ALCOA+ in practice: nine words your records have to live up to

ALCOA+ is the rare acronym that survived because it is genuinely useful. It compresses the whole of data integrity into a checklist you can hold against any record, paper or electronic, and instantly see where it bends. The trouble is that most people meet it on a slide, nod, and never apply it to a real record again.

So apply it. Take one record your team produced this week, a chromatogram, a batch record entry, a cleaning log line, and walk it through all nine words.

The original five

• Attributable. Can you tell who created this, without asking anyone? Shared logins fail here, instantly and completely.
• Legible. Readable today and in ten years. For electronic records this means the rendering software survives too, not just the bytes.
• Contemporaneous. Recorded when it happened, not at the end of the shift from memory. Backdating is the cardinal sin; honest timestamps are the whole point.
• Original. The first capture, or a verified true copy. A printout of a dynamic record is not the record. The audit trail behind it is part of the original.
• Accurate. Reflects what actually occurred, with corrections that do not obscure the first entry.

The plus that does the heavy lifting

The four added words, complete, consistent, enduring and available, are where electronic systems earn their keep or fail. Complete means including the failed runs and aborted sequences, not just the result you reported. Consistent means timestamps in sequence and one time zone strategy across systems. Enduring means the record survives system retirement: migration, archival, retention. Available means an inspector asking for a 2019 record gets it this week, not after a vendor support ticket.

The honest conclusion: data integrity is not a feature you buy. Systems can make the right thing easy and the wrong thing visible, but the culture decides whether anyone looks. A perfect audit trail nobody reviews is a very expensive way to store guilt.
