To ensure that ZOY Pharmaceutical is managed and maintained with the greatest efficiency, ZOY IT staff must keep its hardware and software systems up and running on a $24$x$7$ basis. ZOY implemented the ITIL framework three years back. It helped the organisation's service desk to respond quickly to incidents. Furthermore, the group conducted software application rollouts and upgrades that effectively reduced long$-$term costs and promoted flexibility within its computing environment that support future business growth. To achieve the next level of ITSM objectives you are appointed as the CSI manager. Some of these objectives given to you include verifying that measurement and metrics are in place and that milestones were achieved, process compliance is high, and the business objectives priorities were met by the level of service. Finally, your suggested approach should ensure that the momentum for quality improvement is maintained by assuring that change becomes embedded in the organization. As a CSI manager, before you implement any initiatives, you need to understand the role of other lifecycle stages within ZOY Pharmaceutical.
