How would you ensure that proper plans are installed for the creditors section which was been managed poorly in the future?

I'm not sure whether you have any options, but here are some of the ways you can ensure that proper plans are installed for the creditors section in the future:
1. Proper handing and monitoring of resources which includes systems, documentation, and procedures - this is very important, to take care of everything so that there are no mistakes
2. Finances must be reviewed correctly, either it is external or internal - unless you do this, you are facing a risk of losing yours, as well as creditors' money
3. Perform and conduct series of simulations before actual implementation - you need to know whether your changes will work before you actually introduce them
