Whistlebox Design Framework
Agile Design

Invented by Ace Lio


I recently published my thesis in fulfillment of my master's degree specialising in product design (300 pages). A new and improved solution to design and build user interfaces (UI) that could assist in my work reducing expenditure and resources. By utilising 'quantitative' and 'qualitative' research methodology I was able to achieve it.

There are eight popular design frameworks widely used by global enterprises to design and build products centred on their users and business assumptions. UX methodologies generate design frameworks to administer the process of designing user interfaces (UI). Research has shown that organisations that leverage UX are superior to those that compete on functionality or price alone. My research aimed at testing the efficacy of my refined ‘Whistlebox’ design framework, (named after its namesake 'Whistlebox mobile app') by comparing it with the world's two most popular design frameworks: "Lean UX" and Google's "Design Sprint".

The UX Challenge

Having conducted and managed multiple streams of projects, my team risked producing low-quality products for our customers. By using design frameworks we were able to satisfy deadlines but it became an exhaustive practice. To reduce the amount of time and resources building applications I had to find a better solution. By creating a better design framework for the organisation we would be able to achieve our business goals. However, end-users, simulation tools, and professional health practitioners can affect the design process's final design. I identified some issues relating to stakeholder support and timely delivery.

The UX Approach

I will create a UX design framework that will help organisations save time and money in designing and developing UI. By implementing new techniques from cognitive design for UI, organisations can produce high-quality products efficiently.

The Final Product

Based on the literature review on UX design methodologies, three design frameworks were tested and analysed, they were: 'Lean UX', 'Google Design Sprint' and the 'Whistlebox Design Framework'. Participants were seperated into three groups to evaluate the frameworks in order to report their findings. Click here for a full summary of our research


The UX Impact

The best method to achieve a task is the one that uses less effort. The Whistlebox design framework could turn obstacles into opportunities and assist organisations, product owners, and design teams design software rapidly. Analysis of responses demonstrated the ‘Whistlebox’ design framework was by far the most agile framework with unprecedented methodology rapidly accomplishing goals by 50%. The framework was established to improve the development of software. It saved money on resources and reduced our SDLC process significantly by more than 50%. Design frameworks are specifically designed to help organisations organise information with efficacy using visuals to improve UI design. The Whistlebox design framework employs a simple algorithm that applies ‘the principle of least effort’. Its credibility was forged by utilising one UX designer and one software developer (equivalent to one UX unicorn) - this process is usually reserved for a larger team of practitioners. The efficacy of the framework saved our clients from spending tens of thousands of dollars.
