House Decoration and software development

I suddenly found that the decoration and software development were so familiar that I wanted to implement the software development process into the decoration process. I hope that the decoration process will be improved three months later, my decoration effect can better meet the needs of customers (me.
It took three days for the decoration plan to first let the designer understand the basic situation of the House and our basic requirements, and then negotiate with each other to create a plan, that is equivalent to the outline design of software development. During the design process, I always recommend designers to communicate with us more, so that we can always participate in the design process. This is called Agile practice.
After completing the outline design, the designer spent nearly two weeks on the design of the facade (architecture design) and the construction drawing design (detail design), during which he went to the decoration company to talk about the preliminary design, the designer will explain the drawings one by one (demo ?), I have made some suggestions and made modifications (feedback) based on our suggestions during the design so as to enter the next design phase (iteration ?), Haha implements agile development throughout the decoration design process.
Coding ?) During the construction period, the customer (I) should visit the construction site frequently (this is also a demo), then make suggestions (feedback), and then modify (refactor? Change Request ?), Haha
The design is coming soon. I hope I can truly implement agile development into the decoration process!
