What is the basic principle of software engineering?

1, strictly managed by phased life cycle plan;

2. Insist on stage review;

3. Implement strict product control;

4. Adopt modern programming technology;

5. The results should be clearly reviewed;

6. The staff of the development team should be few but fine;

7, admit the necessity of continuous improvement of software engineering practice;

Extended data

(1) Applicability: How easy it is for the software to meet the needs of users under different system constraints.

(2) Effectiveness: The software system can make the most effective use of the computer's time and space resources. All kinds of software take the time/space cost of the system as an important technical index to measure the quality of software. On many occasions, the pursuit of time effectiveness and space effectiveness will be contradictory, so we have to sacrifice time effectiveness for space effectiveness, or sacrifice space effectiveness for time effectiveness. Time/space tradeoff is a common technique.

(3) Modifiability: The system can be modified without increasing the complexity of the original system. It supports software debugging and maintenance, which is an unattainable goal.

(4) Reliability: It can prevent software system failures caused by imperfect concept, design and structure, and has the ability to recover software system failures caused by improper operation.
