Explain Organizational approach to System Analysis and Design
9966 [12]

Answer:

The major goal of systems analysis and design is to improve organizational systems. Often this process involves developing or acquiring application software and training employees to use it. Application software, also called a system, is designed to support a specific organizational function or process, such as inventory management, payroll, or market analysis. The goal of application software is to turn data into information. For example, software developed for the inventory department at a bookstore may keep track of the number of books in stock of the latest best seller. Software for the payroll department may keep track of the changing pay rates of employees. A variety of off-the-shelf application software can be purchased, including WordPerfect, Excel, and PowerPoint. However, off-the-shelf software may not fit the needs of a particular organization, and so the organization must develop its own product.

Explanation:

Information systems analysis and design is a method used by companies ranging from IBM to PepsiCo to Sony to create and maintain information systems that perform basic business functions such as keeping track of customer names and addresses, processing orders, and paying employees. The main goal of systems analysis and design is to improve organizational systems, typically through applying software that can help employees accomplish key business tasks more easily and efficiently. As a systems analyst, you will be at the center of developing this software. The analysis and design of information systems are based on:

Your understanding of the organization’s objectives, structure, and processes

Your knowledge of how to exploit information technology for advantage

gulaghasi [49]

Answer:

A lot is wrong with the program given in the question. See the corrected version below:

<em>public class ANot {</em>

<em>    public static void main(String[] args) {</em>

<em>        int a, b, c;</em>

<em>    //Three integers</em>

<em>    a = 3; b = 4; c = a + b;</em>

<em>        System.out.println("The value of c is " + c);</em>

<em>    }</em>

<em>}</em>

Explanation:

Errors:

1. The main method had a semi colon after it. This is wrong

2. An open brace was supposed to follow the main method

3. The declaration of the variables was supposed to end with a semi colon

4. the correct comment style is // and not \\

5. Initialization of variables was supposed to end with semi colons

6. The output statement had C and not c which is the declared and initialized variable..Java is strictly typed

7. Open and closing braces for the class and method wrongly placed
