Because it takes time to resolve inequities, problem solving can be defined as a process we engage in over time. Step by step we chip away at pieces of a problem until we arrive at a solution. We meet pre-requisites that give us the resources to fulfill the requirements that must be accomplished to clear the way to our goal. Or, we change the nature of the forces at work that determine the processes that sustain the inequity, so that it dissolves when its foundation is eroded.
Problem solving requires identifying the source of the inequity and/or the kind of effort that will bring an end to it. Each of these requirements depends upon an accurate assessment of the mechanism that generates the inequity, and therein lies the opportunity for error.
