15 minute standup meetings right before lunch are an ideal way for a team working on scattered parts of a big project to stay connected to reality. They shouldn't be structured as interrogations. Rather, each team member (works for non-programmers too) gives a brief summary of recent and near-future work, their longer term trajectory, and anything they need another person to review. Other team members then have the opportunity to point out they are working on similar things and need to make sure integration of the separate parts goes smoothly.
