What is a pre-requisite/co-requisite relationship of product maintenance and fix releases?
Answer: There are times, a software S1 fix release also requires a fix release of another software S2 because S1 and S2 are related.
An example may be where a change in S1 application requires an additional modification of a feature in S2. In this case the two software S1 and S2 modifications may be considered as co-requisites that must be released together or S2 modification is a pre-requisite that must be available first before S1 change may be released.
