Why have the tools of quality come into existence?

Lately we have seen the character of companies and their needs transformed significantly. Production is no longer solely about iron processing or turning out electronic components. Software design, information processing, working with ideas have been taking ever bigger chunk of the total production. Simply put, the soft data is taking the center stage and it needs to be combined with the hard data (measurable). In order to achieve this we are supposed to utilize new methods in the sphere of the quality improvement. Such a need is fulfilled by the 7 new tools of quality. 

In brief, the reasons for the 7 tools might be summarized as follows: 

  • to express thoughts, ideas, views
  • to find links and relationships of importance 
  • to detect similarities and affinities 
  • to express causal relationships 
  • to visualize detected relationships  
  • to work in a team of experts 

Nowadays, proving the quality is there is not enough. A continuous quality improvement appears to be the norm. Finding new possibilities for the company to develop and for their products to be improved is essential. 

Here are the fundamental tools to improve the company´s quality: 

Tool / method of quality  Purpose, function of method 
1. Affinity chart to get orientated in the huge volume of data 
2. Relationship chart to grasp the relationships among the data and identify the important ones 
3. Tree chart to simplify a great problem into elements that are easier to resolve 
4. Matrix chart to better the arrangement of data and its relationships for further processing 
5. Matrix analysis chart  to detect relationships in well-arranged data 
6. Network chart  resource planning in time, looking for an optimal way 
7. PDPC chart to identify the critical spots as early as the planning stage and find countermeasures 

Application of the 7 new tools of quality  

The tools can be used independently or all at once. It depends on the type of company and the particular problem that is being resolved. Anyway, detecting the causal relationships makes the core of every problem-solving. Even the detectives do just this. It is the charts which can put them on the right track, helping them uncover the many relationships among the subjects.  

Today, these tools can also find their uses in the following spheres:

  • software companies
  • new product development
  • marketing and Public relations
  • and so on ... 

Using these tools is not altogether trivial. It requires a thorough preparation and the knowledge how to apply the method correctly. I heartily recommend trying smaller-scale, simpler cases before you begin working on the problem itself. Practical problems tend to be markedly more complex and making mistakes always comes at a price. They are simply more expensive. 

The 7 new tools of quality are focused on working with the so-called soft data. If you need to work with the hard data, use  7 tools of quality

As kids, we had dreams. We would build castles in the air and want to change the world. At least a tiny bit of it. All this was born of our thoughts and when we tried to make them happen they became the reality. Do not let our thoughts die owing to our inaction, and make our dreams come true.
