Expression of Interest
Navigating Expression of Interest (EOI) Development
Developing a well structured Expression of Interest (EOI) is often the first step in approaching the market for complex or high value procurement activities. Unlike formal Requests for Proposal (RFP) or Requests for Tender (RFT), an EOI is primarily used to understand the capability of the market, identify suitable vendors, and shortlist organisations that are best placed to deliver the activity.
When structured correctly, an EOI allows organisations to explore available expertise, validate delivery approaches, and refine their understanding of the market before committing to a full competitive procurement process. This guide outlines the key elements of an effective EOI, including concept exploration, capability assessment criteria, compliance considerations, and the rules that govern participation in the process.
Capability Assessment – Understanding the Market
While pre qualification requirements determine whether a vendor can participate, capability assessment criteria help determine which vendors are best suited to progress to the next stage of the procurement process.
At the EOI stage, organisations typically focus on understanding how vendors approach similar projects and whether they possess the experience, resources, and technical capability required.
Capability criteria often include:
- Demonstrated experience delivering comparable projects
- Organisational capability and available resources
- Proposed delivery approach or methodology
- Relevant technical expertise
- Project management capability
- Innovation and technology capability
- Identification of potential risks and mitigation strategies
By exploring these areas, organisations gain valuable insights into the strengths and limitations of the market. This information can be used to shortlist vendors and refine the scope before issuing a formal RFx document.
Compliance Declarations – Ensuring Alignment
Compliance declarations form another important layer of assessment in an EOI process. These requirements are not typically as rigid as pre-qualification criteria, but they provide additional assurance that vendors are capable of working within the organisation’s governance framework.
Common compliance declarations may include:
- Willingness to engage using the organisation’s proposed contract structure
- Disclosure of any potential conflicts of interest
- Declaration of any criminal convictions relevant to the services
- Confirmation of relevant insurances
- Disclosure of proposed subcontracting arrangements
- Confirmation of willingness to comply with organisational policies and procedures
These declarations help identify potential risks early and ensure that shortlisted vendors are capable of working within the organisation’s operational and governance requirements.
Ethical and Responsible Procurement
Modern procurement practices increasingly require organisations to demonstrate ethical sourcing and responsible supply chain management.
Including modern slavery and ethical sourcing declarations within an EOI process is an important step toward ensuring vendors align with the organisation’s ethical standards.
EOI processes may require vendors to:
- Confirm compliance with modern slavery legislation
- Declare policies and procedures addressing forced labour and human trafficking
- Provide evidence of responsible supply chain practices
- Confirm that subcontractors also comply with ethical sourcing requirements
These measures help organisations ensure that potential partners align with broader social and governance expectations.
Shortlisting the Market
The primary outcome of an EOI process is typically the creation of a shortlist of capable vendors who will be invited to participate in the next stage of procurement, such as a Request for Proposal (RFP) or Request for Tender (RFT).
To support objective decision making, organisations often use a structured evaluation approach that considers:
- vendor capability and experience
- delivery approach
- organisational capacity
- alignment with project requirements
This structured approach allows organisations to confidently identify vendors who are most capable of delivering the required outcomes.
Rules of Engagement – Maintaining Fairness and Transparency
Clear rules governing participation in the EOI process are essential for maintaining fairness, transparency, and integrity.
These rules establish the expectations for how both the issuing organisation and participating vendors interact throughout the procurement process.
Typical elements of EOI participation terms include:
- Submission guidelines and response requirements
- Confidentiality and non-disclosure obligations
- Procedures for clarifications and addenda
- Ethical conduct requirements
- Dispute resolution processes
- Acknowledgement that participation costs are borne by the vendor
Establishing these terms ensures all participants receive the same information and are treated fairly throughout the process.
From Market Insight to Informed Procurement
A well designed EOI provides organisations with valuable insight into the market before launching a full procurement process. By focusing on capability, experience, and vendor suitability, organisations can confidently shortlist vendors who are most capable of delivering the required outcomes.
This approach ultimately leads to more focused RFx processes, stronger vendor participation, and better procurement outcomes.
