Factors Affecting software quality management

The features of the software and the current software development model make it impossible to completely avoid quality defects hidden inside the software. There are many factors that affect the software quality:

1. Vague software requirements and changes to software requirements fundamentally affect the quality of software products

Software is a complex logical entity with poor visibility, unlike any other manufacturing product. One factor that makes software quality hard to grasp is software requirements. It is a very important task to determine a requirement. In the early stage of software development, it is the basis for subsequent development, it is also the basis for the acceptance after the software development is completed, and it is also the starting point for the construction period and Development Cost Estimation. suppliers and users naturally care about it in ten minutes. But in fact, software requirements are invisible and often unclear. Software users often do not understand their own needs, or do not understand their own requirements for the software, or there may be situations where the user's requirements change. This phenomenon will certainly bring a lot of difficulties to the software development work, it will certainly bury the hidden danger of software quality defects.

2. Manual development is hard to avoid errors

At present, most software development work is still manual, but developers need to concentrate on intensive intellectual work. Errors may not be completely ruled out for such complex, meticulous, and poorly visible tasks.

3. practical difficulties in Software Quality Management

Many software quality indicators have not been quantified. Software development administrators are often more concerned about the cost and progress of project development, because the cost and progress are obvious and easy to measure, while the software quality is completely different.

At present, the product quality responsibilities of many software institutions have not yet been implemented. If the software development administrator is not responsible for the number of errors in the delivered software, then they must have little enthusiasm to control the quality of the development, not to mention that it is not easy to ensure the quality, it is expensive to ensure the quality.

Non-standard development habits are hard to be corrected. Obtaining high-quality software products mainly depends on the people involved in the development. However, the habits of software developers cannot be changed once they are formed, and their behaviors cannot be controlled.

Communication between personnel is prone to problems. Many software engineering projects require the participation of several or even many technical and management personnel. Information and ideological communication between them is necessary and frequent at work, but problems often occur in mutual communication. If different understandings and misunderstandings about the problem cannot be eliminated in a timely manner, the root cause affecting product quality will surely be buried.

The flow of personnel in the software project team will affect the product quality. It is difficult to avoid the flow of personnel in the software project team. Facts show that for organizations that have not yet established mature software processes, the departure of those who leave from the software project team, especially the backbone forces, will take away their thoughts, technologies, and experience, this is a loss, and the quality of project development will also be affected.
