How we assemble support

Responsibility is agreed, not assumed.

An engagement is built around the question and the capabilities it requires.

DEP defines its leadership or advisory role, identifies specialist needs, and aligns provider contributions with the sponsor’s objectives. The sponsor retains ownership and agreed decision rights.

Names, availability, deliverables, and commercial arrangements are confirmed before individuals or providers are committed to the work.

Before you spend, be sure™.

Start with the decision you need to make.

Tell us what you need help with, the question you have, or the milestone you’re working toward. DEP can help define the next steps and coordinate the work.

You can contact DEP without sharing technical details.
