Companies today are confronted with the challenge of necessary cost reductions while at the same time increasing efficiency. Changes to products often take far too long to reach end customers on the market. A consistent DevOps approach can help. DevOps is a software engineering culture and practice that aims to unite software development (Dev) and software operations (Ops) to continuously improve a software product and create added value. It is not only about bringing Dev and Ops together but all involved people. => DevOps brings people, technologies and processes together to continuously create added value. Performing a DevOps transformation is not witchcraft. It is important to start small, select the right people for the team and then constantly and continuously improve.

What is DevOps?
DevOps is a software engineering culture
and practice that aims at unifying software
development (Dev) and software operation
(Ops) to continuously enhance a software
product and deliver value.
The main goal of DevOps is to strongly
advocate fast feedback and repeatability
at all steps of software construction – from
integration, testing and releasing to
deployment and infrastructure management.

ING
▪ Employees: 54’804
▪ Revenue: € 18’080’000’000.-
▪ Area: Global
▪ Business: retail banking, direct banking,
commercial banking, investment banking,
wholesale banking, private banking, asset
management, and insurance service
▪ Peter Jacobs (CIO ING): “…our approach to
DevOps and continuous delivery in IT. Our
aspiration is to go live with new software releases
on a much more frequent basis—every two weeks
rather than having five to six “big launches” a year
as we did in the past. The integration of product
development and IT operations has enabled us to
develop innovative new product features and
position ourselves as the number-one mobile bank
in the Netherlands…” https://mck.co/2OBJ17O
