Development to staging to production process
This is a good start, drupal 8 has inbuilt configuration import/export functionality: https://www.drupal.org/docs/8/configuration-management/managing-your-sites-configuration 

You could automate/speed up the process abit by adding the exported configs to your git repository and using drush to create them

But its especially: do an export on your dev which will generate config files all zipped up. Then do an import on production which allows you to review the changes before actioning them
