What Is the 80-20 Rule The 80-20 rule, also known as the Pareto Principle, is a familiar saying that asserts that 80 of outcomes (or outputs) result from 20 of all causes (or inputs) for. The most votes is represented by the highest frequency (the first bar) in the Pareto chart which is 'Routine bloods not collected'. The example in Figure 2 (below) shows a Pareto Chart of team votes.Īfter a brainstorming session a team has voted on what they believe most contributes to patients not being prescribed the correct anticoagulant dose. In that case, 20 of the workers did 100 of the work. However, some of the 'trivial many' factors may be simple to address (low hanging fruit) and therefore may be acted upon earlier rather than later. Think about it in a group of 100 workers, 20 could do all the work while the other 80 goof off. The types of medication errors that fall above the 80% cut off line are known as the 'trivial many' and are generally seen as not a high priority to address when compared to the 'vital few' factors. The types of errors that fall under the 80% cut off line indicate the 'vital few' types of medication error that should be addressed as a priority as they contribute most to the problem ie: It is implemented in the Wolfram Language as ParetoDistribution k, alpha. The results were collected initially in a Tally Sheet then the data was placed in descending order of frequency in a Pareto Chart Template in Excel. An audit of 430 medication errors was conducted to determine the categories (types) of errors and their frequency. The example in Figure 1 (above) shows a Pareto Chart of types of medication errors. It also helps a team communicate the rationale for focusing on certain areas. Using a Pareto diagram helps a team concentrate its efforts on the factors that have the greatest impact. cumulative per cent dots that fall above the 80% cut off line). The value is the shape parameter of the distribution, which determines how distribution is sloped (see Figure 1). factors whose cumulative per cent (dots) fall under the 80% cut off line) from the 'trivial many' (factors that, while useful to know about, have a relatively smaller effect i.e. The Pareto distribution is a power-law probability distribution, and has only two parameters to describe the distribution: (alpha) and X m. The ordering in a Pareto Chart helps identify the 'vital few' (the factors that warrant the most attention i.e.
