The reality of Web services

Cringely's Law, named for former InfoWorld columnist and author Robert X. Cringely, says that technology changes far less in the short term than we expect but that it has a far greater impact in the long term than we realise. That observation can certainly be applied to Web services technology, and it could also be applied to how Web services will change the consulting landscape, according to Brent Sleeper, a consultant and partner with The Stencil Group.
Sleeper said. The emerging Web services market will affect the consulting industry, especially in terms of the type of work consultants are asked to provide. The promises of cheaper solutions that allow extreme agility between systems will eventually become a reality. And the greatest innovations will likely come from a handful of small, pioneering software firms.
Sleeper has three suggestions for how consulting firms should prepare for the market changes Web services will bring:
- Start experimenting with today's Web services capabilities.
- Continue to invest in developing your firm's strategic business expertise.
- Aggressively pursue relationships with up-and-coming software vendors.
Get your hands dirty: Use today's Web services technology
Despite the fact that the technology is at an extremely early stage in its development, it's critical for consultants to actively experiment with Web services technologies, Sleeper said.
"There are still a lot of missing pieces, but I think getting some hands-on experience with what works and what doesn't is a benefit whenever there's a technology change," he said.
And while there may be a gap between what customers expect and what Web services technology can deliver, for the most part customers have realistic expectations and see their initial implementation as the first step in an incremental, gradual rollout.
Examples of current projects
Sleeper said he's seeing small-scale pilot projects that utilise Web services and demonstrate the technology's efficacy, as opposed to the replacement of entire systems.
As part of The Stencil Group's Web services market research and analysis, Sleeper has interviewed project teams at several organisations engaging in early Web services implementations. The kinds of projects he's seen fall into two categories:
- Those that solve specific technical challenges that have been nagging problems
- Those that deal with the automated integration between large organisations and their smaller trading partners
"Using SOAP to connect those systems and pass data back and forth is kind of a mundane [Web services] application, but it's also solving a real problem today," Sleeper said. "The organisation sees that as a building block for assembling more sophisticated systems on top of the basic communications protocols."
As an example of an automated integration project, Sleeper pointed to Eastman Chemical Company, a chemical manufacturer with many small trading partners. The company is developing a Web-services-based solution that automates some transactions between the organisations. Sleeper said the approach is a low-cost way to achieve some of the benefits they might have with a larger-scale system from such well-known integration solution vendors as webMethods, TIBCO, or Vitria.
Developing your firm's business and industry expertise
From a more strategic perspective, Sleeper advised that firms -- especially those for which integration work has been a mainstay -- should invest in developing their consultants' knowledge of specific industries and how to apply technology to business processes.
"I think the day of pure technology consulting is on the way out, if it's not already passed," Sleeper said. "When IT organisations look to consultants for help, it's as much for their strategic business expertise as it is for skills with any particular technology."
As the use of Web services technologies eliminates the need for the nuts and bolts aspects of integration services, businesses simply aren't going to be willing to pay as much for them, Sleeper said. So, while technical skills are always important, pragmatic business strategy will become more valuable. However, this doesn't spell an end to integration work, as some have suggested. Sleeper contends that integration will simply become less a part of the consultant's job.
"The folks that claim that this is the death of systems-integration-type consulting are really making an overblown claim," Sleeper said. He believes that integration work will become more focused on how to apply technologies to business process design rather than just getting data from point A to point B.
