What is progress? Are you sure that was greenfield?
I think the OP meant projects that required long investments without immediate returns. For instance, a platform migration that requires many components to be finished before it can even be tested. Or, real greenfield, like a new product venture with a unproven customer thesis. The kind that requires months of work before you can go to market and validade... How do you report progress? Components built, percentage completed? Without something a user can drive or a seller sell, that's not progress... It's just speculation.
