Manual

At this basic maturity level –

  • Task execution is often manual, with minimal automation in data processing, model training, deployment, and monitoring. This results in a machine learning lifecycle that is hard to replicate or automate consistently.
  • The machine learning lifecycle is often unstructured, difficult to repeat, and dependent on individual expertise
  • Teams often work in isolation, with fragmented workflows. The process typically relies heavily on the expertise of individual data scientists, occasionally supported by data engineers or software developers for business process integration.
  • Version control for code and model versioning is mostly manual, leading to infrequent and less structured releases. Limited documentation and lack of code versioning can result in unintended code changes and insufficient rollback options, hindering process repeatability.
  • The absence of centralised model performance tracking could make it difficult to scale operations, reproduce results, or efficiently update models. Comparing model iterations could also be challenging due to these limitations.
  • A structured system for monitoring model performance is often missing, leading to potential undetected model degradation that can negatively impact business outcomes.
  • With infrequent model retraining in production, it is difficult to quickly adapt to new trends or integrate the latest model improvements, limiting responsiveness and innovation.

Repeatable

To advance to Repeatable, follow these foundational steps:

1. Introduce basic DevOps principles

  • Version control: Implement version control for code and data to ensure consistency and track changes. Use platforms like Git for source code management.

2. Automate key tasks

  • Data ingestion and preprocessing: Begin automating repetitive data ingestion and preprocessing steps with pipelines (e.g., Apache Airflow or Prefect). This helps make data preparation more efficient and less prone to human error.
  • Model training: Set up scripts or basic pipelines to automate initial model training tasks, making it easier to retrain and reproduce results as needed.

3. Standardise documentation and processes

  • Documentation: Document basic workflows, including data sources, preprocessing steps, model training configurations, and deployment steps. This promotes consistency across teams.
  • Establish repeatable processes: Create templates or guidelines for repeatable processes in model development, training, and deployment, helping reduce ad-hoc practices.

4. Encourage collaboration across teams

  • Cross-functional team alignment: Foster better communication and collaboration between data scientists, data engineers, and operations teams. Define clear roles and responsibilities for each step in the pipeline.
  • Shared knowledge base: Develop a central repository or wiki for team knowledge, including guidelines, troubleshooting tips, and project workflows.

5. Implement basic monitoring for models

  • Basic model monitoring: Begin tracking simple performance metrics for models in production, like accuracy or error rates, and log them for review. While not fully automated, this allows the team to start observing model behaviour post-deployment.
  • Set up manual checks: Establish manual review checkpoints to catch issues in model performance or data quality until automated monitoring systems are put in place.

By following these steps, your organisation can move from a primarily manual, ad-hoc approach to a more repeatable, DevOps-driven setup that lays the foundation for automated and scalable MLOps practices in the future.
