How to define continual improvement? If you have an interest in quality management, you probably already have an answer in mind.
This article will introduce you to this concept and guide you through the principles set by Edwards Deming on how to reduce inefficiencies.
Continual and continuous improvement are two similar concepts. The latter describes a never-ending process, while continual improvement refers to repeated but not uninterrupted cycles.
However, both are associated with ongoing improvement. This means taking incremental steps towards process improvement.
Continual improvement is a process designed to:
The successful implementation of a culture of improvement among your team members will make your company more agile.
You can find the best way to foster improvement over time below.
The Deming Cycle is the best way to sum up its author’s principles: Plan Do Check Act. The PDCA cycle was forged by Dr. Deming in the 90s, as a way to lay the foundations of continual improvement.
For this first step, you should define performance metrics. These should follow the SMART principles. A good KPI should be:
Analysing these metrics will help you construct an evidence-based roadmap. Careful planning before the implementation phase will help you choose the best path to improvement.
You should invite everyone to question the existing processes. Avoiding a stagnating status quo is essential.
After you’ve defined your strategy, it’s time to implement corrective actions to optimize your workflows. This step requires tasks to be assigned and tracked efficiently. You can use project management tools to help you in this task.
It’s better to improve your process by 80% today than by 100% tomorrow. Postponing change would also slow down its beneficial effects.
You should track the KPIs defined during the planning phase to make sure bottlenecks are really reduced by your changes.
Use dashboards to keep an eye on all the relevant metrics to act accordingly.
See for yourself what goes on the field. This way, you can better understand the underlying difficulties that could explain a failure to reach the objectives. This is more efficient than looking for scapegoats.
If there is a gap between your expected breakthroughs and your KPIs, you should once again correct your strategy. Learning from your failures is part of improvement techniques.
Be sure to communicate your decisions to the relevant stakeholders.
Think about how to do it rather than why it can’t be done. This positive attitude will help you think creatively, and will motivate your team.
👉 Our tip: people have natural tendency to focus on the “Do” phase. This is because looking at progress creates a feeling of achievement and satisfaction. However, overlooking the other steps of the Deming Cycle undermines the global success of the continual improvement approach.
The continuous improvement model could be defined as a state of mind. However, for best results, it is important to have efficient methods. Here is a quick look at the different approaches you can choose from, depending on the needs of your organisation.
The Kaizen Method advocates for incremental improvement based on questioning the status quo. It relies on collective intelligence and collaboration.
The Ishikawa diagram or 5M method is useful for identifying inefficiencies. It is often used in business process management.
The 5S Method was designed by Toyota engineers to improve working conditions. It has five founding principles:
The Lean Six Sigma method is great if your work is based around projects. It is complementary to other lean management methods such as DMAIC.
DMAIC stands for the five steps of an efficient continual improvement approach for managers:
The just-in-time method comes from the logistics sector. It is based around the 5 zeros:
The agile methodologies family tree is sprawling. All of them are based on implementing iterative improvements and progressive change. You can find a summary of all these different methods in the table below to help you decide.
Method | Principles | Company Type |
Kaizen Method | Collaboration & team intelligence | All |
5M or Ishikawa Diagram | Identifying the root cause of the problem | All |
5S | Rearranging the workplace for better workflows | All |
Six Sigma, DMAIC | Customer reviews, structured problem solving | All |
Just-in-time | Zero waste, zero inventory | Industrial production, logistics |
It is up to you to choose the right one for your needs according to your current workflows and trade. You can take the following steps to find the best fit.
Continual improvement takes time. It is based around small, incremental changes that could seem insignificant at times. However, your team can benefit from both breakthrough improvements, as well as smaller ones.
Sustained efforts towards performance are the best way to nourish the right mindset. Your team and business as a whole will benefit from questioning existing processes.
While there are many paths to positive change, all require looking for the root cause of problems with a thorough data-driven analysis.
