A Simple Method for Idea Selection

Meta-ideas lightbulb illustration

When an organization receives many ideas, it can be difficult to determine which ones are the most valuable. One approach to evaluating and selecting the best ideas is to narrow them down to a smaller set of "meta-ideas" which are formed by combining similar ideas.

The goal is often to identify the most creative ideas, which can be evaluated based on both their novelty (or impact) and workability (or implementability). 

However, it is commonly overlooked that there is often a negative correlation between novelty and workability, which means that many highly novel and easily workable ideas may not be selected.

To streamline the process of evaluating and selecting ideas, here is a four-step method that can help select ideas quickly and also ensures that highly novel and easily workable ideas are selected:

Step 1: Evaluate each idea independently based on its potential impact (Im1) and implementability (Im2). A scale of 1-3, 1-7, or 1-10 can be used, depending on the number of ideas being considered. Calculate the Im-Creativity score for each idea by multiplying its impact and implementability scores (i.e., Im1 x Im2).

Step 2: Rank the ideas from highest to lowest Im-Creativity score. Starting with the top-ranked idea, move down the list and identify any other ideas that could be combined with it to create a single meta-idea. Text clustering techniques, such as Latent Semantic Analysis or Topic Modeling, may be useful in finding similar ideas. A text analysis tool like MeaningCloud can help in this process. Continue this process until you have identified 10 meta-ideas for every 1000 ideas in your pool.

Step 3: To identify novel (high impact) ideas that may have been missed, repeat Steps 1 and 2, but this time calculate Im-Novelty as Im1 x Im1 x Im2. Identify 10 novel meta-ideas using this method for every 1000 ideas in your original pool of ideas.

Step 4: To identify easy-to-implement ideas, calculate Im-Usefulness as Im1 x Im2 x Im2. Repeat Step 2 using Im-Usefulness in place of Im-Creativity to rank the ideas. Identify 10 implementable ideas using this method.

Step 5: Examine the set of ideas and eliminate common ideas in the three lists. Replace common ideas with new ideas from the ranked list.

By following this process, it is possible to quickly identify 30 creative, novel, and implementable ideas from a pool of 1000. This method can be a valuable tool for organizations facing the challenge of evaluating and selecting ideas from many submissions without losing novel and workable ideas.

Camelar: AI Product Ideation for Camel Inspired Cars

By Tojin T. Eapen We used AI tools ( chatGPT and Stable Diffusion ) to generate concept cars ("Camelars") that are inspired by camels, which are known for their exceptional ability to survive and thrive in rugged and challenging environments.  We wanted Camelars to ideally include features and capabilities that would allow them to perform well in conditions such as rough terrain, extreme temperatures, and limited resources. For this, we generated the following description of the Camelar, a bioinspired car that borrows from the appearance and characteristics of the camel. Generate an image of a car inspired by a camel, designed for long distance travel through harsh or remote environments. The car should have a spacious and comfortable interior with amenities like a built-in kitchen and sleeping quarters, as well as storage compartments for supplies and equipment. The exterior should feature a rugged and durable design, with features like high ground clearance, all-terrain ti

Empathy and Confrontation in Idea Generation

By  Tojin T. Eapen Successful innovation often involves two key factors: empathy and confrontation .  Empathy, or the ability to understand and share the feelings of others, is important in both art and science. In art, empathy with human subjects allows artists and writers to create relatable works. In science, empathy with non-human entities and abstract concepts allows investigators to understand them deeply and intuitively. The second key factor in innovation is confrontation, or the clash of ideas , perspectives, or reference frames. While empathy and confrontation may seem contradictory, both are essential for successful innovation, and one often leads to the other. According to MIT professor Edward Roberts , innovation is the combination of invention and exploitation. Theresa Amabile defines innovation as the successful implementation of creative ideas within an organization.  The term innovation can be seen as a portmanteau word that encapsulates its own ingredients: in spira

Generative AI for Bioinspired Product Ideation

By Tojin T. Eapen The design of products, processes, and organizations guided by principles observed in living systems can be referred to as " Bioinspired System Design ." In a series of posts, we delve into the potential of generative artificial intelligence (AI) to generate bioinspired product design concepts as a part of the idea management process. Specifically, we will look at how living organisms can serve as inspiration to redesign common products and human artifacts including bags, cars, bags, pens, tanks, trains, and umbrellas. In each of these articles, we will examine how the unique characteristics and behaviors of a particular living organism can be incorporated into the design of the bioinspired product.

The Efficiency-Resilience-Prominence (ERP) Framework

Consider any living organism and its struggle for survival in a changing environment. Three crucial factors are common to all living systems: resource management, especially energy resources; coping with environmental forces such as heat, wind, and currents; and managing relationships with other entities, which can range from friendly to predatory.  These three factors are referred to as survivability concerns. To increase survival, an organism must adapt and manage these concerns, either through biological means like specialized organs, or behavioral means such as action and strategy. Organizations also face these same concerns of resources, forces, and relationships in their quest for survival.  Each living system has three corresponding capability factors: efficiency in managing resources, resilience against environmental forces, and prominence in attracting or evading attention. These three capabilities are collectively known as the ERP factors.
