Optimize Smart Streetlight Control Experience - Part 2


Digitalizing Sunstay Solar luminaires with an existing app ‘Service Tag’ and allow SunStay users to have:
-
Secure device connection (Click on me to view part 1)
-
A seamless experience for lighting configuration and monitoring
Background
Create A Seamless Flow For Smart Streetlight Configuration And Monitoring
I executed the design and coordinated with two product teams to optimize the experiences for light configuration and monitoring and greatly increase the work efficiency of the light installers.
My Responsibilities
-
Led design workstream including research, wireframing, prototyping, testing, etc.
-
In charge of design coordination between 2 product teams
-
Collaborated with both hardware and software teams.
-
Key contributor to business stakeholder coordination to get buy-in

KEY CHALLENGE
Competitiors Already Have Similar Apps

By conducting 4 interviews with the marketers, I had a better understanding on the global markets’ requirements.
I also led the effort to run a SWOT workshop with the marketers. This step further helped me understand the product from a higher scope.
There are a lot of similar products, how can I make our product stand out in the existing markets?
RESEARCH & FINDINGS
Customer Insights From User Interviews
Based on the data from markets, we were able to connect with 5 customers from those regions with mid to large growth rate in Solar streetlights. Through in-depth conversations with the customers, I identified 3 key painpoints as follows:
Key takeaways:

Users Are Not Light Experts
Our customers are actually have very limited knowledge on various light products. They usually have no idea if their dimming curve is proper or not.

Many Repetitive Works
Many installers have to do hundreds of lights per day, and the process is repetitive and also time consuming.
They want to save time on repeated works and work efficiently.

How Do I Know Lights Are Functioning Properly?
Today when our customers encounter problems with lights, the usually have to call for help. It would be more efficient and easy if they could know how to fix without getting help each time.
Learn The Limitations Via Expert Interview

No Real-clock Schedule
Due to limitations on the charge controller, it is NOT possible to let the users set the dimming curves based on real-time...
It sets the challenge for me to design something opposite to users’ common sense of dimming settings.

Connections Can Go Bad
Due to limitation on charge controller, it is NOT possible to let the users set dimming curve based on real-time...
It sets the challenge for me to design something opposite to users’ common sense of dimming settings.
I conducted 3 expert interviews with 2 hardware engineers and 1 industrial designer to fill in the knowledge gaps and learn the limitations This is one of the important steps before the design phase because it ensures my end design is compatible and feasible with the hardware.

Design Goals Summary:
1. Optimize the overall light control experiences and maintain an easy-to-use flow for users
2. Innovate new features that help users increase work efficiency
3. Deliver designs that are compatible with the hardware
FROM INPUTS TO FEATURES
Categorize User Needs Via User Story Map
The users’ pain points are quite scattered throughout the entire journey, so I decided to create a story map in order to categorize the user's needs and mark the key moments of various tasks.


Translate Thinkings Into Workable Use Cases
I created a list of use cases with the following format in order to finalize the list of requests so that different teams will also have a centralized repository for efficient collaborations.
As a "role" I shall be able to "define the task" so that I can "define the benefit". Add any "conditions" to the task.

DESIGN
Composing Mid-Fi Screens
Since time was quite limited, I focused on addressing the main pain points of users and solving tech limitations in mid-fi design.
Recap On The Tech Limits - No Real-Time Clock On Dimming Curve Setting
Use visuals to Guide users step by step to complete dimming curve

Recap On The Problem - Users Are Not Light Experts
Help Users validate dimming schedules

Recap On The Problem - Lot of Repetitive Works Are Needed
Help them reuse the works that has done before


Recap On The Problem - Connctions Can Go Bad
So let users know their status so that they always know what to expect

Live monitor and Help Users troubleshoot

ITERATION
Iterated Based On Feedbacks
Feeback 1: Users have trouble providing required inputs

Feeback 2: Users like the graphs for dimming curve but would like to see the changes live on the graph


Feeback 3: Users need see more information from the gauge

Outcome
Success measured based on SUS & NPS
