Focus Initial Efforts on the Critical Subproblems
The goal of all of these decomposition techniques is to divide a complex problem into simpler problems such that these simpler problems can be tackled in a focused way. One problem decomposition is complete, the team chooses the subproblems that are most critical to the success of the product and that are most likely to benefit from novel or creati,•esolutions. This approach involves a conscious decision to defer the ol
subproblems. For example, the nailer team chose to focus on the ubprobl
accepting energy, converting the energy to translational energy, and appling the rran - lational energy to the nail. The team felt confident that the nail handling and triggering issues could be solved after the energy storage and conversionissues were addressed. The team also deferred most of the user interaction issues of the tool. The tea m believed that the choice of a basic working principle for the tool would so constrain the eventual form of the tool that they had to begin with the core technology and then proceed to consider how to embody that technology in an attractive and user-friendly form. Tea ms can usually agree after a few minutes of discussion on which subproblems should be add ressed first
and which should be deferred for later consideration .
