The review of the ideas in Richard Koch's book: "The 80/20 Principle" shows that 80-percent of the results in any system will flow from just 20-percent of the efforts. Trying to eliminate the 80 percent is usually ineffective; therefore, try to expand the 20 percent. This summary highlights 10 techniques for increasing productivity in the 20 percent,  and explains why they are valuable. For example, it suggests businesses should focus marketing on their top 20 percent of products. Understand that only 20 percent of decisions will be the vital ones, and act accordingly. 20 percent of every salesforce will be the best: analyse and comprehend why this is so, and act accordingly. In negotiation, remember that again, you are probably only disputing about 20 percent of the issues being discussed: it’s in your interests to always be aware of this.
