Edward Tufte: Books - Essay: The Cognitive Style of Powerpoint:
"Alas, slideware often reduces the analytical quality of presentations. In particular, the popular PowerPoint templates (ready-made designs) usually weaken verbal and spatial reasoning, and almost always corrupt statistical analysis. What is the problem with PowerPoint? And how can we improve our presentations? "

SocietyGuardian.co.uk | Society Guardian | Bureaucratic jargon:
"To write effectively, we need to know three things: why we are writing it; what we want to happen as a result of our writing; and who we are writing for. If the target audience includes the public then this means using shorter sentences (average about 15-20 words), shorter words and avoiding jargon. So don't write in plain English henceforth - write in plain English from now on."

There is no shortage of helpful advice to authors. My book, The Plain English Guide (OUP, 1995) distils it into 20 guidelines. To summarise them:

· Use appropriate language - not too pompous, not too colloquial.

· Write sentences of reasonable length - 15-20 words on average.

· Favour active-voice verbs.

· Don't smother verbs beneath noun phrases: so 'We prepared...' not 'The preparation was undertaken by us...'

· Use personal reference words.

· Use a main heading. In long letters, use subheadings too.

· Use vertical lists to split up complex information.

· Use a top-heavy triangle structure, giving the big news early in each section. Alternatively, use chronological order if this will help the reader.

· Use tables, charts and graphs to help the reader understand.

· Reread your letter before it goes out. Revise it. Then revise it again. You don't have time, but you have to make it.

· If you've an important writing job to do, arrange your environment to suit you. This might mean booking a writing room in the office, or working at home.

Finally, remember the words of Lord Denning, the leading judge, in the 1980s: "It is better to be clear and brief than to go drivelling on."
