Relevant metrics: Adaptiveness, Time to complete task, Customer feedback
How: Take advantage of Lego bricks' ubiquity and versatility to create quick and simple prototypes of your physical product that are easy to dismantle and tweak.
Why: Lego bricks can help you to quickly assemble a physical prototype that can give users an impression of form and function. Furthermore, Lego bricks allow for quick alterations making them an obvious prototyping tool for co-creation.
This card is part of the Validation Patterns printed card deck
A collection of 60 product experiments that will validate your idea in a matter of days, not months. They are regularly used by product builders at companies like Google, Facebook, Dropbox, and Amazon.Get your deck!
Before the experiment
The first thing to do when planning any kind of test or experiment, is to figure out what you want to test. To make critical assumptions explicit, fill out an experiment sheet as you prepare your test. We created a sample sheet for you to get started. Download the Experiment Sheet.
LEGOs serve as an ubiquitous toolkit
To create rapid prototypes, LEGOs versatility serve to create quick and simple prototypes. They are both quick and easy to build, but also to dismantle and tweak.
To create physical prototypes faster, prototype builders have begun to experiment combining 3D printing (slow to build) with lego pieces, so that 3D printing can be limited to only the part of the physical prototype that is undergoing test.
After the experiment
To make sure you move forward, it is a good idea to systematically record your the insights you learned and what actions or decisions follow. We created a sample Learning Sheet, that will help you capture insights in the process of turning your product ideas successful. Download the Learning Sheet.
3D printing combined with Legos
Waiting 5 hours for a 3D printer to be done can sometimes be too long. This is why prototype professionals are beginning to swap the parts of your 3D print that you don’t need printed, with blocks of LEGO to make rapid prototyping even faster by minimizing the components that needs to come from a 3D printer.
IDEO insulin injection
IDEO used Lego bricks to create multiple prototypes for complex insulin injection devices before even starting to think about real production.
