The Orchestration module in LDAS is designed to simplify and automate lab operations by providing pre built and configurable BPMN-based workflows. It enables data flow between instruments and systems like ELNs, LIMS, data lakes, data warehouses, data visualisation systems, etc — reducing manual effort and minimizing errors.
This module supports protocol enforcement, business rule application, and validation checks to ensure data accuracy, standardization, and regulatory compliance across lab processes.

Key Terms

This section provides an overview of the terminologies used in Orchestration.

BPMN

Business Process Model and Notation (BPMN) allows you to visualize your internal procedures using a graphical representation. It also facilitates clear communication of these processes in a standardized format across your organization.

Models

In Camunda BPMN, a workflow model is a graphical representation of a business process using the Business Process Model and Notation (BPMN) standard. This model includes various elements such as tasks, events, gateways, and flows that define the sequence and logic of the process.

You can build these models using the Camunda Model, ensuring they meet BPMN 2.0 standards. After publishing, it can be used to launch workflows.

Task

This refers to a small unit of work defined within a model that must be completed as part of the overall workflow. For example, you can use a receive task to wait for a notification message indicating that a new batch of samples has arrived at the laboratory. Once you receive the message, the workflow proceeds to the next steps.

Events

Events serve as triggers within a workflow that influence process behaviour. For instance, start events initiate a process, Timer events handle time-based actions like sending reminders, and Error events manage exceptions.

Workflow

A workflow represents a sequence of automated tasks designed to execute a specific lab protocol. Using BPMN models, you can define and orchestrate these tasks to streamline operations, reduce manual effort, and ensure consistency.
For example, in a flow cytometry workflow, orchestration module can automate sample registration, standardize data, send it to FlowJo for analysis, and push the results to an ELN—all without manual intervention. Workflows are built using BPMN models, where tasks and events can be executed in parallel based on your lab’s protocol requirements.
