Your board or your management expects a position on AI. You want
neither to overpromise, nor to miss the point.
Initiatives are going in every direction
Each department is testing its own tool. Nobody knows what it really
produces, nor what it costs in total.
You want to decide on numbers
You have a list of ideas and a limited budget. What you lack is
a way to choose other than by intuition.
How we work
The goal is a decision, not a report
We start from your real processes and data, not from a catalogue of tools.
And we also tell you where AI adds nothing: that is often the most
profitable finding of the whole audit.
Quantified use casesValue / effortRoadmapNo follow-on commitment
Your processes, your data, your tools and where your teams actually lose time. Business interviews, not a questionnaire.
02
Identify the levers
The use cases where AI brings something measurable, and those where a well-written script would do better and cost less.
03
Prioritise honestly
Every lever quantified and ranked by value and effort, with the prerequisites (data, security, compliance) stated plainly.
04
Make it decidable
A short roadmap with one concrete first step. Including, sometimes, the conclusion that nothing needs launching just yet.
You end up with something to decide on
Not a list of possibilities, but a ranking you can defend in a board meeting,
with the numbers and the prerequisites behind every line.
★ The flagship asset
A map of your levers, ranked by value and effort
Every lever quantified, placed in a specific process, with its data
and compliance prerequisites. You see at a glance where to start,
what can wait and what is better left alone.
