Technology

BCG Expand benchmarks IT spend, cloud adoption, AI readiness, application footprint, and delivery productivity to guide modernisation, vendor rationalisation, and tech-enabled efficiency.

Our Technology Solutions

The Problem

  • ✔Over 60% of total Technology spend remains tied to Run-the-Bank activities, limiting investment in innovation.
  • ✔Excessive RTB expenditure slows automation, digital enablement, and modernisation.
  • ✔Legacy infrastructure inflates costs, hinders scalability, and reduces agility.
  • ✔Fragmented application estates drive orchestration inefficiencies and poor end-to-end visibility.

Client success stories

$1bn+ cost efficiencies identified through optimisation of Change-the-Bank versus Run-the-Bank spend
15–25% reduction in infrastructure costs via estate rationalisation and vendor consolidation.
10–20% faster delivery cycles driven by automation and cloud adoption.

Case Studies

Tier 1 Investment Bank

A Tier-1 Investment Bank rebalanced Change-the-Bank versus Run-the-Bank expenditure, identifying over $1 billion in cost-efficiency opportunities. The savings were redirected into automation and resilience initiatives, delivering measurable long-term value.

Global Markets Institution

20% reduction in infrastructure spend through estate rationalisation and vendor consolidation.

How we can help

Cost Diagnostics

We perform full cost analysis by business, cost type, and driver, supported by raw data captured directly from client MIS systems for accuracy and speed.

Application Landscape

Evaluation of the application estate (on-site vs cloud hosting, average application age, utilisation patterns) to identify consolidation and modernisation opportunities. Legacy infrastructure and fragmented application stacks are benchmarked against peers to highlight rationalisation opportunities and areas for improved agility.

Infrastructure

Analysis of cost per unit across servers, storage, and end-user technology, plus assessment of server distribution and utilisation. Estate-rationalisation insights inform cloud adoption decisions and vendor optimisation to reduce infrastructure expenditure by 15–25%.

The Problem

  • ✔Inefficient resourcing models inflate technology costs and slow delivery.
  • ✔High dependency on contractors and sub-optimal location strategy reduce agility.
  • ✔Complex spans and layers increase cost and limit decision-making speed.

Client success stories

10–20% faster delivery cycles via KPI-driven automation and streamlined delivery governance.
improved development efficiency through best-in-class engineering methodologies.

How we can help

Workforce Benchmarking

We analyse FTE mix, role structure, contract type, and location strategy to optimise team design, strengthen delivery capacity, and ensure scalability and cost efficiency.

Developer Productivity Benchmarking

We benchmark engineering practices and development methodologies to identify opportunities to improve throughput, reduce friction, and enhance overall delivery velocity.

Delivery Governance Review

We evaluate governance structures and delivery workflows to surface bottlenecks, streamline execution, and shorten deployment timelines across technology teams.
