Understand the method
The final task brings together analytical definitions, layout, interaction and communication. Build one useful dashboard for the operations lead rather than adding every possible metric. Your report should help the reader understand the selected completed-order population, inspect the channel composition and decide what evidence to gather before recommending expansion. Use the same verified data throughout so the result can be reconciled.
Complete the working report
Start from your wireframe or the downloadable learner scaffold. Use a local spreadsheet or dashboard tool; the HTML worked example is one possible implementation, not a required coding exercise. Create the four headline measures, the two diagnostic views, an explanation, an inspectable data table and definitions. If your chosen tool cannot support live filters, make clearly labelled separate views and explain that limitation instead of drawing controls that do nothing.
Preserve the May/All default and a clear way to return to it. Test April, combined months, Web, Store and an empty selection. Show unavailable comparison reasons and denominator behaviour. Keep the current filter visible near the title and in any exported view. If you share a screenshot or printout, it should retain scope, units, counts and the relevant caveat; a detached large number is not a complete report.
Give a short walkthrough
Prepare a two-minute explanation. Begin with the question and population, then describe the May completed-value change. Show why channel composition and the small April store group qualify the aggregate increase. Mention delivery coverage and the absence of costs or causal evidence. Finish with a next investigation. Avoid spending the full presentation reading every card or explaining software menus that do not affect the decision.
A useful demonstration includes one filter change. Select Web and explain how the value comparison changes to −90% against April/Web. Return to the default and show where the definitions and source table can be inspected. This demonstrates that you understand the analytical contract behind the controls. Do not claim the prototype proves a commercial effect simply because the interface works.
Package the evidence
Keep the editable report, unchanged source CSV, metric dictionary, a short decision note and a test record. Include any calculation worksheet or code needed to reproduce your result. Identify the case as fictional and guided practice, especially if adding it to a portfolio. A polished screenshot can introduce the work, but the evidence pack shows how the result was produced and checked.
Use the rubric to improve the work
Review five categories: metric definitions and reconciliation; layout and visual comparison; interaction and edge states; explanation and limitations; reproducibility and usability review. Score each from zero to two. Two means the requirement is complete and correct, one means present but incomplete, and zero means absent or materially wrong. Aim for eight or more with no zero in metric correctness or interaction states. This is a self-review aid, not an accredited assessment.
Open the worked dashboard only after attempting your own version, compare behaviours and explain differences. There can be several good layouts. A different colour balance or chart arrangement is acceptable if the report remains readable and analytically correct. Unsupported metrics, hidden exclusions and inconsistent filter scopes are substantive problems to fix before presentation.
Practical exercise
Build and submit to your own local evidence folder a complete dashboard, the source CSV, metric contract, 100–150 word decision note, state-test record and two-minute walkthrough outline. Include a desktop and narrow-screen view or an explicit limitation of your chosen tool.
Self-review: metric correctness/reconciliation 0–2; layout/charts 0–2; filters/edge states 0–2; explanation/limits 0–2; reproducibility/usability 0–2. Aim for at least eight, with no zero in metrics or interaction. Work remains on your device; there is no course upload or automatic grading.

Worked walkthrough outline
- Question and scope: review the supplied completed-order extract, default May/All, EUR; not a live feed.
- Observation: €3,420 versus €2,900, +17.9%, 20 completed orders each month; AOV €171 versus €145.
- Context: both channel AOVs fall; store share changes 10% → 90%; April store n=2 includes verified A020 at €1,000.
- Interaction: select Web; May value is €180 from two orders, −90% versus April/Web. Reset restores the default.
- Limits and next action: unequal delivery coverage, no costs or causal design; investigate mix, comparable periods and costs before expansion.
The complete worked dashboard is available as dashboard_solution.html. It runs locally using embedded fictional data, supports the stated filters and includes numeric chart labels, an underlying-order table, empty-state handling and definitions. The learner scaffold is deliberately incomplete; it is a layout starting point.
A complete evidence pack can receive two points in each category. A dashboard that uses €135 as May actual AOV fails metric correctness even if its layout is attractive. A Web filter that leaves an All-channel success headline unchanged fails interaction and communication. A source labelled “live” without a live connection fails the handover. Use the rubric to identify concrete revisions rather than treating a visual match to the worked example as proof of correctness.
One more question.
Selected usability references: chart descriptions, meaning beyond colour and keyboard operation. These references do not certify this example.
