From the playbook
Practices I teach every team I work with.
Getting Unstuck
A diagnostic framework for teams that know something's wrong but can't name it
Use this when: Your team knows something is off but can't articulate what
Story Writing
Writing stories that developers can actually build from
Use this when: Your stories keep growing mid-sprint or developers keep asking 'what do you actually want?'
AI Maturity
A structured way to assess where your team actually is with AI - and what to work on next
Use this when: Your team is using AI tools but you're not sure if it's working or what to invest in next
Delivery Diagnostics
How to figure out why your team is slow before deciding what to change
Use this when: Velocity is declining, stories keep carrying over, or something feels off but you can't explain why

How Much Does a Fractional Product Manager Cost?
Fractional product managers typically cost $150-350 per hour or $5,000-20,000 per month. But the real question is not what it costs -- it is what it costs you to not have one.
Let's talk about what
you're building
I'm exploring full-time product leadership roles and selectively taking consulting engagements. If you're hiring or need hands-on help, I'd love to hear from you.
