The document discusses a presentation given by Mirco Hering on transformations needed for organizations to adapt to new technologies and ways of working. It covers how principles from manufacturing are misaligned for knowledge work. Three dimensions of change are discussed: organizing knowledge workers, technology architectures, and continuous improvement. Specific topics covered include enabling small batches with technology, evolving architecture models, test automation approaches, and challenges around ecosystem evaluation. The presentation argues organizations need new mental models beyond treating work like a factory to succeed with modern approaches like DevOps.

From…. Quality issues accumulate and are manually
captured at the end …
Transforming to…. Automation and process changes
capture quality issues at the point of origin and enable
faster, more frequent and less costly releases.

From…. Long release cycles, heavy SIT/UAT testing effort,

Transforming to…. Shorter and more frequent release cycles,
greater independence, feature-driven enablement, merged
IT & Business testing.

PEOPLE – TESTING OR QUALITY
It is a mistake to think of test automation as automating what you otherwise would do
manually. You are finding ways to assess the quality of your product in automated ways and
you will execute it way more often than you would do manual testing.
You are not automating testing, you automate the quality assessment.

• Underestimating the impact on infrastructure and the ecosystem
• Underestimating the data hunger
• Not thinking about the system
• Not integrating it into the Software Development Life Cycle
• Test automation is always an afterthought and not baked in as part of the original estimates
– and is hence quite often seen as a additional cost
• Good automation requires good skills – consider the ‘pond’ model
