Systems development is systematic process which includes phases such as planning, analysis, design, deployment, and maintenance. It is a process of collecting and interpreting facts, identifying the problems, and decomposition of a system into its components. System analysis is conducted for the purpose of studying a system or its parts in order to identify its objectives.
Requirement Analysis, also known as Requirement Engineering, is the process of defining user expectations for a new software being built or modified. In software engineering, it is sometimes referred to loosely by names such as requirements gathering or requirements capturing. Requirements analysis encompasses those tasks that go into determining the needs or conditions to meet for a new or altered product or project, taking account of the possibly conflicting requirements of the various stakeholders, analyzing, documenting, validating and managing software or system requirements.
Software requirement is a functional or non-functional need to be implemented in the system. Functional means providing particular service to the user. For example, in context to banking application the functional requirement will be when customer selects "View Balance" they must be able to look at their latest account balance. Software requirement can also be a non-functional, it can be a performance requirement. For example, a non-functional requirement is where every page of the system should be visible to the users within 5 seconds.
Eliciting use cases and modeling business processes are critically important skills for the systems analyst to master. A system design team should review current GIS and hardware system technology, review user requirements, and establish a system architecture design based on user workflow needs.
