1. Map the components and their owners
Create one inventory for the trading environment, client systems, execution connections, price sources and hosting. Give each component an owner and record the interface used by its neighbours. Include the systems already selected as well as the decisions still open.
The technical scope follows that map. For example, a CRM account request may involve a client area, a trading platform and a confirmation event. Describe the complete workflow so a successful connection is not mistaken for a completed business operation.
| Layer | Questions to resolve |
|---|---|
| Platform | Which account model, permissions and instruments must be configured? |
| Client operations | Which system owns client and trading-account state? |
| Execution | Which destinations and order workflows must be connected? |
| Data | Where do prices originate and which systems consume them? |
| Infrastructure | Where do services run and who monitors and recovers them? |
2. Specify the interfaces before implementation
Collect the current documentation for each required connection. Define identifiers, supported events and the expected response to an incomplete operation. Where a provider must supply a test environment or specification, make that dependency visible in the launch plan.
Treat price and order paths separately. For client operations, define retry and reconciliation behaviour. For operational access, document the roles and the approved process for changing configuration. These decisions make the acceptance cases more precise.
- Named source systems and stable identifiers.
- Required workflows and supported interface operations.
- Agreed handling of unavailable or incomplete connections.
- An inventory of test environments and provider dependencies.
3. Agree acceptance evidence and handover
Choose examples that demonstrate the workflows the brokerage will actually use. Include representative account operations, instrument availability, price delivery and supported execution outcomes. Record how exceptions are investigated and who is responsible for resolving them.
Before the release, prepare the operating baseline and the support path for each component. Identify what is monitored, who receives an alert and which recovery steps are documented. Agree the release sequence and the checks used to determine that the environment is ready for operation.
- Configuration and interface documentation matched to the delivered scope.
- Recorded results for agreed normal and exception scenarios.
- Monitoring coverage and operational responsibility for each component.
- Release and recovery procedures suited to the selected systems.
