Global cost of poor HCD in IT

Roger Sessions has a great post on the cost of IT failure. His estimate, including direct costs and lost opportunity costs, is USD 6.18 Trillion. Almost enough to make a banker interested.

How much of this could have been prevented by applying Human Centred Design , usability assurance? Perhaps half?

For the UK, his figures (in B USD) are
GDP 2260
Cost of IT failure 200

If usability represented about 10% of IT spend, then in the UK it would be a USD 6B business. So, at say 1.5 dollars to the pound, and GBP 150k per usability person (including overheads etc.) that would be 28,000 usability people in the UK. Some room for growth there, I suspect.

His numbers come from WITSA. I didn't find the document. A google search of the site found 1 reference to the word usability (not a particularly focused reference) and none to ergonomics.

Products, systems and services

The life cycle perspective of systems engineering has long considered the relation between system products and services. An example given by Stuart Arnold is of a bridge; it changes from being a civil enginering project to being a traffic engineering service.

Ergonomics has considered features beyond the central 'product' for a long time. John Hughes at IBM looked at the experience of receiving a Selectric typewriter, from how to design the box to be picked up safely, and unpacking the typewriter etc. (written up in Design Studies, but not showing up in the Scirus search - so much for peer-reviewed credibility).

Don Norman has written a nice piece on these lines called Systems Thinking: A Product Is More Than the Product. It covers packaging and support; very different in the eyes of the vendor organisation, but both part of the experience so far as the user is concerned.

Quality = ease of use

Pure Digital's Simon Fleming-Wood(Flip video camera) defines quality entirely in terms of ease of use. He says "We will always prioritize accessibility over features".

This appears in the Wired article 'The Good Enough Revolution: When Cheap and Simple is Just Fine'.

The article says much that is not new. Which? magazine has been banging on for a long time about how people like VW Beetle (original not retro) technology and dislike 'featuritis'. However, it has some interesting observations about the potential for mini-clinics, which I suspect that the current NHS plans will not realise for us in the UK

We need some tools to be able to relate Quality In Use to price point; the usability community has kept itself 'pure' by ignoring the framing that price brings.

Service from ISPs and mobile phone operators. Do we just give up?

Quality of service has not been a factor in OFCOMs regulation of mobile phones and ISPs. Accordingly, this has not been a factor of concern for most providers.

From a user point of view, it is almost impossible to know what the provider would be like until you are tied up into a contract. There is advice from ADSLguide for broadband, but it is still hard to decide. From my own experience, there are now no mobile phone operators with decent customer service, following the offshoring and collapse of the once-wonderful Virgin Mobile.
OFCOM has looked at Quality of Service, and set up a comparison website, which seems to be completely useless.

OFCOM says that price is the most important factor, but recognises that Quality of Service is also important. Price is something that can be compared before a purchase decision, while Quality In Use is much harder to get information on until it is too late.

In June, OFCOM decided to withdraw topcomm.

Does this mean that it is official that mobile and ISP service will always be cr*p? Or, is there hope that OFCOM might be interested in hearing about Human-Centred Design, Quality In Use, and the established means that exist for providing assurance?
