SECTION B
Case Study -
A commercial organization performs various activities. The important ones among them include financial accounting, inventory control, and payroll. Most of these activities are carried out manually. As the dimensions of these activities increase, the organization may prefer to mechanize the activities to operate smoothly. Computer manufacturers have come to the rescue of business organizations. They have developed packages/programs, for carrying out the activities like payroll preparation, inventory control, invoicing system, and financial accounting.  A computer software package on payroll thus becomes an integral part of a large business organization. Similarly, financial accounting is another field where computerization can play an important role. The financial accounting package is one which helps the organization in preparing various financial reports, ledgers, and journals of monetary transactions. In a large production-oriented organization, it is essential to have a control over the investment in inventory of raw materials. A computerized inventory control system can reduce considerable amount of time in processing the data which is necessary to control inventory. Software development for business applications is not an easy task. In developing a large software (e.g., MIS), many people are involved and many months or even years are spent. However, a small application (e.g., Payroll) can be developed in few weeks or months by a single or few programmers. For such small systems, software development activities maybe done implicitly without proper documentation. But, for large systems, these activities must be done explicitly with proper planning and documentation. Whether a system is small or large, software development revolves around a life cycle that begins with the recognition of users' needs and understanding their problem.

Q. 1. Feasibility study is the first phase in development of a new system. Describe the various steps to perform feasibility study.

Q. 2. Financial accounting is one of the field where computerization can play an important role. Justify the statement in detail.

    
Q. 3. Explain the role of computer system in the successful operation of business organiztion.
