There is a half truth to code being the easier part.

In order to reduce the complexity of eventually coding something, you use modeling and code probes to validate the business model and then write the code.

This has been around since the days of batch programming and evolved through domain driven design principles.

The reality is the business can’t see that so they don’t invest in it and have no patience for it.

Agile wasn’t embraced because it was better. It was embraced because it was cheaper and faster.

Planning and modeling are the levers of complexity.
