Key Takeaways

  • Fixed-Price contracts place maximum risk on the seller, while Cost-Reimbursable contracts place maximum risk on the buyer
  • The three main contract categories are Fixed-Price (FFP, FPIF, FPEPA), Cost-Reimbursable (CPFF, CPIF, CPAF, CPPC), and Time & Materials (T&M)
  • Make-or-buy analysis compares the total cost and benefits of producing in-house versus outsourcing to external vendors
  • Source selection criteria typically include price, quality, technical capability, delivery schedule, financial stability, and past performance
  • In Firm Fixed Price (FFP) contracts, the seller has maximum incentive to control costs because they bear all cost overrun risk

Planning & Managing Procurement

Procurement management involves acquiring goods and services from external sources. Understanding contract types and their risk implications is critical for the PMP exam and effective project management.

Make-or-Buy Analysis

Make-or-buy analysis determines whether to produce goods/services internally or purchase from external sources.

Factors to Consider

Make (In-House)Buy (Outsource)
Core competencyNot a core competency
Capacity availableCapacity not available
Need to maintain controlWilling to delegate control
Trade secrets/IP protectionNo proprietary concerns
Better quality in-houseBetter quality from vendor
Cost-effective internallyCost-effective externally

Cost Comparison Example

FactorMakeBuy
Direct Costs$100,000$80,000
Indirect Costs$30,000$5,000
Opportunity Cost$20,000$0
Total Cost$150,000$85,000

Decision: Buy is more cost-effective in this example.

Beyond Cost

Consider non-financial factors:

  • Quality: Which option delivers higher quality?
  • Risk: What are the risks of each option?
  • Control: How important is control over the work?
  • Capability Development: Is this a skill we should develop?
  • Confidentiality: Are there proprietary concerns?

Contract Types

Contracts are categorized by how risk is allocated between buyer and seller.

Risk Spectrum

BUYER RISK          ←——————————————→          SELLER RISK
     ↓                                              ↓
Cost-Reimbursable    Time & Materials    Fixed-Price
(CPPC → CPFF)           (T&M)           (FPIF → FFP)

Fixed-Price Contracts

In Fixed-Price contracts, the seller agrees to deliver for a set price, assuming most of the cost risk.

Types of Fixed-Price Contracts

TypeDescriptionRisk
Firm Fixed Price (FFP)Set price regardless of seller costsMaximum seller risk
Fixed Price Incentive Fee (FPIF)Base price with incentive for performanceShared risk
Fixed Price with Economic Price Adjustment (FPEPA)Adjusts for economic changes over timeShared risk

Firm Fixed Price (FFP)

  • Most common contract type
  • Seller agrees to a specific price regardless of actual costs
  • Maximum incentive for seller to control costs
  • Best for: Well-defined scope, low uncertainty

Fixed Price Incentive Fee (FPIF)

  • Base price with performance incentives/penalties
  • Includes a price ceiling - costs above ceiling are seller's responsibility
  • Formula: Final Price = Target Price + [(Actual Cost - Target Cost) x Buyer Share Ratio]

Example:

  • Target Cost: $100,000
  • Target Profit: $10,000
  • Target Price: $110,000
  • Price Ceiling: $120,000
  • Share Ratio: 80/20 (Buyer 80%, Seller 20%)

If Actual Cost = $105,000:

  • Cost Overrun = $5,000
  • Buyer Pays Additional: $5,000 x 80% = $4,000
  • Final Price = $110,000 + $4,000 = $114,000

Cost-Reimbursable Contracts

In Cost-Reimbursable contracts, the buyer reimburses the seller's costs plus a fee, assuming most of the cost risk.

Types of Cost-Reimbursable Contracts

TypeFee CalculationSeller Incentive
Cost Plus Fixed Fee (CPFF)Fixed dollar amountModerate to complete on time
Cost Plus Incentive Fee (CPIF)Based on meeting performance targetsStrong to meet targets
Cost Plus Award Fee (CPAF)Based on buyer's subjective evaluationModerate to satisfy buyer
Cost Plus Percentage of Costs (CPPC)Percentage of actual costsNONE - incentive to increase costs

Cost Plus Fixed Fee (CPFF)

  • Buyer reimburses all allowable costs
  • Seller receives fixed fee (not affected by actual costs)
  • Fee calculated as percentage of estimated costs
  • Best for: Undefined scope, high uncertainty

Cost Plus Incentive Fee (CPIF)

  • Buyer reimburses costs plus incentive fee
  • Fee based on achieving specified objectives
  • Cost savings/overruns shared between buyer and seller
  • Best for: When performance targets can be defined

Cost Plus Percentage of Costs (CPPC)

  • Fee is percentage of actual costs
  • Worst for buyer - seller has incentive to increase costs
  • Prohibited for US government contracts

Time and Materials (T&M) Contracts

T&M Contracts combine elements of both fixed-price and cost-reimbursable:

AspectCharacteristics
LaborFixed hourly/daily rates
MaterialsActual cost plus markup
DurationVariable based on actual time
RiskShared between buyer and seller

When to Use T&M

  • Scope cannot be fully defined
  • Need quick start while scope is clarified
  • Short-term or staff augmentation needs
  • Work of unknown duration

T&M Risk Mitigation

To limit buyer risk, add:

  • Not-to-exceed (NTE) clause: Maximum total cost
  • Time limit: Maximum duration
  • Progress milestones: Regular checkpoints

Key Takeaways

  • Make-or-buy analysis compares in-house vs. outsourced options
  • Fixed-Price contracts put risk on seller; Cost-Reimbursable on buyer
  • FFP has maximum seller risk; CPPC has maximum buyer risk
  • T&M shares risk and is best for undefined scope
  • Source selection criteria should be weighted and used objectively
  • CPPC is prohibited for US government contracts
