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 p
