Acronyms

Engineering commonly has a lot of acronyms, often referred to themselves as TLAs (Three Letter Acronyms), rather helpfully. When you first join an engineering project the shear number of these acronyms can be confusing, frustrating and hindering, however, it would be near impossible to just stop using them overnight. As such, we've created a list of acronyms and abbreviations that we often come across and use to try and help our team members and other teams; as well as anyone else who's interested!


The following list will be updated reguarly as we come across new acronyms. If you think any are missing, let us know through our Facebook page or the Contact Us form on our website.
