Roll-Up and Reconciliation Calculator

Run the Roll-Up and Reconciliation Calculator MicroSim Fullscreen

About This MicroSim

The learner will calculate a feature's allocated shared cost and unit cost, the reconciliation difference between warehouse and invoices, and a normalized cost per million words for two providers, to the tolerances stated for each item. Apply-level work means carrying out procedures on new numbers. Three different calculations, an allocation, a reconciliation, and a normalization, appear in one sim so that the learner sees them as steps of one cost-integrity routine.

This MicroSim belongs to the chapter Cost Attribution Observability Maturity. It uses JavaScript with the shared quiz kit in sims/shared-libs/. All data in it is illustrative.

How to Use

  1. Read the case and commit an answer before any result is shown.
  2. Press Check (or Commit). The sim shows whether the answer is correct and explains why.
  3. A wrong answer gets one more attempt; after the second miss the answer is shown.
  4. After the last item an exploration panel unlocks. It is practice only and is not scored.

Lesson Plan

Audience

Professionals and graduate students learning to estimate and defend the cost and return of generative AI.

Duration

10-15 minutes

Bloom's Taxonomy

Apply (calculate)

Prerequisites

per-feature cost tracking, vendor invoice reconciliation, cost data normalization

Activities

  1. Predict (5-10 min): work through the committed challenges before any answer is revealed.
  2. Explore (5 min): use the controls unlocked after the last challenge to see how each input changes the result.

Assessment

For each of eight items the learner types a value before the answer is shown. A value is correct when it is within the tolerance in the Content table. Mastery is 7 of 8 correct on the first attempt. Exploration with the adjustable quantities is not evidence.

Common Misconceptions

(1) Shared costs belong to no feature. (2) A higher price per token always means a higher cost for the same work. (3) A small reconciliation difference needs no explanation.
