dewood.orgSee every delay. Measure every step. Fix what matters.
In most recurring processes the work is fast — it’s the waiting between steps that drives your cycle time. PFV makes that waiting visible, measurable, and fixable. Pick your depth below.
Both are short, both are playable, and both run on samples that are already built. Read them or play them.
Climb — one percent of it was work
A detection-engineering team has a year to reach risk-based alerting and produces one analytic a week. Load the same eleven-step process at maturity levels 2, 3, 4 and 5, diagnose what holds each one back, and watch 78 days of lead time become 11 — without anyone working faster. This is the method doing what it was built for.

The honesty test · five missionsDwell — fifty-four days blind, nine days slow
Before you optimise a process, make sure the delay is even in it. A board asks where two months of intruder dwell time went. You split your own number into the part you can time and the part nobody was watching — and find out that most of it was never a queue at all. Read this one first if you suspect flow analysis is a hammer looking for nails.

Same method at four levels of rigour. Every one of them runs in your browser.
The Day Line — how much can you actually carry?
The same arithmetic pointed at your own day. Set the goals you intend to finish, tick what lands, and after three days it tells you your real throughput — and therefore how many it is honest to set tomorrow. Over-setting is arithmetic, not weakness. Nothing leaves your browser.
dewood.org/day → Ground level · Sixty seconds · a napkinPFV on a Napkin — interactive
The whole method on one napkin, with live math. Two counts and one honest hours number tell you how long each item really takes, how little of it is work — and which wait to fix first. Nothing you type leaves the page.
