When developing the ACRN, which letters should be avoided?

In the context of developing the Acquisition Contracting Research Number (ACRN), the letters that should be avoided are O and I.

This avoidance is primarily due to the potential for confusion that these letters may create when interpreting the ACRN. The letter 'O' can be easily mistaken for the number '0' (zero), and the letter 'I' can be confused with the number '1'. This is especially relevant in documentation and data entry processes where clarity is crucial to ensure accuracy in contract management and reporting.

Maintaining a standardized set of characters that are distinctly different helps to minimize errors in communication and documentation, which is essential in contracting processes. Using letters that are easily distinguishable enhances the efficiency and clarity of record-keeping and reduces the risk of misunderstandings in contract interpretation. Thus, avoiding O and I is a best practice in ACRN development.
