Revisions can be a time-consuming part of the design process as it means you must review the work then write up and share these desired revisions, which then must be communicated and worked on. A single revision cycle could be fast or take a long period, it really is unknown. Ideally, we will make as many revisions as needed to satisfy the client fully. However, if an excessive amount of revisions is needed, then there has been a breakdown in communication at some point. Ultimately, we would work this on a case-by-case basis, but this is more of an edge case than normal operating procedure. As mentioned, we have a long history in the design industry so we can fill in the blanks a lot of the time and so typically revisions should rarely ever go over 3 total for any one item.
