Economic Analysis

Profitability Criteria
  • Net Present Value (NPV) Show Me The Money
  • Definition
  • Sum of the Net Cash Flow discounted to time zero
    using a discount rate
  • Benefits
  • Incorporates time value of money easy to
    understand recognizes magnitude of profit
  • Can be used for screening and ranking
  • Disadvantages
  • Independent of the size of the cash flows

8
Profitability Criteria
  • Rate Of Return (ROR)Interest Rate
  • Definition
  • Discount rate which equates the sum of the Net
    Cash Flow after tax to zero
  • Benefits
  • Incorporates time value of money
  • Easy to understand
  • Easy to compare with the cost of capital
  • Disadvantages
  • Independent of the size of the cash flows
  • Can be difficult to determine
  • Assumes reinvestment at same rate

9
Profitability Criteria
  • Payout Time The Money Is Hanging Out There
  • Definition
  • Time for Cumulative Net Cash Flow after tax
    Investment
  • Benefits
  • Simple
  • Indicator of investment risk
  • Disadvantages
  • Ignores time value of money
  • No indication of what happens after payout

10
Profitability Criteria
  • Discounted Profitability Index (DPI)Bang For
    The Buck
  • Definition
  • DPI 1 (NPV of Net Cash Flow / NPV of
    Investment)
  • Benefits
  • Accounts for the relative size of the cash flows
  • Used for screening / ranking
  • Recognizes magnitude of profits
  • Disadvantages
  • Does not give as good an indication of
    sensitivity to additional investment as NPV

11
Cost Estimating
12
What is a Cost Estimate?
  • Realistic representation of final project cost at
    any stage of project development to meet a
    specific project objective
  • Basic Components

13
Quality of Estimate
14
Estimate Methods
  • Phase 1 Estimate--Cost/Capacity curves
  • Phase 2 Estimate--Factored estimate based on
    major equipment costs
  • Phase 3 Estimate--Detail estimate based on bids
    for major equipment and bulk takeoffs

Evolution of Estimate Accuracy
  • PHASE 1
  • IDENTIFY
  • Minimal Engineering
  • Low definition detail
  • Wide accuracy
  • PHASE 2
  • SELECT
  • More Engineering
  • More Definition
  • Moderate accuracy
  • PHASE 3
  • DEVELOP (AFE)
  • Adequate FEL (15-30 Engineering)
  • Well defined
  • /- 10 accuracy

19
Planning / Scheduling
20
Project Time Management - Scheduling
  • Project Time Management includes the processes
    required to ensure timely completion of the
    project
  • Activity Definition - identifying the specific
    activities that must be performed to produce the
    various project deliverables
  • Activity Sequencing - identifying and documenting
    interactivity dependencies
  • Activity Duration Estimating - estimating the
    number of work periods which will be needed
  • Schedule Development - analyzing activity
    sequences, activity duration and resource
    requirements to create the project schedule
  • Schedule Control - controlling changes to the
    project schedule

IDEAS
A Plan Defines Activities Involved in a Project,
Their Logical Sequence, and Their
Inter-Relationship
23
Contingency or Float is Added to Estimates to
Reduce the Risk of Overrun.
Estimates are inaccurate because they are
predictions of future events and the amount of
variation that will actually occur is unknown.

Contracting / Procurement

Current Trends in Contracting Procurement
  • Services
  • Contractor capacity is decreasing
  • Craft workforce shortage
  • Labor rates increasing
  • Materials Equipment
  • Lead times are increasing
  • Prices are increasing
  • Inventories are decreasing
  • Material shortages
  • Marketplace
  • Marketplace is strong
  • Global mega projects
  • Suppliers have choices
  • Fabrication
  • Shop loading is high
  • Pricing is volatile

26
What Can Buyers Do?
  • Demand Planning
  • Plan requirements well in advance
  • Aggregate demand
  • Leverage volume
  • Market Intelligence
  • Use market data to mitigate cost increases
  • Monitor supply/demand
  • Investigate new market entrants
  • Commercial Considerations
  • Have and stick to Strategy
  • Tie cost increases (future decreases) to major
    underlying cost components
  • Leverage volume spend
  • Lengthen term of agreement
  • Define work scope manage contractors
  • Supplier Relationships
  • Exploit long term relationships
  • Qualify additional suppliers
  • Dont let supplier know you are desperate
