Given the success of Simplified Technical English (STE) and its adaptability, it was over time applied to various document types, and increasingly also in other (mainly technical) industries. In the aerospace and defence industries, safety, efficiency and readability are the main considerations for the use of STE. In many other industries, such as machinery, automotive, electronics, IT and medical equipment, another important consideration is to save on translation cost without compromising on translation quality.
Simplified Technical English (STE) rules describe sound writing practices
STE is an aerospace standard, or at least it started off as an aerospace standard. That having been said, out of those 65 writing rules, I couldn’t name a single one that is aerospace-specific. Take these STE rules for example:
- Do not make long sentences (maximum 20 words for procedures, 25 words for descriptive text).
- Do not use clusters of more than 3 nouns.
- Only use simple verb tenses.
- When you give an instruction, use the imperative/command form of the verb.
Well, most of us will have seen this kind of rules. We don’t like long sentences and Simplified Technical English tells us that for procedures or tasks there should be no more than 20 words in one sentence. For descriptive text we are allowed some more flexibility, and we need that, we have up to 25 words. Also English is a rather problematic language in that it allows us to just put any number of nouns into a cluster, and this makes it very difficult at times to see the relationship between the nouns in those clusters. For example ‘left engine switch’ can already be confusing, and difficult to understand, difficult to accurately translate.
If I say ‘left engine switch’, does that mean it is the switch for the left engine, or is it the left switch for a specific engine? So, do ‘left’ and ‘switch’ or ‘left’ and ‘engine’ belong together most directly?
In this case, the use of prepositions such as ‘of’, or ‘for’ will help to clarify this. Take the example of the ‘runway light connection resistance calibration‘. While it is common to see noun clusters made from several words in technical language, clusters that are too long will mean that your reader has to make his way through four modifying words to reach the main noun.
For technical writing professionals who are considering the option of implementing Simplified Technical English (STE) in their organisation, you now see that many of the STE writing principles are very valid for all technical documentation purposes.
One STE rule that can transform your technical writing skills
One valuable STE rule is the rule that I would consider the most important one: Only use approved words. This is where Simplified Technical English becomes really different from corporate style guides. Why? Because the STE language standard includes a core vocabulary (or general dictionary) of around 930 words that will let you write just about everything that you need for technical documentation, even for procedural information in general.
We find that roughly 95% of the words in the STE general dictionary can be easily adapted even for general banking, like financial aspects of banking information. The set-up of the STE standard is such that you can very easily adapt the STE to suit and cover your specific needs. It mainly entails additions to the dictionary which are customarily made, even for aerospace customers. Because even within aerospace, there is a lot of variation when it comes to vocabulary, terminology, especially when dealing with different systems on board an aircraft.
As a very simple example, one of our customers actually makes coffee machines. Now coffee machines seem to have nothing to do with aircraft. However, I think 98% of passenger aircraft actually have coffee machines on board, and they need their documentation in Simplified Technical English.
Now if this coffee machine happens to be in an office, or in a medical practitioner’s practice, or in a cafeteria, would it really require documentation that is all that different from the documentation on board an aircraft? No.. If anything at all, we just restrict the rules a little bit less. Aerospace tends to be a little bit more restrictive, we just relax the rules a little bit for other industries.
