Engineering American Engineers Council’s Definition  "The creative application of scientific principles to design or develop structures, machines, apparatus, or manufacturing processes.  Engineering is the discipline of acquiring and applying scientific and technical knowledge to the design, analysis, and/or construction of works for practical purposes. Definition

Software Engineering IEEE Definition  Application of a systematic, disciplined, quantifiable approach to the development, operation, and maintenance of software Definition

Software Engineering Knowledge, tools, methods for:  Requirements.  Design.  Implementation.  Testing  Maintenance  Documentation Definition

Requirements Simply the process that encompasses eliciting, representing, and validating software requirements (What the software shall do, and how well shall it do it)  Completeness.  Clearness.  Testability.  Testing  Consistency  Minimality Definition

Design a process of problem-solving and planning for a software solution.  Robustness.  Extensibility.  Modularity.  Reuse.  Usability.  Security. Definition

Testing Making sure the system runs as specified.  Test planning.  Test development.  Test execution  Test Reporting. Definition

Maintenance The modification of a software product after delivery to correct faults, to improve performance or other attributes, or to adapt the product to a modified environment  Adaptability to user feedback  Adaptability to new software/hardware technologies.  Adaptability to general enhancements. Definition

Software Engineering Encompasses knowledge from:  Computer Engineering  Computer Science  Mathematics  Management  Quality Assurance  Human Factors Engineering Definition

CE Deals with designing, developing, and operating computer systems. At its core, Computer Engineering concentrates on digital hardware devices and computers, and the software that controls them. Advanced courses focus on standard designs and techniques for specific application domains. In contrast to CS and SE, Computer Engineering emphasizes solving problems in digital hardware and at the hardware-software interface. Vs. Computer Engineering

CS focuses on understanding, designing, and developing programs and computers. At its core, Computer Science concentrates on data, data transformation, and algorithms. Advanced courses present specialized programming techniques and specific application domains. The CS program is less structured than the CE and SE programs, giving students more flexibility to build depth or breadth in a variety of application domains or in the fundamentals of Computer Science. Vs. Computer Science

An information technologist tends to apply available technology to solve real- world problems for people. Areas of interest: Data Management (e.g. Data mining, Data drilling), Data storage (Database, data networking), Data security, Computer programming. Again there is no emphasis on the software lifecycle, production, management, design, testing, documentation. Vs. IT

SE deals with building and maintaining software systems. It is more software- oriented and has a greater emphasis on large software applications than Computer Engineering. It is more applied than Computer Science, placing greater emphasis on the entire software development process, from idea to final product. It is also more disciplined than Computer Science, applying more systematic practices to help ensure that products are reliable and safe. SE curricula are “deeper” than IT in that there are more required prerequisites for the intermediate and advanced courses in CS and SE. The typical SE application involves writing large programs from scratch using traditional programming languages and focusing on software architecture, data structures and algorithm development issues SE

To develop complex software programs of the highest quality, on time, and within budget.  Hardware received a lot of care in planning, and designing because it cant be changed, but software didn’t.  Programmers only cared about writing an efficient code.  Software got more complex, and its users grew.  A huge team works on software.  Reuse, Robustness, Quality, Ease of use became important.  Safety Critical Systems. Why Software Engineering?
