is of highest priority.


3.2.2 Stimulus/Response SequencesAfter a secure session is established, a login screen will be displayed to the user. The user

will enter a username and password, and then select a button that says, “Login” to submit their credentials to the FCA Servers for validation. The application will display a message indicating the success or failure of the authentication.


LI-1: a login page is displayed and asks the user to enter a username and password.

LI -2: the password will be masked as it is typed into the login interfaceLI -3: a touchable button submits the username and password from the login

form to the FCA ServerLI -4: the credentials are compared against those stored in the FCA databaseLI-5: if login information does not match, the user will be given two more

chances to enter correct login informationLI -6: after 3 failed login attempts, the user account is locked and an error

message is displayed instructing the user to call a 1-800 number to reactivate the account

LI-7: if the database matches the credentials, the server returns the confirmation

LI-8: after confirmation of correct login credentials, the FCA Reservation application menu is displayed

3.2.4 Test Case 1: Failed Login Lockout

Test Name: TC1: Failed Login LockoutDescription: User is locked out after 3 failed password attempts Requirement(s): Spec. 3.2, LI-1 – LI-6 , UC2Prerequisites: The FCA Reservation has been installed on a Samsung

7. Await results An error message informs the user that the username and password do not match, the account is locked, and they must call a 1-800 number to restore account access

3.3 Search for Flights

3.3.1 Description and PriorityUpon successful entry into the FCA Reservation Application, a user can select “Search for

Flights” from the application’s main menu. This allows users to search for available flights. This function is one of the main motivators of the application, but it’s quite as crucial as the establishment of a secure connection or login ability so its feature is of medium priority.

3.3.2 Stimulus/Response SequencesAfter a user selects “Search for Flights” from the FCA Reservation application menu, the

search interface opens. The application accepts an entry of the departure city, arrival city, and travel date from the user and submits this request to the FCA Servers. The FCA Server then returns a listing of available flights that meet the user’s selection. If no flights are available, the user will be provided with a listing of similar flights that depart or arrive at airports near to the desired destination.



SF-1: a search form will be provided to the user that requests the city of departure, city of arrival, and travel dates

SF-2: a touchable button submits the dataSF-3: data is validated for completeness, accurate dates, and valid cities of

departure and arrivalSF-4: if the data is complete and valid, the FCA Reservation application will

request matching flights from the FCA databaseSF-5: if matching flights exist, the FCA Reservation application will display

matching flights to the userSF-6: if no matching flights exist, an error will be displayed and nearby cities of

departure/arrival will be presented to the user

3.3.4 Test Case 2: Search for Flights

Test Name: TC2: Search for FlightsDescription: Display flight listingRequirement(s): Spec. 3.3, SF-1 – SF-5, UC3Prerequisites: The FCA Reservation has been installed on a Samsung

Galaxy S6 smartphone. The tester has valid login credentials. Flights must exist in the database that match the criteria that the tester will be entering.

Setup: The tester will begin by opening the FCA Reservation application on a Samsung Galaxy S6 smartphone. The application interface will indicate through imagery that a secure session has been established with the server. The user will log into the application with valid login credentials, and then select “Search for Flights” from the application’s main menu.

TC2: Search for Flights


Pass/Fail

Severity

1. Await search form The application displays a search form. This form provides prompts to enter a departure city and arrival city into separate text boxes and a submit button to submit search query.

2. Enter a valid city of departure, city of arrival, and travel date, then press Submit

A loading symbol appears. The application sends the search query to the FCA server/database.




Pass/Fail

Severity

3. Await results A loading symbol appears. The FCA application accepts a listing of matching flights from the FCA server/database and prepares for display.

4. Observe that the list of matching flights have been returned

The FCA application displays a listing of flights that match the selected city of departure, city of arrival, and travel date.

3.4 Create New Reservation

3.4.1 Description and PriorityAfter selecting an available flight, users can create a reservation for a flight. Users will then

submit their personal data to secure their seat for the flight. Because this function is a main motivation for the creation of the FCA Reservation Application, but is not as crucial as the establishment of a secure session or login, its priority is medium.

3.4.2 Stimulus/Response SequencesAfter an available flight is selected, the FCA Reservation application displays a reservation

form. Upon submission, the FCA Reservation application submits the payment details to the Pay Processor and all other fields to the FCA Database. For entries with successful payment, a reservation will be created and confirmation will be provided to the user. For payment failures, a reservation will not be created and an error message will be displayed to the user.


CNR-1: display a reservation form to users to enter their name, email address, and billing information

CNR -2: a touchable button submits the dataCNR -3: data is validated for completenessCNR -4: if data is missing, an error message is displayedCNR -5: if data is complete, the FCA Reservation application will submit the user’s

name and email address to the FCA Database for storage upon selection of the submit button

CNR -6: if data is complete, the FCA Reservation Application will submit payment information to the Pay Processor for processing upon selection of the submit button

CNR -7: the FCA Reservation Application will display a success or failure message provided by the Pay Processor

CNR -8: if the payment is successful, a confirmation message will display on-screen and be sent to the email address provided by the user

CNR -9: if the payment is not successful, an error will display and up to two additional attempts will be permitted

CNR-10: after three failed payment attempts the user will be prompted to call a 1-800 number to complete their reservation


3.5 View Reservation

3.5.1 Description and PriorityUsers who have previously made a reservation can view their reservation details by

selecting “View Reservations” from the FCA Reservation application main menu. This functionality is not core to the vision of the application as a whole so its priority is low.

3.5.2 Stimulus/Response SequencesWhen a user selects “View Reservations” from the FCA Reservations application, the FCA

Reservation application will make a request to the FCA database for any flights on which the user has a confirmed reservation. In cases where a user has multiple confirmed reservations, an index page will first appear to allow the user to select which flight in which to view the details. For flights departing more than 72 hours in the future, an option to cancel the reservation will be provided.


VR-1: the FCA Reservation application will request a listing of reserved flights for the user from the FCA Database

VR-2: if no reserved flights exist, an error message will displayVR-3: if reserved flights exist, a listing of confirmed reservations will displayVR-4: when selected, a detailed view of the flight details will displayVR-5: for flights departing more than 72 hours in the future, an option to cancel

the flight will be provided within the flight details

3.5.4 Test Case 3: View Reservations

Test Name: TC3: View ReservationDescription: Display reservation detailsRequirement(s): Spec. 3.5, VR-1, VR-3, UC5Prerequisites: The FCA Reservation has been installed on a Samsung

Galaxy S6 smartphone. The tester has valid login credentials. The tester has previously secured a reservation and the reservation exists in the FCA database.

Setup: The tester will begin by opening the FCA Reservation application on a Samsung Galaxy S6 smartphone. The application interface will indicate through imagery that a secure session has been established with the server. The user will log into the application with valid login credentials, and then select “View Flights” from the application’s main menu.

TC3: View Reservation




Pass/Fail

Severity

1. Await flight listing A loading symbol appears. The application sends a request to the FCA server/database for a listing of confirmed flight reservations for the current user.

2. Await flight listing The application accepts a listing of confirmed flight reservations from the FCA server/database and displays this information to the user.

3. Select individual entry to display.

A loading symbol appears. The application resends a request to the FCA server/database for the individual reservation details.

4. Await results The FCA application accepts the reservation details from the FCA server/database and displays this information to the user.

3.6 Cancel Reservation

3.6.1 Description and PriorityUsers who have previously made a reservation can cancel a reservation for flights

scheduled to depart more than 72 hours in the future. This functionality is not core to the vision of the application as a whole so its priority is low.

3.6.2 Stimulus/Response SequencesA user who has a confirmed reservation selects “Cancel Flight”. For flights scheduled to

depart within 72 hours, the user is given an error message instructing him or her to call FCA to cancel their flight. For flights scheduled to depart more than 72 hours in the future, the FCA Reservation application instructs the Pay Processor to refund the reservation fee and instructs the FCA database to update the reservation from a status of RESERVED to a status of CANCELLED. An on-screen notification and email notification are provided to the user upon successful cancellation of the reservation.


CR-1: the FCA Reservation application will prompt the user to confirm that they would like to cancel the reservation before taking action.

CR-2: for flights scheduled to depart within the next 72 hours, an error message will display to prompt the user to call a 1-800 number to cancel

CR-3: for flights scheduled to depart 72 hours or more in the future, the FCA Reservation application will instruct the Pay Processor to issue a refund of the reservation fee


CR-4: for flights scheduled to depart 72 hours or more in the future, the FCA Reservation application will update the reservation status for the user from RESERVED to CANCELLED

CR-5: an on-screen confirmation of refund and cancellation will be provided to the user


4. External Interface Requirements

6.1 What is Agile Development Methodology

Agile Software Development Methodology is a modern style of software development that places a strong emphasis on customer satisfaction through a continuous delivery of functional software. This methodology is a culmination of a number of positive aspects of methodologies in use in the 1990’s and formally became recognized as a software methodology in 2001. There are 12 principles that form the basis of Agile Development. They are:

Customer Satisfaction through continuous delivery of software. Openness to changing requirements, even late in development. Deliverance of working software with a preference to shorter timescales. Collaboration between business people and developers. Building projects around motivated individuals, providing the environment and support to

get the job done. Efficiency in conveying information to and within a development team through face-to-face

conversation. Use of working software as the primary measure of progress. Promotion of sustainable development. Continuous attention to technical excellence and good design. Maximizing the amount of work done through simplicity. Use of self –organized teams to provide the best architectures, designs, and

requirements.


Regular reflection on effectiveness, fine tuning, and adjustment.
