AI-driven Cost Transformation

Traditional approaches to cost optimization are still good hygiene, but today remaining competitive requires AI-driven cost transformation. We address three levels of cost optimization, identifying quick-win and deep-potential opportunities and working toward both simultaneously.


Think of traditional cost trimming methods as pushing down on a balloon - often, this causes another area to bulge because it's not addressing the big picture. This method involves a focus on cutting external spend, especially network, software and contract labor.

An intermediate method, cost substitution, involves operating model substitution usually through outsourcing, global capability centers, and/or AI and automation to drive sustainable cost resets.

The final method is a cost transformation of your business' operating model for agility, resulting in cost transparency. Using zero-based budgeting to stay goal-aligned, AI to accelerate the business, and change management to empower your people, you can continuously optimize costs to stay competitive.

ISG helps you achieve fast, sustainable savings through AI-centered expert advisory, market data and insights, and execution support.

How to Get Started:
A Rapid Cost Assessment

We believe that you can't manage what you don't measure. The first step to achieving optimized costs is knowing where you are mis-aligned with the market and your goals. A rapid cost assessment enables you to understand short- and long-term opportunities and plan to go after them.

Step 1:

We perform a rapid, holistic market assessment of your IT and business functions looking for opportunities in four areas by asking:

technology

Supplier Ecosystem

Can external spend be reduced?

 

technology

AI and Automation

Can technology provide a better solution?

 

technology

Processes & Controls: 

Do you have the right visibility, transparency, decision support and controls?

technology

Operating Model:

Can your operating model be improved to deliver better outcomes at a reduced cost?

 

Step 2: 

We build a transformation roadmap prioritizing your cost optimization opportunities, a business case with an OpEx view, and a future-state operating model design.

Step 3: 

We execute the transformation plan to realize phased savings, leveraging strengths in organizational change management, operating model design, sourcing and market data/research.
