Engine output, stopped before attribution. This is the forensic dashboard exactly as the MIP 3.3 windows analysis produced it, published so the calculation can be re-run and checked line by line. It is deliberately not a finished expert report: every slip register still reads assign in its responsible-party column, and the attribution KPI therefore reads 0%. Deciding which party is answerable for a slip is analyst work done against the contract and the contemporaneous record, not something the software concludes. Read the worked example that explains this run.

Summary of Findings

Completion moved 17 working days later than the baseline, from 11 September 2025 to 6 October 2025, across three windows. Of those, 17 are not explained by any attribution rule.

Each window’s movement is attributed as section 5 sets out.

Why the Finish Moved

Without attribution rules for the causes, each window is attributed through the activities driving its finish, as section 5 sets out. Every one is listed below with how it moved the finish.

Basis of Measurement

Basis of measurementHow to read the numbers in this report
Day unit
Working days
Every day count in this deliverable is in working days. No calendar-day figure is displayed. Where a contract clause is quoted verbatim in calendar days, the computed equivalent is given in working days alongside.
Calendar
The activity's own P6 calendar
Deltas are counted on the activity's own P6 calendar via work_day_delta. Where no project calendar is available the documented fallback is Monday to Friday with no holidays, and that fallback is disclosed on the affected figure.
Date fields read
P6 Start and Finish columns only
A positive figure means the date moved later between the earlier and the later schedule, which is the adverse direction in this report
Convention: forensic-slip: positive = the date moved later between the two schedules compared
Variance
How it is computed
A positive value means
Completion shift
completion at the later data date - completion at the earlier data date
completion moved later, slip
Activity slip
activity finish in the later schedule - activity finish in the earlier schedule
the activity finishes later, slip
One uniform subtraction order is used, later schedule minus earlier schedule, so a negative figure means the date moved earlier and is a recovery. This is the reverse of the contractor-loss convention used in the contract-versus-baseline deliverables; the two must not be read against each other without converting the sign.

Concurrent Delay Matrix

per-window × per-party attribution grid
Each cell = working days attributed to that party in that window (Window Shift (wd)). Column totals equal the cumulative party share across the project, which is a bookkeeping definition internal to this matrix rather than an AACE rule. The grand total equals the project completion shift in working days (conservation check, per the AACE 29R-03 §3.3.E.13 requirement that the summed per-period net impacts equal the difference between the first and last schedule update in the evaluation). The Finish Driver column names the activity and date field the shift was measured on.
Unattributed dump: 100.0% of the project shift (working days) lands in the Unattributed column with no named responsible party. This matrix does NOT establish party responsibility for that share. It is not a finding that no party is responsible, only that the input slips carried no responsible_party. Assign responsible parties to the driving CP slips before relying on this attribution. Affected window(s): Baseline → Update 1, Update 1 → Update 2, Update 2 → Update 3.

~CASCADE = window had no CP duration growth; attribution inferred from dominant CP slip party. !UNATTRIBUTED = the dominant share of the window shift dropped to Unattributed (no named responsible party). Reference: AACE RP 29R-03 §3.3.I (apportionment) · §4.2 (concurrency).

Slip Velocity & Acceleration

per-window slip-rate trend
Velocity = signed completion shift (working days) ÷ window duration (working days on the same calendar). Acceleration = change in velocity vs the prior window. Half-period estimate (working days) assumes uniform deterioration within the window.

Caveat (cite in any expert report): Slip velocity is a working-day/working-day rate: numerator = working-day completion shift, denominator = working days between data dates on the same calendar (see basis). Midpoint estimates assume uniform deterioration within the window. Actual slip events may have clustered at any point inside the window. The midpoint is a probabilistic centroid, not an observed event date. Cite this caveat in any expert report that quotes the half-period estimate. Velocity is a per-window average rate, not an instantaneous one; acceleration is a finite difference between successive averages and is sensitive to window-length disparity (sign and direction are reliable, magnitude less so).
Recovery windows (negative shift) detected: 0. Reference: AACE RP 29R-03 §3.3 (Windows Analysis: MIP 3.3 Observational / Dynamic).

Float Burndown Across Windows

per-activity float-erosion register, drawing-sheet exhibit
A-07

Criticality predates the window: 17 of 23 activities opened at TF ≤ 0 at Baseline; none demonstrably crossed during 3 windows, while completion moved 17 working days later

Total float in working days (wd), read from the schedule of record at 4 CPM snapshots, Baseline through Update 3 spanning 3 windows, day math on the project working calendar. Criticality test: TF ≤ 0. Sign convention: negative Δ = float lost across the window. Finish driver COM-DEMOB; completion Baseline → Update 3: 17 wd later. Register bands: TF ≤ 0 · 1-5 wd (near-critical) · 6-20 wd · over 20 wd.

Reading notes

  1. Not plotted above: 23 activities with zero net float movement · 21 held TF ≤ 0 at every observation (17 observed at multiple snapshots, 4 single-observation) · 2 held constant positive float. All 23 appear in the register below.
  2. Baseline band counts in the inset carry the register convention: the 4 single-observation entrants are imputed at their only reading. The movement panel plots observed pairs only.
  3. The horizontal scale is linear to 5 wd; no section break is needed.
  4. Band deltas conserve across the population: 0 + 0 + 0 + 0 = 0 over 23 activities.
  5. 4 snapshots are plotted per row: the grey tick is the first observation, the dot the last, and small intermediate ticks mark each observation between them, so the trajectory is retained.
  6. Method caveat (cite in any expert report): Float burndown is post-processing of analyst-supplied CPM snapshots. Accuracy depends on the quality of the underlying schedule updates. Recovery events (TF increase) may reflect legitimate scope removal, schedule optimization, or activity deletion, and the register does not say which. Slip velocity is a linear average; actual burndown may be non-linear. The per-activity float-timeline presentation is not yet published in AACE/SCL literature; it is disclosed here as a CPP enhancement to the cited observational method.
