Takeda Osaka replaced paper batch records with an eBR platform for three commercial biologics products — and paid down years of review-by-exception debt.


Paper batch records at the Osaka campus were averaging 340 pages per lot and driving a QA review backlog of nearly two weeks at peak. Right-first-time on batch records sat around 71 percent, and every audit surfaced observations tied to legibility, contemporaneity, or transcription errors.
The team defined a lean eBR data model per product, ran a structured user acceptance testing programme with shop-floor operators, and staged the rollout product-by-product. A change management workstream ran in parallel, retraining QA reviewers on review-by-exception and rewiring downstream release workflows.
Review lead time dropped from thirteen days to under two, right-first-time climbed above 96 percent, and the last two regulatory inspections closed with no data integrity observations. The eBR platform is now being extended to two additional commercial products.
We ran user acceptance testing with actual shop-floor operators — not managers or IT — and iterated the UI three times based on their feedback.
The unlock was making the eBR faster than paper for the common case. Operators stopped seeing it as a compliance burden once they realised it saved them 40 minutes per lot on data entry alone.
Modelling the review-by-exception logic. Paper batch records are reviewed page-by-page; eBR only surfaces the exceptions, which means the system has to know what "normal" looks like for every parameter.
We spent three months building the exception library with QA reviewers before the first product went live. Every subsequent product plugged into the same library.
The job shifted from checking every entry to investigating exceptions. That required a real retraining programme — QA reviewers had built decades of muscle memory around page-by-page verification.
We paired every reviewer with a senior colleague for their first month on eBR. By month two, review times had collapsed and everyone was confident in the new workflow.
A 340-page paper record is not a document. It's a two-week bottleneck disguised as compliance.
