What is process improvement?
Process improvement involves the business practice of identifying & analyzing the improving existing business processes to optimize performance, meet best practice standards or simply improve the quality and the user experience for customers and end-users.
Process improvement can have several different names such as business process management (BPM), business process improvement (BPI), business process re-engineering, continual improvement process (CIP), to name a few. Regardless of the nomenclature, they all pursue the same goal: to minimize errors, reduce waste, improve productivity and streamline efficiency.
Process improvement techniques
There are several different methodologies designed to help your organization tackle process improvement. Each aims to help any business identify process issues, fix them and analyze the success or failure of those systems.
Despite that common goal, each methodology suits a different need. Some frameworks focus on the lean process can improvement techniques; others focus on getting your company culture in the right place for process improvement. There are also some methodologies that help companies visually map out process workflows.
Kaizen: Kaizen promotes continuous improvement with a strong emphasis on lean and agile practices. Kaizen focuses on improving quality, productivity, and efficiency through small shifts in daily work or corporate culture to foster an environment that doesn’t punish errors or mistakes, but instead works to prevent them from happening again.

5S: The 5S model is part of the Kaizen and Lean methodologies and it stands for five main steps: sort, straighten, shine, standardize and sustain.
The 5S model helps bring more consistency to process improvement and can standardize process improvement.
PDCA: Also part of the Kaizen methodology, PDCA stands for plan, do, check and act. It helps organizations be more efficient when identifying processes that need improvement. You first identify the problem (plan), create and implement a solution (do), evaluate data for effectiveness (check) then document the final results and implement the plan if it’s successful (act).
Six Sigma: Six Sigma is a popular process improvement methodology that pulls workers up through ranks classified using karate belts. You start as a green belt and learn your way up to a black belt. Six Sigma involves two ways to break down process improvement through specific steps. These steps include define, measure, analyze, improve and control (DMAIC) and define, measure, analyze, design and verify (DMADV).
Cause and Effect Analysis: Another tool born from Six Sigma is Cause and Effect Analysis, which involves using a diagramming method to fix problems the first time by identifying the problem, discovering roadblocks and pinpointing why the process isn’t working.
SIPOC analysis: As a diagram format that falls under the Six Sigma methodology, SIPOC analysis happens during the “measure” stage of DMAIC or DMADV. SIPOC helps organizations define and establish a process improvement project as well as identify requirements and necessary elements before starting.
Value stream mapping (VSM): VSM helps organizations visually represent customer’s perceptions of a business process, which helps identify the value of a product, process or service to the organization. Similar to other methodologies, it’s highly focused on eliminating waste, redundancy and being as lean as possible.
Total Quality Management (TQM): Focused on cultivating long-term success through customer satisfaction, TQM helps organizations get the entire company on board with continuous process improvement. It’s a methodology that empowers workers by fostering a culture where employees aren’t afraid to make mistakes and are driven towards a shared business goal.
Kanban: Kanban is a tool for process workflow visualization that gets business units, leadership and employees on the same page for process improvement. It’s another methodology that incorporates and encourages the lean process to improve business Systems.
Process mapping: Another workflow visualization that helps companies map out a plan for process improvement is process mapping. It can also be called a process flowchart, process chart, functional flowchart, and process model. Ultimately, it’s the process of creating a flow diagram that delivers vital information about a process workflow from start to finish.
