We will first study the ideal final result as an independent tool. We also briefly examine different ways to describe ideal systems.

Second, we will study how to go from the definition of contradictions and resources to the ideal final result. In previous chapters, we defined good solutions as those that achieve the ideal final result and resolve the contradiction using idle resources. This is easy to say but hard to do. To make it easier, we need a systematic method for using resources to remove contradictions. For this, we introduce the concept of the principal resource. In Chapter 3, we described numerous different tradeoffs. In Chapter 4, we showed how to find the inherent contradiction behind the bundle of tradeoffs. In Chapter 5, we made long lists of resources from inside and outside the system. Now we will select a single, primary, most important resource, called the “principal resource.” Other resources are auxiliary. They help the principal resource remove the inherent contradiction. In this chapter, you will learn to construct the ideal final result from principal and auxiliary resources. In Figure 6.1, we review the general model for problem solving.
