Run the learning platform
Show the inputs before making a comparison.
Operational indices compare activity with peers only when the source's minimum-data gates pass.
Admin BI is a separate, admin-only workspace. Staff reporting has its own Overview, Grading and Progress pages.
Three example instructors are fewer than the required five.
Raw inputs can be inspected. A normalized peer index should stay unavailable until the comparison gates pass.

- Submissions / hour

The comparison gates
- Peer instructors
- 3 in the example / at least 5 required
- Scoped instruction hours
- 4 in the example / at least 3 required
- Scoped meaningful submissions
- 47 in the example / at least 10 required
- Comparison context
- Each eligible peer also needs 3 hours and 10 meaningful submissions
Instructional Efficiency Ratio
Meaningful submissions per instruction hour.
Value Realization Index
An operational ratio using completion and resource use, with a fixed 0.8 engagement-stability factor.
Marginal Investment Signal
Required submissions per active learner, divided by scoped instruction hours.
Cost of Friction
A model of friction, with explicit input and comparison context.
Inside the VRI calculation
- Completion
- Required submitted versions / required attempts
- Engagement stability
- Fixed factor: 0.8 in the current calculation
- Resource use
- Scoped instruction hours / active learners
- Raw VRI
- Completion × 0.8 / resource use
The stability factor is a model assumption. It is not measured from this learner sample, and the ratio is not a learning-outcome score.
These are model-defined operational indicators, not audited revenue, measured financial ROI or proof of learning outcomes. The current route uses the V3 business-impact service; older financial-card manifests describe another presentation.
What this part of Arc does
- Program selection with actual input counts
- VRI, IER, MIS and Cost of Friction definitions
- VRI uses a fixed 0.8 engagement-stability factor in the current calculation, not a measured stability outcome
- Peer comparison needs five eligible instructors, each with three instruction hours and ten meaningful submissions; the selected scope also has minimum-data gates
- Raw values, formula detail and opportunity-hour estimates; no measured financial return
This is a browsable portfolio interpretation of Arc’s workflows with fictional examples. Navigation, filtering and theme previews work here; editing, execution and platform services belong to the original application.
Inside the original application.
Real Arc screens and recordings, captured locally with fictional people and work.
Inputs and peers beside the indices
The broader fictional cohort meets the comparison gates. VRI includes a fixed 0.8 stability assumption; these are modeled operational indices.
A narrower scope changes what can be concluded
The seven-day view has insufficient eligible peers and displays absolute values instead of a peer comparison.
Watch this workflow in Arc
The program behind the classroom.
Explore the original admin and scoped school analytics: inventory, nine friction lenses, an open calculation, modeled indices, a comparison gate and the work behind the numbers.
Read the walkthrough
- Inventory and activity
The original BI view separates all-time inventory from activity within the selected period. Every figure comes from fictional local fixtures.
- Nine friction lenses
Nine distinct lenses show different participation and workflow patterns. Labels and calculation controls remain visible in the original interface.
- Open the calculation
The native No-Show explanation opens. A close-up retains its formula, variables and concrete substitution: one qualifying run out of 25 gives 4%.
- Read modeled indices carefully
The 30-day modeled-index view includes five eligible peers. Its VRI calculation includes a fixed 0.8 assumption; these indices are not validated causal measurements of teaching quality.
- Respect the comparison gate
A separately loaded seven-day slice has no eligible peers. Arc retains absolute values and explicitly withholds a fair peer comparison; this differs from the 30-day view shown before it.
- Review queues and grade context
The scoped school analytics view displays review age, score distribution and a class-by-lesson grade matrix. A detail insert makes the matrix values readable.
- Follow lesson progression
Started, submitted and reviewed counts stay separate along the lesson sequence, followed by a weekly trend view. This is fictional history, not reported live program impact.
