<strong>Planning</strong> <strong>and</strong> <strong>Impleme</strong>nting SOA<br />
www.butlergroup.com<br />
Large organisations tend to have a greater need for integrating applications <strong>and</strong> services across their<br />
businesses. They are also more often challenged with unforeseen <strong>and</strong> changing dynamics created by M&A<br />
activity, new partnerships, expansion, <strong>and</strong> new customer requirements. SOA promises to deliver the ability<br />
to change <strong>and</strong> modify enterprise processes to match such changes<br />
As might be expected,<br />
Technology <strong>and</strong><br />
Financial Services are<br />
the dominant verticals<br />
in terms of SOA<br />
adoption.<br />
dynamically to business processes <strong>and</strong> activity. Smaller organisations may<br />
either be less mature in their usage of technology, or may simply have fewer<br />
business drivers that are forcing a review of alternatives such as SOA.<br />
As might be expected, Technology <strong>and</strong> Financial Services are the dominant<br />
verticals in terms of SOA adoption. They are heavily dependent on IT <strong>and</strong> are<br />
sophisticated in terms of their IT adoption. Enterprises within these verticals<br />
usually run a large number of applications <strong>and</strong> their operations are often<br />
spread across various locations, meaning that the need to integrate processes<br />
across platforms is a constant priority. They also have large, knowledgeable IT-departments <strong>and</strong> are<br />
consequently less inhibited by new technologies. Other verticals, such as Healthcare, Manufacturing, <strong>and</strong><br />
the Public Sector, currently have lower SOA adoption rates, largely due to a more risk-averse approach to<br />
the adoption of the latest technologies, but also likely to be related to other business drivers taking<br />
precedence, <strong>and</strong> a lack of underst<strong>and</strong>ing.<br />

Across different regions, the Datamonitor survey backs up discussions with various infrastructure <strong>and</strong> technology<br />
vendors that implied that there is little difference in adoption rates, at least between the US <strong>and</strong> Europe, Middle<br />
East, <strong>and</strong> Africa (EMEA) regions. Some 48% of positive respondents were based in the US <strong>and</strong> 42% in EMEA.<br />
Vendor discussions imply that adoption rates are marginally higher in the US than in Europe, but most agreed<br />
that adoption was probably lower than might be expected from the volume of hype that surrounds SOA.<br />
The Web site eBizQ (www.ebizq.net)– which covers many integration-related issues – published a survey of<br />
just over 300 of its members in October 2006. This indicated a rather more bullish uptake of SOA, with<br />
28% of respondents claiming to have some services deployed, with another 21% considering themselves<br />
to be in the pilot stages. A further 24% are currently exploring SOA. In most cases, of those organisations<br />
that had deployed some services, there were fewer than ten in production, with Web services being the<br />
most widely adopted service type; here there were a few respondents that had significantly more than ten<br />
deployed services with some 10% having more than 100 in use. Again, Financial Services, Telecoms, <strong>and</strong><br />
Technology companies were at the forefront, backing up the Datamonitor findings (some 21 different<br />
industries were represented in the response group). The main drivers for adoption were increased business<br />
agility, IT reuse, business process optimisation, <strong>and</strong> composite application development (multiple responses<br />
were permitted in the survey). This response did imply that the business was driving much of the adoption.<br />
