Service Integration and Management (SIaM) is widely recognised as a key model for orchestrating multi-supplier IT environments — but successful implementation is rarely straightforward. While the theory is clear, putting it into practice often exposes hidden dependencies, cultural mismatches, and governance gaps that derail even the best-planned transformations.
In this white paper, iCore draws on deep transformation experience to explore what it really takes to implement an effective SIaM model. From the early planning stages to the critical details of supplier transitions and exit strategies, we reveal the success factors, watch-outs, and decision points that shape outcomes.
