Process specification in system analysis and design. Its objective is to flow down and specify regulatoryengineering requirements and procedures. This specification allows an analyst to work on or review any process and to locate the data flow diagram containing the process easily. Overview of process specifications. A requirements specification which is a document providing a detailed description of the issue or project and the requirements identified to either fix it or make it happen.
It involves all the tasks that are conducted to identify the needs of different stakeholders. It consists of the following steps specifying the inputoutput media designing the database and specifying backup procedures. Incorporation of design considerations including statutory and regulatory constraints see ch 343. A process specification is a method used to document analyze and explain the decision making logic and formulas used to create output data from process input data.
Requirements analysis is the process of defining the expectations of the users for an application that is to be built or modified. High quality consistent data requires clear and complete process specifications. It produces the working system by defining the design specification that specifies exactly what the candidate system does. It is concerned with user interface design process design and data design.
In the design phase analysts design all aspects of the system provide physical specifics on the system from input and output screens to reports databases and computer processes. 1 in the effort to improve the systems analysis and design processes different approaches have been developed. Systems design it is a process of planning a new business system or replacing an existing system by defining its components or modules to satisfy the specific requirements. Before planning you need to understand the old system thoroughly and determine how computers can best be used in order to operate efficiently.
The requirements analysis process provides. The systems analyst must understand the principles of organizations and have a working knowledge of data gathering techniques. The traditional waterfall approach focuses on compartmentalizing project into several phases. Therefore requirements analysis means to analyze document validate and manage software or system requirements.
Translation of end user needs usually stated in operational terms to unambiguous verifiable and feasible system performance specification requirements. Enter the following information. Depending upon the size of a project it may range from a page or two to a significant document for review and authorisation by management. To determine the human information requirements of a decision analysis strategy the systems analyst must first determine the users objectives along with the organizations objectives using either a top down approach or an object oriented approach.
