Based on the shared priorities, we recommend starting with phase one or a pilot and moving into phase two once the results meet the agreed-upon targets.
If the proposal aligns with your expectations, the next step would be a short review session with your core stakeholders to cover any open questions and make small adjustments together.
Please suggest a day and time that works best for a quick walkthrough, or share comments directly in your reply if that is easier for your team.
