DESIGN AND
IMPLEMENTATION OF A COMPUTER BASED QUALITY ASSURANCE MONITORING SYSTEM
(CASE STUDY
OF ETISALAT NIGERIA)
ABSTRACT
This project
is about the design and implementation of a computer based quality assurance
monitoring system. A quality assurance monitoring is very necessary as it will
contribute to the corporate performance of an organization. The method used in
implementing the design was based on top-down approach. This is done by
starting with the general concept of what is required by the existing system
that it is lacking and breaking them into component parts which are then
simplified with the introduction of the new system. More features can
still be added to the system to make it more reliable for efficient results. .
The new system was designed using Microsoft visual basic 6.0 programming
language. This language was chosen because of its easy syntax and features for
developing windows based applications.

CHAPTER ONE
1.1 INTRODUCTION
An organisation will benefit from
establishing an effective quality assurance monitoring system. The cornerstone
of a quality organisation is the concept of the customer and supplier working
together for their mutual benefit. For this to become effective, the
customer-supplier interfaces must extend into, and outside of, the
organisation, beyond the immediate customers and suppliers.
Quality assurance is the
process of verifying or determining whether products or services meet or exceed
customer expectations. Quality assurance is a process-driven approach with
specific steps to help define and attain goals. This process considers design,
development, production, and service.
The most popular tool used to
determine quality
assurance is the Shewhart Cycle, developed by
Dr. W. Edwards Deming. This cycle for quality assurance consists of four steps: Plan, Do, Check,
and Act.
These steps are commonly abbreviated as PDCA.
The four quality assurance steps within the PDCA model stand
for:
Plan: Establish objectives and processes required to deliver
the desired results. Do: Implement the process developed. Check: Monitor and
evaluate the implemented process by testing the results against the
predetermined objectives Act: Apply actions necessary for
improvement if the results require changes.
PDCA is an effective method for monitoring quality assurance because it analyzes existing
conditions and methods used to provide the product or service customers. The
goal is to ensure that excellence is inherent in every component of the
process. Quality
assurance also helps determine whether the
steps used to provide the product or service is appropriate for the time and
conditions. In addition, if the PDCA cycle is repeated throughout the lifetime
of the product or service, it helps improve internal company efficiency.
1.2 STATEMENT OF THE PROBLEM
There has been a constant quest by man since creation
to improve on the quality of his life and existence, this ever increasing quest
has been necessitated and propelled by the simple need for man to address the
challenges posed by his environment. Some of the challenges associated
with Phone Calls include.
1. Poor
Quality: The sound quality is not clear and sharp.
There are noise and distortions when calls are being made.
2. Security: Sometimes the issue of security of identity
might not be guaranteed.
3. Capacity: The digital network service cannot allow more
calls to be handled at a time.
4. Tariff: Depending on the distance within the
country the service rate differs.
1.3 OBJECTIVE OF THE STUDY
The primary
objective of this study is to design and implement a computer based quality
assurance monitoring system. This will ensure that two important requirements are met:
1. The
customers’ requirements – confidence in the ability of the organisation to
deliver the desired product and service consistently meeting their needs and
expectations.
2. The
organisation’s requirements – both internally and externally, and at an optimum
cost with efficient use of the available resources – materials, human,
technology and information.
1.4 SIGNIFICANCE OF THE STUDY
The
importance of this research work is based o the following:
1.
It will help to solve the problem faced by administrative and
marketing department
2.
It enables an organisation to
achieve the goals and objectives set out in its policy and strategy.
3.
This research work will equally be valuable for students who may
carryout similar research in related field for reference purposes.
This will
also assist other organization and system designers to completely design a
computer based quality assurance monitoring system which will in turn make for
efficiency, smooth and better performance of administrative activities.
1.5 SCOPE OF THE STUDY
The main
objective of this study is to identify a better way of designing and
implementing a computer based quality assurance monitoring system that will
totally reduce the problems faced by the existing system. The study is
narrowed down to Etisalat Nigeria for the computation of Subscribers’ call and
quality of service rendered. It was the range of perception or understanding
which gave rise to the action taken in implementing the desired program,
designed to handle pools of complaints, criticism and suggestions by
subscribers. This will help in the effective and efficient tracking of
information on subscriber’s activity as well as monitoring the administrative
and marketing activities.
1.6 LIMITATIONS OF THE STUDY
A number of
factors militated against this project which poses some difficulties, they are
as follows;
1.
Unwillingness of the respondent to release basic and necessary facts.
2.
Cost of sourcing of information from relevant journals, materials, Internet and
respondents at the administrative area is exorbitant
3.
Insufficient material at the school library has also militated on the progress
of this research as most of the books in the library are irrelevant to this
study.
4.
The stress of combining lectures and research work has not being easy on my own
part.
1.7 DEFINITION OF TERMS
For a clear
understanding of the terminology and the following terms are hereby
operationally defined.
CHANNELS: These are
voice channels that each call uses to connect on the network.
COMPUTER: This is a device that works
under the control of stored programs, automatically accepting, storing and
processing of data to produce information which is the result of that
processing.
CONGESTION: Congestion
is the unavailability of network to the subscriber at the time of making a
call.
CREDENTIAL: This
is an electronic representation of your identity; it links an individual to a
technology such as personal identification numbers, usernames and passwords.
DATA
SERVICE: The data service like SMS fax, offered by GSM makes
things easier for people.
DATABASE: This is a single organized
collection of structured data stored with a minimum of duplication of data
items so as to provide a consistent and control of pool of data.
ENTITY: This is anything about which
data can be stored.
G.S.M: Global system for mobile
communications.
INFORMATION: this
is a fact about something and it also a data that has been converted into a
more useful or intelligent form for decision making.
OPERATOR: These are
the network service providers.
PROGRAM: This is a set of instructions
that is written in the language of the computer.
SUBSCRIBER: These are
individuals that are subscribed to the network and can only use the network services
if they have the sim card.
SYSTEM: here, it means a computer
system that is aimed or designed to provide efficient means of information
storage and retrieval of data files.
RECORD: This is a written account of
something that is kept so that it can be looked at and used in the future.
