Difference between Set-based development and point-based development
1. Point-based Design
Figure 1: Unstable time frame for point-based design
2. Set-based development
Definition: a design, analysis, and decision-making practice characterized by:
-
not selecting a particular values for design decisions but rather analyzing the full set of possibilities, not as a finite collection of a few points, but as an infinite set of points
-
rather than trying to “pick the best”, instead trying to “eliminate the weak”
-
not selecting a particular design and then analyzing its performance, but rather analyzing the drivers of performance and limits on feasibility and using that knowledge to identify more desirable parts of the design space (of the full set of possibilities).
