Challenge-Based Acquisition (CBA) is an innovative federal procurement strategy in which government agencies articulate a specific mission-related problem or need and invite industry to compete by proposing viable solutions, rather than responding to rigid requirements or technical specifications. This approach shifts the focus from prescribing how to achieve results to defining the desired outcomes, allowing vendors to offer novel, flexible, or emerging technologies that meet the challenge in creative ways.
Unlike traditional acquisition methods that detail product characteristics or procedural steps, CBA encourages problem-solving and leverages the private sector’s expertise and agility. It is especially useful when agencies face complex, evolving, or ambiguous requirements that cannot be easily addressed through conventional statements of work.
How Challenge-Based Acquisition Differs From Traditional Procurement
Traditional federal acquisitions typically follow a linear process in which agencies:
- Conduct market research
- Develop a detailed scope of work
- Issue a Request for Proposals (RFP) or similar solicitation
- Evaluate based on predetermined technical and cost criteria
In contrast, CBA starts with a clearly defined problem or desired outcome and leaves it to vendors to determine how best to achieve it. The key distinctions include:
- Problem-first approach: The agency states a need, not a solution.
- Flexibility in execution: Vendors propose methods, technologies, or processes.
- Emphasis on innovation: Unconventional or emerging solutions are welcomed.
- Iterative engagement: Some challenges allow for phases, prototypes, or feedback loops.
This results in a more collaborative, adaptive, and market-driven procurement experience.
Typical Use Cases for Challenge-Based Acquisition
Challenge-Based Acquisition is best suited for environments where:
- Requirements are not fully known at the outset
- Innovation is necessary to meet mission goals
- Rapid technology advancement makes traditional specifications obsolete
- Multiple viable solutions may exist, each with trade-offs
- Agencies seek to tap into non-traditional vendor communities
Common application areas include:
- Cybersecurity and digital resilience
- Artificial intelligence and data science
- Emergency response technologies
- Health innovation and diagnostics
- Advanced energy and sustainability solutions
CBA provides a mechanism for engaging cutting-edge providers, including startups and academic researchers, that may not typically respond to government solicitations.
Structure and Process of a Challenge-Based Acquisition
While CBA is flexible, it generally follows a structured path from challenge definition to contract award. A typical process includes:
- Problem Definition: The agency clearly describes the challenge, outcome, or performance goal it wishes to achieve.
- Industry Engagement: Agencies may host industry days, issue Requests for Information (RFIs), or publish challenge statements to gather interest and ideas.
- Submission of Solutions: Vendors submit proposals that explain how their solution addresses the challenge and achieves the intended outcome.
- Evaluation Criteria: Proposals are assessed based on effectiveness, feasibility, cost, scalability, and other mission-relevant factors.
- Selection and Award: The agency selects the best-fit solution(s) and may award a contract, pilot phase, or further development opportunity.
In some models, the acquisition may include staged competition, with down-selection after initial concept presentations or prototype demonstrations.
Advantages of Challenge-Based Acquisition
Agencies adopting Challenge-Based Acquisition benefit from a number of strategic and operational advantages:
- Encourages innovation: Agencies gain access to new ideas that might not emerge under rigid specifications.
- Faster solution development: The process often moves more quickly than traditional procurement cycles.
- Expanded vendor pool: Smaller firms and non-traditional contractors can participate without needing deep familiarity with federal contracting norms.
- Mission alignment: Solutions are developed specifically to address the agency’s challenge, leading to higher impact.
- Cost-effectiveness: Agencies can compare a range of solutions and cost models before committing to full-scale development or deployment.
These benefits are particularly relevant in high-priority areas where the pace of change outstrips the government’s ability to define exact requirements.
Risks and Considerations
While CBA offers substantial promise, it also comes with potential risks and operational considerations:
- Ambiguity: Poorly defined challenges may yield irrelevant or unfocused responses.
- Evaluation complexity: Comparing different solution types can be difficult without standardised benchmarks.
- Legal compliance: Agencies must ensure that CBA methods align with the Federal Acquisition Regulation (FAR), especially regarding competition and transparency.
- Scalability: Not all successful pilots or prototypes translate easily into long-term, enterprise-scale solutions.
- Contract type selection: Choosing the right contract vehicle for implementation requires expertise.
To mitigate these risks, agencies should engage acquisition, legal, and technical experts early in the process.
Examples of Challenge-Based Acquisition in Practice
Federal agencies have already used CBA in several high-profile cases:
- Department of Health and Human Services (HHS) launched the BARDA DRIVe program, using challenge-based methods to attract novel medical countermeasures and diagnostics.
- Defense Innovation Unit (DIU) applies challenge-based solicitations to acquire non-traditional defense technologies, including advanced materials and autonomous systems.
- Department of Energy (DOE) has used prizes and open challenges to spur innovation in energy storage, building efficiency, and carbon capture.
- NASA’s Centennial Challenges programme invites public participation to solve specific aerospace engineering problems.
These examples demonstrate how CBA enables agencies to reach beyond conventional vendors and procurement practices.
Role of GSA and Acquisition Support
The General Services Administration (GSA) supports Challenge-Based Acquisition through policy guidance, best practices, and available contracting pathways. Agencies can use GSA vehicles, such as:
- Federal Systems Integration and Management Center (FEDSIM) for complex program support
- Assisted Acquisition Services for acquisition planning and execution
- GSA Schedule contracts that include flexible contract types and technical expertise
Additionally, GSA and OMB have issued guidance encouraging flexible acquisition strategies in support of digital transformation and technology modernization goals.
Best Practices for Implementing Challenge-Based Acquisition
To increase the effectiveness of CBA efforts, agencies should consider the following practices:
- Engage stakeholders early, including legal, technical, and mission staff
- Define the challenge clearly and focus on outcomes, not methods
- Conduct open communication with industry through RFIs or informational sessions
- Use flexible evaluation models that reward creativity and value
- Consider using other transaction authorities (OTAs), prize competitions, or phased contracts where appropriate
- Plan for scalability and integration beyond the initial solution phase
These actions help ensure that the agency receives solutions that are both innovative and implementable.
Comparison: CBA vs Other Acquisition Methods
Challenge-Based Acquisition is often contrasted with other alternative procurement strategies:
| Method | Focus | Use Case |
|---|---|---|
| Traditional RFP | Technical specifications | Known requirements, clear path |
| Commercial Solutions Opening (CSO) | Commercial innovations | Rapid prototypes, dual-use tech |
| Broad Agency Announcement (BAA) | Research and development | Scientific exploration, white papers |
| Challenge-Based Acquisition | Problem-solving | Unclear requirements, innovation needs |
Each approach has its place in the federal acquisition ecosystem, and agencies may use them in combination depending on the procurement objective.
Conclusion: Why Challenge-Based Acquisition Matters
Challenge-Based Acquisition represents a strategic evolution in how the federal government buys solutions. By moving from prescriptive specifications to outcome-focused problem statements, agencies can access broader expertise, encourage innovation, and improve the relevance of contractor solutions.
For procurement teams facing complex or fast-changing mission needs, CBA offers a practical, flexible, and legally sound path to better results. As federal missions grow more technologically demanding, CBA is likely to become a more common and valuable tool in the government’s acquisition toolkit.
