1 Introduction
Communication is a mean for people to exchange messages. It has started
since the beginning of human creation. Distant communication began as
early as 1800 century with the introduction of television, telegraph and then
telephony. Interestingly enough, telephone communication stands out as the
fastest growing technology, from ﬁxed line to mobile wireless, from voice call
to data transfer. The emergence of computer network and telecommunication
technologies bears the same objective that is to allow people to communicate.
All this while, much eﬀorts has been drawn towards consolidating the device
into one and therefore indiscriminate the services. Chatting is a method of
using technology to bring people and ideas together despite of the geograph-
ical barriers. The technology has been available for years but the acceptance
it was quit recent. Our project is an example of a chat server. It is made
up of applications the client application which runs on the users mobile and
server application which runs on any pc on the network. To start chatting our
client should get connected to server where they can do Group and private
chatting.
1.1 Problem Statement
This project is to create a chat application with a server and users to enable
the users to chat with each others.
To develop an instant messaging solution to enable users to seamlessly com-
municate with each other.
The project should be very easy to use enabling even a novice person to use
it.
1.2 Project Scheduling
This document provides a scalable scheduling tool and associated schedule
development, analysis, and monitoring methods that can be used by Imple-
menting Agencies (IA) to prepare, monitor, and report project schedules.
Our Project is not that complex so we will not use very complex scheduling
method.

communicate with each other.
2. The project should be very easy to use enabling even a novice person
to use it.
2.1 Project Scope & Features
1. Broadcasting Chat Server Application is going to be a text communi-
cation software, it will be able to communicate between two computers
using point to point communication.
7

2. The limitation of Live Chat is it does not support audio conversations.
To overcome this limitation we are concurrently working on developing
better technologies.
3. Companies would like to have a communication software wherein they
can communicate instantly within their organization.
4. The fact that the software uses an internal network setup within the
organization makes it very secure from outside attacks.
2.2 PROJECT SUMMARY
2.2.1 Project Background
The previous work of this already exists. The similar application can be
found on the project either Android market. This project will focus on pro-
viding high quality usability experiences to users mainly following Googles
user interface guideline. Experiments The application will be tested on a test
group to improve the usability quality based on the user’s feedback.
2.3 Functional and Non Functional Requirements
1. User Registration
User must be able to register for the application through a valid phone
number. On installing the application, user must be prompted to reg-
ister their phone number. If user skips this step, application should
close. The users phone number will be the unique identiﬁer of his/her
account on Chat Application.
2. Adding New Contacts
The application should detect all contacts from the users phone book.
If any of the contacts have user accounts with Chat Application, those
contacts must automatically be added to the users contact list on Chat
8

Application. If any of the contacts have not yet registered on Chat
Application, user should be provided with an invite option that sends
those contacts a regular text message asking them to join Chat Appli-
cation along with a link to the Chat Application on Google Playstore.
3. Send Message
User should be able to send instant message to any contact on his/her
Chat Application contact list. User should be notiﬁed when message
is successfully delivered to the recipient by displaying a tick sign next
to the message sent.
4. Broadcast Message
User should be able to create groups of contacts. User should be able
to broadcast messages to these groups.
5. Message Status
User must be able to get information on whether the message sent has
been read by the intended recipient. If recipient reads the message, 2
ticks must appear next to the message read.
2.3.2 Non Functional Requirements
1. Privacy
Messages shared between users should be encrypted to maintain pri-
vacy.
2. Robustness
In case users device crashes, a backup of their chat history must be
stored on remote database servers to enable recoverability.
3. Performance
Application must be lightweight and must send messages instantly.

3 Project Risk Management
3.1 Identification
Risk identification involves determining which risks or threats are likely to
affect the project. It involves the identification of risks or threats that may
lead to project outputs being delayed or reduced, outlays being advanced
or increased and/or output quality (fitness for purpose) being reduced or
compromised. For most large/complex projects, a number of high level risks
should have been identified during the project initiation stage these should
be used as the basis for a more thorough analysis of the risks facing the
project. One of the most difficult things is ensuring that all major risks are
identified. A useful way of identifying relevant risks is defining causal cate-
gories under which risks might be identified. For example, corporate risks,
business risks, project risks and infrastructure risks. These can be broken
down even further into categories such as environmental, economic, politi-
cal, human, etc. Another way is to categorise in terms of risks external to
the project and those that are internal. See the Project Management Risk
Identification Tool for some useful prompts in identifying project risks. The
Australian Standard for Risk Management AS/NZS 4360: 2004 Appendix
D refers to generic sources of risk. The wording or articulation of each risk
should follow a simple two-step approach: 1. Consider what might be a trig-
ger event or threat (eg. poor quality materials causes costs to rise) several
triggers may reveal the same inherent risk; then 2. Identify the risk - use
a newspaper headline style statement short, sharp and snappy (eg. budget
blow out) then describe the nature of the risk and the impact on the project
if the risk is not mitigated or managed (eg. project delayed or abandoned,
expenditure to date wasted, outcomes not realised, government embarrassed
etc). Use the Risk Register (see Appendix A) to document the results. For
large or complex projects it can be beneficial to use an outside facilitator to
conduct a number of meetings or brainstorming sessions involving (as a min-
imum) the Project Manager, Project Team members, Steering Committee
members and external key stakeholders. Preparation may include an envi-
ronmental scan, seeking views of key stakeholders etc. For a small project,
the Project Manager may develop the Risk Register perhaps with input from
the Project Sponsor/Senior Manager and colleagues, or a small group of key
stakeholders. It is very easy to identify a range of risks that are outside the
project and are actually risks to the business area during output delivery,
21

transition or once operational mode has been established. These are not
project risks and should not be included in the Project Risk Register, but
referred to the relevant Business Owner. It may be appropriate to submit
an Issues Paper to the Steering Committee recommending formal acceptance
by the relevant Business Owner for ongoing monitoring and management of
specific risks. See the Project Management Fact Sheet: Developing a Risk
Management Plan and the Risk Identification Tool for more information on
how to undertake risk identification.
In this section specify:
1. Risk identification process that we followed are Brainstorm, facilitated
session, scan by Project Manager etc.
3.2 Analysis and evaluation
After identifying risks we should analyze them by determining how they
might affect the success of your project. Risks should be analyzed and eval-
uated in terms of Probability of occurrence and seriousness of impact if they
do occur. Firstly, assess the likelihood of the risk occurring and give this a
rating of scale from 1-5. The likelihood of harm occurring might be catego-
rized as:
Probability of occurrence
Certain 5 The risk is almost certain to occur (greater than 80% chance)
Likely 4 The risk is more likely to occur than not (between 51% and 80% chance)
Possible 3 The risk is fairly likely to occur ( between 21% and 50% chance)
Unlikely 2 The risk is unlikely but not impossible to occur (between 6% and 20% chance)
Rare 1 The risk is unlikely to occur (less than 5% chance)

List Of Document That Support this document:
1. IEEE 829 Test Plan FORMAT
4.2.3 Introduction
Chat Application will be the interpreter to bring people and ideas together.
We have been designing our Chat Application with well- equipped technology.
This project is now at development phase, so readers can read the Software
Requirement Specification document for details. This document presents the
Master Test Plan of IIT Website. As we know, master test plan is a living
and breathing document that summarizes the overall effort required to test
a software product. Master test plan will actually contain the details of
individual tests to be run during the testing cycle like unit test, system test,
beta test etc. However, our document will categorize and describe each test
case. It will also outline pass-fail criteria and indicate the planned run day or
week. This is a quick-reference tracking document for what has to be tested,
the priority of test items, what is left to test etc. We followed IEEE-829
format to develop our test plan. We strictly follow the instructions provided
by our respective course teacher. This is our first test plan documentation,
so we also read some sample test plan to gather knowledge about test plan
documentation. The estimated time line for this project is a semester. The
testing activities are to be done in parallel with the development process.

4.2.7 Features Not To Be Tested
We will try to test every features. But If we cant manage Schedule. Then
we may skip those Features and attribute with low priority below:
4.2.8 Approach
Testing Levels
The testing approach for Chat Application project is Master Test Plan or
MTP. Which includes unit testing, integration testing and acceptance testing.
In this project testing is done by developer, tester and user. Unit testing will
be done by developers. Developer must provide unit testing data to tester.
Integration testing will be done by tester. After all major and critical de-
fects are solved it will go through acceptance test which will done by end user.
Test Tools
o Selenium Web Browser Automation
o Microsoft Visual Studio 2012 Load Testing
o CIUnit Unit testing for CodeIgniter
o Firebug Web development tool that facilitates debugging
o FreeMind - free mind mapping software
o JSUnit Unit testing for Javascript
o Multi-Mechanize Performance and Load Testing
o Capybara Acceptance test framework
Meetings
The test team will meet once in every weeks to evaluate the progress and
identify all problems and conduct a solution. Test team will also meet with
31

development team to merge their ideas about testing and quality of our web-
site. Addtional mettings can be called as required for emergency situation.
Measures and Metrics
The following information will be collected by the Development team during
the Unit testing process. This information will be provided to the test team
at program turnover as well as be provided to the project team on a biweekly
basis.
o Defects by module and severity
o Defect origin
o Time spent on defect resolution.
The following information will be collected by the test team during all test-
ing phases. This information will be provided on a biweekly basis to the test
manager and to the project team.
o Defects by module and severity
o Defect origin
o Time spent on defect resolution
o Number of times a program submitted to test team as ready for test.
Item Pass Fail Criteria
The test process will be completed when the project leader will be satis-
ﬁed with the result of the test. For this, at least 90% of test cases must pass;
all functionalities must be covered in those test cases and most of all, high
and medium severity defects must be detected and ﬁxed. Minor defects can
be ignored, but with the assurance that it does not lead to severe defect.
The project leader will decide whether the detected defects and criticality
will cause the release of Chat Application of version 1.0 to delay.

5.9 Conclusion
There is always a room for improvements in any apps. Right now we are
just dealing with text communication. There are several android apps which
serve similar purpose as this project, but these apps were rather diﬃcult to
use and provide confusing interfaces. A positive ﬁrst impression is essential
in human relationship as well as in human computer interaction. This project
hopes to develop a chat service Android app with high quality user interface.
In future we may be extended to include features such as:
1. File Transfer
2. Voice Message
3. Video Message
4. Audio Call
5. Video Call
6. Group Call
5.10 Troubleshooting
5.11 Frequently asked question
How do I backup, restore or transfer my Chat Application data?
40

You can back up your ChatApp data using Google Drive or a local backup.
Local backups will be automatically created every day at 2am and they will
be saved as a file in your phone.
Why can’t I connect to Chat App?
Restart your phone, or turn it off and on.
Why are my incoming messages delayed?

How do I reinstall?

Installing ChatApp
Please follow this link. It will navigate you to Google Play where you can
tap Install to start downloading the app.
Open ChatApp and continue to the next screen by agreeing to our Terms of

choose Restore. Learn more about restoring here.
Lastly, type in your name. You can also change this later in ChatApp by
going to Menu Button then Settings, and tapping on your profile name.
How do I fix the Task Manager error?
There are two main problems caused by 3rd party task managers (also called
task killers):
They can temporarily disable ChatApp. This causes ChatApp to disconnect
and reconnect to our server, which drains the battery of your phone and uses
unnecessary amounts of data.
If they close ChatApp, our server has no way of knowing that the connection
has been closed. As a result, message delivery might be delayed.
When I travel abroad, will I be charged for data roaming?
ChatApp Messenger uses the same Internet data plan as web browsing and
email on your phone. If using your cellular data while roaming will nor-
41

mally result in additional charges, you may be charged extra by your mobile
provider for using ChatApp while roaming. Contact your wireless carrier for
details about international roaming countries, SIMs, rates, and policies. If
you do not have an international data plan, we suggest you turn off data
roaming to avoid data roaming charges.
