CHAPTER ONE
1. Introduction
Insurance system is one of the important organization in the world that are becoming more spread
from time to time. Insurance system is a system in which one makes agreement to pay money to a
company and the company pays back if an accident or injury happens to the members of the
organization. The one that pays money to the company is called insured and the one that pays back
if an accident or injury happens is insurer. In other words, insured pays money to insurer. The
insured receives a contract or insurance policy which details the conditions and circumstances
under which the insured will be financially compensated. Insurance involves pooling funds from
many insured entities to pay for the losses that some may incur. The insured entities are therefore
protected from risk for a fee, with the fee or premium being dependent upon the frequency and
severity of the event occurring on the members of the organization .There are different types of
insurances given by companies such as life insurance, health insurance, auto or vehicle insurance
etc. For example, in auto insurance it will typically cover both the property risk (damage or theft
to the vehicle) and liability risk legal claims arising from an accident.
1.1Back ground of the organization
As we know Ethiopian Insurance is one of the earliest established institutes in Ethiopia. It
established its branch in Wolkite in 2004 E.C .The establishment of these institutes is expected to
give much to the ongoing development of the country in general. This system is still operate
manually .It operates all functions manually like registering, searching, reporting, editing, adding
details of information of the insured members of the institution. So this manual operation face
different types problems like it takes time for the operation, ineffective file, data inconsistent, data
not secure, etc. This is the general idea current Ethiopian insurance organization operation and
information management.
12. Page | 2
1.2 Statement of problem
Ethiopian Insurance Information management system have many problems because it perform
its operations manually. Due to this reason the institution face too many problems. More specific
problems are listed as follows:
- To search data from the manually recorded take more time and difficult.
- Less availability.
- Less secure (data can be accessed by unauthorized users or agents).
- It require higher cost.
- Difficult to handle error and input data is not validated.
- Data duplication: the same data gets repeated over and over since the workers find
it hard to keep track of the documents, information and transactions
- Inconsistency of data: there will be unavailability for future use, since data might get
misplaced during manual filing. So data won’t be preserved properly for future use.
- Files cannot be shared easily in the institution.
1.3 Objective of the project
1.3.1 General objective
To develop computerized (automated) Insurance Information Management System for Ethiopian
Insurance in Wolikite branch.
1.3.2 Specific objective
Specific objectives are objectives that used to achieve specified general objective. The following
are specific objectives.
- Study the existing system and identifying the problems under the existing system.
- Requirement analysis of the existing system with respect to functional and nonfunctional
requirement.
- Design new system based on the requirement analysis of the existing system.
- Implementing the new system.
- Testing the system using different testing methodology.
- Deploying the system the system after the system is tested.
13. Page | 3
- Maintain and update the system when needed.
1.4 Scope of the project
This project will be developing a web based Ethiopian Insurance information Management
System for Wolikite branch. The project is enable fast and available service for the insured of the
Ethiopian Insurance.
1.4.1. In scope
- This project can do the following insurance types.
Vichel (motor) insurance.

Medical insurance.
1.4.3 Limitation of the project
Our project have the following limitations:-
- Shortage of data: there is no enough information about other insurance types. Because of
this we cannot include other types of insurance.
- Shortage of time: We have shortage of time to complete the project in one semester. This
enforces our project team to minimize the project scope.
1.5 Significance and beneficiary of the project

15. Page | 5
1.6 Methodology
1.6.1 Method of data collection
There are different methods of data collection methods. From those we used the following methods
respectively to collect data from the organization.
Direct Observation: use this method to get the right information about the
organization and also understand by viewing how the existing system works.
Interview: through interviewing the manager and another employee of the
organization and we get enough and reliable data which is important to do the project.
Document analysis: we analyzing the manual resources of the organization how the
current system operates.
1.6.2 System development methodology
There are different types of software development methodologies from this we used:-
• Object oriented system analysis and design methodology: Is software development
methodology by building self-contained modules or objects. This methodology have the
following futures increased reusability, increased extensibility, proved quality, and
reduced maintenance burden and managed complexity .due to this we select OOSAD
methodology.
• Software development model: we use is iterative model because in iterative model you
can iterate back if error are occurs in one phase and we can return back to other phase to
fix errors at any phase of the project life cycle.
1.6.3 Development tool
1.6.3.1 Hardware tools required
Personal computer (PC): almost all tasks of our project are performed on
computer.
Flash disk: required for data movement to store & transfer data from one PC to
another PC.
Disks (CD, DVD): necessary for the movement, backup and recovery mechanism
of relevant data.
16. Page | 6
Paper and pen: for writing all necessary documentations associated with the
project.
1.6.3.2 Software tools required
Windows 8.1 Operating system: will be used for the system since it is readily
available in laboratories.
Firefox, chrome browsers: -since our system is web based, it is very
necessary requirement.
Microsoft office Word 2013:-for documenting the corresponding deliverables
associated with the project
Edraw max 6.8: -for designing Unified Modeling Language (UML) diagrams.
Xampp Server: - to test the system.
1.6.4 System evaluation procedure
There are different types of evaluation procedures used for testing a system. This evaluation are
relevant for is the system is go on the specified user requirement and perform all expected function
as well as to find the system gape. For our project we will use different evaluation procedures from
which.
Unit testing - individual components are tested independently. Components may be functions or
objects or coherent groupings of these entities. This used for testing each component of system
and best for finding system failure.
System testing -testing of the system as a whole. Testing of emergent properties is particularly
important.
1.7 Feasibility of the project
Feasibility study is used to investigate the proposed system in multiple dimensions. It is used to
indicate whether the system is feasible or not.
1.7.1 Technical feasibility
Technical feasibility is the measure of practicality of the specific technical support and the
availability of technical resources and expertise to use the system. The proposed system can be
easily maintained and repaired without requiring high Experts or technical supports, because the
system will be installed in adaptable technology’s and the employee of the organization have
17. Page | 7
some knowledge about technology by providing training and help how to use the system and can
use the system easily . So the system is technically feasible.
1.7.2. Economic feasibility
Economic feasibility is the process of identifying the financial benefits and costs associated with
the project being developed. So the project is economically feasible because the project reduce
the cost of the resources. But Economic Feasibility is expressed as cost- benefit analysis.
Costs- our system use new technology and have centralized database cannot need more
resources. It require minimum amount of cost. The estimate cost of resources that we use to
Develop this project.
Table 1 cost estimation
1.7.3. Operational feasibility
The system perform all operations to achieve the specified objective, User friendly and
interactive with the environment and the system will perform all operation that the organization
runs. And it will not have any difficulty or procedures to perform the operation of the system.
So the project is operational feasible.
1.7. 4 Schedule feasibility
The system after development may give efficient and effective services in short period of time.
And also the tasks may be scheduled for effective use of the system. The project will be finish at
the schedule time. So the project is Schedule feasible

criteria. We determine technical feasibility, operation feasibility, economic feasibility, political
feasibility of the project.
Determine significance of the project: we describe the significance that the system provide after
finishing.
Chapter two: this chapter deals about description of the current system: we dealing about current
system and the strength of existing system as well as the weakness of the existing system .we
identify the business rule that the existing system follow. Next to this we set the expected
outcome of our project after finishing.
Chapter three: this chapter deals about we explain what the proposed system is and identify
functional requirement, nonfunctional requirement, hardware requirement and software that the
proposed system is to do. Determine security and safety procedures for our project.
Chapter four: this chapter deals about we define system analysis and design for our projects
using system designing model and we use UML modeling system. Designed our system with two
model these model. The first is system model in this model we define and design our project
scenarios, use case diagram, and use case description, class diagram, (EER) diagram and
20. Page | 10
normalization of table. Second we design our dynamic model of our system and this includes
sequence diagram, activity diagram, component diagram, and deployment diagram, architecture
of the system, subsystem decomposition, and user interface of the project. This is our project
organization study until chapter four.
21. Page | 11
CHAPTER TWO
2. Current system
2.1 Description of current system
Wolikite Branch Ethiopian Insurance in is one of the institution in Ethiopia. This institution
perform many operations and the aim is giving guarantees for the insured of the organization .the
organization have many types of insurance .The functions performed in the organization are
manage events occurred in the insured, renew information, and handle payment. The institution
revises its policies regularly and produces new policies based on the country’s current economic
development and the demand of customers. The organization have seven employees this
employees have its own responsibility and the institution provide insurance for objects insured
value is less than or equals to one million birr. The major property and liability insurance services
given by the institution are, fire and lighting insurance, money insurance, auto insurance.
2.2 Strength in the existing system
Even if the existing system have its own weakness it have its own strength. The following are the
strength.
- The existing system is politically feasible.
- Organizational structure.
- Better for people who cannot get internet and computer access.
- Business rule of the existing system are good.
- More number of employee work on the existing system.
2.3 Weakness in the Existing system
The existing system have many problems .we classified the problem as follow.
Inputs
Data is not accurately captured if it contains errors.
Input data is not validated.
Outputs
Sometimes lack necessary and relevant information.
Sometimes Information is not in a useful format.
Information is not timely to its subsequent use.
Stored Data
Data is not flexible –not easy to meet new information needs from stored data.
Data is not accessible easily.
22. Page | 12
Costs (Budget of the office)
Stationary cost is increasing.
Service
The existing system is not that easy and it is uncomfortable to use.
The system is not easy to coordinate.
Security and Controls
Input data is not adequately edited.
Ethics are branched on data or information – refers to data or information getting to
unauthorized people.
Redundantly stored data is inconsistent in different files.
Data privacy regulations or guidelines can be violated.
Processing errors are occurring by people.
Efficiency
Performance (Response time): the response time is less.
2.4 Business rules
-Business rules that the existing system follow.
BR1: New insured fill the registration form correctly and fill all the required information.
BR2: The insured renew annually their policy and the not renew the insurance the insurer
exclude the insured from the insurance and not accountable if any accident face. .
BR3: The insured register its object.
BR4: Insured pay the premium value of the object and insured not pay this not approved or not
provide any service from the insurer until the premium value played.
BR5: Insured must report accident immediately.
BR6: Insured who cannot renew his insurance policy is dismissed from the insurer.
BR7: Insurer check accidents of insured: the insurer immediately check the accident and provide
needed support to the insurer.
BR8: Insurer pay the value of object when accident is happen.
BR9: Insurer notify insured to renew their policy.
23. Page | 13
2.5 Expected outcome of the project
The outcome of this project is generate good web based system that perform all expected
Functions with minimum resource, time and higher performance.
2.6Alternative solution
As we justifies above that the existing system have many problems. So the alternative solution to
reduce this problem replace the existing manual system to web based system this is the
alternative solution that we take to improve the existing system.
24. Page | 14
CHAPTER THREE
3. Proposed system
3.1 Overview of the proposed system
The existing system has its own problem and drawbacks. So that, the project team tries to
develop a system which is better than the existing system in terms of time and cost efficiency.
The team tire to make the existing system that improve system performance .The proposed
system is capable of provides high security of data, capability of organizing all information in a
single client-server system, easy way of recording and accessing items information by its well
organized user-friendly interface. Generally the proposed system will improve the performance
of the existing system and reduce this problems, time wastage, Bring data security, data
inconsistency, Poor quality service delivery, and reduces wastage of paper.
3.2 Functional requirements
Functional requirements drive the application architecture of a system. Functional requirements
are the intended behaviors of the system. This behavior may be expressed as services, tasks or
functions that the system is required to perform. The functional requirements that the proposed
system Perform.
- Registration of the new insured
- Payment management
- Generating report
- Delete report
- View report
- Post notice
- Delete notice
- Renew insurance
- Update insured
- Manage accidents.
- View notice
- Manage accounts.
- Manage accidents.
25. Page | 15
3.3 Nonfunctional requirements
Non-functional requirement is a requirement that describes about how the system will do the
functional requirements. It describes performance, maintainability, security, usability,
availability, accuracy, and reliability of proposed system.
Performance: The proposed system perform its operations within a minimum amount of time and
the user gets the expected result within a few seconds and the system is effective.
Accessibility: The system can be accessible based on the accessible privilege or based on
autontication.
Accuracy: proposed system will reduce error because all operation can be check correctly and
validate that whatever information is coming from the data base and input to the database.
Maintenance: our system can be easy maintainable and updateable, if the system get any failure.
Extensibility: - Adding features and carry-forward of customizations at next major version
upgrade along with the business re-engineering is possible.
Backup and recovery: to reduce data loss and other risks there shall be a frequent and full back
up mechanism to avoid any information loss and inconsistency using copy of the system to
restore when hard ware and software failure occur.
Resource: the proposed system cannot use more resources as current system because it have
centralized data base management system.
3.4 Hardware Requirement
-The hardware requirement that we use for developing this project are.
o Personal computer (PC).
o Intel(R) core™i3, CPU 2GHz and more than this is possible.
o RAM: 2GB and above possible.

requirement and it use for front end.
o Microsoft office Word 2013:-for documenting the corresponding deliverables
associated with the project
o Edraw max 6.8: -for designing Unified Modeling Language (UML) diagrams.
o Xampp Server: - To test the system will be running.
3.6. Security and Safety Procedure
3.6.1 Security Procedure
In order to make the system secure from an authorized access and modification, the system uses
a login account to differentiate among the different users of the system on the organization side.
This enables the system to verify who has logged in using the correct logging account provided
and display the right form associated with that user. The security service provided by the system
will maintain the security, confidentiality and integrity of the system. Users will have their own
autontication based on user name and password. Through which they could gain access to the
system.
3.6.2 Safety Procedure
