Often we advice or design data architecture for projects.
There are many ways to build software products. We aim for the most simple data structures because as many fields, connection and integrations are added... everything becomes complicated anyhow - having a simple architecture can save you tons of time and effort managing complexity.
What it means is that in later stages of development, making a seemingly simple change can be simple, and not a month's work - reformulating the system to accommodate for it (because that situation hasn't been though of in the planning phase and the system build in a way that doesn't allow this change).
