Euro Quiz(1)
How many countries are there in the euro zone?
The answer is at Euro Quiz(2) below.

Still time to enter Eurotrophies competition
Small and medium-sized businesses have until October 15 to participate in the Eurotrophies competition.  This will reward companies which have been models in their preparation for the euro. The winners' stories will be widely disseminated so these companies can serve as role models for other businesses.
For more details, see

Accounting and Financial Software Issues for Small and Medium Sized Enterprises (SMEs)
This brochure [89Kb pdf] is in two parts. The first is intended for the advisers to small and medium sized enterprises (SMEs), although many managers will find the document useful to them. The second is designed as a leaflet which can be printed separately and handed to the clients of advisors or others wishing to distribute information to help companies with the change to the euro. I was closely involved in the production of this guidance note, which will help many users of mainly packaged software who do not need individual consultancy for a systems review or a euro project audit.

Why is database wrapping a 'dangerous IT solution'?
This has been a topic of great interest in our euro conversion training courses. The problems of "vertical" and "horizontal" rounding errors should be more widely known. The Association of British Insurers (ABI) provides guidance on this at

Quarterly review of the use of the euro
The take up of the euro is still very slow and is regarded with some concern. "Experience shows that the results of all the sample surveys carried out on the preparations for the euro tend to be overstated."

Are you ready for the euro?
(If you would prefer to read this call in French, German, Italian, or Spanish, let me know and I'll send it to you. This is a survey questionnaire from FEE that I am forwarding to readers on their behalf)

Concern is growing that preparations for the euro are falling behind and that some companies do not appreciate what they need to do and by when.  Having a clear understanding of the true situation is very important. FEE will use the information from this questionnaire to encourage national governments, the European Commission and the European Central Bank to make more information available and to clarify issues over which there is misunderstanding or uncertainty. No information about individual companies will be published.

The questionnaire is available on the FEE web site in English, French, German, Italian and Spanish. The questionnaire has only 9 questions. It takes about 2 minutes to load and a further 3 to complete. All you have to do is click to make yo

Euro Quiz(2)
Answer to Euro Quiz(1): It depends on what you count as the euro zone. Currently, there are eleven countries (BAFFLINGSIP) with the euro as their national currency, thus fully in the eurozone. There are twelve countries in ERM2. Greece was judged to have met entry criteria on 20 June 2000 and will join the eurozone on 1 Jan. 2001. Now for a follow up question:
What is the fixed conversion rate for the Greek Drachma?
(The answer is at the end of this document. If you know this and are not Greek, you have achieved what John Downe (IBM's Mr Euro) calls "anorak" status, roughly equivalent to the USA "geek".)

Hack Watch
The recent access to 30,000 accounts on the ISP (reportedly by a 17-year old) has brought this to the fore in Ireland. A sceptical, not to say dyspeptic look at the embarrassing side of the Internet in Ireland is John McCormac's The pun in the title is that not only does he report on computer, satellite/cable and smartcard systems hacking but he also satirises media hacks, or journalists with a less than desirable grasp of the facts.


Internet Features

Not that Eircom needs that much bad news when it can generate enough itself. Eircom has blocked mobile users from accessing data services through special, low rate Internet phone numbers, the 1891 numbers. This could be just another reason to avoid WAP (Where's Any Point?).  Old skills for maximising information density had been threatened by Internet bloatware, graphics, and multimedia. The challenge of the 4x40 character screen means that they are coming back.

Equally, the "old economy" skills of customer service and making profits which had been threatened by dot-com upstarts, are coming back into fashion with the demise of and, and delays in IPOs as reality sets in. Yes, it was fun while it lasted, but the shareholders paid the price of funding the information age equivalent of perpetual motion machines (which output more energy than they input). The technology is not the point; delivering what the customer wants is. On a small scale, for example, some companies take advantage of the preference of 18-24 year olds for SMS messaging to use that technology to deliver instant updates on the availability of requested apartment accommodation.

The European Union directive on Electronic Commerce came into force on 17 July. It includes provisions covering the exemption of ISPs from liability for content; transparency requirements for senders of unsolicited commercial communications ("spam"); and information requirements for traders using web sites. The Directive is available at

Web Site Design
Our own page of "Top Ten Mistakes of Web Sites" describes these common faults:
1.      No consistent message
2.      Not respecting user's concerns
3.      Lack of promotion
4.      No closure and followup
5.      Not providing a feedback method
6.      Visual fatigue
7.      Being too demanding
8.      Making navigation confusing and unclear.
9.      Being static and boring
10.     Not learning the culture

How do you think our web site rates on those criteria? Feedback is welcome! customers give Jakob Nielsen's book top marks in customer reviews. "Designing Web Usability: The Practice of Simplicity" by Jakob Nielsen, whose web site is Here are links for the book at Amazon in USA, UK, Germany, France, Canada, Japan.
