Blueprints

Figure out what you're going to build before you build it, in small chunks.

The tool for this step

The Sketchbook

Draw it before you build it. Figure out what you're going to build before you build it: the whole thing, cut into small chunks that can each change on their own.

What it is

Blueprints figures out what you are going to build before you build it. Before you build a house, you draw it: the whole thing, its floor plan, its rooms, how they connect, what it stands on, and the order it goes up in.

Here the rooms are chunks: small parts a person in the journey can touch, small enough to build in days, each able to change or be dropped without breaking the others. Fluidity is the number of things allowed to move on their own.

How to run it

Step 1Start from what passedThe journey, its validation from the Simulator, and who said go. What it proved is known; everything else is a question.
Step 2Draw the wholeWhat you are building, in a line or two, and the shape of it, like a floor plan.
Step 3Cut it into chunksEach tied to a moment in the journey, each with the one question it must answer, and connected to the others as loosely as possible.
Step 4Build on what you haveYour people, data, customers and tools come first. Then only what is truly new, in the order you'll build it.

Examples

A

The monthly letter, drawn

The journey cut into chunks: the writing, the paper and printing, the collectible sticker, and the subscription. Each can change without the others. The sticker has to prove it brings people back the next month, or it goes.

Where it goes wrong

  • A feature list with a new nameIf the plan reads like a backlog, the journey has been lost. Every chunk traces back to a moment.
  • Chunks too bigIf a chunk takes months, it isn't a chunk. Cut it again.
  • Welded chunksChunks that can only ship together will only ever fail together.
  • Demolishing to rebuildRebuilding what you already have costs quarters. Rearranging it costs weeks.

What it hands on

The Canvas designs each chunk, and the Foundry builds them, in the order written here.
