Inside TIAA’s massive IT transformation to fuel business growth
Executive Take
TIAA proves large IT overhauls survive by tying every phase to a business outcome, not just technology upgrades. Leaders should set honest, staged metrics with their board instead of overpromising fast returns.
Executive Summary
TIAA's multi-year TETRIS program, led by CIDO Sastry Durvasula since 2022, modernized legacy IT via cloud and AI. Phase one (2023) added 10 enterprise platforms; phase two (2024) enabled 87 business use cases, cut tech debt nearly in half from over 80%, sped product launches 35%, and added multilingual access for 185,000 customers.
Why It Matters
Technology leaders get a rare, detailed playbook for running a multi-year transformation without losing board support. HR leaders should note the deliberate change management push tied to reskilling, not headcount cuts.
Bizquad Perspective
The real lesson isn't the tech stack, it's that Durvasula sold uncertainty to the board upfront, which most transformation leaders avoid doing until something already broke.
