Accelerated prototyping builds powerful user experiences

DK&A set out to redefine and accelerate LähiTapiola’s design and development processes by introducing tangible HTML prototyping into the early stages of the design process.

“The introduction of early prototyping has shortened our time to development, reduced the number of errors, and ensured we don’t have to go back to fix things as often.”

The design process improvements DK&A have enacted hinge on early user testing and subsequent iteration.

“By getting our customers involved in the design process early on, we end up with a quality product that brings them a meaningful user experience,” Maija Lahtikari expands. “We can also test the accessibility of our services at the prototyping stage and make improvements as needed.”

Accessibility is one of the essential concerns for LähiTapiola’s digital services. Fast prototyping and early user testing have helped LähiTapiola keep their end user in mind through all stages of production. This iterative, customer-centered mindset shift has created consistent, powerful, and more accessible user experiences for LähiTapiola’s customers.

Fast prototyping has further helped improve LähiTapiola’s internal communications. “When everyone can see and touch the prototype, there’s less room for different interpretations,” Maija explains. “Everyone lands on the same page more naturally, and it’s easier to make decisions.”

This also makes it easier for LähiTapiola to balance business needs with user experience. When decision-makers can see how business-driven features will impact the final user experience, it is easier to determine the necessary compromises. This has further led to the creation of coherent and powerful user experiences.

A partnership built on the pursuit of excellence

Over the last five years, DK&A and Lähitapiola have worked tirelessly together to improve Lähitapiola’s design and prototyping processes. 

The release of LähiTapiola’s Duet Design System in 2019 has been integral to DK&A’s current, lightning-paced prototyping. DK&A’s developers can quickly build functional prototypes without needing a static backend by reusing existing components in the Duet Design System. We at DK&A have since helped maintain, develop, and add components to the Duet Design System. 

“LähiTapiola’s developers can copy and paste the HTML from our prototypes and then use it in their production application and save time this way,” adds Konrad, Software Engineer at DK&A. Other business units in Lähitapiola can also use the HTML prototypes as a basis for their work. This allows for efficiency gains on a larger scale, with different units being able to work in parallel from an earlier stage.

The prototyping process itself has gone through numerous improvements over time. To validate entirely new user experience flows, the teams have also incorporated Figma prototypes into the design process.

“Figma prototypes let us validate the idea itself before we even create the HTML prototype,” Roope, UX and Product Designer at DK&A, explains. “They let us quickly validate elements like the legal requirements and the general user experience flow. Figma prototypes combine nicely with the later HTML prototypes, covering many design grounds leanly.”

Is there a horizon beyond perfection?

We have reached the three goals set for our long-term partnership between Lähitapiola and DK&A. LähiTapiola’s product development time has been reduced, their internal design processes have been strengthened, and the quality of their digital products has improved.

So then, five years later, has the partnership finally achieved perfection? No, of course not. But we’ve long surpassed excellence in our unwavering, passionate pursuit of the unachievable. We, LähiTapiola and DK&A, continue to push the limits of user-centered design through fast prototyping together.

“The people at DK&A are exceedingly professional and know what they are doing. Our collaboration has been extremely smooth and pleasant.”
