Understanding of the concept of "quality"
2022-06-24 08:16:00 【Multi surveyor 111】
ISO The definition of quality is “ The extent to which the product or service meets the needs of customers ”, It's always hard to understand . Recently I saw Weinberg's 《 quality . Software . management 》, Have a deeper understanding of the concept of quality .
Weinberg Think that quality is relative : A software product that the user thinks can be completely passed , Another user may think that the quality is completely unsatisfactory . Different people will reflect different qualities of the same software product .
So every statement about quality is about someone / Human statement . On quality , First of all, it is necessary to make clear whose quality is aimed at . for example :
High quality is impeccable
This is true for bank users —— These defects may screw up the work of these users .
This is true for some executives —— They are blamed for the existence of these defects .

High quality is to provide many functions
This is true for some users —— They will benefit from these features at work .
This is right for marketers —— Those who believe that more features are more likely to sell .
High quality means high performance
This is correct for securities users —— Their work overwhelmed their computers .
High quality means high development speed
For some marketers , It's true —— They try to capture the market before competitors check it out .
High quality is high user friendliness
This is true for counter users —— They use the software eight hours a day staring at the screen .
The same is true for some older people —— Every time you use the software , They can't remember the details of the last time they used it .
In the project , If we want to improve the overall quality of our products , First, you need to identify all relevant users , That is, stakeholders , And have a comprehensive understanding of their respective needs , For example, the interface UI demand , test 、 Testable requirements for operation and maintenance . With operation and maintenance requirements 、 After sales service demand, etc . The user group is young people 、 Enterprises 、 Training institutions, etc , Need to consider targeted needs , It must be clearly determined before the product requirements review .
