The team lead on a project has left the organization and management wants to promote engineer A to this position. The project manager is confident that selecting engineer A will add problems to the project and believes that engineer B would better fit this role. The project manager discussed all of the arguments with management but their decision remains unchanged. What should the project manager do? Promote engineer B instead since the project manager has the authority to make this decision. Request management approval that engineer B will be promoted if engineer A fails in this role. Coach engineer B to be prepared to perform this role if and when engineer A fails. Help engineer A to become familiar with this new role and ensure engineer B stays motivated
