Lessons learned the hard way on our
journey building digital products.

With the person sat behind you,
you have 2 minutes to discuss:

8. How we used to build
products and services

10. How we build services
now

11. User needs first

12. Start with user needs

15. User Research
• User Researchers in the team.
• Every Sprint.
• Team actively encouraged to
go.
• Research using prototyping
and the live service.
• Includes assisted digital users.

16. Benefits
• 5 participants can identify 80%
usability problems.
• Team gain greater
understanding of what works
and what doesn't in the
service.
• Service ultimately end up
clearer and easier to use.
• Happy users!

17. Top tips!
• Be aware of Stakeholders/user
need conflict.
• Watch out for morale in the
team.
• Dont forget you are domain
experts!
• Test the whole service, not just
the website or app.

21. Team make up
• Not just dev and test.
• service manager, product manager, delivery
manager, technical architect, assisted digital lead,
designer, user researcher, developer, content
designer, web operations engineer, performance
analyst, front-end developer
• T-shaping is necessary to avoid massive teams.

22. Top tips!
• Tailor team processes to account for
research and design.
• Avoid team churn, knowledge is not
fungible.
• Not everyone wants to work in these
teams!
• Not all of these roles are best filled
by IT people.
• Open plan offices are terrible team
spaces!
• Avoid sharing key resources
between teams.

23. Benefits

24. Servant Leadership
• Remove barriers from the
team progressing.
• Coach and mentor
• Emotive listener
• Ego-less
• Knows when to solve
problems and when to push
for self resolution.
• Hard!

25. Ceremonies
• Daily stand ups
• Planning and refinement
• Show and Tell
• Retrospective

26. Top tips!
• Report progress in terms that
business stakeholders care
about (value).
• Don’t become Scrum Zombies.
• Inspect and adapt is VITAL!
• Don’t commit to delivery dates
before knowing velocity.
• Be alert to ‘elastic band’ effect.
• Good coaches help (but they
are very rare).

27. Microservices

30. Benefits
• Decoupled, easier to change.
• Decoupled, better fault
tolerance.
• Horizontal scaling.
• API based, easy to re-use over
the internet.
• Technology agnostic, you can
pick th technology best for the
service.

31. Challenges
• Team is first so has to build all the new api’s.
• Team gets all the pain of building new things.
• Team slows down to build features not required by service.
• Team slows down further integrating back to legacy
systems.
• Stakeholders dont see complexity so question progress
• Team slowly loses will to live.

33. Different approach.
• Team build api, but only for the features required by
the service they are developing.
• Follow up team requiring more features develops
those features on the api.
• Risk, who ‘owns’ the api (support).

34. Top tips!
• Try to identify all of the
services you will need up front
(but you will probably miss
some!)
• Identify features needed for
the service versus enterprise
needs.
• Keep an eye on the size of
your micro services.
• Ensure clear ‘contract’s’
between services.

35. Continuous Delivery
(Well nearly)

36. How we used to deploy

37. How we deploy now.

38. Our approach to Devops
• We have a separate webops team for deploys to
prod and pre-prod.
• One place to go.

40. Our approach to Devops
• Team dedicated to hosting automation and platform
management so devs have less to figure out.
• Not perfect but a good balance.

41. Benefits
• Smaller change = less risk
• Easier to deliver fixes quicker.
• Develop and Master code
stays closer together reducing
merge conflicts.
• Responsibility for deploy and
support means teams think
more about supportability.

42. Top tips!
• Make sure your product owner is willing to balance fixes
versus new features.
• Plan for how to handle sprint commitments when deploying
to prod during sprints.
• Log all changes in one place!
• Keep front line support staff updated with changes.
• Keep examining your branching strategy.
• And finally…

45. More top tips!
• Make prod deploy your definition
of done from the outset!
• Put the work in clearing approvals
in your definition of ready.
• Expect resistance!
• Invest the time in good
acceptance criteria (TDD).
• Automate as much as possible.
• Automate some more!
• Prepare for things to go wrong…

yet.

48. In summary
• agile transformation is hard, its a long term investment.
• agile transformation is a means to an end, not the product or
service (this makes funding a challenge).
• Silo’s everywhere!!
• Communication and a thick skin is key!
• Clear objectives and support from the top.
• Don’t lose sight on why you are transforming!
• Talk to your peers in industry!
