To realize reuse benefits, companies integrate open source assets and are also interested in reusing internally developed assets.  However, reuse is mostly practiced in an ad-hoc way, which implies that companies are not able to fully leverage reuse benefits. Furthermore, often when reuse is practised, it is not well-aligned with the continuous integration (CI), as well as delivery and deployment (CD) practices. The focus is all too often on maximizing the benefits at the individual product level, rather than at the organizational level. The open source community is practising reuse as part of their development. However, when practiced internally, reuse has some additional issues to consider such as, who will sponsor the reusable assets and who maintains them.

The OSIR project aims to fill these gaps by proposing a framework (OSIR framework) for practising reuse of assets. The intention is to optimize the benefits at the organization level and to align it with the CI and CD practices to further improve the flow. Furthermore, the project aims to build on the way-of-working in the open source community to facilitate and speed up the uptake of systematic company internal reuse. In particular, the project will contribute to novel solutions for using “inner source” to support the systematic practice of internal reuse at the organization level. The OSIR framework will also provide support for measuring the value created by practising reuse in a systematic way.
