Specification model
A.Executive summary
The main goal of this project is to implement the Sunshine Motors vehicle mechanic
management system by using the “Business Enterprise Management System”. The improvement
in the process of vehicle mechanic system which follows the following stages of analyzing of the
relationship process (company service to customer), process stages, Redesigned process (work
order) will be done. The proposal to use the case diagram which is denoted as simple
representation of the customer’s interaction with the vehicle management service system that
identifies the methodology and process step of business enterprise system will be carried out.
The analysis process of the feasibility that follows the three stages includes, technical feasible,
estimate cost feasible and profit feasible will be completed. Analyzing of the Sunshine Motor
vehicle record service is based on 300 clients but Investment on increasing the efficiencies of the
production had the greatest impact on company profitability by 10%.
B. System Description
The system description structure has been used for developing the Sunshine Motors
Vehicle mechanical service company using business process model system. The new system for
improving the Sunshine Motors management system has records that includes add and update the
client information (name, address, conduct details), service information (model, color,
registration), and mechanic information of the system. The company’s system also contains the
records of employees of the company management system. The mechanical service company of
the current system is specifically for the increase in the work flow demand and improves the
company’s growth for the system. Analyzing process of sunshine’s motors current company of
the manual based vehicle system, which is specific for the good of the company, now is impacted
and damaged by additional demand and growing customers of the company.
C.Scope
The scope of this project to enhance the facilities available in the motors vehicles
management current database system and different security measures would be applicable in the
3

future and growing the customer list which shall improve the business process management. The
scope of process is to analyze the project, to involve planning and organization of the vehicle
mechanic company resources to complete the allocated task event, and service delivery to be on
time for the customer. Also, find the risk of the project which satisfies the condition of the
company. The vehicle mechanic is to satisfy the customer’s car service and provide good quality
service to the customer and after that improve the good market stages of the company.
D.Feasibility analysis
The feasible study of the vehicle management system includes the following stages,
 Technical feasibility
 Operational feasibility
 Economic feasibility
 Legal feasibility
Technical feasibility
Technical Feasibility of the business enterprise system can specify the software
equipment which shall successfully satisfy the customer (car service) and also the company
(delivery process) requirement for the system.
Operation feasibility
Analyzing of the operation feasibility can measure customer solving problems and in turn
can help for the new proposed system. The operation feasibility of the initial stages is analyzing,
planning, and implementing on the business process model system. The process of the operation
fulfills the customer requirements and identifies the duration of the development of the economic
profit service.
Economic feasibility
Economic feasibility analysis is the most commonly used method for determining the
efficiency of new services.
Legal feasibility
Legal Feasibility can be used for checking the each stage of the process model to occur
and the risk to correct the service of the system.
