Rulespeak (2010): “Definitie: RuleSpeak® is een verzameling richtlijnen voor het formuleren van bedrijfsregels op een bedrijfsvriendelijke en precieze manier. Het is geen taal of syntax maar eerder een verzameling voorschriften voor Nederlandstalige formulering van bedrijfsregels gebaseerd op ervaringen in de praktijk.

Bedoeling: • Het vergroten van de helderheid en consistentie in het communiceren van regels tussen mensen uit de bedrijfspraktijk of als eisen (requirements) voor de ontwikkeling van IT systemen.

• Het effectief verkrijgen, verwoorden en behouden van bedrijfskennis en criteria om beslissingen te nemen.”

NO SILVER BULLET

(Brooks, 1987 - IEEE Computer)

Can you imagine having no traffic lights or signs or any other way of keeping cars and people apart? The results would be dangerous chaos, right?

Well, they have a lot a faith in human nature in the small Dutch town of Drachten. Its main intersection is a busy place, where cars and trucks compete with people on bicycles, and others on foot. The normal civic response - here and elsewhere - has been to put in more traffic lights, divide the roadway into lanes - control things. But the response in Drachten has been the opposite - they took the controls away.

A funny thing happened. The accident rate around the intersection went down - way down, from more than eight a year to fewer than two.

"We wanted to appeal to social behaviour, people's own behaviour and their responsibility," says Nieske Ketelaar, Drachten city councillor………………

No signs or lights - but fewer accidents?
