Systems Analysis and Systems Design

Introduction

In this paper, we will present a discussion on the systems analysis and system design in detail. Later on, we will be discussing the different components of business information system, and rich pictures, soft system methodology, system development life cycle, and data flow diagramming and information flow diagrams.

System analysis and system design are the two main components of the system development. Systems design involves the planning of a new business system or the process of enhance or replace the existing business system. On the other hand, system analysis involves gathering of all the facts and figures, and then analyse them by diagnosing the problems and making recommendations for improvement of the system.

In the system design, before planning of a new business system, one must have the complete knowledge of the old system and should also know how to use the computers in a best way to make the operation more effective and efficient.

Discussion

Businesses Information System

The business information system has the following main components; which are hardware, software, data, processes, people and communications. The business information system can be described as the system which helps in the integration of the people, information technology, and the business. It brings along the information modules and functions of the business together to establish the efficient channels of communication which may be used to make the accurate and timely decisions and also to contribute in the productivity and competitiveness of the organisation.

The concept of the business information systems may be helpful for achieving the strategic alliances, partnerships and global outsourcing to make the firm competitive in terms of quality, price, dependability, flexibility and responsiveness. It also highlights the new techniques, strategies, technologies and tools in developing the suitable information system (Bocij 2008, 90).

Rich Pictures

Rich pictures are part of the soft system methodology, and it offers a system through which one can learn about the complexities and problems of the business system by drawing rich representation of the problems. Here, the term 'rich' is used to represent the detailed analysis of the problems and complexities (Shelley 2010, 134).

Rich pictures are helpful in relating ones experiences and perceptions with the given situation of the problems by having the identification of the series of linked concepts. These pictures just not only record the problems of a given situation to create an art work, but they are also the part of the understating process. If one uses the metaphor in the rich pictures, they would be difficult to be interpreted by other people.

Soft System Methodology (SSM)

It is an approach to deal with the problems of the real world. There is a misunderstanding regarding the concept of the soft system methodology that they only deal with the soft problems which involve the social, psychological, and cultural factors. However, this is not true since this method does not deal with solely hard or soft problems; but ...
