The Steps of Six Sigma DMAIC Quality Improvement Model

Updated on August 12, 2017

The Six Sigma DMAIC Quality Improvement Model follow steps that are explained below:

Define – the step tries to identify who the clients are, what they need, the process and the capabilities and provides goals for project-based improvement efforts. For instance, improve patient satisfaction, reduce average patient waiting time

Measure – the steps measures and evaluates the characteristics that indicate improvement in customer satisfaction and provides metrics of data that the development will be based on. For instance, the hospital should come up with a quantifiable Lower and Upper Control limits the average level of performance indicator of patient satisfaction against which performance can be measured

Analyze – the step analyses the data collected by applying analytical tools like process flow diagram, fishbone diagram, and alterations necessary to achieving customer satisfaction and performance goals.

Improve – in this process, the resource is allocated to the in to achieve essential change that would result in customer satisfaction.

Control – the step monitors the modification process using quality management tools such Pareto charts, and statistical process control charts with a bid to ensuring that performance improvements are on the right track.

According to McCormack (2004), the concept of PCC (patient-centred care) has become popular in the recent past, to the extent that it has exerted considerable influence on medical practitioners, academics, and policymakers. He asserts that the core components of PCC nursing are:

• Relationship – how a nurse relates to the patients is crucial for the success of Patient-Centred Care.

• Social world – this is the ability by the healthcare organizations to create a caring atmosphere that would be suitable for the patients’ recovery.

• Place – the evaluation of the environment and come up with the best way, to ensure that it provides a Patient- Centred care excellently. It could touch on things like decision-making, staff relationships, risk taking, etc.

• Self – under this, respect for personal value is the key to patient-centred care.

According to Revere and Black, (2003) Six Sigma can achieve tremendous quality improvement because it reduces variation in systems processes. The program would recognize an error in the programme and hence force the administrator to come up with ways of addressing the errors raised by it. The accountability aspect of the system in addition to its timely interventions of certain issues makes the hospital system serve the patients well. For instance, six sigma works to improve the efficiency of the system through quality analysis and process improvement through identifying a possible error in the system. (Johnstone et al. 2003, 53) asserts that six sigma process can determine on what scale a given process would be able to achieve its objective and measures variance based on the unit defects per million chances.
