Welcome to the InnerSource SIG

The FINOS InnerSource Special Interest Group is a community of people implementing, or interested in implementing, InnerSource within their financial services organization in order to increase collaboration and remove/deal with excessive ownership issues that can stall innovation.

It is likely of particular importance to financial services organisations who wish to accelerate their InnerSource practices, share best practices, patterns and anti-patterns and potentially related code in a secure environment in collaboration with others in similar positions. InnerSource can help break down silos, encourage internal collaboration and innovation, accelerate new engineer on-boarding, and identify opportunities to contribute software back to the open source world.

Where appropriate, the InnerSource SIG will also work with InnerSource Commons to share relevant outputs upstream to the broader InnerSource community.

Discussions have an emphasis on challenges and concerns that are particular to Financial Services organizations (e.g. relating to compliance or regulatory constraints).

The InnerSource SIG target audience are individuals responsible for InnerSource implementation within financial services organizations, those in Open Source Program Offices interested in open source culture, behaviour and skills, or tech leaders wishing to increase collaboration and remove / deal with excessive ownership issues that can stall innovation.

Building an Open Source Culture

When people think about open source, most often they think about the engineering aspects: contributing or consuming code. But community and culture are a central part of the open source world and should not be overlooked.
