Do the work.
Defend the decision.

The Analyst places you inside Meridian Living Systems, a fictional products-and-services company. Across nine assignments, you step into different analyst roles and confront what clean tutorials remove: unclear requests, competing clocks, unreliable grains, operational limits, and accountable handoffs.

01 / THE SIMULATION WORLD

YOUR EMPLOYER, FOR THE DURATION OF THE WORK

Welcome to Meridian. Your inbox is already full.

The Analyst is the training environment. Meridian Living Systems is the fictional company inside it: a multi-region operator selling connected-home products and subscriptions, dispatching field service, running warehouses and commerce, and supporting customers after the sale.

Meridian has grown through acquisitions, platform migrations, new models, and operational change. Its data reflects that history. Across nine assignments, you move between teams and moments in the same company. The systems, customers, devices, branches, definitions, and consequences belong to one connected estate—not nine unrelated classroom datasets.

02 / OPERATING MODEL

A workbench, not a walkthrough.

Learners receive a role, an imperfect request, a governed data neighborhood, and a deadline. The system supplies tools and evidence—not a hidden preferred conclusion.

Interrogate the estate

Use SQL to establish grain, point-in-time availability, and reconciled evidence before reaching for a model.

Analyze in Python

Profile, visualize, test, backtest, simulate, or model with the package profile appropriate to the assignment.

Leave an audit trail

Export the exact SQL, Python, working notes, final brief, evidence, captured outputs, versions, and hashes in one portable submission.

03 / ASSIGNMENT SEQUENCE

Built to progress.

The sequence moves from metric reconciliation to production-grade model risk. Complexity rises, but judgment begins in assignment one.

FOR INSTRUCTORS AND FACILITATORS

Planning guidance, workload bands, assessment boundaries, and local review tools sit in a deliberately separate instructor desk so the learner route stays focused on the work.
