critical path 2

Assume you are a new project manager and you have gathered your team to discuss a project that appears to be in trouble. You have invited your supervisor, an experienced project manager, to listen to the conversation and offer advice. After listening for a while, your supervisor says that there is no point in adding more resources to a specific activity under consideration, because it is not going to help. What does the project manager mean and how does it relate to the critical path? Where and when would you add more resources to reduce project duration? Discuss your thoughts on schedule compression techniques and any challenges that you might encounter.
