Ken Schwaber (who co-developed the Scrum process with Jeff Sutherland in the early 1990s) introduced the concept of chickens and pigs with the daily scrum. Each attendee is either a chicken or a pig. The metaphor comes from the idea of a project to open a restaurant of bacon and eggs. In such a project, the pig is said to be committed but the chicken is merely involved.
The various translations of these cartoon are available on .
Committed and involved could be mapped to the RACI designations for roles and responsibilities. This might help to map an agile process into a more formal or traditional organization :
- Committed (pig) is the equivalent of R(esponsible) and A(ccountable)
- Involved (chicken) is the equivalent of C(onsulted) and I(nformed)
On Agile projects the term Pig has come to describe all the developers, designers and testers who commit to the actual work. The term Chicken is applied to everyone else who make intellectual contributions but do not commit to any work.
