TAILIEUCHUNG - Lecture Enterprise systems development (CSC447) - Lecture 16

After completing this unit, you should be able to: Define the traditional systems development life cycle (SDLC) and describe the seven major phases within it, compare and contrast the various component-based development methodologies, describe the selfsourcing process as an alternative to the traditional systems development life cycle,. | Lecture 16 Enterprise Systems Development ( CSC447) COMSATS Islamabad Muhammad Usman, Assistant Professor College of Statistical and Acturial Science Architecting Process SA Process Outline The architect must typically Work with the requirements team Work with various application stakeholders Lead the technical design team Work with the project management Architecting Process Architecting Process Determine Architectural Requirements Also called architecturally significant requirements or architecture use cases, are quality and nonfunctional requirements Identifying ASR Determine Architectural Requirements Identifying ASR : QAs and Constraints Determine Architectural Requirements Identifying ASR : QAs and Constraints Determine Architectural Requirements Priortize ASR Initially, it’s usually sufficient to allocate each requirement to one of three categories, namely: High: the application must support this requirement. These requirements drive the architecture design 2. Medium: this requirement will need to be supported at some stage, but not necessarily in the first/next release 3. Low: this is part of the requirements wish list. Prioritization gets trickier in the face of conflicting requirements Good architects know how to say “no”. Architecting Process 2. Architecture Design Wonderful requirement documents and attentive networking with stakeholders mean nothing if a poor design is produced. Design is typically the most difficult task an architect undertakes. Good architects draw on several years of software engineering and design experience. There’s no substitute for this experience Architecting Process 2. Architecture Design The design stage itself has two steps, which are iterative in nature. The first involves Choosing an overall strategy for the architecture, based around proven architecture patterns. The second involves specifying the individual components that make up the application, showing how they fit into the .
