Clarify Core Functions

The true prupose of a product must always be at the centre of its design. Consumers may accept losing some secondary functionality in order to achieve other benefits, but will not tolerate a product that does not meet its core functions. Consumers will not buy a product for reasons such as sustainability alone, and nor should they. Products must be good in their own right, with factors such as sustainability providing the “icing on the cake”, not the cake itself.

environmental sustainability Pros: The product will be popular and so displace less sustainable products from the market. It will also avoid premature disposal due to poor functionality.
Cons: Some environmental penalty may have to be payed in order to achieve the required level of functionality.
financial sustainability Pros: Products that meet the customers requirements are likely to sell well. They also satisfy the customer and may lead to repeat business.
social sustainability Pros: Customers need are met.
