One option is to do 0/1, to measure whether the Initiative is done or it's not.

Or you can do 0 to 100%. This is useful if it's a multi-step process or larger project and you want to track the progress towards completion. This progress is often subjective and that's okay. Here, the qualitative updates you provide via your progress update comments to provide context.

Alternatively, if you had an Initiative to write 5 blog posts, you can track it 0/5 to keep track of individual outputs.
