### Your guide to the many names, terms, acronyms and phrases used when talking about delivering process improvement.

**Written by: James Milsom, Head of Marketing**

 

As we speak to leaders and managers in operational excellence roles, we find that one recurring challenge in their improvement efforts is that they want to drive more sustainable ROI from their projects.

Standardization is at the root of the issue preventing teams from supporting their leaders in achieving this. That means a common understanding and approach to improvement methodology in their business.

This begins with language. That's why we've put together this jargon buster with over 50 terms used in the world of operational excellence, business process management, continuous improvement, and beyond.

 

### 3Ms, 5 whys, and 7 wastes

**3Cs  
**Three questions to correct a problem - concern, cause, and countermeasure.

**  
3Ms  
**The 3Ms originate from Toyota's approach to improvement.

They stand for Muda (waste), Mura (overburden), and Muri (un-eveness).

These must be minimized and eliminated for better flow (and thus better customer experience).

 

**5Ss  
**The 5Ss support a continuous improvement culture, embedding the method into the business. They cover:

- Sort
- Set In Order
- Shine
- Standardize, and
- Sustain

**5 whys  
**The 5 whys involves asking five times why a problem/defect happens until you find the root cause.

**7 wastes  
**The 7 Wastes must be reduced to the minimum in your process, covering:

- Transport
- Inventory
- Motion
- Waiting
- Over-processing
- Over-production, and
- Defects

**  
7 tools of quality control  
**A set of data collection and analysis tools:

- Check sheets
- Cause and effect diagrams
- Pareto charts
- Histograms
- Graphs
- Scatter diagrams, and
- Broken line graphs

**80 / 20 rule  
**Meaning that 80% of outcomes originate from 20% of inputs.

 

 

 

### A3, affinity diagrams, and average charts

**A3  
**An A3 piece of paper upon which current and future state value stream maps are drawn - a highly effective tool for process management.

**Abnormality management  
**A core part of eliminating waste, abnormalities must be easily visible in a process to promote swift action. This becomes part of your standard work.

**

**A board that empowers you to see the status of a production system and highlight emerging issues/abnormalities.**

**

**ANOG  
**An analysis technique to organize data from best to worst and identify visual trends (Analysis of Good).

**  
ANOM  
**Like ANOVA, it only addresses the difference of means (Analysis of Means).**

**

**ANOVA  
**A statistical technique to analyze data by dividing the total variation of data into meaningful parts associated with specific sources of variation to test a hypothesis or estimate variance components (Analysis of Variance).

**  
Attribute data  
**One of two values, e.g., yes or no, green or red.

**Average chart        **  
A control chart where the subgroup average, X-bar, helps evaluate a process level's stability.

Originating in Japan in the 1950s and now being adopted worldwide as the de facto Strategy Execution methodology, Hoshin Kanri means “policy management” in Japanese.

The characters use elements of ‘compass’ and ‘direction’, with the obvious implication that you need to know where you are going and a map to get there.

**Katas  
**Katas bring to life small routines through practice, as opposed to learning by memorizing. These are crucial to the Toyota Production System.

The Kata protocol ensures that knowledge and best practice can be transferred to your organization.

Two Katas are fundamental to Toyota’s improvement culture:

- Problem-solving: Here, the focus is on one issue or improvement priority at a time, with the swiftness of problem-solving at the core of the Kata
- Coaching: Improvement is fundamentally bottom-up, achieved through leaders offering guidance on how to resolve problems in the best way

Katas are important for business leaders regarding continual improvement as they are ingredients for a culture of growth and learning.

- Why?
- When?
- Who?

**KPI  
**Business critical values which measure progress towards strategic goals.
