Note 1 to entry: A transaction is the atomic unit that leads to a synchronized state in the information systems of
collaborating agents. It is the basic building block to définé the choreography between agents. When an agent
recognizes an event that changes the state of a business object within a business process, it uses a transaction to
synchronize with the collaborating agent. A transaction therefore changes the state of a business process. It carries
the intention of the initiating agent and is represented by a data structure that is définéd by a data model. The
exchange of a transaction may alter legal obligations between business partners.
4 Business environment and high level business requirements
4.1 Introduction
eTendering can be put in place using different procedures, depending on the value and the type of the
contract to be awarded, on the legal nature of the contracting entity and on spécific member state
national legislation. Different tendering procedures that can be used by contracting entities are for
example described by European procurement directives [7] [8] [9] [10].
In open procedures, any economic operator can access the tender documents (including the call for
tenders) and submit a tender before the time expires, without any previous assessment of their
capabilities. In restricted and negotiated procedures and in a competitive dialogue the interested
economic operators have to submit a request to participate in order to be invited in the tendering
process by the contracting entity. When the contracting entity has published a notice, for example using
the standard forms for the publication of notices (eForms) définéd by the Commission Implementing
Regulation (EU) 2019/1780 [11], interested economic operators may subscribe (unscubsribe) to obtain
(not obtain) tendering information using sub process subscribe to procedure. Restricted and negotiated
procedures require sending the invitation to tender to the idéntifiéd candidates.
Once the interested economic operator has subscribed to an open procedure, the contracting entity
provides the procurement documents. This can be repeated at any time until the tender submission
deadline to receive the latest version of the procurement documents has been reached. Additionally,
contracting entities need to push updates to the economic operators that subscribed to a procedure.
Within the call for tenders, contracting entities inform economic operators how to qualify for the
procedure. This may be done by an European Single Procurement Document (ESPD) définéd by the
Commission Implementing Regulation (EU) 2016/7 [12]. Additionally, call for tenders may include pre-
award catalogue information to describe products and services in a common format allowing economic
operators to send offers in a structured way and contracting entities to evaluate products and services
automatically through their tendering tools.
Restricted and negotiated procedures require a previous qualification before submitting a tender. In
restricted and negotiated procedures the contracting entity will send an invitation to tender to the
idéntifiéd candidates which have been selected to submit a tender. In contrast, those economic operators
whose qualifications are being rejected are informed.
Once the economic operator has received the call for tenders or invitation to tender, it can use the sub
process of raising questions about procurement documents. This sub process supports economic
operators asking questions about call for tenders. Answers of the contracting entity are to be sent to all
economic operators that subscribed to the procedure and additionally the call for tenders are updated
and pushed to the subscribers of the procedure.
In case the economic operator decides to submit a tender, he can use the tender submission sub process.
After the submission of a tender, the contracting entity notifiés the economic operator of having received
the tender. Economic operators can also decide to withdraw a tender that was previously submitted.
The contracting entity notifiés the economic operator of having received the tender withdrawal. After
the tender withdrawal, an economic operator may submit a new offer at any time before the tender
submission deadline.
On the opening date, the contracting entity gathers and opens all received tenders. The opening board
members can now evaluate the received tenders. If questions about spécific offers arise during the
course of the evaluation, they can be answered using the tender clarification sub process. This sub
process supports the contracting entity to clarify questions on a tender which has been submitted.
At the end of the evaluation process, the contracting entity needs to inform the participating economic
operators upon the results of the tender evaluation. For this purpose, contracting entities can use the
awarding sub process which provides electronic messaging support to inform the bidders that a contract
has been awarded to a particular economic operator. The contracting entity can use the sub process to
inform the winner(s) at the same time as they inform the unsuccessful tenderers and they has to
individually declare the reasons why they failed. The standstill period also begins with the notification
of the imitated award decision. After the stand still period, the contracting entity can finalizé the contract
with the winning supplier and also send a contract award notice.
4.2 Business goals
The business goals supported by implementing this choreography are spécifiéd in Table 1 .
Table 1 — Business goals
ID Description
G-17014-1:2025-1 No previous bi-lateral setup or agreements required - Parties (economic
operators and contracting entities) should communicate without a previous bi-
lateral setup or agreements.
G-17014-1:2025-2 Transparency - The contracting entity wants to obtain the best value-for-money
by maximising the transparency of its tender procedures in order for economic
operators to easily find this business opportunity.
G-17014-1:2025-3 Equal treatment - The contracting entity has the obligation to treat all economic
operators equally during the whole tender procedure.
G-17014-1:2025-4 Competition - The contracting entity wants to obtain the best value-for-money
by maximising the competition among bidders.
G-17014-1:2025-5 Insurance bid - The economic operator wants insurance that his bid is valid and
has been received by the contracting entity within the time limit set out in the
tender documents.
G-17014-1:2025-6 Interoperability - The Member State policymakers want interoperability
between all tendering solutions in order to facilitate one single European Market
because the better interoperability the more bids.
ID Description
G-17014-1:2025-7 Equal access - economic operators want equal access to all public procurement
business opportunities.
G-17014-1:2025-8 Authentication - The contracting entity wants insurance that it is dealing with
real economic operators during the tender procedure.
G-17014-1:2025-9 Legal valid bid - The contracting entity wants insurance that the bid is signed by
persons mandated by the economic operators therefore being a legally valid bid.
The main business bénéfits to be gained by implementing this choreography are spécifiéd in Table 2.
Table 2 — Business benefits
ID Description
G-1714-1:2025-10 Reduce human errors and resources - Automated matching of the Tender with
the Call for Tender document should eliminate human keying errors and
facilitates redeployment of resources.
G-1714-1:2025-11 Facilitate Automated Tender Preparation - e-Tendering/e-Submission solutions
should allow Economic Operators (semi)automatically to generate a tender
based on the information définéd in procurement documents
G-1714-1:2025-12 Efficiéncy - The contracting entity wants to increase éfficiéncy in the business
process, e.g. when evaluating the received bids, in order to save time and costs.
G-1714-1:2025-13 Integrity of the bid - The contracting entity and the economic operator want
insurance that the integrity of the bid is secured, i.e. insurance of accuracy and
consistency when storing and retrieving data.
G-1714-1:2025-14 Administrative burdens - The Member state policymakers want to lower the
administrative burden in public procurement for economic operators and
contracting entities.
G-1714-1:2025-15 Re-use of information - The economic operator re-uses as much information and
documents as possible when preparing a bid in order to save time and costs.
G-1714-1:2025-16 Standards - The economic operator wants to receive as much as possible
standardized tender documents, in order to easily understand the content and
to easily respond by creating a tender and to respond with standardized evidence
and product information that are requested.
G-1714-1:2025-17 Accountability - The contracting entity - being accountable for the procedure -
doesn't want to make mistakes during the whole tender procedure.
5 Business environment
5.1 General
The intended scope for this choreography is focused on public procurement.
This choreography is intended to support use of electronic documents for processing in
(semi-)automated processes. The legal requirements that were taken into account are requirements
from European legislation, particularly the EU Directives, as mentioned in the Bibliography of this
document.
The list of the transactions that are part of this choreography is définéd in Clause 8.
5.2 Business context
This choreography belongs to the procurement business area that is spécifiéd in Figure 1.
Figure 1 — Pre award context
5.3 Positioning in EIRA
EIRA (European Interoperability Reference Architecture) provides a reference model that enables
architects to position the IOP (InterOPerability) spécifications. This document provides a domain-
spécific IOP spécification to which any SBB (Solution Building Block) implementing the ABB
(Architecture Building Block) should be compliant to. The positioning of this document in the EIRA
context is spécifiéd in Table 3.
IoP spécifications provide a valuable source of information to formulate requirements during
architecture development and solution development. By identifying architectural building blocks
through a common terminology, it
—  helps reuse of cross domain building blocks such for instance e-Signature Vérification and Validation
Service, and e-Timestamp Creation Service;
—    helps synchronization with European solutions such as CEF eDelivery;
—  and will provide guidance in using them to provide the prescribed capability enabling, thus managing
and rationalizing IT portfolios.
