Executive Summary
Aim of the report is developing the prototype of an application of cab services by using
techniques of User Centred Design in order for identifying the issues with user experience.
After creating the prototype of the application and testing it, the prototype, testing results and
testing process are demonstrated in this report. The stakeholders of cab service are identified
as well as the outcome of the testing goals of the application are observed in this report.

Introduction
Application of cab service is tool of modern day for solving people’s each day
transportation problem. Several issues are there when this comes in travelling from one
location to another one (Chakhlov, et. al., 2016). For solving these issues, cab services are
using application for their users where the users could avoid the issues and book a cab
through the application.
Information Architecture
Stakeholders Identified
Several stakeholders are involved in the cab industry. Total idea of cab services is
noble. However, dominance of the cab over riders started to be prominent. The drivers started
charging the passengers higher amount instead of what was the expectation from them.
Clearly, there was dissatisfaction among the riders and this disrupted cab services. A
stakeholder could be defined as someone who is affected by or engaged in course of action.
Most essential stakeholder for the cab services is customer base (Kell, Marino & Maxted,
2017). The revenue is totally dependent on customer base which is generated by this
business. Second stakeholder of the cab services would be government as government acts as
steward for land where the business dealings would be conducted by such aggregators.
Third stakeholder of cab services would be society as externalities of such startups-
whether negative or positive, would have indelible impact over societal conditions. Fourth
stakeholder of cab services would be existing cab services that don’t depend on the apps for
reaching out customers. It is impossible in mentioning the stakeholders without even talking
about people who invested in cab services, as maximization of the stakeholder wealth is
principle objective for the businesses (Reiman, et. al., 2015). Finally, employees of such

organization are important stakeholders also in such situation. Stakeholders of the cab
services consists of every parties that are involved in progress or survival of the organization.
It includes also all those who are affected by performance, policies and activities of the
organization among others.
Usability Test Documentation
Outcomes of Test Goals
There are several testing levels that help in checking performance and behaviour of
software testing. Such levels of testing are designed for recognizing the missing sections and
reconciliation among development lifecycle states. Every phase of testing go through process
of testing levels of software (León, Karlin & Moody, 2016). There are four levels of testing:
Unit testing, system testing, integration testing and acceptance testing which are done.

Facilitator Script
Facilitator: My name is ______ and I thank you to join me foe the engagement session. I will
share more about why we are here and what are we trying to achieve. Let me discuss about
why the work is happening and what is it we are trying to achieve.
Activity 1:
Facilitator: For the first activity, the prototype of the cab service application is to be
designed.
Activity 2:
Facilitator: For second activity, the sitemap and card sorting of the application is to be
designed.
Activity 3:
Facilitator: For third activity, the stakeholders of the cab service are identified and the
outcomes of the testing of the application should be mentioned.
Facilitator: Thank you again for participating in this work.
User Scenario
User uses the cab services application by registering to the application by using their
contact number or by using their Facebook or Google accounts. After registering to the
application, users could book a cab for comfortable journey. After completion of the journey,
users could make payment by using cash or other online transactions.
Consent forms
You are invited in participating in online survey based on internet. This is a research project
that is conducted by a student. It should take 15 minutes approximately for completion.

Analysis and Discussion of Testing Results
Qualitative Data
Few of the users are really happy using the cab service application. While others feel
that the app could be better for use. Users feel it is easy to login to the application by using
their contact number or by using their Facebook or Google Account. However, users feel that
booking a cab using the app is not good always (Katz, 2015). Functionalities of the app is
easy for some user and others did not have a good experience while using the app.
Quantitative Data
A survey was conducted with 50 users. As per the results of the survey, it is seen that
maximum of the users are male, which is 74% and most of the users are between 31-40 years
and 41-50 years of age where maximum users are between 31-40 years with 24%, followed
by user of age between 41-50 years with 22%, then users of age of 21-30 years with 19%,
followed by users with age 12 % and least being users above 51 years with 4%. It is also seen
in the survey that 42% of the users prefer Alton Towers application for their use where next
best option for them is Uber application with 26%. However many of the users think that the
app was confusing to them to use where few others have experienced bugs and lots of
advertisements as well as the app was visually unappealing and crashed while using. In the
survey, it is seen that most of the users liked visuality in the app, however few other users
liked speed, functionality, stability and navigation as well. However, many of the users also
disliked visuality more, though few others disliked speed, stability, navigation and
functionality as well, as seen from the results of the survey.
Conclusion
The report includes developing the prototype of the application for cab service by
using techniques of User Centred Design to identify issue with user experience. After
