Terraform and Infrastructure as Code Best Practices

We use terraform at work, and because of the process it's a huge pain to work with.

For example, to change permissions kinesis stream, Dev has to to create a PR in the tf config repo and wait for someone in SRE team to merge and apply the PR.

If I intend a single line change, I have to wait till Friday to get it noticed by SRE in a meeting. Then depending on the availability of his time, they would make those changes in upcoming month. God forbid if I make a typo or something.
