Question:

Explain IT System and Analysis.

Answer:

Data flow diagram

The data flow diagram for response and reporting system are as –

Process used by analyst for analyzing data oriented systems

As mentioned by Bauer, Vom et al. (2009), data oriented systems help system analyst to complete the process is structural manner. The data oriented system used by system analyst for analyzing enquiry request and response system is data flow diagram Vom et al., (2009). Zero level data flow diagrams help the system analyst to decide the complete procedure of enquiry approval and analysis Kusic, G. (2009). As commented by Goetz (2010), data oriented diagram help system analyst to analyze each and every process. The request and response process of every enquiry involves many steps (Mortazavi & Jalili, 2014). Every person involves in request and response processes are having their own set of responsibilities Mortazavi & Jalili (2014). As a system analyst of MRE Corporation, analysis of each process is very important. It helps in improving the enquiry and response system of company.

Use of decision tables, trees in structured decision process

As commented by Gra?§bczewski (2009), the structured decision making process involves several steps. As a system analyst of MRE Corporation, for making decision flowcharts, data flow diagram and others are used (Vom et al., 2009). It helps in making structured decision, that is, decision which involves step by step process. In context to this Kusic (2009) stated, every top level and middle level manager play important roles in the decision making process. On the other hand, the decision tree helps in analyzing the process, by using different graphs and models. As mentioned by Mortazavi & Jalili (2014), decision tree help in analyzing the decision and making changes in it. As a system analyst, decision is taken after analyzing the complete problem and the reason (Vom et al., 2009). Decision tree help in making structured form of all process and people involved in decision making process.

Analysis method used for analyzing structured decisions and for creating process of specifications

As commented by Omer (2013), structured decision process involves step by step process. Structured decision making can only be completed, when all process are completed on time. The enquiry request and response system decision can only be completed with the help of decision tree and tables (Mortazavi & Jalili, 2014). For example, suppose training request is raised for few employees from training department (Vom et al., 2009). Then the final decision for training will be taken after analyzing the requirement of training. To explain who request process to manager’s system analyst has to create decision tree and tables.
