I'm saying architecture is just one way of changing an organization. Other ways of changing an organization, separate from anything technical, might include changing people's schedules or vacation policy, or who you hire, or where, or how. Another would be how you store parts, make orders, assemble products. Or starting work in an entirely new industry.

Maybe you work at a company that sometimes works with the government. As a result, the whole company might develop a hiring process which is very slow, very detailed, and excludes certain people from being hired. But probably only a very small number of employees actually have to conform to those government requirements. You can apply them to all new hires "for simplicity", but it makes it harder to hire for non-government positions. So changing how you hire, to make it easier and faster to hire people of a wider background, benefits your organization. If your org can't easily make those changes, it will be disadvantaged.
