Product Details

Cradle-7.1 integrates requirements management and systems engineering with full MBSE (including SysML, UML, BPM) for collaboration in agile and phase-based projects.
3SL’s Cradle is a tool to load, create, inter-link and publish information for all stages in a systems engineering project using agile, iterative or phase-based approaches and using any process. It is completely user-definable, scalable, flexible and secure. It can be deployed locally in your organisation or project, deployed to remote sites or partners, or delivered through SaaS from any private or public cloud. Cradle can support all your requirements management and systems engineering work in one tool, including:

  • Load information from external sources
  • Manage needs, user stories, requirements and a product backlog
  • Analyse the user needs, optionally with models (MBSE)
  • Define the design constraints
  • Define the architecture, optionally with models
  • Create the design, optionally with models
  • Define and track tests, issues and defects at all levels
  • Manage user acceptance and system validation
  • Conduct traceability and coverage analyses across all information in the entire lifecycle or any part of it
  • Publish documentation with user-defined layouts and templates
  • Manage work breakdown structures and user task lists, record actual progress, and link bi-directionally to project planning tools
  • Reuse and share information between projects

Cradle is available as a range of single-user products and the multi-user Enterprise product that adds configuration management, unlimited scalability and floating and dynamic concurrent user licensing. All Cradle products can be customised to your project and to your process. Cradle Enterprise provides additional customisation facilities to replace large parts of the Cradle UI with your own start pages and phase hierarchy that optimise Cradle to your process and your way of working. You can define web UIs for each stakeholder group that present the information needed by each group with the features and controls needed by that group to do their work.

Features

  • Full lifecycle systems engineering environment
  • Completely userdefined database with unlimited item types, items, attributes, data, link types, and cross reference links
  • Manages information source documents, through needs and requirements into architecture and functionality/behaviour to testing, V&V and acceptance
  • Massively scalable for small to large, distributed teams
  • Full traceability from source documents, through any engineering process into all published documentation
  • Usable across all industry sectors and government agencies
  • Can manage contractual relationships in entire supply chain

Shoulds and Shalls

Conformance Checker

Do you need to validate the quality of your Requirements?  Using Cradle’s Conformance Checker will help you sort the to sort the “shoulds” from the “shalls”. Validate your items’ text  with a set of regular expressions to ensure you have clear statements.

Picture of conformance checker output
Conformance check your “Shoulds” and “Shalls”

Language Analysis

There are numerous aspects you can search for in the Cradle Conformance Checker.

  1. Stipulations such as Shall and Must
  2. Expectations such as Should
  3. Desires such as Might
  4. Continuations such as  As Follows
  5. Exemplifications such as e.g.
  6. Detractions such as Around
  7. Incompletes such as TBD

These can all be altered to suit your language and product / engineering domain. They are written as Regular Expressions (Regexes) through the project setup.

All Linked or Cross Referenced Items?

What’s the difference between “All linked items” and “All cross referenced items”

If you’ve ever wondered what the difference is between these link types in a view in Cradle, this should clarify:

  • Cross references are actual links that have their own properties and can be tailored by the user. They have rules to control their creation, modification and deletion.
  • Links include Cross References, but also include pseudo associative links. An example would be a Specification that is associated with a Diagram by its identity.

Regulation, Compliance and Traceability from Cradle

Discovery, Implementation, Demonstration, is this really what making a product is all about?

From a product development point of view, Elicitation, Analysis, Specification and Validation may be terms an engineer is more familiar with. However, we work in a world where regulation and compliance are hugely important factors in a product’s lifecycle.

As developers and producers we must discover the sets of codes, regulations and standards that form the non functional requirements of our product. We must the implement the changes to our product design to ensure the end product is compliant. Before delivery we must be able to trace our designs and decisions to demonstrate how we comply.

For further discussion on the parallel paths that a product lifecyle must comply, please read one of the 3SL’s whitepapers here.

Twitter Tips

Thanks to those extra follows from January, don’t forget to retweet whenever you find a tip helpful and keep using those #3SL and #Cradle tags.

Baseline Past and Present

Whenever a project reaches a defining moment it is advisable for the project to be baselined. A line in the sand to say ‘we are at this point’, a point from which further development and changes can stem.

However, sometimes we want to return to and extract a particular baseline, say to use as the starting point for a new project variant. See how to export this information in our linked in article

False Positives

Any software developers out there? We’re gathering experiences, encountered while developing and distributing software, of the eternal battle between virus protection, legitimate development and malware hackers. Please join the discussion here on LinkedIn or see it in the ‘Cradle – RM/SE Tool from 3SL’ group.

Many Roles

Do you sit as a person with many hats? Today you are Engineer, tomorrow you are QA Manager? In smaller organisations many people find they wear a number of hats, but like to keep their operations separate. Whether this is from an administration and traceability point of view, or just to prevent a change being made to data accidentally by a role with an elevated privilege (think sudo in Linux). It may also be the case that you want all these roles to exist in the future, but while the embryonic project is being set up and developed there is only a small team working on it. These roles are later handed over to new colleagues.

Cradle allows you to set up all the users individually and then provide a common alias or in Cradle terms a ‘Switch Identity’. The user can then switch between the various roles without the more time consuming logout – remember different password – login loop.

This is further illustrated in our LinkedIn discussion.

MBSE Buzz!

False Positives from Symantec

False positives were recently reported by the Symantec and Trend Micro Office Scan Anti-Virus (AV) products. In both cases, they falsely reported a problem with the c_image.exe executable (which simply displays images, such as the Cradle splash screen).

We have arrangements with these and other AV vendors to pre-qualify Cradle executables before release. We do not know why these products have started to produce false positives for c_image.exe, since this executable has not changed and has previously been included in these products’ whitelists.

We have reported this problem to both vendors and can confirm that c_image.exe is in the whitelists of these products as of 11.1.17.

We apologise for any inconvenience caused.

From Now to Goal – Requirements Management

Goal

If you don’t know where you are currently, or how you arrived or what your ultimate goal is, how do you know in which direction to head? Requirements Management is a skill made easier by the full traceability of tools such as Cradle.

From – Now – Goal

Build Me a Home

Starting a project without having a base understanding of the situation is a like building a house on unstable foundations. When the walls start to wander you’ll have no idea whether it was because the foundations were not level or were inappropriate or whether the direction of the wall is simply wrong.

Not knowing the ultimate goal could lead to a double height wall being built for a bungalow.

If you have no measure of how high the wall currently stands, you’ll have no chance of estimating how long it will take to finish.

Baseline, Elicit  and Measure

It may sound obvious when applied to the ‘simple’ task of  building a home. It appears ridiculous to start building without knowing whether our goal is a bungalow, house or flat. Yet many projects start with a very loose understanding  between stakeholders and producers and can head off in the wrong direction.

Baseline

Do we know the current situation? Do the foundations exist, is this a single storey  build that needs extending with an upper floor or are we to start from scratch. Are there any assumptions we need to record, this project assumes that there bedrock will be found within a metre.

Elicit Requirements

Have we investigated what the customer / stakeholder actually wants? We could achieve the same m2 with two storeys or one larger floor. No point building a house and then finding mobility restrictions mean a bungalow was needed. Do they actually need a house. The baseline may show they actually have somewhere to live and all they need is some more storage. We could provide them with a shed and achieve their goal. This honesty in not selling them a new house may mean we have a smaller turnover, but a far better reputation. This should lead to repeat and new business as knowledgeable supplier.

Measure

This needs to be done at each stage. Internally we need to know that we are meeting the design. When do we stop building the walls? Externally we need to know that the customer is going to be happy. Milestones and intermediate reviews will prevent big surprises at the end. Whilst we want to avoid requirements creep, we have no intention to build a mansion for the price of a flat, customer requirements change and to remain agile, we need to build in steps to accommodate change.

Summary

If you can see the sense in this simplistic example you have every justification you need to correctly control and manage your project. If you can’t see the point, you’re likely to return to your back of envelope calculations and assumptions of what your customer needs. Good luck to you, but we’d prefer you to take steps to de-risk your plans. Put yourself on the receiving end, a 20 storey building each with a floor of 1m*1m and a ladder pinned to the outside. It fulfils the requirements, but you try sleeping in your new bedsit.

Making Space – Maximized Data Display Area

I Need More Space

There is a lot of information in the WorkBench UI (User Interface). Sometimes you want a concentrate on one aspect, and it many not be possible to see everything you want in one go. You may be using Cradle on a laptop or tablet with a small screen and a limited display resolution. If so, you may want a maximised data display area, by reducing the screen area occupied by the Cradle UI controls. Make space in Cradle’s WorkBench interface by closing sidebars and the ribbon, status bar and Quick Access Bar (QAB).

Maximised Data Display Area

You can do several things to maximise what you can see in the WorkBench UI. In general, these are all to minimise or hide parts of the WorkBench UI. You can make many of these changes permanent by setting your preferences. To set yourpreferences, select Preferences in the Home tab, make the changes (typically in the UI Control group) and finally, click OK.

Hide the Sidebar

You can hide the sidebar on the left of the UI by clicking whichever sidebar’s button is currently selected. This will make the sidebar disappear.

You can prevent a sidebar being shown when WorkBench starts by setting the Default sidebar user preference to None:

Set No Sidebar

Hide the Quick Access Bar

The Quick Access Bar is a horizontal menu of buttons that provides easy access to sets of queries that Cradle creates automatically when you define item types in your database schema.

You can hide the quick access bar from the Window group in the ribbon:

Set No Quick Access Bar

Hide the Status Bar

The Status Bar is a horizontal collection of status indicators shown across the bottom of the UI. You can hide the status bar from the Window group in the ribbon:

Hide the Status Bar

Minimise the Ribbon

You can minimise the ribbon across the top of the UI by double-clicking to the right of the tabs, typically to the right of the Help tab.

Maximise Diagram Area

When you edit or view a diagram in any model, Cradle will display it in a form. This form includes the diagram’s symbols in a drawing area. It also includes other diagram attributes. You can set the preference so that you only see the diagram’s symbols when a diagram is first drawn:

Hide Diagram Attributes

Press A to toggle the display of the other diagram attributes.

Normal Display Area

For illustration, a typical WorkBench UI showing a query with a simple view in Table style would appear like this:

Manual ‘ V’ Cradle

Compare

When it comes to managing your requirements  and designs there really is no contest between a manual based system and a tool based system.  A cross referenced and baselined design in Cradle is your ultimate goal.

Manual

A manual based system at worst is a set of paper requirements, managed in folders with paper-clips and sticky notes. An electronic system may include a number of word processor documents, drawings and spreadsheets. These have very limited, or manually updated meta data to describe how they interlink.

RM tool

A Requirements Management and Systems Engineering software tool brings these elements together in one place and provides the meta data and traceability that binds them together into a successful project.
