Software Engineering Institute (SEI) Podcast Series

Modern mobile devices create new opportunities to interact with their surrounding environment, but their computational power and battery capacity is limited. Code offloading to external servers located in clouds or data centers can help overcome these limitations. However, in hostile environments it is not possible to guarantee reliable networks. Consequently, stable cloud access is not available. Cyber foraging is a technique for offloading resource-intensive tasks from mobile devices to resource-rich surrogate machines in close wireless proximity. One type of surrogate machine is a cloudlet—a generic server that runs one or more virtual machines (VMs) located in single-hop distance to the mobile device. Cloudlet-based cyber foraging can compensate for missing cloud access in hostile environments. One strategy for cloudlet provisioning is VM synthesis. Unfortunately, this method is time consuming and battery draining because it requires large file transfers. In this podcast, researcher Grace Lewis discusses application virtualization as a more lightweight alternative to VM synthesis for cloudlet provisioning. Listen on Apple Podcasts.

The National Institute of Standards & Technology (NIST) reports that inadequate testing methods and tools annually cost the U.S. economy between $22.2 billion and $59.5 billion, with roughly half of these costs borne by software developers in the form of extra testing and half by software users in the form of failure avoidance and mitigation efforts. The same study notes that between 25 percent and 90 percent of software development budgets are often spent on testing. In this episode, SEI researcher Don Firesmith discusses problems that commonly occur during testing as well as his development of a framework that lists potential symptoms by which each can be recognized, potential negative consequences, and potential causes, and makes recommendations for preventing them or mitigating their effects.

In this episode, SEI researcher Bill Novak discusses joint programs and social dilemmas, which have become increasingly common in defense acquisition, and the ways in joint program outcomes can be affected by their underlying structure. Listen on Apple Podcasts.

In this episode, the second in a series by Suzanne Miller and Mary Ann Lapham exploring the application of agile principles in the Department of Defense (DoD), the two researchers discuss the application of the second principle, "Welcome changing requirements, even late in development. Agile processes harness change for the customer's competitive advantage." Listen on Apple Podcasts.

Four experience reports demonstrate how the CERT Resilience Management Model can be applied to manage complex and diverse operational risks.

In this episode, Peter Feiler discusses his recent work to improve the quality of software-reliant systems through an approach known as the Reliability Validation and Improvement Framework. The purpose of the framework is to facilitate early defect discovery and incremental end-to-end validation. Listen on Apple Podcasts.

In this podcast, Joe Elm discusses the results of a recent technical report, The Business Case for Systems Engineering, which establishes clear links between the application of systems engineering (SE) best practices to projects and programs and the performance of those projects and programs. The report clearly shows that projects that do more SE perform better in terms of meeting budgets, schedules, and technical requirements. The survey population consisted of projects and programs executed by system developers reached through the National Defense Industrial Association Systems Engineering Division, the Institute of Electrical and Electronics Engineers Aerospace and Electronic Systems Society, and the International Council on Systems Engineering.

Analysis work by the SEI on data collected from more than 100 independent technical assessments (ITAs) of software-reliant acquisition programs has produced insights into some of the most common ways that programs encounter difficulties. In this episode, Bill Novak and Andy Moore describe a recent technical report, The Evolution of a Science Project, which is based on these insights, and intends to mitigate the effects of both misaligned acquisition program organizational incentives, and adverse software-reliant acquisition structural dynamics, by improving acquisition staff decision-making.
