Question

Please need serious and professional help!

Hello! I am working on an "object oriented analysis and design" Project. I would really need your sincere help in creating a vision document for this project.

The Things That I require in the "vision document" is:

1. Product Overview

[This section provides a high level view of the product capabilities, interfaces to other applications, and system configurations. This section usually consists of three subsections, as follows:

•          Product perspective

•          Product functions

•          Assumptions and dependencies]

1.1   Product Perspective

[This subsection of the Vision document puts the product in perspective to other related products and the user’s environment. If the product is independent and totally self-contained, state it here. If the product is a component of a larger system, then this subsection needs to relate how these systems interact and needs to identify the relevant interfaces between the systems. One easy way to display the major components of the larger system, interconnections, and external interfaces is with a block diagram.]

1.2   Summary of Capabilities

[Summarize the major benefits and features the product will provide. For example, a Vision document for a customer support system may use this part to address problem documentation, routing, and status reporting without mentioning the amount of detail each of these functions requires.

Organize the functions so the list is understandable to the customer or to anyone else reading the document for the first time. A simple table listing the key benefits and their supporting features might suffice. For example:

Description of the Project: (for your help to understand)

Title: Islamabad Electric Supply Company (IESCO) Online System   

1)      Purpose and Idea:

This system is needed to help ensure that the IESCO electric company keeps record of all the incomings and outgoings transactions within and outside the company. The company also needs to keep track of all the customers and their bills. The company will also store the information of the employees working in the company. The employee’s detail such as salary and attendance will also be stored as well. This system decreases a significant amount of paper work and removes human errors while doing transactions.

2)      Aim:

The system is designed after various incidents that happened all across Pakistan where companies lost their important data and faced serious financial damage. We have seen a lot of times whenever a company or firm catches fire; all the important paperwork is lost. So to reduce the company’s cost and damage this system will be designed. This system also ensures that no employee makes unwanted changes in the company’s private data. Since, all the data would be loaded into the system, the user can verify his/her record by searching for it. Whenever an employee puts in a query the system shows result within no time which saves a lot of time. Another important advantage of this system is that if customers inquire about their bills they must be able to view it and pay it online. An invoice must also be generated when any kind of transaction is performed.

Scope:      

IESCO (Islamabad electric supply company) online system enables customers to view their billing and online payments of their respective account. It also includes employee’s personal details as well as his attendance details, which can be monitored by his seniors. IESCO online system manages the human resource requisite with quality and efficiency by decreasing the labor work for both the employees as well as customers. The major task of the system is to build an automated error free online system. This can be used for future statistics in order to calculate the data and can be further used thus easily optimizing the high degree standards of electric supply and its values, customer details, and employee details

Objectives:

IESCO online automated system will be developed to maintain the billing record of customers and details such as salary, attendance of company’s employees. The primary users of this system will be customers and employees who are managing the system. It will provide a GUI interface to handle different billing operations performed by online customers and queries of company’s employees (both technical staff and managerial staff). The system is targeted to achieve accurate and consistent data, elimination of data redundancy to some extent, and to avoid human errors.

Problem Statement:

As we have seen over the past decade that there are many problems with the online electricity bill payments. The foremost issue is that sometimes bills get shuffled on different addresses and people have to face a lot of trouble. This system offers a unique feature that is if any customer does not get his/her bill until two days before the given due date by post, he/she can complain online and can get his/her bill to be paid online. Second, the system will ensure that there are no human errors involved in the calculation of final bill to be paid by any customer. Third, it would be easy to trace all the people who do not pay their bills and still use electricity by unfair means while still being registered customers of IESCO. Finally, people often lose their previously paid bills so this system offers complete security that all the previously paid bills of customers are saved along with their payment dates. Also, employee details will be stored, which will facilitate the employees to see their progress.

Description:

The system will consist of back end data structures (classes) to store all the information and a graphical user interface (GUI). There will be separate sections for customers and company’s employees. It will also provide total security to all the company’s critical data as no one would be able to access the system other than company’s staff.

Answer 1

Object-oriented analysis and design (OOAD) is a popular technical approach for analyzing and designing an application, system, or business by applying object-oriented programming, as well as using visual modeling throughout the development life cycles to foster better stakeholder communication and product quality.

According to the popular guide Unified Process, OOAD in modern software engineering is best conducted in an iterative and incremental way. Iteration by iteration, the outputs of OOAD activities, analysis models for OOA and design models for OOD respectively, will be refined and evolve continuously driven by key factors like risks and business value.

The purpose of any analysis activity in the software life-cycle is to create a model of the system's functional requirements that is independent of implementation constraints.

The main difference between object-oriented analysis and other forms of analysis is that by the object-oriented approach we organize requirements around objects, which integrate both behaviors (processes) and states (data) modeled after real world objects that the system interacts with. In other or traditional analysis methodologies, the two aspects: processes and data are considered separately. For example, data may be modeled by ER diagrams, and behaviors by flow charts or structure charts.

The primary tasks in object-oriented analysis (OOA) are:

• Find the objects
• Organize the objects
• Describe how the objects interact
• Define the behavior of the objects
• Define the internals of the objects

Common models used in OOA are use cases and object models. Use cases describe scenarios for standard domain functions that the system must accomplish. Object models describe the names, class relations (e.g. Circle is a subclass of Shape), operations, and properties of the main objects. User-interface mockups or prototypes can also be created to help understanding.
