The strategy robustness tool provides an evaluation of different strategies against various context scenarios or what is also known as the wind tunneling of strategies. This technique provides a basis for a decision depending on possible future developments (specifically those that organizations are exposed to but cannot control). This is one of the core tools in EIDOS and is to be used after the strategy development and the scenario development in the Option Development tool.

There are classically two questions that can be visualized, discussed and answered with this tool:

1. Which is the overall most robust strategy (meaning “independent of which scenario is becoming reality”)?
2. Which is the most robust strategy in a specific scenario?

With the Option Evaluation (OE) tool, EIDOS supports wind-tunneling and decision-making processes lined to the robustness of possible decisions in different context scenarios. These scenarios provide the criteria against which the strategies can be evaluated. If needed, the evaluation can also be accomplished by looking at another dimension, e.g. 1-3 different calendar years.
