Where is independent quality control–post production?

Here’s something to think about…. In every production process there is an independent quality control check.  For example, a manufacturing line always pulls sample parts during the process and conducts an independent visual inspection.  Software engineers write code, and another group QA’s it.  A writer writes; an editor checks.  In any industry out-of-band quality assurance and feedback loops are fundamental to ensure consistent, repeatable performance and fewer errors.  

In IT what is being “manufactured” is software availability.  But where is the independent check after software is deployed into production?  Configuration and deployment tools are fine, but they only check against themselves.  And we know all too well that applications still fail.

I think the basis methodology of a maker/checker model belongs in IT post production.  Imagine how much more confidence IT Professionals would have in their enterprise if they knew and could prove their software is deployed as intended.

  1. In UAT (User Acceptance Testing) all functionalities will be tested with requirements

    Kumar is correct. The real question is “how can we ensure that the integrity of the stack (manifest and software measurements) is correct over the lifetime of the device within the business process framework?”. Drift from known and desired often begins immediatelyafter the UAT/Deployment occurs. Closing the measurement/attestation gap post -deployment is the key. Undetected change from desired is one of the most significant “open-loop” IT problems to be resolved.
