Cradle® is our requirements management and systems engineering software tool that integrates your entire project lifecycle in one, massively scalable, integrated, multi-user product.

Whether your projects are small and local, large and distributed, or anywhere in between, Cradle can solve all your agile, requirements management, model driven development, defect tracking and test management needs in one place. With its unrivalled feature set, incredible flexibility, simple configuration and low cost, Cradle is the ideal choice if you are new to agile methods, requirements management or systems engineering.

If you are a veteran, moving to Cradle will bring welcome relief from the constraints of other tools and the difficulties of maintaining links between multiple databases. You will finally be free to fully exercise your engineering skills and do what you do best, be creative and inventive. Cradle will become an integral part of your information security and information assurance strategies.

From Concept to Creation

Requirements Capture

Requirement statements can be captured from external documents by Document Loader. It reproduces the document structure in a hierarchy of items. Each item is linked to its origin in the document. Figures are loaded automatically. Tables can be captured into items, images, Word objects or rich text. Document Loader finds differences in new versions of documents. Loading the new version will update items and their links. Coverage analyses between documents and database items are provided. Full version management of source documents is provided. Regression to previous versions is supported, with reversal of all changes. Requirements and other items can be loaded from Word, Excel or other tools using plug-ins, data exchange or direct interfaces.

Requirements Management

Individual locking of each requirement allows direct editing through forms and allows multiple users to concurrently edit. Requirements can be linked to test data, safety and other critical issues, risks or any project data. When used with the Cradle-SYS module, user stories and requirements can be linked to functional, behavioural, UML, analysis, architecture and design models organised into any number of model hierarchies in both analysis and design domains.

Model-Based Systems Engineering (MBSE)

Model-based systems engineering (MBSE) is the formalised application of modelling to support system requirements, design, analysis, verification and validation activities beginning in the conceptual design phase and continuing throughout development and later lifecycle phases. Cradle has over 20 diagram notations that can be used to specify the system. The user selects a diagram type to define system behaviour and a diagram type to define system architecture. The meta-data associated with the models are captured in the project repository for use in analyses and document generation. Learn More

Review your Progress

Items evolve through versions that are managed in baselines and controlled by a build-in CM system, with mechanisms for review, baseline and version control, full change control, and audit trails. Cradle can track all changes. Edits can be reversed selectively or by group. Items can be compared across edits and in baselines. Edits can raise alerts to users, and mark related items as suspect. All edits are permanently available, for change logs. Learn More

Publish Formal Documents

Document Publisher produces complete, high quality, documents directly from the database. It can publish documents that include cover pages, Table of Contents, List of Figures, sections and subsections with mixtures of hierarchical paragraphs, bullet lists, figures and tables. Powerful data filters and parametrics can be defined to supplement database querying or specify conditions under which particular attributes are to appear in the output. Formal documents of baselined information can be produced, with full traceability of which item instances appear in which issues of these documents. All functionality is provided via a simple, intuitive user interface, which is seamlessly integrated with Microsoft Word. Learn More
