The Future of Agile Configuration Management: 2006 and Beyond


web-based services. Expect vendors of integrated tool-suites (IBM/Rational, Telelogic, Borland, etc.) to expand their offerings of integrated solutions accordingly.

Enterprise CM Integration Architecture - IT architectures and enterprise application integration of CM tools with tools for requirements management, project management, test-management, and their corresponding repositories and reporting mechanisms will abound.

Enterprise Data Management - Enterprise data warehouses ("data marts") will become increasingly more common as a means to both integrate the business-intelligence and decision-support data from multiple disparate repositories and tools while at the same time offloading some of the real-time transactional processing from the native tool/repository to the data-mart.

Web-enabled "CM Services" and Service-Oriented CM Architecture may be utilized to provide "on-demand" CM services [17] for SCM auditing/reporting, status accounting, and traceability via a single web portal serving as an SCM "information radiator" to all subscribed parties and projects. They will also help to ease the customization and deployment of CM solutions for overall decreased "Total Cost of Ownership"

Fast-forward to Model-Driven CM "Factories"
Model-Driven CM will be longer in coming (5-10 years, probably 2010 at the earliest). As Model-Driven Architecture/Development (MDA/MDD) gain more traction, the progression toward " Software Factories " (a perhaps misleading name for a very powerful vision from Microsoft [21]) will become more of a reality. When it does, look for the lines to blur between the modeling environment and the development environment:

Conceptual (rather than Physical) CM entities - Logical/conceptual entities in the UML model (e.g., components, packages, classes, interfaces and methods) will become the primary means of visually navigating through the code, rather than the current predominant use of files and folders/directories. Before long, only CM folks will have to have more than a passing familiarity with how the systems maps into files and folders for optimal build cycle-time and dependency management, and they will be able to use the model and its modeling facilities to track and record dependencies and traceability. So look for Configuration System modeling to become popular once again [22] and finally make its way from research into industry.

Adaptive automated build configuration and optimization - We may then be able let the tools worry about how to perform the translation into files and folders in order to optimize build+test cycle time, and have configuration settings and "profiles" for CM/Builders to tune and tweak to automate computation, display, and tracking of build-dependencies, minimal rebuild/recompilation/relinking, and make a single consistent turnkey mechanism for doing private builds, integration builds, and release builds. This relates to recent build products for distributed builds and build server, ranging from the use of freeware such as Cruise Control, Draco and AntHill, to more commercial tools such as BuildForge, OpenMake, AntHill Pro, and Electric Cloud.

Fine-grained versioning - when conceptual entities become the means of navigating through the code, these finer-grained entities will also become the units of checkout and checkin (see the Stellation subproject of Eclipse [15]). This will decrease the likelihood of checkout contention and merge conflicts, but will increase the need for the greater dependency tracking and analysis that MDA/MDD will enable. This will also demand even tighter integration between the modeling tool and the IDE with each other, as well as with the SCM tools.

Inter-repository integration/unification - currently, different tools and repositories tend to be used for requirements management, design models, and source-code version control. In the short-term, better integration between these different version control repositories will be necessary in order to perform effective change and configuration control. In the longer term, there will be a clamor to be able to use a single object-based repository and integrated database to version
