Assignment A12 — The Verified Assistant

Skills assessed. Q&A configuration · honest influencer reporting · the decomposition tree · an equipped forecast · generated-DAX review.

Submit: A12_LastFirst.pbix plus a one-page verification memo. Worth 20 points. Where a tenant lacks a feature, the memo's written analysis substitutes — every point is earnable in every lane.

Requirements

  1. Page "Ask": a Q&A visual, with synonyms configured so all three of these resolve correctly: sales → [Total Revenue] · basket size → [Avg Units per Order] · hit rate → [Attainment %]. In the memo: the three test questions you typed and the field-readout each produced.
  2. Influencers, honestly: run key influencers on [Return Rate]. In the memo, write the two-sentence finding — which must reconcile with the verified 2.44–3.82% band (an honest null is the expected result; drama is a red flag in your own work).
  3. Page "Decompose": a decomposition tree on [Total Revenue] with Region, Category, and Subcategory available as splits.
  4. The equipped forecast: monthly revenue line with a 6-month forecast — band visible, and the title or caption stating the assumption ("assumes historical trend and seasonality continue").
  5. Generated-DAX review (memo): the assignment hands you three "assistant-generated" measures below. For each: accept or reject, with the one-sentence reason. Verified figures are your evidence.
    • (a) AOV 2 = DIVIDE ( [Total Revenue], DISTINCTCOUNT ( Sales[OrderID] ) )
    • (b) Cost Estimate = SUMX ( Sales, Sales[Quantity] * Sales[UnitPrice] * 0.42 )
    • (c) Growth = DIVIDE ( [Total Revenue], [Revenue LY] )

Before you submit

  • Type your three Q&A questions one more time and read each field-readout — the memo reports what happened, not what should have.
  • Reread your influencer finding: does it contain the word "drives"? Fix it.
  • Save, close, reopen, verify — for the last weekly time. The capstone inherits the habit.
