Your Work

Productivity in Workspace is accurate, reversible, validated state transformation under time pressure. Some of this is computation (time comparisons, percent change, period columns). Most of it is workspace-state discipline: undo/redo, save versioning, lock semantics, shortcut correctness. Both sides matter for the gate.

Time comparison (DR_0 vs DR_1)

Active: Days 0–30 vs 30–60 · preview slice has 20 of 20 events across the two windows. Gate uses the full ~3,700-event stream.

DR_0

Revenue $108.88 · Orders 2

Duration 30.0 days

DR_1

Revenue $0.0000 · Orders 0

Duration 30.0 days

Δ (DR_0 − DR_1)

Revenue $108.88 · Orders 2

Duration 0.0 days

PC = 100·(Revenue[DR_0] − Revenue[DR_1]) / |Revenue[DR_1]| = ∅

Live from the preview slice. Change DR presets to watch this and Δ shift.

Predict the full-stream values

Percent change (PC)

For days 0–30 vs 30–60, the full-stream answer is approximately −53%.

Time-comparison direction (Δ Orders)

Category with largest Δ (DR_0 − DR_1)

Largest = most positive (or least negative).

If Revenue[DR_1] = 0, what does PC return?

Are the two windows comparable durations? (30.0d vs 30.0d — match)

Workspace state semantics

Does Redo(Undo(s)) recover s when no action follows undo?

After Undo, does a new action clear the Redo stack?

What triggers unsaved-loss risk (R_unsaved)?

Lock semantics

L_pos blocks Move?

L_item blocks EditItem?

Locks change data binding?

Visualization settings mutate…

Map keyboard shortcuts to actions

Ctrl+SCtrl+ZCtrl+YCtrl+CCtrl+V

Quick-breakdown target set: select all browsers that have at least one order in the stream.

What constitutes the click-through failure mode (FastInvalid)?

Evaluation

Practice checks are unlimited and don’t count toward your grade. Final submit is one-time and generates your certificate.

Practice the workspace, ask Dr. Okoye anything, and submit when you're ready. The grade lives in the workspace, not the chat.
