Open source: why (1)?

Environment:• Several open source communities with interesting developments• Open source requirement in many research programs• Transparency

Pros:• Positioning – profile raising:

• Dare to share: to strengthen our international position as a independent researchinstitute through collaboration

• Easier to collaborate with universities and research institutes worldwide• Access to research funds with the requirement of open source• Open source will lead to more use of the software, which leads to more specialist advice

and request for developments

• Efficiency:• Faster joint development (time-to-market) with integration of unique expertise of third

parties• Faster mutual development of our knowledge base• Faster response & bug fixing within the community• Larger pool of users and developers for validation of the software

Open source: why (2)?

• It allows researchers and code developers:• to use state of the art open source products for further product developments,• to integrate with own advancements,• to collaborate easily with fellow researchers.

• It enables modelers:• to use the software with no limitation on the number of user licenses,• to run any number of simulations.

Chris Sherwood (USGS) in VIEWS 5:

“Going open source is not just a good business idea, but also a tremendousbenefit to scientists ….. I think Delft3D combines cutting-edge science withrobustness and usability. … I regard Delft3D as one of the best packages in itsfield”.
