SOA slow: Cliff Mills, NCC Research (September 2009)

An organisation’s application portfolio consists of many varied systems that have been built up over several years, ranging
from bespoke solutions to standalone packages and integrated ERP systems. Add in a merger or acquisition along the way
and you soon have an assortment of applications and systems that may have little in common.
In the longer term, service oriented architecture (SOA) holds out the promise of providing a more adaptable and flexible
architecture, but this is still some way off. So enterprise application integration solutions will be in demand for a considerable
time yet and suppliers need to continually refine their offerings to address the growing integration requirements of
organisations.
In previous surveys, when we’ve asked respondents about
their biggest challenges in software development, the number
one issue by some way has always been ‘linking legacy
systems to new applications’.

An elusive goal: Bob Jarvis, Systems Advisers (November 2009)

Enterprise integration sounds easy, doesn’t it? Just bring a couple of organisations together,
streamline some business processes, re-organise a few workgroups, join up a system or two,
and standardise your hardware and software platforms. Job done…
Were that it were so! The snag is that enterprise integration means many things to many people
and individual views of a requirement don’t necessarily take into account – or are even aware of
– the bigger picture or the downstream effects of change.
The tasks described above are closely interrelated. Typically, you can’t change one without
disrupting the others. For example, a change in organisational structure usually means changes
to business processes; a change in technical platform usually requires changes to application
software; a change in application software often means a modification to a business process,
and so on.
This network of modifications and changes has to happen quickly and in sync to respond to evolving business objectives and
goals, especially in times such as these.
