Software Quality Characteristics 1.0 the test eye

With all due respect, this is the announcement of the perhaps most powerful public two-page document in the history of software testing.
It is an extended re-write of James Bach’s Quality Criteria Categories, and has been developed to 12 categories (CRUCSPIC STMP) and 93 sub-categories for software quality characteristics/attributes/factors/dimensions/properties/criteria/aspects.
This list is not objectively true, and not easy to use for measuring (compare with ISO 9126-1), but you can adapt it to your context and be inspired by it when understanding/creating/reviewing software quality related stuff.

The PDF is available here, and goes under the Creative Commons Attribution-NoDerivates license, as all our Publications.
Use the list to generate test ideas, or to discuss what is important; get inspired by the concept of Charisma (SPACE HEADS mnemonic)
Suggestions for improvements to the list are very welcome!

We will continuously blog about some of the categories (and sub-categories) in order to provide more information and examples of usage.

Nice. What is the L in STMPL standing for?

Rikard Edgren December 3rd, 2010

The L in Bach’s list is for Localizability.
We put it as Internationalization/Localization, as a sub-category of Portability (ported to another language/culture.)

A good start of a list, but I have already found six candidates for extensions…

Capability, Data agnosticism – supports all possible data formats, and handles noise.
Usability, Control – the user should feel in control over the proceedings of the software.
Charisma, Sex appeal – you just can’t stop looking at or using the product.
Charisma, Uniqueness – the product is distinguishable and has something noone else has.
Security, Piracy Resistance – not possible to illegally copy and distribute the software or code.
Testability, Isolateability – the ability to test a part by itself.

[…] came up with an excellent resource to use, to promote additional ideas in your mind maps called the Software Quality Characteristics v1.0.  This truly is an incredible resource to make use of, which will help you pin point gaps and […]
