TAILIEUCHUNG - Lecture Web technologies and programming – Lecture 3: Requirement engineering - Modeling web applications

After studying this chapter you will be able to understand: Project management, responsibilities/tasks of a project manager, (planning, risk management, people management, reporting, proposal writing), traditional vs. web project management. | CIIT-Human Computer Interaction-CSC456-Fall-2015-Mr. Tehseen Riaz Abbasi 1 2 Modeling web applications 3 Modeling web applications 4 Development Process model software development process activities Requirement for a web development process model Rational unified process model (RUP) suitability for web application development 5 Project management Responsibilities/tasks of a Project manager Planning Risk management People management Reporting Proposal writing Traditional vs. web project management Introduction to RE RE basics Requirements specification RE process RE specifics in web engineering System modeling Modeling requirements 6 Requirements Engineering: the principles, methods, & tools for drawing, describing, validating, and managing project goals and needs Given the complexity of Web apps, RE is a critical initial stage activity, but often poorly executed 7 It may range from a high-level abstract statement of a service or of a system constraint to a detailed mathematical functional specification. The processes used for RE vary widely depending on the application domain, the people involved and the organisation developing the requirements. However, there are a number of generic activities common to all processes Requirements elicitation; Requirements analysis; Requirements validation; Requirements management 8 9 The requirements engineering process 10 Costs: Inadequate software architectures “Unforeseen” problems budget overruns production delays “that’s not what I asked for” Low user acceptance 11 Why requirement engineering: requirements don’t define themselves (Bell & Thayer, 1976) removal of mistakes post hoc is up to 200 times more costly (Boehm, 1981) iterative collection and refinement is the most important function of a software engineer (Brooks, 1987) 12 Why requirement engineering: A study based on 340 companies in Austria, more than two thirds consider the SRS as the major problem in development process (1995) A study on Web applications, 16% .
