Reflection and Discussion Forum Week 9Assigned Readings:Chapter. 9 Reducing Project DurationInitial Postings: Read and reflect on the assigned readings for the week. Then post what you thought was the most important concept(s), method(s), term(s), and/or any other thing that you felt was worthy of your understanding in each assigned textbook chapter.Your initial post should be based upon the assigned reading for the week, so the textbook should be a source listed in your reference section and cited within the body of the text. Other sources are not required but feel free to use them if they aid in your discussion.Also, provide a graduate-level response to each of the following questions:
- It is possible to shorten the critical path and save money. Explain how.
[Your post must be substantive and demonstrate insight gained from the course material. Postings must be in the student's own words – do not provide quotes!] [Your initial post should be at least 450+ words and in APA format (including Times New Roman with font size 12 and double spaced). Post the actual body of your paper in the discussion thread then attach a Word version of the paper for APA review]

Rationale for Reducing Project Duration
Time Is Money: Cost-Time Tradeoffs
Reducing the time of a critical activity usually incurs additional direct costs.
Cost-time solutions focus on reducing (crashing) activities on the critical path to shorten overall duration of the project.
Reasons for imposed project duration dates:
Time-to-market pressures
Unforeseen delays
Incentive contracts (bonuses for early completion)
Imposed deadlines and contract commitments
Overhead and public goodwill costs
Pressure to move resources to other projects

Explanation of Project Costs
Project Indirect Costs
Costs that cannot be associated with any particular work package or project activity
Supervision, administration, consultants, and interest
Costs that vary (increase) with time
Reducing project time directly reduces indirect costs
Project Direct Costs
Normal costs that can be assigned directly to a specific work package or project activity
Labor, materials, equipment, and subcontractors
Crashing activities increases direct costs.

Constructing a Project Cost–Duration Graph
Determining Activities to Shorten
Shorten the activities with the smallest increase in cost per unit of time
Assumptions:
The cost-time relationship is linear.
Normal time assumes low-cost, efficient methods to complete the activity.
Crash time represents a limit—the greatest time reduction possible under realistic conditions.
Slope represents a constant cost per unit of time.
All accelerations must occur within the normal and crash times.
