User Experience
How it is built
We call what the user experiences ‘Perceived Integrity’*.
The way it is built is called‘Conceptual Integrity’*.
*Mary Poppendeick’s ‘Lean SoftwareDevelopment: An Agile Toolkit’
We believe these two concepts are what makes up and define the true meaning
of quality in software.

How - The Quality Wheel
• But what about bugs?!!
• The software doesn’t do what the Customer expects it to do
• Sometimes this is because the Engineer has made a mistake in the coding
• Often, in our experience, it is because the requirements don’t accurately describe what the Customer expects
