Model-driven Analysis Before going into the discussion on how model-driven analysis benefits information systems, let us get a better understanding of what model-driven analysis actually is. Model-driven analysis provides a set of concepts to the system developers, which help them design graphic models to validate both proposed and existing systems. A proper analysis of project requirements is a key to start the design phase of the system development. After project planning phase, system developers focus towards analysis of the project requirements and other details.

Learning the conceptual framework for the analysis technique is the most important aspect of model-driven analysis. The main purpose of system development is to develop an information system that should be able to meet business and personal needs of the users. Model-driven analysis can really benefit the development of information systems by providing a proper set of guidelines regarding system development to the developers. The main benefits of developing information systems include proper management of business related information, documentation of the collected information, and assisting managers in the processing of information.

A model-driven technique helps developers draw such models, which can be used for various purposes, such as, to gather business related information, to prioritize requirements, and to review recommendations to develop an efficient information system. System developers use model-driven technique to develop such systems, which can be used for collecting business related data and for processing, analyzing, and disseminating collected data to the concerned departments in the form of information. Therefore, we can say that model-driven analysis plays a considerable role in developing efficient information systems.

Fact-Finding MethodsSampling In this method, developers use documentations of problems, reports, files, and case studies for collecting information. Sampling of existing documentation and databases is a good way to gain understanding of the whole system.Observation In this fact-finding method, developers try to understand the system by either participating personally in different activities or watching other people perform those activities. Observation allows developers check validity of the facts and obtain relevant data.

Research In this method of fact-finding, internet, reference books, and previous researches on the same system are used to gather information. These sources make developers know how other people have been successful in developing somewhat similar systems in the past.Questionnaires In this method, questionnaires consisting of different questions are distributed among a large number of people to know how people think about the system. Questionnaires provide real fats and information to the concerned authorities.

Interviews In this fact-finding method, different people are interviewed to know their viewpoints. “Analysts can use interviews to collect information about the current system form the potential users” (Ravindran, 2007).Prototyping This fact-finding technique is used in such situations where developers find it difficult to define system requirements. It is a good method to determine the usefulness and feasibility of the system before developing the system.Joint Requirement Planning This method is used in such situations in which developers have to obtain group consensus on system requirements and problems related to the system.

This method is a very good one to reduce the system development time.Meetings It is also an effective method to know viewpoints of experts. In this method, developers of the system sit together in a conference room and discuss different facts related to the proposed system.ReferencesRavindran, C. (2007).
