Spectrum Check & Sweep

Ensuring Full Coverage

The Spectrum Check is a quick diagnostic tool that uses the ELSI framework to verify a project has considered all relevant dimensions of sustainability. Used most in Step 1 and during evaluation.

How It Works

Walk through each ELSI8 category (Energy, Materials, Ecosystems, Species, Culture, Economy, Health, Happiness) and for each ask:

• What is the current state in this category?
• What are the main areas of concern and opportunity?
• What data do we have, and what is missing?

The Spectrum Sweep

A Spectrum Sweep is the more thorough version: a formal analysis producing a structured overview of all ELSI categories with qualitative or quantitative scores. It supports goal setting, indicator development, and solution brainstorming. When done with a diverse team, it quickly reveals which areas receive attention and which are overlooked — often a revealing insight in itself.

When to Use

Use a Spectrum Check at the start of every project to establish baseline awareness. Use a Spectrum Sweep during deeper analytical phases for comprehensive coverage. Return to both during evaluation to verify that proposed solutions do not create new externalizations in previously unexamined domains.
