Three doors, depending on where you are
I take on a small number of engagements at a time. Each of these is scoped so the first useful output arrives early, not at the end.
Start as a bounded decision, not a transformation program
Large-firm programs are appropriate when the mandate is enterprise-wide transformation. These engagements begin with a fixed scope, keep the principal on the work and produce the first decision artifact early—so a buyer can route the work as a departmental review before manufacturing program-scale procurement.
A proposal states the fee; the public site does not. The comparison is about scope, senior attention and approval path—not an unsupported competitor price claim.
If any of this is live for you
The fastest route is a conversation. Bring the architecture you are worried about — the first useful thing usually surfaces inside twenty minutes.
