#### Challenge

## Deciding whether to join a costly supplier sustainability initiative

Daan faced an important decision: should Westland Kaas join a significant and costly sustainability initiative proposed by a key supplier? Before committing to this project, he wanted to make sure that participating in this project would result in tangible benefits for the planet and the company. He needed a clear path to either confidently support the initiative or justify declining it.

#### Solution

## Validation questions and a business case structure, built with Spirefly

Daan was guided through a strategic workflow. Spirefly highlighted that the decision couldn't be made without more information and proposed generating a list of targeted questions to ask the supplier. These questions were perfectly tailored to validate the program's integrity and value. Taking it a step further, the assistant then suggested structuring all this information into a compelling business case, complete with a 'cost of inaction' scenario.

#### Result

## A validated supplier initiative and a ready business case

The session transformed a single, blocking question into a clear, actionable strategy. Daan walked away with a tailored set of validation questions for his supplier and a ready-to-use structure for an internal business case. Spirefly provided not just the necessary tools, but also the strategic clarity and confidence needed to drive a significant investment decision forward.
