Software defect classification standards, how the defect level of software should be classified

Did you find the answer? I'm looking for it too.

The defect classification method of software is as follows:

Once a software defect is discovered, it is necessary to try to find the cause of the defect, analyze the impact on product quality, and then determine the severity of the software defect and the priority to deal with the defect.

The consequences of various defects are not the same, some are simply inconvenient, and some can be catastrophic. The more severe a general problem is, the higher the priority it will be to deal with, which can be summarized into the following four levels:

1. Fatal error: causing system crash, crash, and endless loop, resulting in database data loss, wrong connection to the database, loss of main functions, and lack of basic modules.

2. Serious errors: partial loss of the main functions of the system, database saving and calling errors, loss of user data, and the test of other functions of the function menu that cannot be used but does not affect Zheng Xiang. The function design is seriously inconsistent with the requirements, the module cannot be started or called, the program restarts, the automatic exit, the call conflict between the associated programs, security issues, stability, etc.

3. General error: the function is not fully realized but does not affect the use, and the function menu is defective but does not affect the stability of the system.

4. Suggestion problems: interface, performance defects, suggestion problems, solutions that do not affect the execution of operation functions, solutions that can optimize performance, etc. For example, typos, non-standard interface format, overlapping page displays, hiding what should not be displayed, unclear descriptions, prompts.

Missing, untidy text arrangement, incorrect cursor position, user experience.

Feel bad, you can optimize the performance of the program, etc.

1) Defects in product design. That is, due to design reasons, the product has an unreasonable danger of endangering personal and property safety. For example, if a hot pot using a gas stove is unreasonable in structure or safety factor design, it may lead to normal use, and the product is a product with design defects.

2) Defects in the manufacture of the product. That is, due to product processing, production, assembly and other manufacturing reasons, the product has an unreasonable danger of endangering personal and property safety. For example, the production of children's toys does not use safe soft materials in accordance with the design requirements, but uses metal materials with sharp angles, which endangers the personal safety of children.

The product is defective. (3) Due to a defect in the notice (also known as an indication defect or an explanation defect). That is, due to the characteristics of the product itself, it has a certain reasonable risk.

For such products, the manufacturer shall add necessary warning signs or warning instructions on the product or packaging, or in the product manual, to inform the precautions for use. If the manufacturer fails to add warning signs or warning instructions and indicate the precautions for use, resulting in the product causing danger to personal and property safety, the product is a product with notification defects. For example, if a gas water heater is dangerous to the user under certain conditions, the manufacturer should inform the precautions for safe use in an appropriate manner, such as the water heater must be installed in a place with air circulation outside the bathroom.

If the producer does not explicitly inform the product, it can be considered that the product is unreasonably dangerous. If the product has any of the above defects and causes personal and property damage to others, the manufacturer shall be liable for compensation in accordance with the law. 2. What constitutes liability for product defects?

Product defect liability refers to the civil legal consequences that should be borne by the manufacturer, seller or other person who provides defective products and causes property or personal injury to others. There are three elements for the composition of product defect liability: (1) Product defect The existence of product defects is a necessary condition for the constituent elements of product defect liability.

2) The existence of the fact of damage If the product is defective but does not cause damage, the issue of liability for product defects does not occur. In other words, liability for product defects arises on the basis of the existence of the fact of damage. This damage includes both damage to property and damage to persons.

The victim may be either the purchaser of the product, the user of the product, or a third party who is neither the purchaser nor the user. (3) There is a causal relationship between the damage and the defect of the product, that is, the damage is caused by the defect of the product, not by others using the product as a tool to commit infringement.
