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.  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.

Strategic Management of Architectural Technical Debt

By Douglas C. Schmidt

Douglas C. SchmidtWhile agile methods have become popular in commercial software development organizations, the engineering disciplines needed to apply agility to mission-critical, software-reliant systems are not as well defined or practiced. To help bridge this gap, the SEI recently hosted the Agile Research Forum. The event brought together researchers and practitioners from around the world to discuss when and how to best apply agile methods in mission-critical environments found in government and many industries. This blog posting, the third installment in a multi-part series highlighting research presented during the forum, summarizes a presentation made during the forum by Ipek Ozkaya, a senior researcher in the SEI’s Research, Technology & System Solutions program, who discussed the use of agile architecture practices to manage strategic, intentional technical debt.

Developing an Architecture-Focused Measurement Framework for Managing Technical Debt

Managing technical debt, which refers to the rework and degraded quality resulting from overly hasty delivery of software capabilities to users, is an increasingly critical aspect of producing cost-effective, timely, and high-quality software products. A delicate balance is needed between the desire to release new software capabilities rapidly to satisfy users and the desire to practice sound software engineering that reduces rework. A previous post described the practice of strategically managing technical debt related to software architecture, which involves deliberately postponing implementation of some architectural design choices to accelerate delivery of the system today and then rearchitecting at a later time. This blog post extends our prior post by discussing how an architecture-focused analysis approach helps manage technical debt by enabling software engineers to decide the best time to rearchitect—in other words, to pay down the technical debt.

Jim McHale This post is the second installment in a two-part series describing our recent engagement with Bursatec to create a reliable and fast new trading system for Groupo Bolsa Mexicana de Valores (BMV, the Mexican Stock Exchange).  This project combined elements of the SEI’s Architecture Centric Engineering (ACE) method, which requires effective use of software architecture to guide system development, with its Team Software Process (TSP), which is a team-centric approach to developing software that enables organizations to better plan and measure their work and improve software development productivity to gain greater confidence in quality and cost estimates. The first post examined how ACE was applied within the context of TSP. This posting focuses on the development of the system architecture for Bursatec within the TSP framework.

Developing Architecture-Centric Engineering Within TSP

Felix BachmannBursatec, the technology arm of Groupo Bolsa Mexicana de Valores (BMV, the Mexican Stock Exchange), recently embarked on a project to replace three existing trading engines with one system developed in house. Given the competitiveness of global financial markets and recent interest in Latin American economies, Bursatec needed a reliable and fast new system that could work ceaselessly throughout the day and handle sharp fluctuations in trading volume. To meet these demands, the SEI suggested combining elements of its Architecture Centric Engineering (ACE) method, which requires effective use of software architecture to guide system development, with its Team Software Process (TSP), which teaches software developers the skills they need to make and track plans and produce high-quality products. This posting—the first in a two-part series—describes the challenges Bursatec faced and outlines how working with the SEI and combining ACE with TSP helped them address those challenges.
