0.001, 0.01, 0.1, 1, 10, 100, 1000

Monetary sub divisions, we are these days, quite familiar with. However, mathematically simple and consistent measurements certainly have not always been the case. The units and ratios we have used in the past had their benefits, and also their complications.

Lsd ( ell-ess-DEE)

This was the popular name for the once common pre-decimal currencies throughout Europe. Spread by the Romans, it was the king of the Franks that standardised the non-decimal ratios between them. Librae, solidi and denarii were introduced into Britain in the late 8th century by King Offa. The British coins became £sd or pounds, shillings and pence.  Money like many of the other measurements, such as length, mass and volume had evolved from various systems used locally and built upon when exchange or trade became necessary.

Europe switched to decimal relationships in the 18th and 19th centuries. The UK held out until the 20th before swapping. Fifty years ago on February the 15th the UK switched to the decimal system. There was now a simple decimal relationship between the pound and it’s sub divided part the penny, of  1:100, rather than 240. Out went Shillings, Thropences, Florins and Crowns.  However, whist all major transactions and banking rounded to the penny, for small value items there was a need for another sub division. It was decided 0.1p was too small to be of use in the conversion between old and new so the ½p or half penny at 200th’s of a £ was part of the mix. It remained so until 1984!

Switching

The switch took around 18 months to complete. Shop keepers often showed dual prices using the agreed conversion tables, to make it easier for shoppers to make the switch. This swap was remarkably quick compared to the change to the metric system. Hundreds of different measures were localised, and it took the French revolution to kick-start the change to decimally divided measurements based on natural physical constants. From 1799 it was around 50 years before various decrees and the spreading of standards really took hold. Seeing no reason to change, the UK other than those in the scientific communities who needed to share data remained with the non-decimal  non-metric measures until the mid 20th century. 

Units

There is an importance to uniform measure and units to make sure everyone uses the definition. In Cradle labelling the column of the View or the element in the Form can make it more clear to the reader what the value represents. A description can be added to the category itself which will be displayed as a tool-tip. Additionally you may want an additional category with a set of units that the user can choose from. This will also make for easy querying and sorting (for example search for all components specified in feet)

Cradle Release

At the beginning of February we released Cradle 7.6. Details of the new features (Risk Management and Test Execution and Recording) and updates to existing functionality can be found in our Release announcement. Keep an eye on the upcoming blog articles detailing their use. Full details of all the changes are included in the release notes included with the download.

For those with maintenance, if you have not downloaded the software and requested a new security code, contact 3SL support so you can upgrade for free.

If you have a single user version, because this is a minor version release (as opposed to a patch) you will need to buy the latest version to take advantage of some of the feature updates.
Please note that some features, such as the new Test and Risk module, are not available in the single user versions and you must check their suitability on our products comparison page.

Training Courses

Don’t forget to check and book onto the Cradle Public training courses.  The full calendar, and any updates, are available here. If you want a consultation, or tailored training just for your team contact salesdetails@threesl.com

Cyber Essentials

We were pleased to announce, earlier this month,  another successful assessment under the Cyber Essentials scheme.

We think this scheme helps instil confidence when dealing with online companies and would encourage all our customers to consider using it or similar.

We looked at the advances made in nuclear fuels by Framatome

We highlighted how 3SL provide a set of Q&A for anyone writing a tool evaluation. 3SL also wished well all those celebrating the new lunar year bringing in the Chinese new year of the Ox.

 

Happy New Year, I promise to…..

Whatever promises and resolutions you make we hope you manage to keep some of them. However, rather than some grand gesture of promising to give up chocolate bars and to do more exercise, we should also look at process habits that need to change. We’ve all got into the good habit of hand sanitising every time we enter a shop. The problem is when this habit / muscle memory becomes so engrained, we do it without thinking, a bit of disaster when you realise you are still wearing your winter mittens.

The same is true for business processes. It’s great when they become second nature, endemic, without having to refer to the policy again and again, but this can also be a hazard. If the situation, requirement or supply chain alters in some way, indoctrinated processes and solutions can be implemented without sufficient thought or review. So this new year make a note to ensure you check the mitigation still matches the hazard, the process is still suitable for the new requirements. If necessary plan and record exceptions and variations. Of course, use Cradle to record and track.

Training Courses

We are offering a number of public training courses. These are ideal for companies who don’t need a tailored course or have only one or two staff members requiring instruction. They are run on-line with a member of 3SL instructing. This year we will cover Requirements Management, Document Publisher and System Administration. The full calendar, and any updates,  are available here.

Brexit

3SL is fully committed to a continuation of supply of software, training and consultancy. We continue to work with our worldwide distributors and expect there to be little change as far as the end Cradle user is concerned. In the EU your data will either be handled by an EU distributor or by 3SL in the UK. At present all protections and EU data laws have UK equivalents. We will inform you of any changes where necessary should these laws and rules diverge in the future.

Cradle Release

Now in the final testing stages the new release (7.6) will be out soon – Watch for news. Those under maintenance will receive general updates and features for free. Those without maintenance or using single user products will need to purchase an upgrade to 7.6 from earlier point releases. We are also adding two new modules. You’ll be able to download an evaluation copy if you want to look at the  Risk Management and Test Execution and Recording features before purchasing a licence.

Oh Baubles!

Decorating a tree in the winter months has been a very long tradition. It has been used to celebrate Christmas by Christians since mediæval times, spreading from Northern Europe, through Germany. Popularity in the UK was driven by Queen Victoria from 1832 onwards. Fruits, berries, candy canes and biscuits/pastries have all been used to bring cheer over the years.   From the mid 1500s glass ornaments from Lauscha began to spread in popularity (Modern examples of the preservation of this art ). These artisan glass globes took much skill and time to create. From 1880 Woolworths started selling Lauscha glass ornaments, by 1910 these were available across the whole of the USA.

Engineering to the Rescue

Consumer demand required mass production techniques. Now millions of  these sparkly globes are available very cheaply. These days they are frequently blown or  injection moulded plastic. The story of the bauble is a typical demand led example of engineering product development. However, it has also been possible to scale up mass produced glass. Vitbis in Poland produces 200,000 baubles a day!. Some include very intricate hand crafted designs.

Office

The office Christmas may well be a bit different this year. Fears over handling decorations, being unable to disinfect the extra surfaces may well prohibit their use.  It may also be, as with 3SL, most staff are still working from home.

For a bit of fun Christmas paper engineering, you may like to download our DIY paper tree, for you own desk at work or home. ( Take a photo and Tweet it @threesl )

And here’s a bit of recycling – What happened to the little boy who ate the shiny streamers off the Christmas tree – He caught tinselitus! (If you want to read about the history of tinsel another Christmas manufacturing story see ‘a tinsel tale ‘ from  @festive_UK who manufacture miles of the stuff in Cwmbran.

Happy Christmas

May we take this opportunity to wish you, our wonderful customers, suppliers and distributors,  season’s greetings and a peaceful and happy Christmas. We wish you all the best in 2021.

Lookback

Well I don’t think any of us could have predicted 2020 would pan out the way it did. We know it has been tough for everyone and our sympathies go to all those who have lost someone dear.

And Finally

As you read this December 2020 newsletter, please take a moment to remember the many charities and causes that have struggled over this year, and if you are able, dig into your pockets.

Votes/Polls/Reviews

Well no one can say it hasn’t been an interesting month for politics. To start our November 2020 newsletter, we offer congratulations to Joe Biden, expected to be confirmed as the President-Elect of the United States.

Polls and votes are a method of gathering opinion. A consensus or agreement may be in a majority, or unanimous. Just as there is undeniably more than one way to run a country, there is usually more than one way to solve a requirement.  Configuration management is a method of recording the status of a project at a particular point in time. This could be a simple snapshot, but is more meaningful if there is a recorded agreement between stakeholders that a consensus was also reached. We term this a review, and you can read about why they are important in our article The Value of Reviews.

Cradle Review Options

Cradle reviews follow a workflow for each item type. That workflow is used  to control how an item after a review is allowed to proceed.

It’s unlikely you’d be able to mandate all electorate turn out to vote, and in the same way you can choose how many reviewers must make a decision. You certainly can’t ask all the electorate to vote the same way, and a review must allow you to accept a less than unanimous decision.

The supported options in Cradle are:

Reviewers required for decision –All, Any, Several, Majority, Most
Decision method – Unanimous, Any approve, Any reject, Majority, Most.

You can find out more information in Cradle Help

Results

At the end of September, Structured Software Systems Limited, completed its latest financial year.

Managing director Mark Walker said, “We are pleased to say that this has been our most successful year in 3SL’s 30 year history.”

highlights:

• • Turnover increased 15%,
  • Turnover split equally between 3SL here in the UK and our worldwide network of partners
  • Exports amounted to 67% of turnover
  • Our new SaaS services amounted to 7.5% of turnover in its first full year
  • Over 95% of customers renewed their maintenance
  • Every one of our customer feedback surveys compliments our support as among the best in the industry, both for responsiveness and depth of knowledge

We would like to thank all of our customers, both those new to 3SL and those we have been serving for 20 or more years. We continue to work to help you all to derive maximal benefit from Cradle!

Public Training Courses

Whilst 2020’s courses were all online, we will begin to look ahead to 2021’s public courses and offer as appropriate online or training room based sessions.

Public training options are ideal if only a few people in your organisation need to be introduced to a Cradle topic. It also allow you to share the experience with other users and there’s always the benefit that they may ask a question you’d not thought about!

Whether it is  Requirements Management, or Systems Engineering, Document Publishing or Loading our training can cover everything “Cradle” and the aspects of RM and SE. Of course we will create bespoke and in depth training for any customer who wishes to tailor training to their company process, however, if there is a topic you would definitely like to see offered in one of our public courses, please drop us a line: salesdetails@threesl.com

Back-To-School?

It’s been a challenging year for all. One of the biggest impacts has been in the education sector and we hope all students have now had a month to to settle into a new ‘normal’ as schools, universities and colleges return. Some have found the various lock-downs an opportunity to learn a new skill, study an online course or just get round to reading all those trade and profession journals that appear to mount in our in-boxes.

Learning should never stop, whether in the classroom, online, or as you work from your peers. One of the other vital learning opportunities is from evaluations during and after a project. Call it “Learn from your mistakes” or “Process improvement” the results should be the same; a closed feedback loop is essential. In Cradle you could add a new item type, add a frame to an item or set up a separate evaluations project. The important point is that the data coming out of the discussions and evaluations is recorded and linked to the items giving rise to that feedback. Too often ‘wash-ups’ can be seen as a tick in a management check-box. The lessons can be completely forgotten next time a similar project is undertaken. By recording this information linked to the original project, they can form input to your next design.

Cradle Release

We’ve held onto the current release Cradle 7.6, mentioned last quarter, in order to complete some performance enhancements. This means these improvements will be released at the same time as the new Risk Management and Test Execution and Recording features.

Staying Safe

We could write our own article about security and staying safe online when working at home, but we thought this article by the BCS – (British Computer Society) – said it all!

“All We Hear is Radio….”

Our August 2020 newsletter takes you back in time 65 years ago this month….

Do you remember the Tokyo Telecommunications Engineering Corporation? They  completed production of Japan’s first portable transistor radio the TR-55. It contained 5 transistors, which they developed themselves. Tokyo Tsushin Kogyo K.K. was renamed in 1946 to the more familiar Sony. The success is attributed to having that base level control – the design and development of their own transistors in addition to the circuit board. Transistors at the time didn’t have the characteristics or reliability or stability that they needed.

These days it is unlikely a consumer product manufacturer would set out designing their own discrete components. Customisation is done at a much higher level, as specifications to component manufacturer or firmware / software control on top. Knowing where to draw the line is crucial, knowing your own strengths and weaknesses is vital to your product’s success. On one hand there is no point re-inventing the wheel, but neither is there any point using less than optimal components if that is crucial to your design.

It is important to think about the problem first, rather thinking in terms of a solution. As we note in this article on Functional and Non-Functional requirements there are a number of ways to cross a road. There is little point designing a Belisha Beacon based system only to find that there is no power available at the site! However, if the specification does require lights your solution may need to include solar power – but it is unlikely you’ll be designing your own cells. However, if you are designing an electric vehicle, making your own batteries may be a world leading break through. Happy designing!

JOSCAR

3SL were pleased to announce their  JOSCAR accreditation . Using JOSCAR can determine if a supplier is “fit for business”. It is a collaborative tool used by the aerospace, defence and security industry to act as a single repository for pre-qualification and compliance information.

A Word from 3SL

Whether it is remote access to a SaaS solution, or building new processes or designing new products 3SL and Cradle are here to help. We’re ready and waiting to take your email / webinar request / call.  In other words, it’s business as almost usual at 3SL. Just because the staff are not all in the physical office we’re still ready and waiting to make sure Your project + Cradle = Success

We looked at the precursor to today’s 3 pin UK power plug. This initial design BS 546, was born out of the need to have a safety earth. The modern square pin version is still one of the safest plug designs in the world.
We reminded users there are different ways to view your data in lists, tables, trees or document views.

“I’ve got it, yes it’s so clear now. It was just when you said…….”

What we might call a water-cooler moment – a discussion with a colleague, sometimes about something completely unrelated, gives that neural spark.  An idea for a new project, a way to solve the current conundrum,  these interactions are often the start of a new path forward.
Aside from the fact, here up North in England, we call a ‘Water cooler’ the ‘Tap’, because that’s where water comes from. No fancy machine with a bottle atop!   With many people isolated in spare rooms and on dining tables some of these interactions will inevitably be lost. Arranging a video call is much more formalised and sterile compared to the often relaxed off the cuff old brew table.

How is your business ensuring ideas keep flowing? Are you back at work attempting to hold conversations 2m apart, or speaking muffled through a mask, or still working remotely? Zoom, Skype / Teams, GoToMeeting etc. may have seen a surge in use, but can they truly replace the water cooler interaction?

We think it is important to maintain social interaction as well as formal meetings. Some ideas you could try:

• Set up a Skype Group Chat amongst the office staff, called “Morning” and ask everyone to type “Hello”/”Morning”/”Yo!” when they ‘arrive’ at work, mimicking arriving at the office. You’ll inevitably get a few other light hearted text conversations which can help the team stay in touch.
• Choose to make an audio call to a colleague rather than a text or email. If you would normally have wandered over to a colleague’s desk to chat about an issue, then make the call. It is often easier to judge reaction by tone of voice than tone of text in an email ping-pong. Follow up with a summary email for traceability if applicable.
• Consider a virtual lunch. If you use video conferencing, once a week opt to have an open meeting. Make it clear this is definitely NOT a working lunch and just use it to mimic the break we should all be taking to replenish. However, if you want to discuss last night’s telly, or what Susannah has in her sandwiches today that’s perfectly fine.
• Play lists, if you are working from home the usual restriction of a music licence for the work premises would not apply, why not suggest your top 10 work-a-long  songs?
• Suggest your own social-customer@threesl.com

Discussions

We often leave notes for colleagues, whether as a sticky yellow square, or a text or social media message. Whilst these are very useful to record thoughts and reminders, they lack context. Cradle Discussions allows you to add thoughts and point to note database items. Whether it an action to complete, a question about the colour of a part or a lightweight review and approval mechanism, you’ll find them more comprehensive than a simple sticky.

It’s June Already

Life is certainly different since the last Newsletter. We’ve been locked away in bedrooms and dining rooms ensuring 3SL can continue to develop the upcoming 7.6 release and provide email support and webinars. A good thing about not having a webcam on your work computer, is that we can get away with t-shirt and shorts rather than normal office attire! Some staff are looking a little different, beards down to their knees, as they feel no need to shave, and that’s just the women……. We hope you too are coping with the changes.

 

Coming Soon……

As mentioned above Cradle 7.6 is lining up for release. We can’t wait to show you some great new facilities in Risk Management and Test Execution & Recording. Keep an eye out for release notifications.

A Word from 3SL

As lock-down eases, you’ll be getting to grips with the ‘new normal’, and making choices about the future of your business.

We just wanted to let you know we are right by your side, to help you navigate what’s next, with experience, support and technology to help. From remote access to a SaaS solution, to building new processes or designing new products in Cradle.

We have a range of online training courses. With a Document Publisher opportunity in June.

However, if there’s more we can be doing to support you, please let us know here. Let’s face the next steps together.

Spam Safe

We have recently updated authentication of our emails. Your mail systems should find communications from 3SL (threesl.com) make use of  DKIM (DomainKeys Identified Mail)  which adds PKI signature verification and  DMARC (Domain-based Message Authentication, Reporting and Conformance) – which combines SPF (Sender Policy Framework) and DKIM together. This should reduce the likelihood of 3SL communications mistakenly being marked as spam.

A Letter from our Managing Director

Training

Many companies have found that a tailored training course can help drive the most beneficial implementation of Cradle in their organisation. However, we are aware that sometimes this is not suitable. When you only have a couple of new people joining the team, a very small team, or you’d just like to get up to speed for an extended evaluation, a customer on-site course may be difficult to justify.

3SL are pleased to announce that they will be holding a number of public training courses. These will be tutor led and either online or in a common venue. There will be candidates from all companies wishing to take part. The first course is Requirements Management and is an online course in May, so can be followed at home during lock-down as long as you have an internet connection, a browser and Cradle. Your tutor will lead you through the course requirements, provide  exercises for completion and be available through the two days to answer questions and give guidance.

Twitter

We looked at where wear might be! With this tweet from Hardie Polymers.

We reminded our readers how they can re-create Microsoft® Word cross references in Cradle.

…and Finally.

Last month 3SL supported Circus Starr “The Circus with a Purpose” Founded in 1987 it is a touring circus that boasts world-class, professional artists from around the globe. It provides free seats for thousands of disadvantaged, disabled or vulnerable children, and helps raise much needed funds for local charities. It’s nice to put a smile onto someone’s face.

Woob-woob-woob, Aaaharrha! – Aaaharrha!, Ding-Ding, _waaaaAAAHAAaa_aa

Trying to find an onomatopoeic word for a siren, is a bit tricky (as you will see from our efforts above!). Warning – Warning! you have an extra day in February this year. Just in case you’d not realised the divisible by 4 but not 100, unless 400, means 2020 will have 29 days this February.  Now that you have been Alerted to that fact, we can use this as the most convoluted (so far this year) seg-way to  remind you about Cradle’s Alert feature.

There are no bells, whistles or sirens, and the most likely way you’ll know you have one is a reminder when you log into WorkBench. The tool bar across the top will show the number of new alerts you have. Alerts can be raised for all manner of things, from the Project Schema changing, to a new item being created or items being linked to items you own. You can see, read, clear them from the Alerts dialog. You can even send new ones directly to other users, “Gwendolyn – have you finished that review yet please?”. You can have Cradle create email alerts,  sent directly to a user’s in-box.  In summary, they are a useful tool to keep you up to speed with what’s going on in Cradle. More in depth information can be found in this post, or in the help. There are also a setting to control their accumulation.
