Agile methods and traditional contracts often clash. Fixed-scope contracts, once a staple in software procurement, are poorly suited to the evolving nature of Agile delivery. In contrast, Agile contract models offer flexibility, shared risk, and alignment with continuous value delivery.

Let’s explore the top 5 Agile contract models, where they fit, and how they compare to traditional fixed-price and time & materials (T&M) contracts.

---

1. Time & Materials (T&M) with Variable Scope

What it is:
This model allows the client to pay for the actual hours worked or effort delivered, typically on a weekly or monthly basis. Scope is flexible, evolving through feedback and iterations.

When to Use It:

• Projects with evolving requirements

• High levels of collaboration between customer and vendor

• Early-stage product development where outcomes are uncertain

Benefits:

• Supports iterative discovery

• Enables early feedback loops

• Aligns with Scrum and SAFe development cadences

Drawback:

• Less budget predictability for the client

Use Case Alignment:
This model is ideal for teams trained under SAFe Scrum Master Certification, where regular cadence-based planning and inspection support this structure.

2. Capped Time & Materials (Capped T&M)

What it is:
This is a modified T&M contract with an upper limit on cost. It blends budget control with flexibility in scope.

When to Use It:

• You need flexibility but still want cost predictability

• Projects with a partially defined scope

Benefits:

• Budget risk is limited

• Promotes Agile principles while keeping procurement comfortable

• Encourages responsible vendor delivery

Drawback:

• May result in scope compression toward the cap

Use Case Alignment:
Teams applying Lean budgeting through Leading SAFe Agilist Certification Training are well-equipped to operate under this model.

3. Agile Fixed Price Contract

What it is:
Unlike traditional fixed-price contracts with a frozen scope, this model defines a fixed price for delivering value slices or outcomes rather than a detailed feature list.

When to Use It:

• You’ve already completed a discovery or proof-of-concept phase

• High alignment exists on MVP or major capabilities

• The vendor has Agile experience

Benefits:

• Budget certainty with Agile delivery

• Shared focus on value over scope

• Enables incremental delivery even under a fixed-cost constraint

Drawback:

• Requires trust and maturity from both sides

• Scope negotiation can be complex

Use Case Alignment:
Perfect for Product Owners managing scope under SAFe POPM Certification, where defining MVP and prioritizing by value is key.

4. Target Cost or Shared Risk-Reward Contracts

What it is:
This model sets a target budget and incentivizes both parties to stay within or under it. Savings are shared; overruns are jointly handled, usually at a defined split.

When to Use It:

• Long-term engagements

• Strategic partnerships with shared business outcomes

• Projects involving significant discovery and change

Benefits:

• Drives collaboration and transparency

• Aligns both parties toward efficient delivery

• Encourages outcome-oriented behavior

Drawback:

• More complex to negotiate and track

• Requires a mature governance model

Use Case Alignment:
This suits programs where SAFe Release Train Engineer Certification is applied to lead large value streams with cross-party alignment.

5. Managed-Investment Contract (SAFe-Recommended)

What it is:
Instead of committing to a detailed scope, the client funds a value stream or Agile Release Train (ART) for a period. The vendor is accountable for delivering value iteratively, measured through metrics and milestones.

When to Use It:

• Enterprise-level Agile programs

• Ongoing product development vs. project delivery

• Focus on innovation and speed to market

Benefits:

• Encourages Lean flow of value

• Eliminates waste from scope lock-ins

• Enables fast pivoting based on feedback

Drawback:

• Needs strong trust and governance

• Budget control comes from cadence-based evaluation, not detailed plans

Use Case Alignment:
Advanced teams with SAFe Advanced Scrum Master Certification are equipped to manage the complexity of such governance models.

Agile Fixed Price vs T&M: A Quick Comparison

Aspect	Agile Fixed Price	Time & Materials
Budget Certainty	High	Low
Scope Flexibility	Medium	High
Vendor Risk	High	Low
Customer Involvement	Medium	High

---

Choosing the Right Model

• Startups and MVPs → Capped T&M or Agile T&M

• Enterprise Agile Delivery → Managed-Investment or Target Cost

• Procurement-Driven Organizations → Agile Fixed Price for MVP delivery

• SAFe Program Increments → Blend of Shared-Risk and Timeboxed scope

Final Thoughts

No single contract model fits all Agile initiatives. Instead of forcing Agile into fixed-price structures or relying entirely on open-ended T&M, these five Agile contract models create balance between flexibility, governance, and value delivery.

Procurement teams, Agile Coaches, and RTEs should collaborate early to choose the right model based on delivery maturity, funding approach, and value alignment.

To deepen your understanding of contract design in Agile, refer to the Scaled Agile Framework’s guidance on Agile Contracts which outlines these models with further case examples.
