Maps drawn from memory

The map on the wall stopped matching the floor weeks ago

Your current state value stream map was drawn in a conference room from what people remembered, and the process moved on before the marker was capped. Film each step instead, and let the times come off the video.

Two runs, same map

Building a current state value stream map, two ways

Same four steps, same plant, same week. One never gets past collecting times; the other comes back from the floor complete.

You work the loudest box

When the times are remembered, the step that felt slowest wins the workshop. You spend the quarter improving a box that was never holding the line.

You work the real constraint

Cycle, changeover and uptime come off the footage, and the lead time and inventory between steps come with them. When a step changes, you re-shoot that step instead of booking another workshop.

Sound familiar?

Your map was drawn from memory, and it's already wrong

You are about to run another workshop on top of a map you already know is fiction. The boxes hold what people remembered on the day, and the cycle times were estimates even then. A step got rebalanced since, a buffer moved, and the wall never caught up. So the room argues about which number is closest instead of which step to fix.

The map you have today

Drawn from memory

The boxes say what the people in the room recalled, not what the line ran that week.

Times that were guessed

Cycle and lead times are estimates, so the bottleneck you pick may not be the one holding you back.

Stale before it's posted

The process changed while the map was being drawn, and nobody goes back to redraw it.

The map built from video

Times taken from footage

Once it gets uploaded, it analyzes the video. So it could actually help you do the time study fairly quickly and build a Yamazumi chart for you.

One stitched current state

Filmed steps become boxes joined into a current state map with lead times and inventory between them.

Updated by re-shooting

When one step changes, you re-shoot that step rather than redrawing the whole map.

Before the software

What plants try first, and why it fades

1

The two day mapping workshop

Everyone leaves with a map and real energy. The numbers in the boxes came from the room, so the map is only as good as the memories in it.

2

Stopwatch data collection

Someone walks the line with a clipboard for a week. You end up with a handful of cycles per step, taken on the days that person happened to be standing there.

3

Redrawing the map in Excel

The drawing gets tidier and easier to share around. It still repeats what the last workshop said, because nobody re-measures the steps before redrawing them.

How it works

One video per step. One live map.

You walk the process once with a camera instead of filling a whiteboard from memory. Each filmed step becomes a box with real numbers, and the boxes are stitched into a map you can edit, export and branch.

  1. Film each step on the line
  2. Every step becomes a VSM box
  3. Steps stitched into the current state
  4. Review, edit, branch a future state

Step 1

Film each step on the line

One short video per process step, shot by whoever is closest to it. The same footage also serves as the time study.

Step 2

Every step becomes a VSM box

The process box, it's going to be for that one operation, and the same thing for multiple operations. It breaks it down into these three categories, which is value added, semi value added and non value added.

Step 3

Steps stitched into the current state

The boxes are joined into a current state map with lead times and inventory between steps. Several product families can sit on one map, each with its own routing.

Step 4

Review, edit, branch a future state

There's a template for value stream map and you can make edits to it. Once you've actually built different shapes, you can even group them and build your own templates as well for future use. Let's say you've built the current state and future state and you've mapped that out. It's an ongoing process, and once you hit one bottleneck, you basically go to the next one and see opportunity. It keeps moving.

If nothing changes

The life of a map nobody updates

  1. Day one

    The map goes up

    It is printed, taped to the wall, and the improvement list is built straight off it.

  2. A few weeks in

    A step changes

    A line gets rebalanced or a buffer moves, and nothing on the wall changes with it.

  3. A quarter in

    People stop quoting it

    Anyone who works the area knows the numbers are off, so the map stops being used to argue anything.

  4. Next year

    You draw it again

    Another workshop is booked, from memory again, and the same cycle starts over.

Where next

Replace remembered numbers with recorded ones

Each of these starts from what the floor actually did, not what the room recalled on workshop day. Use them to put real times and real steps behind the boxes on the wall.
