Question 1 [ ] 1- What is the main goal for software engineering? Solving customer problem by systematic development and produce high quality software within cost, time and other constraint. 2- When do you consider software as success software? when it meets the needs of the people who use it. when it performs flawlessly over a long period of time. when it is easy to modify and even easier to use—it can and does change things for the better. 3- Describe a couple of things that software engineers might do besides writing the code for a program? Direct software programming and development of documentation. Prepare reports and correspondence concerning project specifications, activities and status. Modify existing software to correct errors, to adapt it to new hardware or to upgrade interfaces and improve performance. Analyze information to determine, recommend and plan installation of a new system or modification of an existing system. Develop and direct software system testing and validation procedures. Question 2 [ ] 1- What make software engineering different from problem solving in other engineering filed and sciences? A rapid change occurs while the problem is being solved. Knowledge acquisition is a nonlinear activity especially in SE. The addition of a new piece of information may invalidate all the knowledge we have acquired for the understanding of a system. The product (software) of SE is not a concrete thing like a building and can be seen. 2- What is the relation between software engineering and computer science? Some knowledge of computer science is essential for software engineers in the same way that some knowledge of physics is essential for electrical engineers. Question 3 [ ] 1- How does software engineer deal with complexity in large projects? There are many ways in software engineering to deal with complexity. Using: Abstraction (Modeling), decomposition, hierarchy System models: Show the technical aspects Task models: Show the project management aspects Issue models: Show the negotiation aspects
