SIAM Modelling

In today’s multi-supplier environments, managing complexity isn’t optional

it’s essential. Service Integration and Management (SIAM) provides the blueprint for aligning multiple providers, internal teams, and partners into a single, coherent delivery ecosystem.

iCore’s SIAM Modelling service helps you define and implement a working integration model tailored to your culture, capabilities, and strategic goals.

Why Choose Us?

SIAM isn’t a one-size-fits-all solution. Without a tailored model and clear roles, it can create more confusion than clarity. At iCore, we draw on deep experience across public and private sectors to help you design a SIAM model that delivers genuine accountability, end-to-end control, and improved service outcomes.

This service is ideal if:

  • You’re operating with multiple suppliers and facing coordination or ownership challenges

  • You’re considering outsourcing or re-tendering and want to future-proof your model

  • You’re seeking better visibility, performance management, and value for money across your supplier base

  • You need a governance model that enables, not hinders, innovation and delivery

    Frequently Asked Questions

    How long does a typical SIAM Modelling engagement take?

    Depending on the complexity of your supplier landscape and how far along you are, engagements usually last between 4 and 12 weeks. We scale our involvement based on need — from short diagnostic reviews to full model design and implementation support.

    Can this work even if we haven’t outsourced yet?

    Absolutely. In fact, modelling your SIAM structure before engaging suppliers puts you in a stronger position. It ensures future contracts and governance frameworks are aligned from the outset, reducing friction and cost later on.

    What if we already have multiple suppliers in place?

    Many clients come to us mid-journey. We help assess your current integration challenges, redesign roles and interfaces where needed, and build a practical roadmap to evolve your model without causing disruption to current operations.

    Is this just about governance, or will it affect day-to-day delivery?

    SIAM impacts both strategic and operational layers. While governance is a core pillar, the model also drives how teams collaborate, how services are supported, and how suppliers are held accountable. Done well, it enhances delivery agility and responsiveness.

    How does this help us improve performance and value for money?

    A clear SIAM model enables proactive performance management, more effective escalation handling, and data-driven decision-making. It reduces duplication, clarifies accountability, and allows you to extract greater value from each supplier relationship.
