During a civil engineering project, one of your team members comes to you and asks you if they can use an unconventional way of estimating. As the project manager, you are somewhat familiar with the application area but you are not an expert. You ask the team member to explain the benefits and the risks of this estimating approach. On the surface this, approach seems to result in more accurate information and takes less than one third of the total time of normal estimating methods in your organization. Prior to giving final approval to the team member to use this new way of estimating what should the project manager do? Choose the best answer: - Discuss the benefits and risks of this estimating approach with the project sponsor. - Discuss the benefits and risks of this estimating approach with an experienced engineer. - Discuss the benefits and risks of this estimating approach with the rest of the team. - Discuss the benefits and risks of this estimating approach with the project customer. - Rely on this estimate and move on with the planning
