Learn, practice, review.

Choose the format that fits

Short lessons explain one idea. Guides organise a practical process. Exercises give you a task to attempt; a worked answer or download is included only when available. Practical cases combine the method, an assignment, an answer and supporting files.

How to use the practical cases

Read the lesson and smaller example, attempt the student workbook, then compare the worked answer and scoring rubric. Instructors can discuss assumptions, alternatives and missing evidence. Completion times are estimates, not measured results.

Data and assumptions

The original set of 18 practical cases uses original synthetic data. They are not client cases, observed market benchmarks or validated hiring assessments. Each case states its assumptions and limitations. Worked solutions explain one approach; well-supported alternatives can also be valid.

Files and permissions

Downloads are available to inspect and practise the exercises. Broader redistribution and institutional licensing terms have not been established. The current practical case downloads are version 1.1; the source CSV is unchanged. Check the file version when comparing answers.
