Randy Siegel,a mobile computing executive who has worked with the federal government’s civilian, defense and intelligence agencies on mobile strategies and applications for more than a dozen years, has joined Breaking Gov’s Board of Contributors.

Siegel, who until last month, served as the director of mission critical mobility initiatives at Motorola Solutions, was just named Senior Vice President of U.S. Federal Government sales and strategy for Fixmo, a startup backed by Kleiner Perkins, Motorola Ventures, and other venture capital firms. Fixmo’s mobile risk management technology has been developed as part of a Co-operative Research and Development Agreement (CRADA) with the U.S. National Security Agency.

Prior to Motorola Solutions, Siegel headed up Microsoft Federal’s mobility practice where he architected and implemented some of the largest enterprise mobility deals in the world including work for the United States Postal Service (Service Visibility initiative) and the 2010 U.S. Census with the Commerce Department. Siegel served nearly 12 years with Microsoft and previously has held management positions with MCI Telecommunications and General Electric.

Siegel, who has written articles for Breaking Gov in the past on government mobility issues, will serve as a sounding board on mobile technology and applications in government and contribute commentary articles periodically, said Breaking Gov Editorial Director Wyatt Kash.

“The so-called ‘consumerization of IT’ has turned centralized IT on its head and put IT administrators across the government (and private enterprise) in ‘react mode,'” observed Siegel more than a year ago. That transformation, however, “comes at a cost” for federal agencies, requiring newer models for managing mobile technology.

Siegel has been an active participant in the evolution of mobile technology in the federal government since the late 1990s. At Motorola Solutions, Siegel headed up the company’s Commercial Solutions for Classified (CSFC) go-to-market efforts. Those initiatives included working directly with NSA, DISA, Joint Chiefs of Staff as well as other branches of the DOD and the President’s Community of Interest.

At Microsoft, Siegel had worldwide responsibility for coordinating mobility strategy and tactical deployments with US Government agencies, working with federal agencies as well as with mobile operators, satellite operators, cable multiple system operators, original equipment and design manufactures, software makers, silicon chip manufacturers and solution integrators.

Siegel has been an active member of the Armed Forces Communications and Electronics Association (AFCEA International) and its DC Chapter, and its Mobile Computing Steering Committee, as well as the Northern Virginia Technology Council and other related associations.
