 By extending the concept of _open_ to encompass (for instance) open research, design, or access, we can identify additional benefits that these practices bring to organizations. This broader view of openness is gaining traction in academic and public sectors, where terms other than open source are sometimes used instead, such as [open technology](https://www.researchgate.net/publication/254920512_Open_Technology#pf7) or open work. However, since these terms are not as well-known among organizations, many of them still use open source as a term to indicate activities beyond software.

 ## Step three: Initiate conversations and define unique motivators
 
 Have 1:1 conversations with managers, high-level executives, and workers/contractors from different teams that use open source in their day-to-day operations, or whose strategy involves dealing with open source projects (in terms of licenses, security vulnerabilities). Use the insights from these conversations to define the organization's unique motivators and map them to areas within the organization where open source brings value
