part of an ongoing effort to keep you informed about our latest work,
I'd like to let you know about some recently published SEI technical
reports and notes. These reports highlight the latest work of SEI
technologists in information assurance and agile, the Team Software Process (TSP), CERT secure coding standards, resource allocation, fuzzing, cloud computing interoperability, and cloud computing at the tactical edge.
This post includes a listing of each report, author(s), and links where
the published reports can be accessed on the SEI website.
Part 1: Software Sustainment Trends and Challenges
By Douglas C. Schmidt,
Deputy Director, Research, and Chief Technology Officer
of Defense (DoD) programs have traditionally focused on the software
acquisition phase (initial procurement, development, production, and
deployment) and largely discounted the software sustainment phase
(operations and support) until late in the lifecycle. The costs of software sustainment are becoming too high to discount since they account for 60 to 90 percent of the total software lifecycle effort.
Moreover, in an era where DoD new-start programs are being reduced in
favor of prolonging legacy systems, significant software sustainment
cost increases are themselves unsustainable. The growing expense and
prolonging of legacy systems motivates the need for greater discipline
and attention on defining and applying appropriate methods and
technologies to improve sustainment capabilities and efficiencies. This
SEI blog posting—the first in a two part series—summarizes key
software sustainment challenges faced by DoD; the subsequent post
describes R&D activities conducted by the SEI to address some of
