The final result of an A2A workflow is accepted by a named business role, not by the protocol, an agent, or the team that technically handed off the task. Business acceptance of A2A results requires three separate actions: task handoff, result verification, and business approval. A2A governs communication between agents. It does not assign business authority, confirm source reliability, or close unresolved exceptions.
The A2A protocol describes how agents communicate. In this type of collaboration, one agent can send a task to another, receive a status, or take over a result. This is a useful interoperability layer when several systems participate in one workflow.
MCP has a different role: it connects an agent with tools and data. In practice, it is useful to separate the question of how an agent reaches data or tools from the question of how an agent collaborates with other agents. Neither A2A nor MCP answers the third business question on its own: who may state that a result is acceptable for an order, posting, production plan, customer message, or another official action.
A protocol can pass a status such as completed, failed, or needs more information. Such a status describes execution of the communication task. It does not automatically constitute business acceptance.
This distinction matters when a result enters ERP or changes the organisation's obligation. In ORKA's approach, official ERP transactions remain connected to clearly defined business roles, process rules, and verifiable records. Orkasta can support day-to-day work collaboration, while Trueforce can support specialised engineering needs, but ownership of the business decision must remain explicitly assigned by the process owner.
In a well-designed process, the same people do not need to perform all three actions. What matters is recording the transitions and conditions for each transition.
Task handoff starts with the owner of the business request or with a system authorised to make that handoff. The task should include at least:
The technical sender of a message is not necessarily the owner of the request. For example, an integration can send an A2A task on behalf of an ERP process. The business owner still needs to define the task purpose, permitted data, and consequences of an incorrect result.
Result acceptance is the verification that an output meets predefined criteria. A system, a business role, or a combination of automated controls and human review can perform this verification.
Accepting a result is not the same as confirming that an agent returned an answer. A result can be technically complete and still be unacceptable for the business. It may contain data from an unauthorised source, omit a mandatory field, retain unresolved uncertainty, or fall outside assigned authority.
Acceptance criteria should be verifiable. Instead of descriptions such as "the result must be high quality", use rules such as:
The owner of the acceptance criteria should be a named business role. A technical team can build the check, but it should not silently determine acceptable business risk.
Business approval is the decision to take the next official action. It can mean publishing a plan, sending an order, initiating procurement, posting a document, or releasing an outcome to a customer. This decision requires authority derived from the business process, not from the fact that an agent completed its task.
Accountability between AI systems must not blur this point. An agent that drafts a proposal, an agent that checks a document, and an agent that sends a result can have different tasks. None of them gains business authority simply because it is last in the chain.
Before connecting agents through A2A, a team can work through four short questions.
Which result enters a business decision? Separate working notes, recommendations, and drafts from a result that triggers an official action. Only the latter requires defined business acceptance.
Who owns the input? Name the data owner for every key input. Accounting may own the chart of accounts, procurement an approved supplier list, production a work order, or another defined function may own the relevant data. The owner is not necessarily the technical administrator of the source.
Who makes the decision? Name the role authorised to approve, escalate, or reject. Where the decision is fully automated, the process still needs to identify the business owner of the automated rule and a person or role for exceptions.
What happens when the result is not clean? Define the stop condition, routing for review, and recording of the reason. An unresolved exception must not disappear inside a completed status.
This framework often shows that the issue is not interoperability but unclear ownership of data and decisions. Business process screening can help map these transitions before technical implementation.
Consider a hypothetical process in which a first agent extracts data from an incoming document, a second compares the extracted items with approved data in ERP, and a third prepares a proposal for further processing.
The task handoff should define which document is a permitted input, which ERP records serve as reference, and which field must retain a source identifier. The second agent can return a match, mismatch, or missing data. The third agent can prepare the proposal for a business user.
Business acceptance does not belong to the third agent. It belongs to the role authorised to approve further processing of the document under the organisation's rules. If a reference record is missing, an amount does not match, or a source is not recognised, the result goes to a predefined exception workflow. An agent can flag the exception and pass on the required facts. It cannot close a business dispute on its own without a rule and authority.
This example does not prescribe one universal automation threshold. An appropriate level of automation depends on the type of decision, reliability of the source, consequences of error, and existing process controls.
A2A can structure task exchange, but it does not resolve several critical questions.
Full automation can reduce manual work in stable, clearly bounded parts of a process. On the other hand, it can move a hidden rule or incorrect source through several systems faster than a manual process. Controls should therefore be designed before the scope of automation expands.
Before putting the process into operation, record the following:
If a team cannot clearly name the owner of inputs, the decision, and exceptions, it is not ready to transfer business acceptance into an automated workflow. As a next step, map one concrete process from source to official ERP transaction and mark every transition of accountability. For a structured discussion of that scope, talk to the ORKA team .
