The Friction Model

the system stalls. we measure where.

This is what FACT (Friction Assessment Context Telemetry) measures in real handoffs. The FACT report runs all 9 equations on them. Six supporting models explain the result. One rule keeps it honest.

Direct calculation

nine numbers fromthe real handoffs

The FACT report runs all 9 equations on the real handoffs. Each one's counted from evidence FACT collects. Each line says what it reveals. See a sample FACT report

How FACT works. 2 weeks on site, inside the real handoffs, ending with the FACT report. FACT gets the same access a project manager would. One point person on the team answers questions. Every nondisclosure and confidentiality agreement is signed before day one.

01 · Map score

FACT's measured placement

PROOF gives an early read on which of four patterns the route follows: fragmented, stalled, scaling or compounding. FACT measures it on the real handoffs.

02 · Department score

which team carries the stalled work

Reveals the departments where work waits longest, and the aggregate across the route.

03 · Missing-context rate

how often work arrives incomplete

Reveals the share of handoffs that force someone to stop and go find what was left out.

04 · Repair hours

time spent fixing handoffs

Observed hours come from timed repairs. The estimate scales them by handoff volume and rate per handoff type.

05 · Capacity pressure

how much the week asks for versus what it has

  • < 0.85 margin
  • 0.85 to 1.00 constrained
  • 1.00 to 1.15 overloaded
  • ≥ 1.15 deficit

Reveals whether the team has spare hours, or whether repair work is eating the margin that keeps delivery on time.

06 · Capacity gap

hours the week is short

Reveals the hours that never fit, so work rolls into next week.

07 · Backlog

whether the queue grows

Arrivals and rework add to the queue; completions and cancellations drain it. Reveals the direction the backlog is moving.

08 + 09 · Context repair cost

what the repair time is worth

Prices the hours. Duplicates are subtracted so no hour is counted twice.

Example only: 8 repair hours a week × $43.27 = $346.15 a week. Over 52 weeks that's $18,000 a year, or 20% of one $90,000 salary. The real figure comes from the team's own hours.

Why the work stalls

near full,waiting explodes

A team that looks fully used isn't efficient. As utilization approaches 1, wait time grows without limit. That's queueing math, not a habit problem.

00.51.0 utilization ρ wait

ρ = 0.50

Wait relative to work time: 1.0×

Same team, same skill. Only the load changed.

Supporting models

the theorybehind stalled work

These explain why the measured numbers behave the way they do. They're never used to inflate a cost.

Utilization

how busy the team is

Arrival rate over service rate. Above 0.85, small surprises turn into long queues.

M/M/1 queue

the simplest queue

Shows wait, time in system and queue length all climbing as arrivals near capacity.

Kingman

variability makes it worse

Uneven arrivals and uneven task sizes multiply the wait. Incomplete handoffs add both.

Little's Law

work in progress equals time

More open items at the same rate means each one takes longer to finish.

Bottleneck

the slowest step sets the pace

Speeding up any other step doesn't raise output.

Coordination graph

who hands work to whom

People and teams are nodes, handoffs are edges. More edges means more places for context to go missing.

Honesty

theorem, model,accounting

theorem

Queueing results explain why a full team stalls. They hold in general.

model

Utilization, variability and bottlenecks describe the route. They point to where to look.

accounting

Hours come from observed handoffs. Salary converts them. Nothing else touches the figure.

The theories explain why work stalls. They never multiply the price. Evidence produces the hours and salary converts them.
