  Given the success of the open source phenomenon, it is not surprising that
many organizations are seeking to emulate this success by adopting open source
practices internally in what is termed InnerSource. However, while open source
development and InnerSource are similar in some aspects, they differ
significantly on others, and thus need to be implemented and managed
differently. To the best of our knowledge, there is no significant account of a
successful InnerSource incentivization program. Here we describe a
comprehensive InnerSource incentivization program that was implemented at
Huawei. The program is based on theories of motivation, both intrinsic and
extrinsic, and also includes incentives at the individual, project, and
divisional level, which helps to overcome the barriers that arise when
implementing InnerSource. The program has had very impressive early results,
leading to significant increases in the number of InnerSource projects,
contributors, departments, and lines of code contributed.
