The Situation: You are the project manager for constructing a custom house. Your company wants you to complete the construction one month earlier so that your company can recognize the revenue in this fiscal year. You know your current project schedule is based on many previous projects and minimizes costs and negative risks. You have crashed activities and fast tracked multiple activities in the past to shorten the schedule. The Assignment: Using generic ideas of crashing and fast tracking, identify and explain some potential additional costs and risks (both opportunities and threats) that could occur because you are reducing the schedule by one month. The response should consist at least three credible references in addition to the PMBOKGuide with at least one of these being a peer-reviewed journal article. Properly cite your response.
