Prioritisation • By the end of this session you will be able to: • use a 2 x 2 matrix (eg Difficulty vs Impact) to prioritise change ideas or drivers • Identify opportunities to use Pareto charts, and analyse Pareto charts to generate and prioritise change ideas.

What is a Pareto chart? 80:20
When to use a Pareto chart • When you can categorise items that have the potential to contribute to the improvement you are considering • When you want to analyse data about the frequency of problems

When to use a Pareto chart • When you can categorise items that have the potential to contribute to the improvement you are considering • When you want to analyse data about the frequency of problems • When you have at least 30 observations across the categories (vertical axis) • Consider: measure, period, existing data
Pareto chart examples • For this project, what data could a Pareto chart be used with? • Which driver(s) or change idea(s) is this Pareto chart related to? • Which categories would you focus your improvement efforts on? • What action would you take based on this chart?
Project work: prioritise • Would a Pareto chart be useful for your project? • If so, what data would you need, and how could you get it? • Use the Impact vs Difficulty matrix to identify your top priority for change.
