You should make sure that terminology that is ambiguous or unclear is made clear with definitions.
This can avoid mistakes and reduce the time necessary to re-design.
- “Rail Overbridge”. Is this a rail bridge that goes over something, or is it a rail with a bridge over it?
- A Rail Overbridge is a bridge over the railway.
- A Rail Underbridge is a bridge carrying the railway and allowing a roadway, river etc. to pass under the railway.
You may have to get clarifications of definitions from you project sponsor for organizational specific terms.
Don’t assume all your team knows the terms.
