Cradle Modules – PDM

The Cradle PDM module provides the infrastructure for all other Cradle modules. Its scalability and flexibility create an industrial strength, proven, shared data environment for even the largest projects:

Databases

Cradle supports any number of databases, each with its own schema, CM system and users. Each database supports many projects. Use the Project Manager tool to organise this environment by user-defined criteria, for example as hierarchies.

Each database stores any number of items, of any number of types (requirements, risks, classes, user stories, functions) defined by a UI. Items have any number of attributes, each of a user-defined type, that manage up to 1 TByte of any type of data, held in Cradle, or referenced in external files, URLs or another tool or environment.

Calculations

User-defined calculations are supported in all parts of Cradle and can be displayed as graphs, in views and user-defined reports. User-defined rules can be applied to automatically set attribute values or perform calculations, to maintain the integrity within and between items.

Cross References

Items can be cross referenced, with optional user-defined link types and groups. Links have user-defined attributes to justify, parametrise, explain or characterise them. You control which links are used to navigate or report traceability, based on link type or group, direction and link attribute values. Links are both direct and indirect, for full lifecycle traceability, impact and coverage analyses.

Process Tailored Environment

You use start pages and a phase hierarchy to build an environment tailored to your process. End users only need to be trained in your interface, reducing training time and costs:

  • Start pages are text and graphics controls that perform your choice of operations simply and easily
  • The phase hierarchy shows the process as a hierarchy in which an agile or phase activity, task, sprint, report or document is run by a mouse click. Different parts of the phase hierarchy can be shown to each user or stakeholder group.

Traceability and coverage views are available as trees, nested and pivot tables, matrices and Hierarchy Diagrams. Unique transitive links give traceability across the full system lifecycle.

Configuration Management

Items evolve through versions that are managed in baselines and controlled by a built-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.

Adaptations

Cradle provides adaptations to allow variants of items. This mechanism is ideal for databases that contain a library of standard items and projects that use the library, and contribute to it.

Access Controls

Access controls apply to all items based on user roles, privileges, security clearances and skills. Users can be grouped in a hierarchy of teams, to create any access control scheme, such as for customers, subcontractors and IV&V. The creation and manipulation of links can be controlled, by item or user.

Cradle is multi-user. It locks information at item level, with automatic database commit after an edit. This maximises users’ interaction with the database and guarantees all data s up-to-date.

Alerts

Cradle’s alert mechanism sends messages by email (SMTP or IMAP), Cradle or both. Alerts can be selectively enabled and disabled. Alerts track events on items, including edit, review and formal change.

Discussions

The Cradle discussion mechanism allows even read-only users to add comments to items. Four other commenting mechanisms are provided.

Project Planning

Cradle can manage project plans and WBS. User task lists are maintained. WBS structures and progress data can be exchanged bidirectionally with external PM tools. Cradle can generate burn-down and earned-value graphs on any user-defined criterion to monitor progress.

API

Cradle is open and extensible. It provides multiple import/export formats, an API, a user-definable event-driven command interface, interfaces with other tools and bidirectional interfaces to Microsoft Office.

Query and Report Data

Cradle provides uniquely powerful data query and visualisation facilities. Each user’s environment can be tailored by defining custom queries, views, forms, navigations, matrices, reports and other facilities. All customisations have a scope, to be specific to the end user, or shared with other users of the same type (such as all customers or all managers), the user’s team, the entire project, or all projects.

Any desired compliance, coverage or traceability report can be created quickly/easily using Cradle’s queries, multi-row views/nested table view, and saved for later use.

Licensing

Cradle has floating, dynamic licensing and low cost read-only users. Open and named user licences are available. Everything described here is free of charge.

Licences, databases and schemas are interchangeable across Linux and Windows 8.1, 10, 11, Server 2012 R2, 2016 and 2019.

Optional support for Oracle and MySQL.

  • User-definable views of data including tables, trees, documents, matrices, diagrams and graphs
  • User-defined metrics and management dashboards

Cradle Enterprise is a complete multi-user solution to manage, trace and document all the data for your agile and phase-based projects.

Capture and Track Information

Capture information from external documents and tools, and track changes in these sources. You can build new sets of requirements, analysis, architecture and design models, tests or verifications, and link them to the source data and to each other. Check the consistency and quality of this information, and prove the integrity of the models and other data with bi-directional coverage and traceability analyses.

Customers’ confidence can be raised with proof that your work satisfies its sources and constraints, and will meet their needs.

Easily track progress with metrics and KPIs and link to your WBS and actual progress to your project planning tools.

Create Databases and Information

Create any number of databases, each with a schema and multiple projects that contain any number of items of any number of user-defined item types. Each item has any number of attributes with up to 1TByte of data, held in Cradle, or referenced in files, URLs or other tools.

All items can be linked with user-defined types of cross reference. The links have attributes to justify, explain or parametise them. Links are direct and indirect, for full lifecycle traceability, impact and coverage analyses.

External documents can be loaded into hierarchies of items. Every item in Cradle is linked to its source in a document. Changes in new document versions are automatically found and the database updated. You can prove the integrity of all source data to your customers with a range of detailed coverage analyses of their documents.

Items can be linear, hierarchical and in many-to-many relationships. Items can be split, merged and reordered. All information can be shared and reused. Cradle can support product ranges, models, variants and builds, and generate comparative analyses between them as tables, pivot tables and matrices.

Create any number of analysis, logical, process, architecture or design models in SysML, UML, SASD, IDEF, ADARTS and other notations. Optionally group models in hierarchies and link elements of all models to requirements, SBS, issues, test cases and all other information.

Track and View Information

Cradle tracks all edits to every requirement, test case, verification and all other information that you want it to hold. Edits can be reversed selectively or by group. Full or partial change logs are readily available.

Control the work with team hierarchies, roles and access controls. Review items with discussions, user-defined workflows and built-in CM with baselines, full version control and formal change management.

You define how information is viewed and reported in any number of views, shown as nested tables, trees, matrices, pivot tables and as diagrams.

Generate versions of documents such as a URD, SRD, IRS, SDS and SSDS to match your or your client’s formats with user-defined templates and detailed traceability of which items were published in each document issue.

Manage Projects

Manage your projects with:

  • Metrics, user-defined calculations of items’ values
  • Key Performance Indicators (KPIs), results of metric calculations with colour-coded display bands
  • Bi-directional links to Project, including user task lists and actual progress reporting

Cradle is open. It supports many import/export formats, has several interface mechanisms to link to other tools, and connects to Microsoft Office components Word, Excel, PowerPoint, Visio and Project.

Cradle is simple to customise and use through point-and-click UIs.

Hiding Unused Item Types

Each Cradle project contains item types that can be linked together by cross references:

  • You define the types of items, their characteristics and their attributes
  • You define the types of cross references and their attributes, and the rules by which they link items

There are several item types that are included by default in Cradle, such as:

  • Source documents – captured using Document Loader
  • Formal documents– formal saved Document Publisher output
  • Requirements – standard requirement type that you might wish to replace with a system note type instead
  • Events – used in the analysis stage of a project to model the environment of a system and to describe how the system interacts with this environment
  • Essential Domain – analysis models
  • Implementation Domain – design models
  • Project plans – integration with Microsoft Project
    Items shown in interface
    Before hiding unused item types

    Some of the item types might not be necessary in your schema so you can remove unused item types/information in the Miscellaneous section of Project Setup:

    Hide option in Project Setup
    Setting item types to be hidden

Once applied and WorkBench restarted, you will no longer see the item types/information you have chosen to hide. This includes:

  • Project sidebar nodes
  • Sidebars
  • Menus
  • Item type chooser
  • Query, View and Form Details dialogs

    Items hidden from user interface
    After hiding unused item types

This also applies to the Web Access default and basic user interfaces.

Filtering Cross References in a Query

Filtering cross references in a query is easy within Cradle.

Showing Cross References in a Query within Cradle

In this example we will create a query that shows links between all system requirements linked to all verifications.

  1. Create a query that shows all system requirements
  2. Then create a nested view which shows links to verification items
View Details dialog filtering cross references
View Details Dialog

This will display as shown below:

Query showing linked items
Query showing linked items

In this example 97 items are returned.

Show only Items that have a Linked Item

To only show items that are linked to one or more verification item, edit the Query Details dialog:

Query Details filtering cross references
Query Details dialog showing Links

which displays as follows:

Query showing linked items
Query showing only items that are linked

As you can see the list of items has now reduced to 43.

Show Items where Linked Item has a Category set

To only show items where the verification has a PASS value set in a category, a query is created.

  1. Create a query that only shows verifications that have a Pass value set:
Query Details showing category set
Query Details dialog showing Category set to Pass
Query showing passed items
Query showing passed items

Refer to this query in the Links tab of the Query Details dialog. Note that instead of using To Items set to Of Type, we have chosen Matching Query:

Query Details filtering cross references
Query Details showing Matching Query

You can now see the list has reduced to 28 items. These being the system requirements that have a Pass for one or more of the linked verifications.

Query showing passed linked items
Query showing passed linked items

September 2022 Newsletter

Welcome to the latest newsletter from 3SL that provides a mixture of news and technical information about us, and our requirements management and systems engineering tool “Cradle”. We would especially like to welcome everyone who has purchased Cradle in the past month and those who are currently evaluating Cradle for their projects and processes.

We hope that we, and Cradle, can deliver real and measurable benefits to all of the exciting development projects that we see every day through your regular contacts with our support team. If you have any problems, please do not hesitate to contact 3SL support here.

Showing Cell Titles in Views

Sometimes when displaying a nested view the cell titles take up a lot of space on the screen.

Displaying Cell Titles
Displaying Cell Titles

Within the View Details dialog you have the option to choose whether you want to display the cell titles:

Show cell titles option
Displaying cell titles in views

As you can see you can choose to either:

  • Show the cell titles
  • Hide the cell titles
  • Show the cell titles only when the view is top-level

You can change the visibility of any of the component views that are being used to show linked items. In practice, most people either hide everything or show everything.

For further information on views please see our online help page.

Showing Filtered “Transitive” Links in Tables

Problem

We have created some links between Cradle items but we only want to see a filtered set of these links in our table.

Rationale

Cradle has a unique ability to follow cross references transitively. This means that although an item might not be directly cross referenced from it’s source, it might be linked indirectly through another item/item type.

Cradle also has the ability to name cross references referred to as link types and even group sets of link types together referred to as link groups.

Combining these features can allow flexibility for the output of items that have some relationship to the source which will reduce the number of direct cross references required.

For example, we would like to show dependencies between item type A and item type C but ONLY those that have a yellow and blue link type.

We can see in the screenshot below that only A-6 and A-11 are transitively linked to items of item type C with both a blue and a yellow link:

Setting Link Groups

We can define a link group in Project Setup in which we can select from the available link types.

This defined link group can be used in navigations.

Defining Navigations

Navigations allow us to specify how we would like to follow the links that have been created between items. This is a very powerful feature as we can also specify that we would like to follow links transitively:

Defining a Navigation to follow Cross References transitively in the Navigation Details Window
Defining Navigations to Follow Cross References Transitively

Using the Navigation in Views

We can now use the navigation to specify that we want to show links between item type A and item type C that are followed transitively but we ONLY want to show the group of links YELLOW AND BLUE. Remember that there are NO DIRECT links between these two item types. The cross references are from item type A to item type B and also from item type B to item type C:

Using the Transitive Navigation in Views

Applying this view, we can see that only the YELLOW AND BLUE links are shown in the table. The remainder appear blank:

Using the Navigation in Queries

We might wish to only show items in our table that have these links in preference to showing all items and just appearing blank where the transitive link does not exist. We can achieve this in the Query Details dialog:

Using the Query Details Window to filter items that do not have any indirect transitive links
Filtering Items Non-Linked Items in a Query

This will now filter out of the list any items that do not match the navigation criteria:

Showing Path in a Tree Style

If we followed the path in a tree style showing downward links, we can see that item type A (A-6 and A-11) are not directly linked to item type C (C-1). They go through item type B (B-2):

Summary

Cradle provides a unique ability to allow cross references to be followed transitively (through other items).

Transitive navigations can be applied to views and queries. This provides a very powerful filtering mechanism that allows us to show non-direct dependencies between items.
