The information flow on the left side of the "V" is ensured through a base practice "Communicate agreed ‘work product x’". The term "agreed" here means that there is a joint understanding between affected parties of what is meant by the content of the work product.
The information flow on the right side of the "V" is ensured through a base practice "Summarize and communicate results". The term "Summarize" refers to abstracted information resulting from test executions made available to all relevant parties.
Note that these communication-oriented base practices do not necessarily require a formal approval, confirmation, or release as rather targeted at by GP 2.1.7 on capability level 2. At capability level 1 the communication-oriented base practices mean that the work products (or their content) are to be disseminated to relevant parties.
