Help I’m Melting

melting server
Too Hot!

When it rains we complain, and now that it’s reached more than 28°C here at 3SL ‘towers’, in Cumbria, we’re all searching for ice creams and sharing a few minutes with our servers in their air conditioned room!  However, a week ago, our servers nearly suffered as much as we are now when their air conditioning stopped. Switching to the backup plan of ‘essential only’ machines, we were able to continue working, but it did highlight the importance of planning and designing a robust system. Whilst we may all be able to consider the design requirements/constraints/limitations within our own field, the scope of the environment also needs to be considered. In modelling terms, these are the environment elements:

  • Actors in SysML and UML use case diagrams (UCDs, uc’s)
  • Environment in data flow diagrams (DFDs)
  • Environment in function flow block diagrams (eFFBDs)
  • Environment in process flow diagrams (PFDs)
  • Environment in architecture modelling PADs and AIDs
  • Environment in ADARTS’ software architecture diagrams (SADs)

These symbols represent those parts of the environment with which our system will interact, and provide the means to describe the external interactions that our system has outside it’s own scope In this case the range of the expected external influences exceeded expectations.  It’s worth bearing in mind when designing; whilst you may implement fail-safes, redundancy and extra capacity based internal parameters, it’s sometimes the influences outside our control that have the biggest impact.

Collapsible Panel

If you’ve not tried the following features yet, here are some highlights from the blog.

Forms – Collapsible Panels  – If you have complex amounts of information to deal with on one form, you can roll-up and collapse panels or areas on you Cradle form.

Alerts – Email Templates – If you want additional information, or style customisation, you can now send SMTP client based emails.

Email Alert

For example if when an item is ready for review, if you want the email to say “Please prepare for review of the following item. Which in two weeks time will be the topic of a full Fagan inspection according to company procedure” you can. Alternatively you could add “Hey folks  I hope you’ll all welcome this new user to our project” to the new user alert!

Items – Attribute Sets – A “8mm, Stainless, BSW (British Standard Whitworth)” is different from a “8mm, Stainless, UTS (Unified Thread Standard)” bolt. If you are specifying these components as part of your design solution, you may want to ensure they are unique, there’s no point specifying the same component twice. However, you may want to query on all your 8mm fixings, so having each element as a separate category is really useful. Attribute Sets are a useful tool to ensure that groups of component attributes are unique.

June 2018 Newsletter


June, halfway through the year, its easy to measure and define when we reach that point. Fundamentally that’s because the length of the year is clearly defined and we can measure when we reach the 1/2 way point.

Projects are not that simple.

If we’re unlucky we have no idea where we are or how far through the pile of requirements we have moved.

In a better position we have an idea how many requirements we have and how many have been linked to design solutions and possibly how many of those have been tested. A dashboard can help you quickly visualise these measurements.  The real problem, however, is knowing how much effort you have expended and how much is still needed. Numerically you may have completed 90% of your requirements, with 80% of your budgeted effort. Can the remaining 10% be completed with the remaining 20% budget?

metric showing the LoE expended so far
Effort / Completeness

One method would be to assign an LoE (Level of Effort) to each of the tasks. This then allows a weighted metric to be produced showing the numeric percentage of completed design elements compared to the current weighted effort expended.

This example show that although there are only 13% of the Design elements to complete we expect there is 46% of the total work still to be completed. Better check the budget and required finish date pronto!

Banking Changes

As we have said previously, there have  been some changes in UK banking as some banks have been split so as to  isolate traditional banking from  investment banking activities.  Barclays have confirmed the new SWIFT BIC code is BUKBGB22. Our sort code and account numbers have stayed the same but our IBAN numbers have changed.  This is especially important to our distributors and overseas customers. Please contact salesdetails@threesl.com to request our IBAN numbers. Updates are  posted here.

May 2018 Newsletter

May day, Mayday

Festival of Flora Roman goddess of flowers

We most certainly mean May Day, not Mayday!  But have you ever stopped to think of the origins?

May day can be traced back to the Roman goddess of flowers Floralia, whose day was celebrated at the end of April. As secular celebrations became more popular, and with the calendar of the day, the 1st of May marked the first day of Summer.

From flowers to maypoles and crowning of the May Queen, a celebration of fertility and new life is now more commonly linked to the early holiday in May. (BTW the UK office will be closed on the 7th May 2018 as it is a bank holiday). The celebration is also closely aligned in the USA with Labor Day, a celebration of workers rights to fair and just working practice.

On the other hand the Anglicisation of the French  m’aider, meaning ‘help me’ is used as a verbalisation of S.O.S. We hope a phrase you never have to use. However, if you do feel your project is having a bit of a Mayday moment, maybe you need to ensure its all in Cradle and you have complete control of your requirements…….

Here at 3SL towers we’re celebrating the ‘New Life’ aspect with the birth of Cradle-7.4!

April 2018 Newsletter

Happy New Year!?

Yes, I know it’s the April 2018 Newsletter. The Gregorian calendar was introduced in 1582. The switch by countries was gradual, with the UK changing in 1752. During the switch the UK lost 11 days in September, and the start of the year was moved to January the 1st. We covered some of the strange naming conventions in our October newsletter. Originally the first day of a ‘new year’ was 25th March, this sudden jump would have messed up financial institutions accounts. So they kept the start of the fiscal year more or less where it was, shifting by those same 11 days to 5th April. Or it could have been that the accountants were so drunk at Christmas they just couldn’t face doing the accounts when they returned to work. Take your pick. 

finance image from pexels.com

So if you are lucky enough to be dealing with a new budget for the “new year” now’s the time to check you are getting value for money across all your projects. Are you still dealing with several different tools to manage your Requirements and model your Systems?
Could you consolidate these tools and methods by adding extra licences to your Cradle installation and then  on-boarding (yuck -Sorry read that one in a trendy blog post somewhere) the less enlightened?
On the other hand if you’ve been Spring cleaning and found your project a little out of kilter, you may realise that the management view you have over it,  is not as clear as it ought to be. Then maybe adding a Dash or Metric licence to Cradle could help with getting to grips on the health of your project. However we can help, don’t hesitate to call  us here in the UK or your local distributor.


Measurements and collation of the results are an important management tool.

metrics in Cradle

It is obviously important to manage and track the right thing. Using the ludicrous  quote “The majority of people involved in accidents were wearing white underwear….”, you may jump to the conclusion that brightly coloured pants will keep you safe. Of course this statement is completely meaningless without context because if white pants are the most popular colour you could make that statement apply to any topic.

Provided you are measuring sensible information, percentage of  Requirements that are Accepted, or Underway gives a really useful view about the maturity of your project.

In Cradle you can define any number of metrics, save and re-run them at a later date. A metric is made up of a set of elements, each element is a query to the database to retrieve item(s), and an analysis operation on these items. This could be a simple count, or a more comprehensive coverage analysis of attributes.  Available functions include:

  • Item count
  • Minimum value, Maximum value
  • Averages/spread (mean, median, mode(s), variance (population-based), range, standard deviation (population-based) and semi-interquartile range)
  • Total / Weighted total of values
  • Range of values
  • Pivot table for category values
  • Coverage statistics

The returned values can also be further manipulated with  Metric calculations, combining values with basic mathematical operations. Delve into the help section for more information or read the flyer.

Cradle Features Coming Soon….

As we mentioned in February Cradle 7.4 is on the way. Look out for; New colouring options in (HID) Hierarchy Diagrams,  Additional Regex (regular expression) matches in queries,  Unique attribute checks……..

Heading to Spring

As we head into Spring, most of us are keen to leave behind the horrible weather that came with the Beast from the East. Some of the worst UK snow seen in years. We’re happy to say that Barrow-in-Furness saw

snowy road pexels.com by pixbay.com
Snow Problem

little impact and the support team were able to maintain full levels of service. We hope your businesses were not too badly affected and that you are all heading back to normality.

The question this raises is why are we so bad at coping with a bit of snow here in the UK?

The main problem seems to be that we’re not used to it. It is not a ‘steady state‘ in parts of the world where winter = snow and ice for a set period, the infrastructure is set up to cope. Cars have winter tyres or snow chains,  heated highways or rails keep cars and trains running, or there is value return on investing in ploughs and gritters. The changing requirements of British weather conditions would need you to put the snow chains on and take them off on a daily or even town by town basis. These changing requirements make managing the situation really difficult.  The same logic applies to projects, stable requirements make for a simpler solution. If your requirements are more like British weather, there is even more need to have a formalised approach to managing them. Making sure you can track the changes and your reactions to them becomes imperative.
Don’t end up wearing wellies in the summer and flip-flops in the snow, get you requirements under control in Cradle and encourage your suppliers to do the same.

Cradle Features Coming Soon….

We’re all busy here, in the chilly winds and rain and sleet of Cumbria working on the features for Cradle 7.4 I can reveal that we’ve been working on some enhancements to alerts to allow more comprehensive content to be sent in emails. This will help with collaborative working, swiftly informing interested parties that an item has changed which may need their attention. Item level Workflows are being enhanced to improve automation of your product lifecycle.


padlock over computer based on images from negativespace.co pixabay.com on pexels.com

Time is racing towards the GDPR implementation date. We’re working hard to ensure our policies are up to date and in a fit state to deal with any data requests. However, there’s still a lot of confusion out there. Some things are obvious, were we to store sensitive information, like someone’s medical records, religious or political beliefs, its fairly obvious that this should never be swapped freely. The subject should be aware as to why we hold the data, what we hold and how we use and process it. We would then ensure any third party processors were up to the same standards before exchanging information.

At the other end of the scale, the ‘how would this ever be practical’ bit, there is little in the way of concrete guidance. If I email a company, from my desk at 3SL, my email address contains my name and associates me with 3SL. The sign off contains a phone number and an office location. By the letter of the legislation, this is personally identifiable information. Were I to leave 3SL (To become a top secret agent) and decided all previous traces of me needed to be removed, I could submit a ‘right to be forgotten’ to 3SL. They would have to remove all my personal data. (Except for ‘within date’ tax records etc.). As the data controller, all those emails with personally identifiable information within them would have to be recalled from all the recipients (who are now processors). Now how on earth could you do that?

If you’ve got any examples where the legislation appears to hit an impractical wall, drop us a line and we may feature it in a future blog. Note I’m using an anonymous email address social-GDPR@threesl.com !!

New Year’s Resolution

We all make promises to ourselves, many we find hard to keep. Yet another sucker falls for the gym membership sign up and then decides binge watching that box-set is easier/more enjoyable/cheaper. It does really seem like the worst time of year to be making decisions to be getting out and about exercising. (Apologies, again, to our customers on the other side of the globe – read this again in 6 months !).

Data Exchange Microsoft® Project / Cradle

One resolution that should be easier to keep is to start afresh with plans for current and new projects. We’ve had time to allow our heads to clear over the Christmas break and should be facing work with a new vigour.  Planning is the key to ensuring schedules and expectations are met.  This may seem like a very un-Cradle® plug, what’s planning got to do with modelling and requirements? The answer is in fact quite a lot. Without a project management plan and schedule how would the capture, design, review and test be achieved in the right order? A Work Breakdown Structure can be used to segment activities, and component parts of a project into manageable chunks. The ability to link a plan from Microsoft® Project brings together the planning and implementation elements of your project. For more information see the Cradle Help on Project Capture

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.

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.”

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 pexels.com
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.

“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.”
