When starting at a job / project get to know the main acronyms for your work. E.g.
IFC – Issued for Construction
WAE – Work as Executed
Make a list of the main acronyms that relate to your project, program, or company.
A company or department wide list should be available in the intranet for all employees.
A project specific list (or a condensed list that covers most common acronyms) should be made available for each project member.
This should also be available on the intranet, stored by project.
Make sure they are easy to find. Not a spreadsheet that is in a sub-folder of a sub-folder etc.
