What is an Open Procedure? Definition and process at a glance
The Open Procedure is the basic form of public tendering and enables unrestricted participation by all interested bidders.
Core characteristics of the Open Procedure
The Open Procedure is characterized by its unrestricted accessibility. Any company can submit a bid directly after the public notice, without prior qualification review or expression of interest.
- Uniform Solicitation Process for all participants
- Simultaneous review of qualification and bid
- Binding Offer Validity Period for submitted bids
Distinction from other procurement procedures
In contrast to Restricted Solicitation, there is no preselection of bidders. While Negotiated Procurement allows renegotiation, the bids submitted in the Open Procedure are final and binding.
Importance in strategic procurement
The Open Procedure ensures maximum market coverage and competitive intensity. It is particularly suitable for standardized services with clear specifications and supports the objective of achieving optimal value for money through broad market participation.
Procedure: How an Open Procedure works
The systematic execution of the Open Procedure follows a structured process from needs analysis to contract award.
Preparation and tender documents
The basis is a precise Statement of Work with clear technical and commercial requirements. A structured Requirements Document defines all relevant criteria.
- Preparation of the tender documents with Award Criteria
- Definition of the Qualification Criteria for bidders
- Definition of deadlines and modalities
Execution and bid evaluation
After the public notice, the Bid Opening takes place on a specified date. The Bid Evaluation includes both the formal and substantive assessment of all submitted bids.
Contract award and documentation
The Award Decision is based on systematic assessment using an Evaluation Matrix. All procedural steps are documented in the Procurement File and concluded with an Award Memorandum.
Important KPIs and target metrics
The success of Open Procedures is measured using specific key figures that assess the efficiency, quality, and cost-effectiveness of the procurement process.
Process efficiency and cycle times
The procedure duration from the start of the tender to contract award is a key indicator. Typical target values are 60-90 days for standardized services, depending on complexity and Offer Validity Period.
- Average procedure duration in calendar days
- Share of procedures completed on time
- Time required for Bid Evaluation and assessment
Market participation and competitive intensity
The number of bids received per procedure indicates market attractiveness and competitive intensity. Optimal values are between 5-12 qualified bids to ensure sufficient competition with manageable evaluation complexity.
Cost-effectiveness and savings
The cost reduction achieved compared to estimates or previous year's prices measures economic success. In addition, quality metrics such as the degree of fulfillment of the Award Criteria and supplier satisfaction are recorded to enable a holistic assessment.
Risks, dependencies, and countermeasures
The Open Procedure involves specific risks that can be minimized through systematic risk management and preventive measures.
High number of unsuitable bids
Unrestricted participation can lead to a large number of unqualified or incomplete bids. Clear Qualification Criteria and precise Statement of Work significantly reduce this risk.
- Detailed definition of requirements in the tender documents
- Clear wording of minimum qualifications
- Structured Bid Evaluation with standardized checklists
Legal challenge risks
Procedural errors or inadequate documentation can lead to a Bid Protest and review proceedings. A complete Procurement File and compliance with all procedural rules are essential.
Capacity overload during evaluation
A high number of incoming bids can overload evaluation capacities and lead to delays. Efficient Solicitation Management with sufficient staff resources and digital tools is required to ensure timely decisions.

Practical example
A city administration issues a tender for the procurement of 50 electric vehicles using the Open Procedure. After public notice, 12 bids are received from various manufacturers and dealers. The Bid Evaluation is carried out using an Evaluation Matrix with 60% price and 40% technical criteria. Three bids are excluded due to insufficient Qualification Criteria. The contract is awarded to the bidder with the most economically advantageous bid, which is 15% below the estimated value.
- Savings of 180,000 euros compared to the original cost estimate
- Procedure duration of 75 days from start to contract award
- Complete documentation prevents later legal disputes
Current developments and impacts
Digitalization and new technologies are fundamentally changing how Open Procedures are conducted and creating new opportunities for efficiency and transparency.
Digitalization of procurement processes
Electronic Bidding is becoming the standard and enables fully digital processing from publication to contract award. Automated workflows reduce processing times and minimize sources of error.
- Electronic submission and management of bids
- Automated deadline monitoring and notifications
- Digital documentation and archiving
AI-supported bid evaluation
Artificial intelligence is increasingly supporting the objective evaluation of bids through automated analysis and scoring. Machine learning algorithms can detect patterns in bid data and continuously improve the quality of the Evaluation Criteria.
Sustainability and ESG integration
Environmental, social, and governance criteria are becoming more important as Award Criteria. Open Procedures are increasingly integrating sustainability aspects into the specification of services and evaluation matrix in order to embed social responsibility in public procurement.
Conclusion
The Open Procedure is the most transparent and competition-intensive procurement procedure, ensuring maximum market participation and fair equal opportunity. Through systematic preparation, clear Award Criteria, and professional Solicitation Management, optimal results can be achieved. Increasing digitalization and AI support will further improve efficiency and establish the Open Procedure as the gold standard of public procurement.
FAQ
When should the Open Procedure be used?
The Open Procedure is generally possible for public contracts above the EU thresholds and is frequently used for standardized services. It is particularly suitable when maximum competition is desired and no special prequalification of bidders is required.
How does the Open Procedure differ from the Restricted Procedure?
In the Open Procedure, all interested companies can submit a bid directly, whereas in Restricted Solicitation, an initial preselection is carried out through the Prequalification Process. The Open Procedure is single-stage, while the Restricted Procedure is structured in two stages.
What deadlines apply in the Open Procedure?
The minimum deadline for bid submission in EU-wide tenders is 35 days from dispatch of the notice. Shorter deadlines may apply for national procurements. The Offer Validity Period for bids is at least 30 days after the bid submission deadline has expired.
Can bids still be changed after submission?
As a rule, submitted bids are binding and can no longer be changed. A correction is only possible in the case of obvious calculation or clerical errors. Renegotiation is not permitted in the Open Procedure, in contrast to Negotiated Procurement.
