The Daily Scrum meeting supports the Scrum value of Openness and the principle of self-organizing teams. This rule of Scrum also aligns with the Agile Manifesto principle “The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.” In-person attendance of all Scrum Team members allows for the fullest level of openness among Team Members. If even one team member attempts to attend this meeting by any other means, either by phone or even video conferencing, efficiency and effectiveness of the openness and self-organization becomes compromised. Compromised self-organization yields compromised collective ownership. The successful delivery of the Sprint Goal requires full commitment on the part of the whole team. Lack of in-person participation increases the likelihood that the team will fail to deliver on its Goal because the openness and self-organization will lack effectiveness.
