At what stages of a project should the Identify Stakeholders process be performed?

While stakeholder identification should happen at the start of each phase, this answer omits the initial identification triggered by the project charter and misses the trigger of significant changes.

Performing Identify Stakeholders only at project initiation is insufficient because new stakeholders can emerge throughout the project life cycle, especially at phase boundaries.

Waiting until the project manager is concerned about satisfaction is reactive and too infrequent; PMBOK requires proactive, recurring identification tied to defined project events.

According to the PMBOK Guide, Identify Stakeholders is not a one-time activity - it should first be performed when the project charter is produced (initiating), then repeated at the beginning of each project phase as new stakeholders may emerge, and also whenever significant changes occur that could introduce new stakeholders or alter existing stakeholder interests. This iterative approach ensures the stakeholder register accurately reflects who can influence or be affected by the project at all times.
