SOA applied at an utility company
27
This utility company delivers water to more than 700.00 households in the
Netherlands. Customers can consume different online services on the website, like
water consumption, payment services, etc. This company wants to be able to adapt to
changes in the market and introduce new online services with a short time-to-market.
Reducing the maintenance costs is a secondary goal for this organization.
Situation
Complication
There was a lack of knowledge on service oriented architecture and not a clear vision
how to implement this. The current IT environment and governance was not able to
support a service oriented architecture.
Solution
Accenture and Avanade helped this company by developing a clear vision for their
business and IT. We provided technical consultant who implemented this vision and
we also maintain the solution. We introduced an integration department which is
responsible for applying principles and patterns related to SOA.
