Providing detailed cost estimates for projects with a high degree of uncertainty or where the scope isn't fully defined may not offer value due to frequent changes (to the estimates). (PMBOK Guide, Chapter 7) Assume you are leading a project where this is the case. What would your position be on whether to provide detailed cost estimates? Include whether this would be beneficial or detrimental to the project? Consider the implications to the project manager and the project plan? Provide examples to help explain. Explain thoroughly and please provide references
