Providers like Hurix Digital and Codemantra make interactive QA and validation a first-class part of delivery, but governance and source spec discipline still determines whether those checks can be repeatable.
Assuming interactive behavior will survive conversion without stricter source structure coordination
Hurix Digital flags that interactive logic needs stricter source structure coordination, and governance discipline impacts whether device rendering matches expectations. Codemantra also calls out that custom interaction logic needs clearer specs and iteration to stabilize behavior.
Treating navigation generation as a byproduct rather than a validated deliverable
ebookconversion.com and Aptara both emphasize EPUB navigation generation and navigation correctness to reduce reader landing issues. Codemantra ties navigation correctness to interactive validation, which helps prevent fixes that only address visuals.
Letting widget timing and media synchronization vary without conversion QA targeted to device regressions
Aptara targets device regressions in its QA for interactive widget consistency across packaging and navigation generation. Map Systems also warns that timing constraints and media synchronization can require tight constraints on timing to keep behavior stable.
Overestimating throughput when input formatting cleanup is inconsistent
