The difference between a software engineering and a system engineering?

A: Systems engineering and software engineering are two completely different concepts, the first system design, then to do software. Software engineering refers to some of the principles and design specifications that need to be adhered to in the development. Systems engineering includes two aspects of software and hardware. The so-called system architecture is some embodiment of systems engineering.

The main problems faced by software engineering.

A: The challenge of diversity: the need to develop new technologies and produce reliable software that is flexible enough to respond to this diversity. The challenge of delivery: to shorten the handover time of large and complex systems without compromising the quality of the system. The challenge of trust: Research can demonstrate the technology of software credibility.

Is the three phases of software development The most important phase of the engineering program?

A: Software engineering has three phases, each of which is important:

Definition phase: Feasibility Study preliminary project plan, demand analysis;

Development stage: Summary design, detailed design, implementation, testing;

Operation and Maintenance phase: operation, maintenance, disposal.

What is the goal of the four software testers?

A: The goal of the software tester is to identify software defects as early as possible and to ensure that they are repaired.

What is the purpose of the five software tests?

A: The first is to confirm the quality of the software, on the one hand is to confirm that the software did what you expect to do, on the other hand, the software to confirm the correct way to do this thing. The second is to provide information, such as providing feedback to developers or program managers, for information about the risk assessment. The purpose of the third software test is to ensure that the entire software development process is of high quality.

Why is it usually said that the product specification is the largest source of manufacturing defects in software products.

A: The product specification is often not written, other reasons are not comprehensive, often change, or the entire development team is not very good communication.

Seven software defects may not be fixed for several reasons.

A: There is not enough time in the schedule, or not a software defect, or the fix risk is too big to fix, and the software defect is not reported correctly.
