The Ask
Initial: Our team was tasked with optimizing EV battery swap stations, focusing on user experience and design. We collaborated with engineering and product teams to improve station form factors and swappable battery services. Our work involved user research, persona development, and journey mapping to enhance efficiency and user satisfaction in EV infrastructure.

Pivot: Research revealed broader opportunities beyond EVs. We pivoted to explore versatile, portable energy storage solutions applicable across various industries. This shift expanded our focus from EV-specific improvements to potentially groundbreaking innovations in the wider energy storage market.
The Approach
  • User Research & Contextual Inquiry: Conducted structured interviews with 65+ users across diverse demographics. Performed observational studies in 15 different settings to understand energy usage patterns. Facilitated 5 workshops with internal stakeholders to align on project goals and constraints
  • Prototyping & Use Case Testing: Developed 3 distinct battery prototypes based on initial research insights. Tested prototypes in 10 specific use cases, including marketplaces, event centers, and local businesses. Gathered feedback from 20+ potential users during real-world testing scenarios
  • Data Analysis & Insight Generation: Synthesized qualitative data from interviews and observations. Analyzed prototype testing results to identify key performance indicators. Generated 20+ actionable insights to guide product development
  • Jobs-to-be-Done Framework: Mapped 6 core jobs related to portable energy needs. Prioritized jobs based on frequency and importance to users. Aligned jobs with company's technical capabilities and business objectives
  • Service Design & User Journey Mapping: Created comprehensive service blueprint for the new energy storage solutionDeveloped detailed user journey maps for 3 primary personas. Collaborated with cross-functional teams to integrate new service with existing offerings.
Phase 1
User Research & Contextual Inquiry
We recruited people of various profiles within the backup and off-grid power space, and had one-on-one interviews with each one of them, anywhere between 45 minutes to an hour long.

We gained insights into pain points, price sensitivity, essential devices these people wanted to power, their core user experiences , and the maintenance culture built around having any form of backup power installation.

"When the lights go off [in the central market] almost everyone turns on their generators to be able to transact business. The fumes are unbearable and unsafe to breathe in. You also have to shout for customers to hear you over the noise. Its worse when people are not mindful or careless and trip over a generator and burn themselves! " - Akosua, makola market
Phase 3
Data Analysis & Insight Generation
The research insights reveal a complex landscape of backup power needs, where users struggle with frequent outages, diverse energy requirements, and technical challenges. Users across various commercial settings, from barbershops to kiosks, grapple with accurately estimating their power loads and often resort to trial-and-error methods with inverters.

While battery power is perceived as more stable and quieter than generators, installation complexity and safety concerns remain significant hurdles. Cost is a primary consideration, with some users already investing in alternative power solutions. Interestingly, users often ignore recommendations when testing appliances, highlighting a gap between intended use and actual behavior. The findings also underscore the need for higher inverter capacities and improved wiring quality to address fire hazards. Overall, these insights point to a market ripe for innovation in user-friendly, safe, and cost-effective backup power solutions that can cater to the diverse needs of Accra's commercial sector.

Phase 4
Jobs to be Done
Our Jobs To Be Done is a framework that describes in broad terms the various problems that we envisage customers would want to use our products and services to solve. We’ve chosen this framework because it is product-agnostic, and allows us to draw parallels between our offering and other solutions that may be available to the customer, such as generators.

The Jobs to Be Done framework focuses on understanding the underlying tasks, goals, and motivations driving customer behavior, helping businesses identify misalignments between user aspirations and current solutions to drive innovation and create more effective products or services.
Phase 5
Building a Customer Journey & Service Blueprint
This Proposed Customer Journey outlines how a user would interact with the new product/service at every phase.

For each phase,  the key customer values have been elaborated – describing the needs that are most important to users – and the potential interventions which will serve as the foundations of design requirements across hardware, software and service delivery.
