Early Validation Through Models and Simulation

September 2000
RDD.COM Supports Baseline Management of System Engineering Data and Models.

Collaborating teams need tools to help detect technical and process-related defects early in the lifecycle RDD.COM enables teams to meet quality assurance requirements by helping to highlight gaps, inconsistencies, or ambiguities earlier.

To deliver effective solutions more quickly, a team needs to plan for and provide early validation of architectural candidates when changes are less costly and the impact is minimized. RDD.COM provides an optional simulation capability to help teams understand timing as well as resource and concurrency constraints. Executing modeled behavior with RDD.COM allows system designers to determine where logical inconsistencies exist in the design. These types of errors, if first found during actual system operations, can result in loss of life, loss of equipment, and failure to meet mission goals and objectives; in addition they can cost a great deal in terms of time, resources, and customer satisfaction to fix.

With RDD.COM's modeling capabilities, teams can define and establish requirements for data and material flow as well as validate resource needs and understand external and internal interface requirements. Simulation events are depicted graphically as time lines, resource graphs, item (interface) inspectors; and as event transcripts that can be used as test requirements. RDD.COM gives a team the ability to associate each user and system requirement with a verification requirement and method. RDD.COM can be used for test and verification to help plan and define the test environment and support equipment requirements. Process-related data defect analysis is possible through the integrated set of consistency checks; results of these queries are provided on screen, to allow them to work off data inconsistencies.

Baseline Managment and Change Control.

RDD.COM automates change control and baseline management of data and models. Baseline management of the data allows teams to capture the salient characteristics of legacy systems and develop multiple alternatives when system modifications are needed. The rigorous automated configuration management and change control allows teams to control the risks associated when refining requirements.

RDD.COM identifies each requirement and its change history. Its change tracking and control mechanisms do not encumber teams with non-value added change accounting tasks. RDD.COM enforces the process-specific change authorizations determined by the collaborating team, and with its automated baseline management, a collaborating team can be assured of both control and auditable traceability throughout the lifecycle.

Additionally, RDD.COM provides decommissioning teams with the ability to analyze the modified system characteristics to see if re-use of system components can be accommodated.

Simultaneous Change Control for Multiple Users.

Agile collaborating teams need to simultaneous propose changes to requirements without altering previous baselines. RDD.COM track, manages, and controls all proposed changes; the origin and ownership of each requirement is unambiguous and visible for audit purposes.

After team members have completed their changes, they can submit them for re-integration into the proposed baseline. RDD.COM provides for integration and change arbitration and it automatically maintains change authorization levels. Proposed changes and baseline modifications can be annotated by and attributed to an individual team member.

RDD.COM provides support for configuration change control, status accounting, and audit processes by maintaining the status of each object maintained in the repository. An index is available for the baselined project configurations. Engineers can see differences for single elements or groups of elements; they can compare, analyze, and view versions on-line.

RDD.COM stores the data as separate element instances (objects) with the genealogical history of each maintained by the repository. Each object can be related to other objects that represent requirements, issues, comments, behavioral or physical models, cost elements, as well as verification plans, methods, and procedures if required by the customer's process.
