OSI Board of Directors


The Open Source Initiative (OSI) is managed by a member-elected board of directors that is the ultimate authority responsible for the organization as a California public benefit corporation, with 501(c)3 tax-exempt status.

Current composition

The ten person OSI board is composed of:

  • Four directors elected by OSI Individual Members for two-years terms.
  • Four directors elected by OSI Affiliate Members  for three-years terms.
  • Two directors are appointed for two-years terms by the board itself.

All directors can serve up to a maximum of 6 consecutive years. Before they can run again they must be off the board for 1 year.

The results of elections for both individual and affiliate member board seats are advisory with the OSI Board making the formal appointments to open seats based on the community’s votes.

Responsibilities of OSI Board Directors

The board’s responsibilities include oversight of the organization, supporting the executive director and staff. The board approves the budget, sets strategic direction and defines goals in line with the mission.

OSI Directors are expected to work actively and pro-actively as a member of the board, OSI and open source community. It is understood directors are volunteers, and each will be engaged in professional and personal responsibilities outside OSI. For different reasons, related to work, college/university, family, etc. there will be periods of time where a director will be busy and/or can not commit to the demands of the board or community, either as much as one would like or as much as is needed. However, this should be the exception, not the rule.

Each board member is expected to sign the Board member agreement.
