Aftermarket & Services

Helping clients capture the aftermarket potential—the largest source of untapped value in aerospace and defense—by assessing the installed base opportunity, improving pricing, and optimizing operations


What does it take to win in the aftermarket? The landscape here is much different from new-equipment sales, but many aerospace and defense (A&D) companies have not yet refined their approach for identifying opportunities, targeting customers, pricing spare parts, upselling, or expanding into new geographies.

We have helped clients worldwide capture more value from the aftermarket and recognize the unique challenges in this space. Our global expertise, combined with our proprietary tools, allows us to craft strategies that help clients develop a thriving aftermarket business.

What We Do

Commercial strategy

Our insights can help with sales planning, account management, value pricing, market penetration, and creation of aftermarket-service offering.


We work with clients to improve all operational areas, including sourcing management, general operations, supply-chain performance, and cost optimization for spare parts by applying design-to-value and standardization technique.

Organizational processes and systems

In addition to examining organizational structure, we help clients forecast their talent needs, improve performance management, and develop strong incentives to motivate talented staff.

New growth levers

We help find the best growth opportunities within the aftermarket by looking at all potential sources, including M&A, the provision of new or digitized services, and the creation of new contracts and service models.

Examples of our work

Identifying and capturing opportunities

A defense company was consistently performing below potential for aftermarket service orders because it focused on selling new systems. With our assistance, the client developed digital solutions to identify aftermarket opportunities. It also instituted capability-building programs to improve the aftermarket salesforce, created better commercial campaigns, and optimized inventory and procurement operations for spare parts. To monitor progress, we helped update tracking processes for all commercial opportunities. Our solutions helped increase the client’s aftermarket service orders by more than 40 percent.

Market analysis and insights

An aerospace player wanted to become the top aftermarket services provider in its sector but knew little about the installed base. The company also relied on a “cost-plus” pricing strategy, rather than looking at the perceived value of parts and services to clients. To help the company improve, we developed an analytical model that estimated the size of the aftermarket opportunity. We also helped identify upselling opportunities, optimize spared-parts pricing, and explore geographic expansion. Our recommendations increased aftermarket service revenues for the commercial fleet by over 10 percent within two years, and additional gains are expected.
