The Sampling Of Existing Documentation Information Technology Essay

System analyst uses sampling techniques in order to organize the above documentation. Sampling technique is the process of combing a representative sample of documents, form and records (Bentley, Whitten, 2007). According to these authors there are two commonly used sampling techniques namely randomization and stratification. Randomization is the process of selecting sample data randomly. Stratification is the systematic process to deduct the variance of sampling data. We can have better understanding of the system due to the analysis of existing documents, forms, files related to the current system.

JRP is the structured group work meeting to identify, analyze problems and define the requirements of system. JRP is becoming increasingly common in systems planning and systems analysis to obtain group consensus on problems, objectives and requirements (Bentley and Whitten; 2007). JRP can tabulate the facts efficiently in a short time and it can also replace in the place of numerous and separate interviews. JRP contains different participants with each specialized roles to perform structured meeting. JRP participants include sponsor, facilitator, users and managers, scribes and IT staff. Sponsor is an individual in top management, who has full authority to decide who will be participants, time and location of JRP session. The role of facilitator is to lead JRP session, motivate participants, solve conflicts and meet the requirements of meeting during the JRP session. Users in JRP session are responsible for rules and requirement of business, prototype, and satisfactory decisions. And Managers are responsible for projects, schedules and costs and training requirements. Scribes job is to record everything discussed in the meeting. IT staff responsible for models and documentation concerning with facts during the discussion.

JRP is formed different individuals with various roles and covers both in users and in management levels. JRP saves time to develop systems as it is not required one-on-one interviewing of each participant within the organization. When JRP incorporates prototyping as a means for confirming requirements and obtaining design approvals, the benefits of prototyping are realized (Bentley and Whitten; 2007).

In this paper we discussed about the seven fact-finding techniques based on studying our text book and some articles. During our assignment, we become to understand that if the system analyst knows details of fact-finding techniques, they can get knowledge of gathering the required information to develop the current system.
