A document-processing demonstration often uses a clean sample. Everyday inputs may contain blurred phone photos, missing pages, sideways scans or text embedded in images. An OCR readiness review asks whether text can be recovered with enough evidence for the intended workflow, before an agency builds automation around it.

SECTION 01
Bring difficult samples to discovery
Include digital PDFs, scans and phone photographs that actually occur in your process. Note language, page counts, handwriting, tables and recurring scan defects. Use permitted or synthetic samples and avoid sharing unnecessary sensitive data. Ask the agency to report unsupported inputs rather than quietly removing them from the evaluation.
Microsoft's OCR documentation distinguishes supported formats and input constraints. Those constraints vary by selected product and version, so the brief should require a current compatibility check, not a promise to read every file. Upload controls also matter: OWASP recommends validating file types and limiting uploads rather than trusting the filename alone.
SECTION 02
Illustrative example: a cropped delivery receipt
Imagine a warehouse sends a receipt photo with the left edge cut off. Most item descriptions are readable, but the first characters of the delivery reference are missing. Guessing the reference from another record would make the extraction look complete while hiding an input problem.
A useful workflow highlights the uncertain reference, shows the original image and asks for a replacement photo or authorized manual entry. The replacement is linked as a new source version. If page two arrives later, it joins the correct document rather than becoming an unrelated record. The test set includes both the original poor scan and the corrected version.
SECTION 03
Define the output of the review
Request a sample inventory, known failure categories, supported input list and acceptance cases for important fields. Separate OCR mistakes from later interpretation errors: a correctly read amount can still be assigned to the wrong column. Record whether coordinates or page references are available for showing evidence to a reviewer.
Compare improving capture instructions with buying more complex extraction. A simple rescan prompt may be more dependable than elaborate reconstruction of unreadable material. At handoff, demonstrate rotated pages, missing pages, duplicates, locked files and oversized uploads. Agree who handles exceptions and how the operator knows that every required page has been received before the next action proceeds.
SECTION 04
Frequently asked questions
Can AI recover text that is not visible?
It may guess, but a business workflow should not treat a guess as source evidence. Request a better scan or route the field for authorized review.
Do we need OCR for every PDF?
No. Some PDFs already contain usable text. The implementation should inspect the document and choose an appropriate path while preserving source references.
Should we replace all paper forms first?
Not always. Compare targeted capture improvements with extraction complexity. A clearer form or better photo instruction can resolve a recurring problem without a complete process replacement.
