You work for a company that produces a credit-checking software package. This product comes in three variants, each of which is tailored to meet the rules and attitudes of lending and borrowing money for a particular group of countries. Each variant has two different versions at any one time: the current live release and the next release, which is under development. Each variant has its own test environment; these environments are built on different platforms to reflect the diversity of real customer platforms.

A single TAS meets the automation needs of all three variants, with configurable features that allow for the platform differences. The SUT’s test requirements are expanding rapidly and the TAS often needs enhancement to support this. The SUT’s platforms are also changeable, due to updates from their vendors or a desire to sample different ones.

After any change, the TAS is re-installed from a central repository with automated scripts that implement the configuration parameters for the target environment. Following this, it has often been impossible to run tests properly or even at all and the installation has had to be repeated after the cause has been found. Which of the following actions is MOST likely to solve this issue?
