 Understanding the Scenario:

ZYXS will be the service integrator.

OUTSCO, NETSCO, and PAYSCO are the service providers.

PAYSCO provides payroll services and users are satisfied with PAYSCO's services.

The contract with PAYSCO has 2 years remaining, which extends 18 months beyond the SIAM model

implementation.

 Analyzing Constraints:

PAYSCO is unwilling to modify the existing contract to support the SIAM model.

 Evaluating Options:

Option A: Terminating the contract early involves additional costs and may disrupt payroll services,

leading to dissatisfaction among users and potential operational risks.

Option C: Renegotiating contracts with NETSCO and OUTSCO to manage PAYSCO indirectly could

introduce complexity and might not align with the direct relationship PAYSCO has with ZYXS.

Option D: Waiting for the contract to expire is not feasible as it delays SIAM model implementation

and integration benefits for 18 months.

 Selecting the Optimal Approach:

Option B: Implementing an interim operating model allows ZYXS to manage PAYSCO within the

current contract constraints, ensuring continuity of payroll services and gradual alignment with the

SIAM model. This approach maintains user satisfaction and operational stability while working

towards full integration.

 Justification:

An interim model provides a practical solution without immediate contractual changes, leveraging

existing relationships and ensuring service continuity.

This approach aligns with ITIL and SIAM principles of maintaining service quality and managing

supplier relationships effectively during transitions.
