Shewhart as PDCA cycle, and further developed by W. Edwards Deming into the PDSA that we know today. It provides a rapid way to test out small changes, learn from ideas and establish what does and what doesn’t work.   As PDSA is one of the most commonly used tools in healthcare improvement work, we are refreshing some old learning articles and adding to them new topics like ‘sequential vs. simultaneous PDSA cycles’. Check out a few of the new articles below and don’t miss out on the latest from our Improvement Hero series - Lloyd Nelson, the man behind special cause variation.       | [![sequential PDSA cycle vs simultaneous PDSA cycle](https://blog.lifeqisystem.com/hs-fs/hubfs/sequential%20PDSA%20cycle%20vs%20simultaneous%20PDSA%20cycle.jpg?width=300&name=sequential%20PDSA%20cycle%20vs%20simultaneous%20PDSA%20cycle.jpg)](https://blog.lifeqisystem.com/sequential-pdsa-cycles-simultaneous-pdsa-cycles)   | ## Sequential PDSA vs. Simultaneous PDSA We look at the different types of ‘Plan-Do-Study-Act’ (PDSA) cycles you can use – sequential and simultaneous – and explore the pros and cons of using each methodology to test out small changes and then build on them.
