Engagement models

Structure the work around risk, scope, and certainty.

When the scope is clear, use a fixed milestone. When the unknowns are significant, start with discovery or assessment, then price the next phase from evidence.

01

Fixed Milestone

Defined deliverables, acceptance criteria, timeline and fee for a bounded piece of work.

02

Assessment First

Review an existing system, document findings, then prioritize and quote remediation separately.

03

Ongoing Capacity

Reserved engineering support for evolving priorities, pilots, maintenance and product development.
