The term ALCOA is an Acronym, which stands for Attributable, Legible, Contemporaneous, Original and Accurate. ALCOA was then expanded to ALCOA Plus (ALCOA+), by the addition of a few more concepts which are; Complete, Consistent, Enduring and Available.
Principles of ALCOA & ALCOA+
In order to understand the concept better, below we will break down ALCOA Plus and define each part of the acronym:1. Attributable
Attributable dictates that any data should be easily identified to the person who did the data collection, place of origin and the time of data collection should also be noted down. in the case of alteration of data, the person making the corrections should also be noted down.2. Legible
Legible data means the data can be easily read. This attribute should be ensured both in the short and long term, therefore the materials used in recording and collecting the data should be durable.3. Contemporaneous
Data recorded should be contemporary in nature. This dictates that the time of data collection should correspond accurately with the time of data recording. Any data collection should have a date and time, and the same should be ensured in the case of any later corrections.4. Original
In order to preserve the meaning and integrity of data, the original records should be preserved, meaning the material used should be durable. in the case of duplicates, the creator of the original records should confirm the authenticity of the copies.5. Accurate
For any data to be viable, it should be error free. In the case of any amendments, there should be accompanying documents to support the changes. The data should be complete and viable. Data quality must be maintained.6. Complete
When data is complete in nature, it means there is no deletion that has taken place from the date of the documentation. This includes any changes that have been made during the life of the data.7. Consistent
The data should be chronologically arranged, with time stamps included for any addition to the original data. Consistency should be ensured by applying various audits over the life of the data.8. Enduring
The material used to record the data should be in a manner that will last a long duration of time without losing the readability.9. Available
Data should be accessible whenever needed, over the life of the data. Availability ensures the data meets it's use, since it can be applied when the need arises.Frequently Asked Questions on ALCOA and ALCOA+
