Using Quality Attributes as a Means to Improve Acquisition Strategies

Lisa BrownswordAlthough software is increasingly important to the success of government programs, there is often little consideration given to its impact on early key program decisions. The Carnegie Mellon University Software Engineering Institute (SEI) is conducting a multi-phase research initiative aimed at answering the question: is the probability of a program’s success improved through deliberately producing a program acquisition strategy and software architecture that are mutually constrained and aligned? Moreover, can we develop a method that helps government program offices produce such alignment? This blog post, the third in a series on this multi-year research, describes our approach to determining how acquisition quality attributes can be expressed and used to facilitate alignment among the software architecture and acquisition strategy.

Reducing Project Failures by Aligning Acquisition Strategy and Software Architecture with Stakeholder Needs

Lisa BrownswordMajor acquisition programs increasingly rely on software to provide substantial portions of system capabilities. All too often, however, software is not considered when the early, most constraining program decisions are made.  SEI researchers have identified misalignments between software architecture and system acquisition strategies that lead to program restarts, cancellations, and failures to meet important missions or business goals. This blog posting—the second installment in a two-part series—builds on the discussions in part one by introducing several patterns of misalignment—known as anti-patterns—that we’ve identified in our research and discussing how these anti-patterns are helping us create a new method for aligning software architecture and system acquisition strategies to reduce project failure.

Lisa BrownswordMajor acquisition programs increasingly rely on software to provide substantial portions of system capabilities.  Not surprisingly, therefore, software issues are driving system cost and schedule overruns.  All too often, however, software is not even a consideration when the early, most constraining program decisions are made.  Through analysis of troubled programs, SEI researchers have identified misalignments between software architecture and system acquisition strategies that lead to program restarts, cancellations, and failures to meet important missions or business goals. To address these misalignments, the SEI is conducting new research on enabling organizations to reduce program failures by harmonizing their acquisition strategy with their software architecture.  This blog posting—the first in a two-part series—motivates the problem of misalignment and describes the SEI’s current research for addressing this problem by analyzing program-specific quality attributes associated with business and mission goals.
