In 2c8 Apps, you can manage changes in models using version management and spreading the responsibility using the maintenance roles Modeler, Reviewer, and Approver. Maintenance of models is made in both 2c8 Modeling Tool, 2c8 Lite, and also the web app 2c8 Approve.
You can ensure quality by letting your models go through the maintenance flow, where models are edited by the right users, reviewed by the right users, and approved by the right people within your organization. You can then choose only to publish approved versions of models and ensure that the information reaching the end-user is accurate.
If you want to start working with the maintenance of models in 2c8 Apps, you should start by selecting maintenance roles for your models.
