After preparing the stage 3 plan, the project manager left the company.

After preparing the stage 3 plan, the project manager left the company. The project board has decided that, as the stage plan has been agreed, it will not appoint a project manager for stage 3. The team managers will report directly to the project board and will prepare highlight reports instead of checkpoint reports.

Is this an appropriate tailoring of the roles in the 'managing a stage boundary' process?
