Open Frameworks and Market Health: When Periodic Supplier Entry Can Add Value

Purpose: How providers can use open framework design, reopening and performance data to maintain competition in markets that change over time.

How providers can use open framework design, reopening and performance data to maintain competition in markets that change over time. This matters because public procurement decisions are rarely isolated events. A choice made during planning can affect competition, affordability, service quality, supplier behaviour and the ability to manage the contract later. The strongest approach is therefore to use the source guidance as part of an end-to-end commercial process, with clear ownership and evidence rather than as a document that is completed after the key decisions have already been taken.

Quick summary

• The Practice Guide describes open frameworks as successive frameworks on substantially the same terms that allow new supplier entry at defined points.
• It identifies fast-evolving markets such as technology, digital services and research as examples where periodic entry may be useful.
• The Guide warns that poorly designed frameworks can lock suppliers out and weaken competition.
• Framework providers are expected to undertake market assessment when designing a framework.
• Supplier numbers, lot structure and pricing mechanisms can influence concentration.

What the guidance means in practice

The source material gives several anchors for that process. The Practice Guide describes open frameworks as successive frameworks on substantially the same terms that allow new supplier entry at defined points. It identifies fast-evolving markets such as technology, digital services and research as examples where periodic entry may be useful. The Guide warns that poorly designed frameworks can lock suppliers out and weaken competition. These are not interchangeable statements: some describe statutory or policy requirements and others describe recommended commercial practice. Teams should identify which category each requirement falls into, apply it to the organisation and procurement in scope, and keep a record of the judgement. Where guidance from 2021 or 2023 predates the Procurement Act 2023, its commercial principles can remain useful, but current legislation, regulations and current statutory guidance take precedence on legal process.

The practical value becomes clearer when the remaining guidance is read alongside the project lifecycle. Framework providers are expected to undertake market assessment when designing a framework. Supplier numbers, lot structure and pricing mechanisms can influence concentration. Providers can use participation and award data to assess whether the framework is attracting a diverse and active supplier base. In day-to-day terms, this means the buyer should be able to answer three questions at any approval point: what outcome are we trying to achieve, what evidence supports the proposed commercial approach, and what will need to be managed after the decision is made? If those answers are weak, more analysis is normally more useful than adding another layer of narrative to an approval paper.

A practical process to follow

A proportionate process can be built into existing governance. The steps below are deliberately practical. They are not a substitute for the detailed source guidance, legal advice or local standing orders, but they provide a useful structure for a procurement or commercial team.

1. Step 1. Assess market entry, innovation pace and supplier turnover before choosing an open structure. Record any assumption that could change the conclusion and when it will be reviewed.
2. Step 2. Set a reopening schedule that reflects realistic market change. Keep the analysis proportionate to the value, risk, novelty and criticality of the requirement.
3. Step 3. Design lots and supplier limits with concentration risk in mind. Capture the source evidence and name the person accountable for the next decision.
4. Step 4. Monitor which appointed suppliers actually bid for and win call-offs. Record any assumption that could change the conclusion and when it will be reviewed.
5. Step 5. Track smaller and third-sector participation where relevant to framework objectives. Keep the analysis proportionate to the value, risk, novelty and criticality of the requirement.
6. Step 6. Use evidence from each period to improve the next successive framework. Capture the source evidence and name the person accountable for the next decision.

What good looks like

Good practice is visible in the decision trail, not only in the final document. A reviewer should be able to follow the line from the service need, through market and cost evidence, to the route, evaluation, contract terms and management arrangements. Where several functions contribute, the file should show who owns each decision and where challenge occurred. The same principle applies to handover: useful assumptions, models, KPI definitions, risks, supplier information and approval conditions should move into mobilisation and contract management instead of being left in the sourcing archive. This continuity is particularly important for long-running public services, where staff can change but the organisation remains accountable for the outcome.

Recommendations for procurement teams

The following recommendations are suitable for teams that want to embed the topic into normal ways of working rather than create a parallel compliance process:

• Do not assume reopening alone creates competition.
• Measure call-off activity as well as framework membership.
• Understand why some appointed suppliers stop bidding.
• Publish clear reopening information so suppliers can plan.
• Use buyer feedback to identify friction in call-off rules.
• Link future design directly to evidence from the current framework.

Common pitfalls to avoid

The most common problems are usually process failures rather than a lack of templates. Watch particularly for the following:

• Using a closed framework in a rapidly changing market without considering supplier lock-out.
• Appointing many suppliers but allowing a small number to win nearly all work.
• Reopening on a timetable unrelated to market development.
• Measuring success only by total spend through the framework.

Easy-to-read takeaway

For open frameworks and market health: when periodic supplier entry can add value, the core discipline is to start early, connect the analysis to a real decision and preserve enough evidence for the next stage of the lifecycle. The source material should help teams make better decisions, not merely produce more paperwork. Before acting on a live procurement, confirm the current version of the Procurement Act 2023, regulations, Procurement Policy Notes and any organisation-specific approvals or delegations. This is especially important for thresholds, notice duties, exemptions and policy requirements that can change over time.
