As most people are aware, those doing business with any European country will have to abide by some stricter data protection guidelines. There’s a lot of hype and scaremongering going on at the moment as people try to come to grips with the extent of the changes. 3SL are undertaking their data audits to ensure we only hold personal data necessary to run 3SL and to support our Customer’s contracts.
3SL hold very little personally identifiable information on our customers, but even your name/email address/company need to be protected. We don’t sell or trade or provide information we hold with third parties, unless it is either a legal requirement to do so, or necessary to complete a contract such as with our Bank or Credit Card processor. We’ll be publishing our policies either on our website or to be made available on request.
We hope you agree that we don’t send unnecessary communications to you, for example these newsletters are the way we communicate important changes, release information and articles that may assist in your use of Cradle. However, if we decide to classify any communications or interactions as extras, we may ask you to specifically opt in to receive them. We hope you’ll agree to continue to receive them and you will of course have the option to opt out at any time. If you have any questions at present, please send them to .

November 2017 Newsletter

Remember, Remember any date in November….

For many of us the clocks have gone back and we’re entering that period where it is dark when we travel to work and dark when we travel home.
This means the brightest thing we may see all day is the monitor glaring in front of us. Of course we should be mindful of problems sitting in front of a VDU and ensure we take regular breaks, but it does mean you can concentrate on your projects without wanting to  be outside*1 ! However, back to the date theme, not every Cradle user is aware that they can use relative queries on dates. Using these relative values, queries can be set to list all the activity in the last month or last week. So you can indeed “Remember, remember any issues/requirements/tests raised (as opposed to rased) in November.”

screenshot showing how to set relative date in a query
Relative Dates

The query results at the top of the above screenshot, shows all components in a project. The relative modified date query in the lower half shows only those components modified between the beginning of the month and today.

There are a number of relative dates you can use, Start of this week, Start of three months ago, End of last month and so on. You can read more about query dates in the Cradle Help under the “Select the Dates Tab”

October 2017 Newsletter

October – The ‘8th’ month of the year….

Calendar - based on image from
Everything can Change

Octo is 8 after all, from Latin octo, Greek okto. In Romulus’s calendar, when the year started in March, it was the 8th month. However, given they only had 10 months, they also had around 50 days of ‘winter’ that didn’t really have a name. For a time we then ended up with 13 months, but in the final Julian system, only January and February remained inserted at the beginning of the year.  Roman emperors were honoured by renaming a couple of months and we are where we are today.
“OK, what’s the point”, we hear you cry. It’s that nothing is really stable, something currently taken for granted (months of the year) has a long complex history. So do many projects. They start off in one direction with one set of assumptions, constraints and regulations and then……BANG! A change is dropped on your desk which changes the original assumptions, impacts the design, has repercussions for tests and so on.
Taking a baseline when things are relatively stable is a good way to record the status-quo in your project at any one time. Lock down things as they stand so you have a stable footing against which to document and measure change. Check at what point Mercedonius (month of wages) was retired.  Use formal Change Requests and Change Tasks to record why an alteration is needed. (Because Julius said reform, because Augustus needs to be honoured). Use the trace facilities of cross references and suspect integrity highlighting, in Cradle, to see what impact a change in the chain will have.

New Customers

Welcome to all our new customer’s this quarter.  Especially Public Health England who have recently selected Cradle for a major operational plan.

Cradle® has been selected by Public Health England (PHE) to manage the definition and fulfilment of requirements for its Science Hub programme. This £400 million project will design and build a world class national public health science hub and headquarters in Harlow that will bring together personnel from PHE’s Porton, Colindale and central  London sites. The PHE Harlow site is scheduled to be fully operational in 2024.

Cradle is a requirements management, enterprise architecture and systems  engineering tool that integrates the entire lifecycle of development,  organisational and infrastructure projects that use agile or phase-based methods. Cradle is an ideal solution for procurement projects for ITT generation, bid assessment and contract management, by providing  traceability between a managed, configuration-controlled multi-user database and all external source and published documents.

Mark Walker, Director of 3SL said:

“We are delighted that PHE has chosen  Cradle for this important infrastructure and reorganisation programme. We welcome the opportunity for a long-term partnership with PHE and confident that Cradle will make a significant contribution to the successful realisation of the new PHE Harlow site.”

September – Autumn on the way

Autumn leaf

It’s back to school and college for many of our young people. As businesses it should also be a time to reflect what lesson’s we’ve learned so far this year now we’ve arrived at Q3.

Take Stock

  • Which of your projects are on schedule,
  • Which of your projects are on budget,
  • Which of your projects are not really being measured?

These are all questions that a good PM (Project Manager) should be able to answer quickly and succinctly. Unfortunately that’s not always the case. Dates and milestones were not clearly defined so schedule is difficult to measure. What part of the budget applies to what part of the solution is not clear so spend can not be measured accurately. How many Requirements have actually been split into System Requirements or Functional Blocks is not calculable.

Don’t Panic

Cradle’s features can offer assistance with these issues.

  • Cradle offers the ability to link Work Breakdown Structure (WBS) items to Microsoft® Project allowing a direct connection between the Project Plan and packages of work related to designs, functions, tests etc. in the Cradle project
  • If a Budget item is created in Cradle, it could be easily linked to other components of the project. They could then have a category of actual spend. Using Cradle’s calculation facility, these linked items can be totted up and shown in the parent item.

    screenshot of aggregate calculations
    Aggregate Spend with Calculations
  • Dashboards are a quick visual aid showing your Key Performance Indicators (KPI) showing percentage of Requirements with System Requirements attached is a good way of monitoring progress.

Control and Relax

Move into Q4 with all the project knowledge you need to finish the year on a high.

Banking Changes

There are some changes afoot for those that deal with 3SL financially.

In response to the 2008 financial crisis, the UK Government has decided that all major banks must protect their personal, retail and most business banking operations from their more risky, often speculative, investment banking and international banking operations.

Most major banks in the UK will do this by  creating a new ‘ring fenced‘ banking operation that is protected from future problems in the financial markets.

Most of the UK’s major banks will effect this change in April 2018.

For 3SL, these banking changes will mean that there will be a new BIC (bank identifier code) within the IBAN (international bank account number) of all of our bank accounts. In  effect, all of the IBANs for our bank accounts will change in April 2018.

It is also possible that banking changes may effect another part of our bank account numbers, called the sort code (similar to the ATA, routing number or  branch number codes in other countries’ banking systems). If there is a  change to our sort code, the change is likely to occur in January 2018.

If you are an international supplier to 3SL, or one of our international customers, then it is possible that our IBANs will change in January 2018, and they will definitely change in April 2018 when the new ‘ring fenced’ bank in Barclays PLC receives its new BIC.

All of these changes are being completed in advance of the UK Government’s deadline of January 2019.

We believe that our current IBANs will remain available for 36 months after the change in April 2018.

We will provide more information as it becomes available. In the mean time, we apologise for the inconvenience that these changes will cause to our UK and international customers and suppliers.

Last month saw the start of the Summer and also National Sunglasses day. We still hear the odd story that engineers are using ‘Spreadsheets‘ and ‘Word-processor documents‘ to manage their requirements. We can only sympathise with their misguided ways and revel in the fact that we (and you our dear newsletter readers) have seen the light.

This month (July 2017 Newsletter) we’re highlighting c_io and how it can be used to complement the functionality we’re more used to in WorkBench and Web Access.


Using c_io.exe in a batch file means you can do many things whilst you are away from your desk or in the background while you continue to work. You can then add this batch file to be run by a task application during times you are away from your desk or work. This can be handy when needing to do backups of a single or many large databases.

The executable can import and export everything in a project from single items to the whole project. It can use queries or different options to whittle down the required export. So a user can export all items of a specific type or just one to several items based on a query and or other set options.

June 2017 Newsletter

Summer Arrives in June

Looking out of the windows here in Cumbria, summer has well and truly arrived. However, 21st June marks the summer solstice.

It also marks the start of the holiday season. This can be both a trying time for projects and a quieter time in the office. With fewer people and distractions over the coming months, now could be your ideal time to set up trial Cradle projects. Take some time to run a few operations in parallel. Compare how pushing a requirement/design/test through Cradle compares with the manual or tool based version you use now. Even seasoned Cradle users will find there is some project or operation not yet in Cradle, yet ripe to be imported. It could be your ongoing Process Improvement Plan. Whether formally following CMMI or just ensuring you raise, resolve and measure issues in your company’s working processes, then controlling, recording and measuring formally in Cradle makes it easier to manage.  Use a summer vacation student or intern to set up a schema and enter data as a pilot project.

May 2017 Newsletter

May Already

Since our last newsletter: We sincerely hope that those of you who celebrate Easter had a nice break and are not too full of Easter Eggs!   We’ve also had an Activity Diagram to celebrate St. George’s day and tried to conquer the Universe on Star Wars Day with some Functional Modelling. That aside development continues on Cradle 7.3.

New Voices

We’ve expanded the writing team to include authors from elsewhere in the 3SL team. Because this is a blog, there is more emphasis on people’s personal insights into the Cradle product. This should make the style and tone more varied and hopefully more interesting to read.

As you may have already seen the 3SL-Blog is groaning full of new articles. These are mainly “Hints and Tips” and longer RM/SE articles. Increasingly we’ve found that some of the support questions that arrive here in 3SL towers are very similar. To that end we’re publishing them under the FAQ section.

If you have a burning question and would like to see an article covering a particular topic, drop us a line at and we’ll see what we can do. On the other hand, if you have a novel use of Cradle that you’re happy to share with us, drop us a line with the article, screen shots and accreditation details and we may feature it.

Non Graphic Interfaces

There is widespread understanding of the WorkBench and even Web Access interaction with Cradle. It is, after all the main way we interact with the data. However, there are many occasions when we want some of the data from Cradle but don’t want to or can’t use a screen to interact. This month we’re highlighting c_table.


This command line utility can be used to produce Reports, Matrices, Metrics, Graphs or Queries in a tabular form. This can be an HTML, RTF, CSV or SVG output. If every morning you need to go into a meeting, or stand at your ‘toolbox talk’ with a printed report detailing the number of ‘Issues’ with a category of ‘Raised’ you can do this by running one command. Creating a desktop short cut to run the command / batch file you need not start WorkBench just to run the query and publish the result. Even more cunningly a script could be triggered at 8:00am every morning to create the document for you.  Our blog article “Batch File Reporting in Cradle” adds more detail.


If you are working or bidding on large infrastructure projects,  Cradle is now available through the CompeteFor procurement portal. Whatever the size of your Requirements Management or Systems Engineering task, Cradle is there from Concept to Creation.

April 2017 Newsletter

Spring is Here

Since our last update spring has sprung. Once you have got used to losing that valuable extra hour sleep, as day light saving kicked in, it’s traditionally time to think out with the old and in with the new.

Consider a spring clean, remove all those stacks of dusty files full of project requirements version 1 to version 9.

Why Are You Keeping Them?

Will you really be able to find what you are looking for without a way of searching? Consider whether you can sensibly access the details of those designs sitting rolled up in mailing tubes. Do you have the means to edit them electronically any more. Does anyone know where the file is kept?

A New Way Forward

Convert projects you want to keep by inputting them into Cradle. Either by loading the documents through Document Loader or scanning old paper copies. Once scanned they could be stored as an image in an appropriate item type, or stored as a file reference within the Cradle item or an external URL within a form.  Now you have a way of searching through your project data, following the links between items and possibly retiring items / standards / tests that are not longer applicable.

Create A Published Copy

For those poor souls with no copy of Cradle that they may need access to, you can publish a copy to your Intranet, or print a full report through Document Publisher (Just don’t be tempted to print it out hard copy as that’ll defeat the object of the spring clean!).

PS: We’re quite happy for those of you in the Southern hemisphere to have an Autumn Tidy instead !

YouTube Learning

Thanks for those who responded last month to requests for new ‘How Tos’ for our Subscribe to our YouTube channel YouTube channel.  If you didn’t get a chance to reply, here’s the link again ’How To’ ideas.

“Faster and Better Performance”

No, it’s not an advert for a new sports car or for the latest 2017 regulation changes that may ‘increase performance’ in F1 races. You can even put your screwdriver and spanners away. These tweaks to Cradle will help ensure it is in tip top condition and you won’t need an oily rag to do them.

1. Check the time between clients and the server. In the ‘Help’ tab, select ‘About WorkBench’ and ‘Resources’. Look for the ‘average roundtrip time’ line. If the CDS is in your local network, it should be <2 msec. If you connect over a VPN, it should be <25 msec. If longer, you may have a network problem.

2. Consider turning off the user preference ‘Refresh items when modifying links’. In the ‘Home’ tab, click ‘Preferences’, then ‘UI Control’.

3. Consider turning off ‘indicate linked items in trees’ in the same group of preferences.

4. Consider enabling caching of top-level items in Project sidebar, reduces time to find top-level items, in UI Control -> Sidebar preferences.

5. Note that when links are created, modified or deleted, the change histories are updated for items at both ends of the link.

6. Changes to links to/from items could raise alerts to be sent as and possibly sent to large numbers of users.

7. Run the cross reference and item integrity checks in the ‘Project’ tab to find and fix any problems. Issues can arise from ‘unvalidated’ imports of data or links.

8. Ensure that message compression and server-side processing are both active. Look in ‘CDS Settings’ in the preferences for any user. Checkboxes may be greyed out (can only be set on the server), but its set/not set value is accurate.

9. Large numbers of unread alerts will slow Cradle down at login and logout. Check options in the ‘Alerts’ section of the schema, from ‘Project Setup’ in the ‘Project’ tab. Use ‘Delete alerts’ in this tab to remove current user’s alerts.

10. Read the performance section in the System Administration manual

New Release – Cradle 7.2

We are pleased to announce the release of Cradle-7.2:

Cradle-7.2 interface

Cradle-7.2 contains a range of new capabilities that are described in its Release Notes.

Customers with active maintenance have been sent an e-mail notification of this release, and details of which enhancement requests and bug reports are in it.

Some of the highlights are:

Download and Installation

Login and download Cradle-7.2 from our website here:

You need a new Security Code for Cradle-7.2, other Security Codes cannot be used. If you have not received a new code and are under maintenance, please contact If you would like to discuss upgrading an out of date system, please contact If you have a single user version you can purchase the latest revision at the 3SL shop.

There is a database conversion from 7.1 to 7.2. The converter which will run automatically if you install Cradle-7.2, over the top of, in the same directory as, the earlier version of Cradle from which you are upgrading.

You must upgrade all of your Cradle installation to 7.2. (clients and server) as mixed versions, e.g. Cradle-7.1 clients / Cradle-7.2 server, and vice-versa are not supported.

I have a Cunning Plan…..

OK it does not have to be cunning, it just has to be clear. Cradle provides a bi-directional integration with Microsoft Project® that allows a Cradle project to be associated with multiple Project schedules and bidirectional updates with Project. By linking activities in each schedule to become a WBS hierarchy in Cradle the loop is closed and the plan and the Cradle requirements and models are all linked.

The main reasons to control things this way is to ensure there is no inconsistency between the management planning and the project engineering. To ensure that each engineering activity is planned for and each element of the plan has some actual work assigned to it, avoiding incompleteness. A plan linked to Cradle communicates the holistic view of progress and items all in one place.

To read more on this topic, our whitepaper “Integrated Project Management from Cradle” can be read here.

Remembering the old adage “Tell me and I forget, Show me and I remember, Involve me and I understand” seems very appropriate. But what aspects are most appropriate to you our customer?

In this article 3SL’s managing director Mark Walker, asks for your feedback to guide 3SL’s video output.

“But the customer has sent it as an mp4!”

  • Your boss wants you to record the evidence of the test to provide full traceability
  • The testing house has sent a video of the compression strength test
  • You’re ‘stuck’ with all your requirements and tests in Cradle and now you have a video…

Don’t worry it’s not a problem. Although Cradle may not be able to play videos, it can store all sorts of information in its database, or by reference to external files. We provide a large list of files pre-defined, but Cradle can easily cope with new file types.

In this case you would add a binary frame to store video, you may have a directory alongside the Cradle database where these files reside, so an ‘As File’ frame would make sense, or if it is also to be controlled through the Cradle CMS (Configuration Management System) it could be “In PDB” (Project Database). You would choose our favourite app to view them in, then you would assign a frame of this type to your, say, TEST item type. Now you have the traceability you need with the test evidence referenced from the TEST item and links to the SYSTEM_REQUIREMENT through to the original customer Requirement.

In our LinkedIn discussion we describe adding a Document to an item.
