A project manager is leading an engineering project. The project manager must obtain some certifications before mass production, which is scheduled in 3 months. The certification process will require at least 6 months. What should the project manager do next? Engage a consultant to shorten the certification process to meet the schedule requirement. Discuss extending the mass production timeline by 3 months with the project sponsor. Assess and evaluate the certification process and understand the best and worst case scenarios. Meet with senior management to discuss the possibility of an extension to the project timeline
