Sydney Water is a New South Wales Government–owned statutory corporation that provides drinking water, wastewater and stormwater services to 5+ million people in Sydney, the Illawarra and the Blue Mountains regions.
Founded in 1882, they are the largest water management organisation in Australia, employing over 2,500 full-time and contract staff.
This project involved the replacement of two existing applications. Both applications included customer and staff portals:
I was the UX lead for the project as part of a very large (20+), multi-disciplinary team. I was very fortunate to work alongside an extremely competent and experienced BA, and our collaboration, together with an adaptive and progressive dev team, was key to the successful outcome of the project.
Both applications were extremely old and obviously suffered from response time and security issues. But other, more user-centric issues were revealed during the HCD research. These issues affected both users and business stakeholders.
The inaccurate information being entered into the Backflow system by external users had to be manually rectified by Sydney Water staff that, together with the handling of the call centre inquiries, were resulting in significant costs for the business unit.
RAS was seeing 70,000 exceptions annually requiring manual fixes involving 3 full-time Sydney Water staff, and equally time consuming work-arounds for the external users.

The HCD (Human Centred Design) activities at the start of the process (pre-COVID), included contextual enquiries (interviews with users in their normal work environment), with end users, SMEs and support staff.
These sessions were videoed and analysed to get a deep understanding of the products and the user journeys, and to identify and highlight user pain points.
The findings from these sessions were synthesised and presented back to the SMEs and the product owner to keep them abreast of the pain points discovered, and to validate our conclusions.
The data was then distilled into several service blueprints illustrating where those pain points occurred in the various user journeys.
5 website surveys and 1 email survey were also launched.
Overall 30 hours of videos were recorded and 50+ pain points were identified.
The pain points were weighted in collaboration with Business, and analysed to ensure business requirements were met, and the most significant the pain points would be addressed.

As a result of the research activities our Business stakeholders were able to validate their requirements, ensuring the future experience would maximise customer satisfaction, and achieve the business goals.
Many features were added into the product backlog (and a few removed), to refine the product development roadmap.
Our research highlighted that one requirement in particular (input validation), that business thought had been already been included, had somehow been left out.
During this stage, Agile methodology was employed in conjunction with Lean UX and n-2 elaboration. This involved BA & UX collaboration in storyboarding and story mapping, two sprints ahead of the sprint delivery team.
HCD outcomes from the discovery phase were workshopped with Business to define the user journeys and create the initial low-fidelity prototypes and refine the final prototypes.
The two applications were extremely complex, involving the integration of multiple platforms (including SAP), and dozens of APIs.
Fortunately, my background in web development (and previous projects), enabled me to understand these complexities, and promote the HCD aspects in a authoritative way to ensure the best possible outcomes.
Budget and time constraints combined with the COVID restrictions to increase the difficulties in completing the project. But the team pulled together incredibly well, despite these, too bring to fruition a successful project.
The final applications are clean, intuitive, mobile-friendly interfaces that meet all of the user and business needs.
Unfortunately, the same budget constraints mean I won't be around to do the post-production user testing, but I have full confidence in the final product achieving it's goals.
"The HCD input on this project resulted in an easy to use, intuitive product that will reduce support calls, and save us money."

Key Business stakeholder/SME - RAS/Backflow
"Arran’s UX and interpersonal communication skills were crucial, and the user interviews provided much needed intel that we have drawn upon again and again throughout the project design.
His HCD approach resulted in an easier journey for the customer/user, reduced the change management impact, and improved user acceptance.
Arran played an instrumental role in securing HCD’s use in future Sydney Water IT projects. It’s a win/win for both the users and the business."
