Esma Elmazaj and Pat O’Reilly on Creating a Powerhouse of Innovation

IMO Leadership Profile

How will our shared culture of innovation and operating philosophy create a stronger platform to drive growth for our planned merger?

Both L3 and Harris are technology-driven organizations with significant R&D investment and a combined workforce of approximately 19,000 engineers. L3 has approximately 10,500 and Harris has almost 8,500 engineers. The combined company will have the opportunity to accelerate investment in select technologies to expand leadership in key strategic domains.
The Integration Management Office (IMO) Engineering Functional Integration Team must develop the plans, processes and systems to achieve a flawless coming together of this powerhouse of innovation.    

Esma Elmazaj, Senior Director of Engineering at Harris Corporation, and Patrick “Pat” O’Reilly, Vice President of Engineering at L3, the IMO Engineering Leads, are spearheading the integration planning for their function to help realize the promise that 1 + 1 is bigger than 2.

“The two companies share a mutual commitment to innovation and technology. That is truly exciting for engineers who want to create solutions that address critical challenges. And this opportunity to solve meaningful problems is just going to get bigger after we merge.” O’Reilly says.

Prior to joining L3, O’Reilly worked in Silicon Valley in an engineering start-up company. Previously, he was the Director of the U.S. Missile Defense Agency (MDA), overseeing all U.S. missile defense programs. During his service in the Army, O’Reilly was the project manager for various high-profile programs including Patriot Advanced Capability-3 (PAC-3), Ground-based Midcourse Defense (GMD) Terminal High Altitude Area Defense (THAAD) Missile Defense Systems and was the Program Executive Officer (PEO) for combat service support.

“I am most excited that we have the opportunity to solve the new problems that are facing our customers,” O’Reilly says. “I can see the potential for breakout technologies.”

O’Reilly’s IMO lead partner, Esma Elmazaj was Engineering Director at BAE Systems, a defense contractor supplying to militaries and governments, where she held various engineering leadership positions from executing programs working as a functional lead to developing technology roadmaps and helping create new opportunities through winning many Contractor Research and Development contracts. Elmazaj also has a 16-year background in the commercial sector working in various leadership positions at Ford Motor Company taking products from idea to mass production.

“Engineers are at the core of Harris and L3 technologies and they will be a driving force for innovation. Each engineer has something to contribute to this merger,” Elmazaj says. “We should all be excited for the innovation and opportunities to come.”

To achieve a seamless integration, Elmazaj and O’Reilly are exploring improved methods of communicating and developing an integrated engineering management model that empowers engineers and enables the growth they are anticipating. This includes an improved ability for collaboration with other functions, like Operations. O’Reilly and Elmazaj are leveraging ways to enhance access to the combined intellectual capital of 19,000 L3 Harris engineers.

“With the planned Day 1 implementation of improved channels of communication for engineers, we will make the engineers knowledgeable about what each organization brings, both in opportunities and capabilities,” O’Reilly says.

“We would like to integrate as rapidly as we can post closing, but at the same time, we want to maintain continuity. Our goal must be to satisfy our customers as we progress, transition and make the changes necessary to realize the full value of our capabilities as it makes sense for the business.”

As the integration moves forward, both Elmazaj and O’Reilly see the potential for our engineers to develop future technologies by combining core capabilities from each company. And their advice… “embrace the mission-solution mindset – get excited and be ready for innovation and growth.”
