Does your organisation have a style guide? This is a document that sets out standards for written communication. It could cover preferred spellings, rules for capitalising words, lists of words and phrases that should be avoided, etc
If your organisation has one you should, of course, use it.
If your organisation doesn’t have a style guide I suggest you find one online that you like and follow it so that at least your documents will have some consistency.
News outlets are a good source of style guide. Do a web search for your chosen news outlet + style guide.
If you are willing to invest some money in improving your writing then I recommend ‘Elements of Style’ by Strunk and White. It emphasises the importance of clarity and brevity in writing.
As Dorothy Parker wrote:
“If you have any young friends who aspire to become writers, the second greatest favour you can do them is to present them with copies of ‘The Elements of Style’. The first greatest, of course, is to shoot them now, while they’re happy.”
