Time: 45 hours Free Certificate Software engineering is a discipline that allows us to apply engineering and computer science concepts in the development and maintenance of reliable, usable, and dependable software. Today, many practitioners still debate over the term software engineering, often arguing that this discipline does not meet the criteria of engineering; rather, it should be called software development. There are several areas to focus on within software engineering, such as design, development, testing, maintenance, and management. Software development outside of the classroom is a very complex process, mostly because real-world software is much larger and more complex. The purpose of this course is to present software engineering as a body of knowledge.
In systems engineering and software engineering, requirements analysis encompasses all of the tasks that go into the investigation, scoping and definition of a new or altered system. Requirements analysis is an important part of the system design process, whereby requirements engineers and usiness analysts, along with systems engineers or software developers, identify the needs or requirements of a client. Software requirements engineering is a communication-intensive activity, at a minimum involving analysts, developers, business stakeholders and end users. The paper describes how use cases can be used effectively to model requirement of system and how it can be used as a means of communication between analyst and end users.
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.
