One of the biggest time sinks and "velocity" killers in BigTech, and sometimes also in MediumTech, is the need to get approval (sometimes multiple people's approvals) for absolutely everything. Often, approvers are among the most senior, busy people in the company, and "approving a dozen things" is not even top 100 on their list of things to do today. There are people who spend >75% of their time just "chasing" approvers and reminding them to please, please, please approve my Thing X so we can launch Product Y on time!
