Case Study 2: CVS Health DevOps Transformation

Unifying Two Companies Through Enterprise Tool Modernization

At a Glance:

Organization: CVS Health (post-Aetna merger)
Role: Product Owner → Product Manager (promoted mid-project)
Timeline: October 2021 - October 2024
Scale: 3,000+ developers across two merged organizations

The Challenge

Following CVS Health's acquisition of Aetna, developers faced a nightmare scenario with completely incompatible tool stacks that severely hindered collaboration:

Aetna Tool Stack:

Harness, CircleCI, outdated GitHub Enterprise, legacy SVN
Unreliable, outdated Nexus instance
Additional tools like Quay creating complexity

CVS Tool Stack:

Jenkins, locally installed GitLab, another unreliable Nexus
Local MacOS hardware for iOS builds

Critical Access Problem:

Double VPN requirement - CVS developers needed one VPN to reach CVS network, then second VPN to access Aetna tools
Zero collaboration between development teams across companies
Frustration and inefficiency across entire development organization
Fragmented workflows preventing enterprise-wide development practices

The merged organization needed unified, modern tools accessible to all 3,000+ developers without network barriers.

My Strategic Approach

Phase 1: Platform Transformation (Product Owner Role)

Operational analysis - Became intimately familiar with platform pain points through Platform Demons team
Proactive service model - Transformed team from reactive "ticket factory" to proactive monitoring and issue resolution
Jenkins optimization - Reduced error rate by 75% through new hardware and workflow cleanup
Demonstrated value - Earned promotion to Product Manager based on transformation results

Phase 2: Enterprise Tool Strategy (Product Manager Role)

Architecture alignment - Worked with Architecture and Engineering Leadership to select unified tool stack: Harness, CircleCI, GitHub Enterprise Managed Users, JFrog Artifactory
Access solution - Championed elimination of dual-VPN requirement through single enterprise toolset
Vendor partnerships - Personally worked with each vendor to establish OKRs, metrics, and targets

Phase 3: Organization-Wide Implementation

Communication strategy - Led town halls with 600+ attendees to advertise plans, progress, and action items
Contract negotiation - Facilitated 6-month negotiation between CVS and JFrog to bring best-in-class Artifactory
Budget management - Managed procurement budgets ensuring no surprises for leadership
Executive reporting - Presented OKRs, metrics, and trends to senior leadership throughout transformation

Phase 4: Migration & Adoption Management

Tiger team structure - Led focused team with 2 developers per tool, 1 architect overseeing implementation
Customer Success innovation - Created first-ever Customer Success Team for personal attention and hand-holding during migrations
Adoption strategy - Managed transition through town halls, action items, and strategic sunsetting timelines
Timeline execution - 6 months to go-live, additional 9 months for complete organizational transition

Technologies Implemented: Harness | CircleCI | GitHub Enterprise Managed Users | JFrog Artifactory | Enterprise Access Management

Key Learnings & Insights

Complex transformations require both technical and cultural solutions. The dual-VPN problem wasn't just technical—it was preventing cultural integration between CVS and Aetna teams. Solving access enabled collaboration that transformed how the merged organization operated.

Customer success makes or breaks large-scale migrations. Creating the Customer Success Team was crucial for adoption. Developers needed personal attention during the transition, not just documentation. This team's continued existence proves its value.

Vendor relationships are strategic partnerships. The 6-month JFrog negotiation taught me that enterprise tool selection isn't just procurement—it's about building partnerships that enable long-term platform evolution.

Communication scales impact. The town hall model with 600+ attendees created organizational buy-in and transparency that made the transformation feel collaborative rather than imposed.

Leadership through service. Transforming from "ticket factory" to proactive platform support changed how developers perceived the platform team—from obstacle to enabler.
