SOFT TESTING 3 July 2002 by Patrick O'Beirn

The following scenario was described in an online tutorial I came across recently:

Everything you buy, you have to support -- or hire someone else to support. That's the problem with buying and deploying lots of stuff: it all needs attention. To make your support dollars effective, there are a number of things that you need to know. For example, you must know all that you have in your infrastructure: laptops, desktops, servers, PDAs, minicomputers, mainframes, communications networks, routers, switches, business applications, and messaging applications.

A Web service is a programmable entity that provides a particular element of functionality, such as application logic, and is accessible to any number of potentially disparate systems through the use of Internet standards, such as XML and HTTP.

As the next revolutionary advancement of the Internet, Web services will become the fundamental structure that links together all computing devices.

Variation in your environment -- whether furniture, heating, air-conditioning, transportation, or your technology infrastructure -- is expensive. But although there are great savings embedded in standardized environments, the whole is fraught with emotion. Nearly everyone in your organization will have an opinion about what the company should do about operating systems, applications, hardware, software acquisition, services, and even system development lifecycles.

One message that comes through loud and clear from this month's CBR on Web services is that we (i.e., the IT industry) are not yet at all sure what we mean by these two words. Maybe that's not surprising. It is the latest buzz phrase, and judging from the data presented in the articles that follow, everybody is piling on this bandwagon (we may not know what it is, but most of us are pretty sure we're doing it). Buzz phrases are vague by nature, and when people start piling on, definitions usually get hazier.
