7.COCOMO 2 allows more and more detailed evaluation and preparation with the development progress, of which three levels are the third level of early prototype level, early design level and post-architecture level style.

8. The required activity development software system is not specification, design, inspection and evolution.

9. The software maintenance process includes five stages: change request, consequence analysis, system release plan, change implementation and system release.

1. What is software structure design?

Logo constitutes the subsystem design flow and subsystem framework control of the system, and communication is architecture design.

According to this book, there are three types of software maintenance. What do you want to tell them? Maintenance of repairing software defects. Adapt to software maintenance in different operating environments. Add, maintain or modify system functions.

3. The algorithm cost model is a mathematical function of product, personnel and process attributes, and its value is estimated by the project leader. Give the equation about effort and explain the meaning of parameters.

Effort = A * size B*M

A is an organizational dependence constant, b reflects the unbalanced efforts of large projects, and m is the product, process and human attributes reflected by multipliers.

4. Explain why software changes are inevitable. When using, new emergency software is needed.

Changes in the business environment must be repaired. The error must be adapted to the new equipment.

Performance or reliability may have to be improved.

5. What is a stress test?

Running a system that exceeds its maximum design load.

6. What is equal division?

Input data and product results usually belong to different classes, in which all members of the class are related.
