Slice it right! The secret to real agility
Why "just build the whole thing" isn't a strategy, and how slicing work by value brings delivery and learning forward.
Read about the dayI help product teams and their leaders get from idea to value to learning, quickly and reliably, through training, coaching and talks.
Hey, I'm David!
ComingMy first book
A practical guide to discovering, delivering and validating value in agile product development. I'm writing it now.
Get notified when it's outScrum, Kanban and SAFe all work for the same underlying reasons. I work at that level, so the change lasts whichever framework you use.
To choose the right things
To help work move smoothly
To adapt when we're not yet sure what's right, and to improve how we work
Not sure which fits? Book a conversation and we'll work it out together.
Training on agility and ways of working, built on its three core pillars: value, flow and learning. Tailored to your teams.

Working alongside your teams and leaders on the work in front of them.
How coaching works
Keynotes and conference talks that are practical, interactive and a bit funny.
See the talksInteractive training on agility and ways of working, focused on its three core pillars: value, flow and learning. Built on real situations and exercises using your own work, so people leave with a shared language and changes they can try the next day.
Length, depth and focus can all be adapted to your teams, your context and the challenges you're facing, with examples drawn from your own work. In person or remote, for one team or across a whole organisation.
Training builds understanding. Coaching makes it stick. I work with your teams and leaders on the work in front of them, and we measure whether it's helping.
Value identification and slicing, board design, feedback loops and flow metrics, applied to the team's real workflow.
When delivery problems sit between teams: visualising dependencies, managing priorities and flow at portfolio level.
Lean change management: clear goals, hypotheses instead of announcements, and simple measures of whether the change is working.
Working sessions with leaders to manage the system of work rather than the people in it.
Talks grounded in real projects, from building a laser for scientists to slicing work in retail tech. Practical, interactive, and usually with a few jokes.

Watch the talkFree tools to use on your own or with your team: exercises from my training, and ways to look at your own sprint and backlog data. The web tools run in your browser: nothing you enter or load is stored or sent anywhere.
Twelve questions on how often you really work with value, learning and flow. See where to focus next.
Slice a real feature into releases and see when value reaches customers. Get a slicing score, then compare with a reference solution.
See which work keeps rolling into the next sprint, and where it gets stuck. Explore the sample, or load a CSV from Azure DevOps or Jira.
Drop weekly ADO or Jira backlog exports to see what climbs, sinks, stalls and skips the queue.
A Chrome extension that gives Azure DevOps tickets a voice. It finds the cards that have sat still too long, highlights them on the board and reads them out at stand-up.
Coming soon. A practical book about understanding, discovering, delivering and validating value in software development. It doesn't add another framework. It explains the principles underneath them, with real examples and plenty of sketches.
"Building things is not enough. Value comes from delivering small bits early, and learning from each one."
Short videos that explain agile and product ideas simply, without skipping the parts that matter.
I started in research, and it stayed with me. I approach organisations the way I approached the lab: understand the system, question assumptions, look for evidence, run experiments and learn from what happens.
For 15 years I've helped teams and organisations improve how they deliver products and services. My focus is value delivery: how organisations identify value, organise work around it, reduce uncertainty, and find out quickly whether what they're doing is making a difference.
A free 30-minute call. Tell me what's getting in the way, and we'll see whether training, coaching or a talk is the right fit.
