OUR processes

We offer Consultancy, Courses and Coaching for all of our processes.


Our Processes have been developed from extensive independent research, and course content authored by leading universities in the areas of problem solving, decision skills, sustainability and critical thinking as well as content we designed for undergraduate courses in critical thinking, sustainability and leadership.

We blend these methodologies according to your specific needs providing you with a unique solution for solving complex problems and developing decision skills.

All our processes are audited with the 3E approach, (Empathy, Empowerment and Efficacy)  developed at InterroBang.

The best solutions align all three sweet spots (Innovation, Sustainability and 3E).

Design Thinking

Empathy, collaboration, iteration and rapidly moving to prototyping are the key features of Design Thinking.

3D Thinking


​Often we don't find the right solution because we are asking the wrong questions. Framing the problem accurately makes sure we avoid this common mistake.

Empathy and active listening are essential skills to DISCOVER effective framing.


Responding to the challenge presented by the problem, teams with diverse skills DEVELOP a wide range of creative alternatives using many ideation strategies to find innovative solutions.

Visualisation techniques help to be communicate the ideas with stakeholders in order to get valuable feedback.


These visualisations are further refined to design prototypes which are tested with the end user to provide more feedback.

With a crafted implementation strategy the solution is DELIVERED to the end user. This is a further opportunity for valuable feedback and ongoing improvements.

The Sustainability Sweet Spot

Truly sustainable solutions consider the 'Three Pillars of Sustainability', economic, social and environmental factors.


By considering all three elements, solutions become sustainably aligned and are guaranteed to provide a strong return on investment with significant benefits for users. This is true whether the end user is a client, social group or an individual (you).

Sustainable solutions are long-term solutions because they make financial sense and respect people and our environment.

The Innovation Sweet Spot

When the organisation's goals are met, the user's desires and needs are addressed, and  the resources available are taken into consideration, the best solutions will be found.


This intersection is called the Innovation Sweet Spot. Viable, desirable and feasible solutions present the best opportunities for innovation.


The 3E Sweet Spot


Empathy is a core principle of design thinking and sustainable problem solving. The needs of end user are always at the heart of the decision process.


Efficacy measures the impact of the intervention for users and the return on investment (time, people, money.....) for the resources used.


The solution allows all parties (business, customer, community, citizen....) to believe that they have been truly enabled.

Developed by InterroBang the 3E Sweet Spot is used to audit decision solutions to ensure they meet the client's and users' requirements before the solution is launched.

Decision Skills Chain

The Decision Chain was developed by the Decision Education Foundation a non-profit education company in San Francisco, California.

This model places equal emphasis on logic and emotion (head and heart). Solutions designed with the Decision Chain make sense and feel right, consequently are easy to commit to action.

As with Design Thinking the process is iterative and each of the 6 elements can be revisited until the decision maker is confident that they have the optimal solution.

InterroBang is proud to be the Decision Education Foundation's volunteer of the year 2020.
