1.3. Data gathering and evidence and ‘5 Whys’

  • Gathering data and evidence about a problem you want to solve is vital to any attempt to improve performance or quality and is also needed to assess the impact of an improvement.  
  • When gathering data you learn about the area you are aiming to improve and gain a greater understanding of the problem. Data can help to assess if you have a problem but it won’t necessarily explain why the problem exists. 
  • The idea of using 5 whys is to simply ask why something is done as it is. To the response another why is asked. This continues until you drill down to an understanding the basis for an action or process.  
  • Easy to complete but can give a great deal of information.
