GBS Design & Build

We design and build GBS organisations from first principles — CFO rigour, operational experience, measurable results.

  • CFO-ready business case with hard NPV, IRR, and payback targets — not indicative ranges
  • Operating model design covering onshore, nearshore, and offshore mix based on your cost, talent, and regulatory profile
  • Location strategy grounded in real operational experience: Poland, Romania, Philippines, India, and APAC markets
  • Governance framework design: SLA architecture, chargeback models, global process ownership, and performance dashboards
