What is the traditional approach to systems development?

As a part of preliminary investigation in system analysis phase there are several fact finding techniques,which are described how they are useful to traditional approach to system development as follows.

Document Review:-

The Document Review is a very useful technique whose main intention is to get the forms or documnetation of the current system .But the system analyst should be very keen that the collected documents are the latest which are presently used by the system.

Observation:-

The other important fact finding technique in traditional approach is observation.Observing the current operations gives the extra information and a deep understanding of the current procedures.Observation also verifies whether the staements of the interview and the documents produced by the company are exactly same or not.

Questionnaires and surveys:-

Sampling:-

As a process of fact finding technique sampling is done for a sample of individuals of the organization.There are different methods in sampling for example, systematic sampling, stratified sampling and random sampling.

Research:-

Research is also a useful fact finding technique .system analysts can attend the professional meetings,seminars and IT workshops to get more understanding and knowledge which is useful to learn more about the current system.

What is the Object-Oriented approach to systems development

The object -oriented analysis uses a popular fact finding technique called Joint Application Development.In JAD technique mainly the users have important responsibility and they are active participants in the development process .The IT staff will meet the users initially and they also interact with the users through out the development of the new system.The users involve formally and informally in every stage.One popular method is the JAD team approach ,which consists few users ,managers and IT professionals ,they work together in collecting the information defining new system.

What text books ,journals and /or websites might be useful to search for articles about comparing and contrasting the traditional and object -oriented approaches to systems development?

Research is the important fact finding technique.A lot of information can found through the internet,IT magazines and academic books to obtain information about the traditional and object-oriented approaches to systems development.Research through internet is also helpful in finding information from various kinds of sources including  government sites,other publishers and libraries around the world.Site visit is also a part of reasearch which means ,visit the physical location.The main aim is to observe a system of another organization and their processes.
