Agile projects with incremental development lifecycles are showing greater promise in enabling organizations to rapidly field software compared to waterfall projects. There is a lack of clarity, however, regarding the factors that constitute and contribute to success of Agile projects. A team of researchers from Carnegie Mellon University's Software Engineering Institute, including Ipek Ozkaya, Robert Nord, and myself, interviewed project teams with incremental development lifecycles from five government and commercial organizations. This blog posting summarizes the findings from this study to understand key success and failure factors for rapid fielding on their projects.
The power and speed of computers have increased exponentially in recent years. Recently, however, modern computer architectures are moving away from single-core and multi-core (homogenous) central processing units (CPUs) to many-core (heterogeneous) CPUs. This blog post describes research I've undertaken with my colleagues at the Carnegie Mellon Software Engineering Institute (SEI)--including colleagues Jonathan Chu and Scott McMillan of the Emerging Technology Center (ETC) as well as Alex Nicoll, a researcher with the SEI's CERT Division--to create a software library that can exploit the heterogeneous parallel computers of the future and allow developers to create systems that are more efficient in terms of computation and power consumption.
Department of Defense (DoD) program managers and associated acquisition professionals are increasingly called upon to steward the development of complex, software-reliant combat systems. In today's environment of expanded threats and constrained resources (e.g., sequestration), their focus is on minimizing the cost and schedule of combat-system acquisition, while simultaneously ensuring interoperability and innovation. A promising approach for meeting these challenging goals is Open Systems Architecture (OSA), which combines (1) technical practices designed to reduce the cycle time needed to acquire new systems and insert new technology into legacy systems and (2) business models for creating a more competitive marketplace and a more effective strategy for managing intellectual property rights in DoD acquisition programs. This blog posting expands upon our earlier coverage of how acquisition professionals and system integrators can apply OSA practices to decompose large monolithic business and technical designs into manageable, capability-oriented frameworks that can integrate innovation more rapidly and lower total ownership costs.
As part of an ongoing effort to keep you informed about our latest work, I would like to let you know about some recently published SEI technical reports and notes. Three of these reports highlight the latest work of SEI technologists on insider threat in international contexts, unintentional insider threats, and attributes and mitigation strategies. The last report provides the results of several exploratory research initiatives conducted by SEI staff in fiscal year 2012. This post includes a listing of each report, author(s), and links where the published reports can be accessed on the SEI website.
