In designing a minimum viable product for Ezypay's secure site, the team applied lean UX principles and focused on: 1) Getting out of the "delivery business" by relying only on internal domain knowledge and prioritizing "just enough" requirements and prototyping. 2) Using personas to help manage scope and prioritization. 3) Shifting to solution-based thinking rather than just rebuilding existing products. 4) Ensuring collaboration and alignment across the team by involving all roles in design workshops and reviews.

2. Hi, my friends call me KC
UX manager at Ezypay/iconnect360
Lead product design & user research
Manage multidisciplinary teams
Microsoft MVP since 2009

3. Some background
before we jump into the juicy bits

4. These were our past products
Design is not something we have been
good at in the past.

5. We have this huge, ongoing project
• That took almost 7 years and is still counting
• To replace our current billing system that cannot
scale to meet our business needs
• It meant replacing our customer service system,
billing engine, secure site, basically everything.
Today, let’s talk about the redesigning the Ezypay Secure
Site

6. It’s basically a portal where our clients can manage their
direct debit customers, do variations and get reports

7. Then…
We rebuilt this
secure site
twice, but we
never seem to
get there
We got on-
board a new
chief architect
from Silicon
Valley
He convinced
the business
to rebuild this
product, again
We knew we
had to do
things
differently to
ship

8. We got this out after 3 months

9. What did we do
differently
and what did we learn

10. Getting out of the delivery business
• We only relied on internal domain knowledge
• “Just enough” requirements & prototyping

11. Personas
• Priceless in scope management and prioritisation

12. SolutionProblem
Solution-based thinking
• We stopped rebuilding what is there, stepped back and
understood the problem and reconsidering the solutions
we have
As an administrator, I want
to increase or reduce the
amount of my customer’s
next direct debit
Edit debit
Add additional payment
Remove additional
payment

13. Collaboration & Alignment
We were all on the same page on our target users, MVP and deadlines
Everyone felt more empowered as they are involved in the design
We got more innovation – E.g.: A new way to handle outstanding payments
Design Workshops - Workshops
with BAs, UI/UX designers,
Developers, QAs and Instructional
designers to kickstart the design of
the customer page, as it is the very
core of the secure site product.
Review Sessions - All roles are
involved in the user story reviews so
everyone is on the same page.

14. UX governance
• MVP doesn’t mean we can ditch UX
• Usability first, Aesthetics second
• Reaching healthy compromises across business priorities,
user needs and technology (Grounded based on your
target users, minimum viable scope and deadlines)

15. Validated learning
• We did user testing on our initial versions.
• Stuff we thought were really important, aren’t
• We uprooted many issues we never expected. E.g.:
Disabled save button
• This guided the prioritisation of our iterative
improvements

16. This is what we covered
