Dimensional modelling
Facts and dimensions structured so every metric has one definition and one source.
Metrics layer
KPIs defined once, in code, and reused by every report and model.
Time-series forecasting
Trend, seasonality and cycle decomposed; ARIMA, exponential smoothing, gradient boosting.
Regression
Linear, logistic and regularised models for drivers, elasticities and expected values.
Classification
Probability that a lead converts, a job runs late, a part fails inspection.
Probabilistic forecasting
Prediction intervals and quantiles, not point estimates alone.
Monte Carlo simulation
Thousands of runs across uncertain inputs to produce a distribution of outcomes.
Scenario analysis
Base, upside and downside cases with the assumptions that separate them.
Anomaly detection
Statistical control limits and model residuals to flag what does not fit.
Optimisation
Linear and constraint programming for schedules, capacity and allocation.
Survival analysis
Time-to-event models for churn, equipment life and job duration.
Cohort analysis
Behaviour tracked by the period a customer, job or campaign started.
Statistical process control
Control charts on cycle time, yield and throughput.
Attribution modelling
Marketing spend and channels weighed against pipeline and revenue.
Data quality scoring
Completeness, consistency and timeliness measured before anything is modelled.
Model monitoring
Forecast accuracy tracked against actuals; models retrained when drift appears.
