Thread Role Analysis

Many modern software systems employ shared-memory multi- threading and are built using software components, such as libraries and frameworks. Software developers must carefully control the interactions between multiple threads as they execute within those components. To manage this complexity, developers use information hiding to treat components as "black boxes" with known interfaces that explicitly specify all necessary preconditions and postconditions of the design contract, while using an appropriate level of abstraction to hide unnecessary detail....

Rapid Lifecycle Development in an Agile Context

Rapid Lifecycle Development in an Agile Context

• SEI Blog

New acquisition guidelines from the Department of Defense (DoD) aimed at reducing system lifecycle time and effort are 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...

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...

In my preceding blog post, I promised to provide more examples highlighting the importance of software sustainmentin 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...

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...

Real-Time Scheduling on Heterogenous Multicore Processors

Real-Time Scheduling on Heterogenous Multicore Processors

• SEI Blog
Bjorn Andersson

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...

Toward Agile Strategic Planning

Toward Agile Strategic Planning

• SEI Blog
Linda Parker Gates

The appeal of Agile or lightweight development methods has grown steadily in the software development community. Having spent a number of years investigating strategic planning approaches, I've recently been thinking about whether Agile principles can be--and should be--applied to strategic planning. This blog post examines the applicability of Agile principles to strategic planning....

Our SEI blog has included thoughtful discussions about sustaining software, such as the two-part post "The Growing Importance of Sustaining Software for the DoD." Software sustainment is growing in importance as the lifetimes of hardware systems greatly exceed the normal lifetime of software systems they are partnered with, as well as when system functionality increasingly depends on software elements. This blog post--the first in a multi-part series--provides specific examples of the importance of software sustainment...
