New acquisition guidelines
from the Department of Defense (DoD) aimed at reducing system lifecycle
time and effort is encouraging the adoption of Agile methods. There is a
general lack, however, of practical guidance on how to employ Agile methods
effectively for DoD acquisition programs. This blog posting describes
our research on providing software and systems architects with a
decision making framework for reducing integration risk with Agile
methods, thereby reducing the time and resources needed for related
work.

In his book Drive, Daniel Pink
writes that knowledge workers want autonomy, purpose, and mastery in
their work. A big problem with any change in processes is getting the
people who do the work to change how they work. Too often, people are
told what to do instead of being given the information, autonomy, and
authority to analyze and adopt the new methods for themselves. This
posting—the first in a two-part series—describes a case study that shows
how Team Software Process (TSP) principles
allowed developers at a large bank to address challenges, improve their
productivity, and thrive in an agile environment.

Acquisition Support Program
In my preceding blog post, I promised to provide more examples highlighting the importance of software sustainment in the US Department of Defense (DoD). My focus is on certain configurations of weapons systems that are no longer in production for the United States Air Force, but are expected to remain a key component of our defense capability for decades to come, and thus software upgrade cycles need to refresh capabilities every 18 to 24 months. Throughout this series on efficient and effective software sustainment, I will highlight examples from each branch of the military. This second blog post describes effective sustainment engineering efforts in the Air Force, using examples from across the service’s Air Logistics Centers (ALCs).

As
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 embedded systems, risk management, risk-based measurement and analysis, early lifecycle cost estimation, and techniques for detecting data anomalies.
This post includes a listing of each report, author(s), and links where
the published reports can be accessed on the SEI website.

Many DoD computing systems—particularly cyber-physical systems—are subject to stringent size, weight, and power requirements. The quantity of sensor readings and functionalities is also increasing, and their associated processing must fulfill real-time requirements. This situation motivates the need for computers with greater processing capacity. For example, to fulfill the requirements of nano-sized unmanned aerial vehicles (UAVs), developers must choose a computer platform that offers significant processing capacity and use its processing resources to meet its needs for autonomous surveillance missions. This blog post discusses these issues and highlights our research that addresses them.
