ThreadLine
Architecture maps · v2.8 · runs offline

Evidence, not drawings.

Your platforms live in a hundred diagrams. ThreadLine turns them into one interactive map you can filter, walk and check, and every connection says where it came from.

See it work

One solution. Four views.

Claims lodgement at Thornbury Mutual, an invented insurer. The same systems, with the same ids, in the business process, the application flow, the infrastructure and the messaging. Every view is the real ThreadLine engine — click a flow, press Play, open a box.

What this view answers

Who does what, in what order — and where a person re-keys a payment.

Try this

  1. Press Headline in the left panel, under the flows.
  2. Play the walk and watch a claim move lane to lane.
  3. Click the re-key step in the Finance lane.

The weak spot, here

A manual step: over-limit payments are typed again by hand, from the claims system into the payments platform.

The weak spot — over-limit payments re-keyed by hand — shows up differently in every view. That is the point of keeping one set of ids.

Why a map, not a diagram

A diagram shows. A map answers.

The questions people ask in an architecture review, and what it takes to answer each one.

How it works

Start from what you already have.

Three ways in. Each one ends with a map you can open from a folder and hand to someone else.

Get the kit
  1. 01

    Have a diagram? Bring it in.

    Visio, draw.io, ArchiMate or SVG. Check what was read, then download the map.

  2. 02

    Only have documents? Start from a brief.

    Two prompts for your assistant and one check by you. Every connection comes back with its source.

  3. 03

    Starting from nothing? Build one here.

    Pick what you are drawing, name the two axes, drop the boxes in, walk the flow.

Checkable · dated · sourced

A map you can argue with.

A headline that is checked

The one-line headline is tested against the map’s own data. If the map disagrees with it, the map will not build.

It knows when it is out of date

Dates on boxes and flows are judged on the day you read the map. Anything past its date is marked OVERDUE, not left quietly wrong.

Every connection is cited

Each line is confirmed, inferred, disputed or unknown, and carries the document it came from. Open the box to read it.

The argument beside the map

A short narrative sits next to the map. Its links open views, and its claims are checked against the data.

Every copy knows its home

A map remembers where it lives. A stale copy forwarded by email says so when it opens.

Nothing leaves the laptop

One HTML file, opened from a folder. No server, no upload. Export PNG or SVG when you need a picture.

More than flows

The same engine, other shapes.

A map is any two axes and the things that move between them. Six examples, from a delivery roadmap to an audio amplifier:

The X axis is time, committed against stretch. Press “What has to land first”.

The family

One map, many maps, and the record.

One map

ThreadLine

Read the argument. One solution on one map: filter it, walk it, check it.

Many maps

StitchLine

Shared systems join your maps. Follow a thread across all of them, and see which map made each claim.

Maps and the record

WeaveLine

Join maps to your catalogue: owners, retirement, and anything critical with no recovery target.

See them work

The four claims maps, joined.

StitchLine and WeaveLine read the same four Thornbury Mutual maps you switched between at the top of the page. One view of each:

Live · StitchLine · which maps share a system

Open full screen (opens in a new tab)

StitchLine finds the eleven systems the four maps share. Click one to see which maps mention it and what each one says. Where they disagree, it says so.

From above

Every map, stitched to what it describes.

Thornbury Mutual, the invented insurer from the demos, seen from above: 105 systems, five teams’ maps, and the threads that tie them together.

Every thread is a real link in the example data: where two maps share a system they stitch together, and the systems no map shows yet stand out.
