Waterfall / running-change reconciliation
A running total built step by step: start, deltas up and down, end — the reconciliation made visible.

Why use it?
Executives read "how did we get from A to B" better in steps than in a table of deltas.
When it helps
Bridging two totals: budgets, headcount, inventory.
How to read it
- Each block starts where the last ended; up is green, down is red by convention.
- The final block must equal the end total — the chart reconciles or it is wrong.
What you need
- Start and end totals
- The ordered deltas
- What each delta is
Things to check
- Do not reorder deltas for drama — the story is in the declared order.
- Do not leave a step unexplained.
Scope of this diagram
Declared deltas; the running total derives from them.
Work with the converted example
- Open the viewer and select
waterfall. Inspect the rendered view and its source. - Open the designer. Keep the selected profile and inspect its legal palette and property controls.
- Change one displayed title or an appropriate data value. Apply the edit and check the resulting diagram.
- Run the verifier and review its diagnostics before moving complete content into review.
- Download your edited DDN source to retain the change.
The example uses the indentation-based ddn-next-1 dialect. The language guide explains reusable definitions, dotted data rows and explicit property blocks.
