Solution

CME Group uses Gemini Code Assist to accelerate developer tasks and enable its technical workforce to focus on innovation. CME Group the world’s leading derivatives marketplace, has built an enviable reputation for trust and reliability over its 175-year history. However, driven by a culture of innovation, it isn’t resting on its legacy and is on a transformation journey to move nearly all application assets to The ultimate aim of the transformation is to accelerate innovation and product delivery. To achieve this, CME Group wanted to upgrade its technology infrastructure and manage the complexity of migrating from on-premises systems to the cloud while reducing security vulnerabilities. However, CME Group typically approaches new technology adoption cautiously due to strict regulatory requirements and lengthy internal review processes.

Scoring methodology

How scores are calculated

Customer Reference Value measures usefulness as a customer reference. Evidence Confidence measures the quality and traceability of available evidence, not independent verification.

Customer reference value90/100
  • Problem clarity20/20
    Measures whether the customer's operational problem is specific enough to compare.
  • Implementation depth15/25
    Rewards named components, data flow, integrations, and architecture detail.
  • Outcome specificity20/20
    Measures whether the reported benefit is concrete rather than a generic claim.
  • Quantified impact25/25
    3 metrics describe measurable impact.
  • Deployment scale10/10
    Rewards evidence of a live or scaled deployment and meaningful integration scope.
Evidence confidence77%
  • Source authority20/25
    The main evidence is an official vendor-published customer story.
  • Claim traceability21/25
    10 of 12 key fields link to a named source.
  • Direct evidence20/20
    6 direct source quotes retained.
  • Date provenance0/10
