Why do we advocate quality-oriented project management?

As a project manager, I have always advertised myself as a quality-oriented project management advocate and professional. Why? It is also based on the experience of successful projects that you have done.
In TQC, the three elements of project management need to be balanced in project management, but they need to understand that they are not equal. Why? This is also caused by the characteristics of software projects. For details about the features of software project management, see Article . The delay and cost increase in software projects are largely due to quality, and system quality problems often lead to rework, rework in software projects has become a nightmare for the project manager. The direct consequence of rework is the delay in progress and the increase in costs. Of course, it will also lead to the frustration and frustration of the team members, which of course will affect the development efficiency.
Quality-oriented project management is the most economical in terms of schedule control and cost. This can be illustrated by statistics from industry project management experts. For software projects, costs mainly come from labor costs. Therefore, personnel efficiency, communication costs, process capabilities, and process accumulation are very important. In addition, our cost refers to the concept of total cost, not just the development cost. At present, this problem exists in many companies, and the development budget is well controlled. However, due to the neglect of quality, the rework cost of this project during implementation and maintenance is very high, or even re-development, this results in a decline in customer satisfaction and directly affects the overall cost and profit. In my personal experience, Q is the reason among the three, and T and C are the result. Therefore, to reduce and control costs, it is necessary to control and find the reasons at the source. Effective control and improvement of the Process Quality of software development often reduce rework, improve collaboration and communication efficiency, thus saving costs and shortening the construction period. If you are blindly guided by the progress and cost results, it will often lead to the progress and cost exceeding the plan, which is like seeking for fish.
Quality-oriented: the project manager needs to grasp the quality of the project from the heart, rather than simply negotiating with the customer to reduce the scope of the project. This approach is often the final disadvantage of the project team. We all know that the scope of software projects is hard to be clearly divided. This is also one of the major features of software projects. Construction projects can be described by the units of measurement recognized by everyone, customers often say that you give me three functions, four modules, and so on. The two sides of the conversation have misaligned their understanding.
The following data may explain the benefits of quality-oriented project management.
Average cost exceeds average progress Delay
Quality-driven 6.1% 4.5%
Progress-driven 10.3% 9.0%
Cost-driven 9.9% 15.9%
