For example, if the merger and acquisition event
will take place in the months to come, the fixed-income divisions in both companies will be
merged and their software assets will be consolidated. This conditional event should be addressed
in the service life cycle strategy.
SERVICE LIFE CYCLE SEASONS. And now it is time to uncover what services do during their life
cycles. Life cycle seasons are analogous to seasons on earth. These are timeframes during which
services transform from ideas and concepts to physical entities that are deployed in production
environments.
Services live through two major life cycle seasons: design-time season and run-time
season??”as illustrated in Exhibit 2.8. They are established in the design-time season, in which
they are conceptualized, analyzed, designed, constructed, and tested. These service development
activities yield physical solution services that later can be successfully deployed and transitioned to
run-time environments. In the run-time season??”namely, the production environment??”services
are managed, monitored, and controlled to ensure proper performance and consumption rates.
Services ought to spend most of their life cycle time in the run-time season and less in the
design-time season. Consequently, nearly all service life cycle events??”discussed in the section
