The SIAM Project Board has decided that a big bang implementation approach is unsuitable for ZYX What is the most likely reason for this decision?

The corporate strategy of ZYX contains these objectives: -Ensure delivery against contracts -Invest in and tram all ZYX staff -Reduce operating costs -Be ready to adapt to change The ZYX strategy requires that the costs of the service integrator should be as low as possible, and that service levels and high-quality services should be achieved at all times. The CEO wants the new SIAM model to be in place as soon as possible OUTSCO is a global provider of a range of services, including service integration They have a good reputation as a flexible and reliable service integrator who is willing to amend their SIAM model. They are in the last year of a 10-year contract to provide outsourced services to ZYXUK. Over the last two years the performance and quality of their services has decreased SIAMRUS is a global provider of service integration services in the manufacturing sector They use a standardized SIAM model with limited flexibility SIAMRUS recently created an outline SIAM strategy for ZYXUK: proposing that they should be the service integrator. ZYXS is experienced in the service management of corporate services including managing the delivery of service providers The ZYXS IT Director used to be a senior service manager in a small service integration company The ZYXS office location is almost at capacity with no possibility of expansion ZYXS are the developers of NEWBNK, which is strategic to the future of ZYX The CEO wants to retain as many of the existing service providers as possible Which is the most appropriate structure and sourcing approach for choosing the service integrator for ZYX?

The ZYX Board of Directors decided that the proposal from SIAMRUS for ZYXUK was not suitable to be used for the whole of the group, and asked the ZYXS IT Director to lead the creation of a new SIAM strategy. This new SIAM strategy has now been approved by the NEWGEN Executive Steering Board. What is the best approach to ensure that the ZYXUK Management Board supports the implementation of this SIAM Strategy? 

ZYX has decided on their SIAM strategy and appointed SIAMRUS as the service integrator. The decision has been made to consolidate services into four service groups (in order of proportion of the services) -OUTSCO: service desk, desktop and laptop support services, networking, infrastructure support -ZYXS bespoke application support and development -ZYXD data centers and hosting -BANKSCO: BCT and BNK application support Services from all other current service providers will be transitioned into these service groups as their contracts expire After the service integrator has been onboarded, which of the providers should be onboarded as the first priority? 

ZYX decided to use a phased approach for implementation SIAMRUS was appointed as the service integrator and is now live The next phase is to replace the services currently provided by OUTSCO with services provided by ZYXS, ZYXD, FIELDSCO and NETSCO. This is expected to be completed in 2 months OUTSCO has established a small transition team to assist with the service transfer Over the past 4 months the performance of the OUTSCO service desk has deteriorated, with 50% of calls to the service desk exceeding the call answer time service level OUTSCO has admitted that this is due to reduced numbers of staff on their service desk What is the best approach to address the service level failures?
