LOCAL FILES. REAL POSSIBILITIES.

Systems iceberg explorer

Explore events, recurring patterns, structures and mental models with explicit evidence and tests.

Move from a visible event to patterns, structures and mental models. Keep proposed explanations separate from evidence.

Iceberg layers are prompts for inquiry. They do not establish causation or reveal hidden beliefs automatically. Up to 50 rows; 4,000 characters per section, 1,200 per table cell.

Visible event What happened? Describe observable facts.Patterns over time What repeats or changes? Include a time window and data.Structures and incentives Which rules, feedback, delays or resource flows may produce the pattern?Mental models What beliefs or assumptions sustain those structures?Possible leverage point Propose a change and explain the mechanism.Evidence and test plan What would support or disprove this explanation?

How it works

Open systems iceberg explorer, enter your own project details or load the labeled example, then complete the prompts and review the worksheet. Review the results and download your project to continue later.

Supported formats

Editable JSON project up to 1 MB; plain-text report and CSV rows. Up to 50 rows, 4,000 characters per section and 1,200 per cell.

Good to know

Layers organize inquiry; they do not establish causation.

Worked example

Before

Support backlog rises after releases

After

Training delay is a proposed structure to test across releases

A plausible explanation remains a hypothesis until evidence supports it.

Systems iceberg explorer: interpret the result

Explore events, recurring patterns, structures and mental models with explicit evidence and tests. Layers organize inquiry; they do not establish causation. All project files are readable and unencrypted. Save and open them explicitly; there is no automatic browser persistence.

Troubleshooting

Is the deepest iceberg layer always the root cause?

No. Mental models are one perspective. Compare alternative explanations and collect evidence across time rather than treating deeper layers as proven causes.

Common questions

Can I use systems iceberg explorer offline?

Prepare this tool using Offline help while online. After preparation, it runs locally with fresh input. Browser cache eviction remains possible; keep project downloads separately.

Can I use this without an internet connection?

Yes, after you prepare this tool from Offline help and the browser retains its assets. Installation is optional. All processing dependencies are bundled locally.
