Is the IT-department the main driver of innovation in your organization?

This depends on the definition of innovation.  For a consumer products or any products company, innovation is defined around the product and service offerings and will most likely be driven from the product development teams and marketing teams.  Internal innovation in business processes and business operations however more often than not is orchestrated by the IT or if one exists central strategy and transformation function.

This is definitely our business - and as we moved to a federated technology organisation we also moved a more technically able workforce out to be more directly connected to further accelerate and enable this. It may also be the nature of our business as we are an R&D focused biotech - so innovation is key to success and a part of our DNA. At the centre now as a more tech run organisation we do operate invest budget focusing on innovation, but this has to be aligned with our strategic objectives and in support of business goals. We are maturing this model so I would not pretend we are there yet, and innovation is always I believe a partnership - but for us science-based innovation leveraging the best we can offer with technology is a good place to start.

Business sectors also have a strong role to play on innovation.  At IT, we typically offer solutions.  They could be innovative on a technological way.   But for a business innovation, it has to come from the line of business.

The IT department is most effective when it enables innovation. Drivers for inniovation should come from across the business.
