Driver Diagrams

Introduction

A driver diagram is a simple but powerful improvement tool. It is a concise, visual description of the contributing or “driving” factors that lead to the ultimate goal of an improvement project. Consisting of an overall aim, with associated primary and secondary drivers, the driver diagram demonstrates how different factors logically contribute toward achieving the aim. Collaboratively created and widely shared, a driver diagram can be an excellent way of communicating the overall strategy of a project and serve as a point of reference for teams to ensure efforts are occurring in the key areas related to the stated goal. A driver diagram illustrates the theory of change for an area of improvement, and if the theory is sound, the change ideas that address the primary and secondary drivers will lead to improvement.

Why make a driver diagram?

• ▪

  To clarify the key factors or “drivers” that underpin your aim

• ▪

  To create a visual improvement strategy

• ▪

  To help communicate your theory of change

Creating a Driver Diagram

Creating a driver diagram starts by gathering a team of people (often termed “stakeholders”) who have a good understanding of the current system. Involving staff from a variety of roles will bring different information and perspectives to the topic. This diversity will lead to a more coherent and comprehensive understanding of the system and the factors that underlie an improvement goal. Ideally, in projects focused on improving patient care, a patient representative should be included in the stakeholder group.
