What does everyone use to manage ECOs (Engineering Change Orders)? Native built-in functionality, or SuiteApps?

We use NetSuite natively for ECOs, however, it's not good. My company is having issues with the quality of ECOs Engineering Change Orders in NetSuite. My engineers describe it as 'no better than Notepad'. I can't help you, but want to know what any other company is using. We started researching Arena PLM, as they have a SuiteApp.
