The use of process mapping in healthcare quality improvement projects. 
Introduction Process mapping provides insight into systems and processes in which improvement interventions are introduced and is seen as useful in healthcare quality improvement projects.  There is little empirical evidence on the use of process mapping in healthcare practice.  This study advances understanding of the benefits and success factors of process mapping within quality improvement projects.  Methods Eight quality improvement projects were purposively selected from different healthcare settings within the UK's National Health Service.  Data were gathered from multiple data-sources, including interviews exploring participants' experience of using process mapping in their projects and perceptions of benefits and challenges related to its use.  These were analysed using inductive analysis.  Results Eight key benefits related to process mapping use were reported by participants (gathering a shared understanding of the reality; identifying improvement opportunities; engaging stakeholders in the project; defining project's objectives; monitoring project progress; learning; increased empathy; simplicity of the method) and five factors related to successful process mapping exercises (simple and appropriate visual representation, information gathered from multiple stakeholders, facilitator's experience and soft skills, basic training, iterative use of process mapping throughout the project).  Conclusions Findings highlight benefits and versatility of process mapping and provide practical suggestions to improve its use in practice.
