Fl use cases: federated analytics life cycle template

Introduction

Briefly describe the project in plain language.

  • Problem and domain:
  • Why federated analytics suits this problem:
  • Who will use the results:

Scope and objectives

Define the project boundaries and goals.

  • Primary objective:
  • Population and setting:
  • Outputs to produce:
    • Predictive model, or
    • Descriptive / inferential statistics, or
    • Privacy preserving dashboards or studies
  • Out of scope:

Assumptions and constraints

Make assumptions explicit to avoid hidden risks.

  • Key assumptions:
  • Constraints (technical, organizational, regulatory):
  • How assumptions will be validated or monitored:

Governance

Policies and roles guiding responsible data and model use. (Note: governance covers oversight and policy; technical controls belong in the Privacy, security, and risk section.)

  • Stakeholders and roles:
  • Approvals and oversight:
  • Legal basis, consent, and agreements:
  • Access and sharing policy for data, models, or results:
  • Publication and dissemination rules:

Data landscape

Describe the data available and site level differences.

  • Clients and data sources:
  • Inclusion and exclusion rules:
  • Feature families and link to data dictionary:
  • Label or outcome definitions (if applicable):
  • Dataset size, class balance, and known biases:
  • Data quality issues:

Standards and harmonization

List conventions that ensure semantic alignment.

  • Vocabularies, ontologies, or coding systems:
  • Unit conventions and mapping rules:
  • Versioning and updates:

Infrastructure

How the federation is run and secured.

  • Federation topology and orchestration:
  • Frameworks and libraries:
  • Client participation policy:
  • Compute, storage, and networking:
  • Monitoring and failure recovery:
  • Simulation or live clients:
  • Security baseline for transport and authentication:

Wrangling

How data are prepared locally.

  • Preprocessing steps and provenance:
  • Train, validation, and test splits (if modeling):
  • Normalization strategy and source of stats:
  • Missing data handling:
  • Class imbalance handling (if modeling):
  • Validation checks and data QA:

Computation plan

Describe methods to be run.

  • If predictive modeling
    • Baselines and algorithms:
    • Personalization or adaptation strategy:
    • Model architectures:
    • Training schedule and early stopping:
    • Hyperparameters and search plan:
  • If analytics without modeling
    • Statistical methods and estimators:
    • Aggregations and query design:
    • Hypothesis tests and assumptions:
    • Privacy budgets (if using differential privacy):
  • Random seeds and reproducibility notes:

Evaluation and success criteria

How results will be judged.

  • If modeling
    • Primary and secondary metrics:
    • Client side evaluation plan:
    • Aggregation across clients:
    • Calibration and threshold selection:
    • Runtime and cost reporting:
    • Statistical tests and uncertainty:
  • If analytics without modeling
    • Estimator accuracy and precision:
    • Coverage or confidence intervals:
    • Agreement with a centralized reference (if feasible):
    • Sensitivity analyses for assumptions:
    • Robustness checks across clients:
    • Runtime and cost reporting:
  • Fairness and subgroup checks when applicable:

Privacy, security, and risk

Technical and procedural safeguards. (Note: this section describes how governance policies are implemented.)

  • Threat model:
  • Controls in use:
    • Secure aggregation
    • Encryption in transit and at rest
    • Differential privacy or k-anonymity if applicable
    • Access logging and audit trail
  • Privacy budget accounting for repeated queries:
  • Incident response and contacts:

Reproducibility and sharing

Make it possible for others to rerun or extend the work.

  • Code repository and commit tag:
  • Environment capture and seeds:
  • Artifacts to release (configs, metrics, models if allowed):
  • Artifact registry or index for traceability:
  • Synthetic samples or data access process:
  • Known limitations and caveats:

Operationalization and maintenance

Plan for use beyond the study.

  • Deployment target and owner:
  • If modeling
    • Monitoring for drift and performance:
    • Update and retraining policy:
  • If analytics without modeling
    • Schedule for recurring queries or dashboards:
    • Change control for query definitions:
  • Site playbooks and operator training:
  • Sunset or rollback plan:

Technology readiness level (TRL)

Describe maturity and supporting evidence.

  • Claimed TRL:
  • Evidence and references:
  • Gaps to reach the next TRL:
  • Target deployment setting:
