Although depicted as a linear, sequential process, the process can be much more nonlinear. The steps serve as a guide to the activities you carry out and may run in parallel. Agreeing on definitions, modeling the semantics, and getting community endorsement can be very cumbersome, so working on a schema through repeated cycles (iterative) and starting small (incremental) may be more efficient than trying to be perfect and complete from the start.

and outreach
Below a schematic overview of how a timeline and how to involve your domain (see step 7) may look like.
How long this process takes depends on several factors, for example the capacity of your metadata taskforce, how well your domain is organized, what the scope is of your schema, how much modeling work has been done already in your domain, and how you work with your metadata taskforce. For collecting requirements and for reviewing you often have to give your domain some weeks to respond. It may be worthwhile to consider design (sprint) approaches where you block several days in row with your taskforce to work only on the model (see for example here) instead of spreading meetings over the months.
