Client Approval and the Backwards Waterfall diagram

Every step forward you take in a waterfall process, you’ll inevitably end up re-litigating decisions of the past. A designer, for example, must expect clients to renegotiate context and architecture through the designs, even if they may already have been ‘approved.’

It flat-out appears to be human nature. Your client, or anyone for that matter, will try to play by the rules of your process, but they will usually lack enough information to actually give informed approval. Despite this, they will give tempered approval in the interest of time, but also continue to gather more information so they can make up their mind(s) later.

The only time most clients will have a high degree of comfort giving final approval is on launch day when they simply can’t delay any longer.
