The SIAM Project Board has decided that a big bang implementation approach is unsuitable for...

Understanding Big Bang Implementation:A big bang implementation approach involves transitioning all service elements simultaneously. This method is swift but high-risk, particularly when dealing with multiple service providers.

Contractual Considerations:Different service providers often have contracts ending at various times. Aligning all these to terminate simultaneously for a big bang approach is challenging and impractical. This mismatch in termination periods means that transitioning all services at once would likely lead to contract breaches, penalties, or service disruption.

Agile Methods Applicability:Agile methods focus on iterative and incremental delivery rather than a single, all-encompassing change. Although Agile could be challenging in a big bang approach, it’s not the primary reason for ZYX's decision.

Service Level Maintenance:Maintaining consistent service levels is critical during any transition. A phased approach ensures better control and less disruption, ensuring continuous service delivery.

Strategic Alignment:Although the preferences of directors and external suggestions (like from SIAMRUS) influence decisions, they are not the fundamental reasons behind avoiding a big bang approach.

Conclusion:The core issue lies in the contractual termination periods, making a phased implementation more feasible and less risky.
