- Statistical process control (tool)
Statistical process control (SPC) is an analytical technique that plots data over time. It helps us understand variation and in so doing guides us to take the most appropriate action. SPC is a good technique to use when implementing change as it tracks the impact of improvement interventions and enables you to understand whether changes you are making are resulting in improvement.

2. Driver diagram (tool)
Driver diagrams are structured charts of three or more levels. They translate a high level improvement goal/aim into a logical set of high level factors (primary drivers) that you need to influence in order to achieve your goal. They also show the specific projects/activities that would act on these high level factors.
