Some authors such as Michaels (2003) take an even stronger approach, and argue in favor of a strict type of form dependence for sake of protecting the “true innovation of the affordance concept” which lies in “providing the origins of meaning and an experimental inroad for studying it.” Hence, affordances should only be action opportunities directly perceived by the organism for whom the system afford action and “the perception of affordances for others… ought not qualify as the perception of affordances.”

In this paper, we explore the possibility of reconciling and integrating practical affordance- and function-based design representations. We present a classic function-based design method and representation and argue for the benefits of augmenting it with affordance-based approaches. Building on existing function concept ontologies, we present an integrated approach to developing early-stage design representations. This approach combines the use of affordance and function representations to capture user needs across a device's life cycle. We demonstrate how affordances add rigor and expressiveness to the early stages of traditional design processes, and how traditional function-based tools provide affordance-based design (ABD) with structured methods for concept generation. The integrated approach is illustrated with an example, in which a use case is explicitly decomposed to demonstrate the structure of relationships between users, goals, actions, artifacts, functions, and affordances.
