July 2020 Newsletter

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

Watercooler based on image from publicdomainvectors.org

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


Remember to use #Cradle discussions
Remember – 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.


Public Requirements Management Course coming in October, and Document Publisher in November – For this year’s calendar see Public Training Courses 2020 Of course if you would like your own bespoke training, we can arrange it, please contact support@threesl.com

June 2020 Newsletter

It’s June Already

 Photo by GEORGE DESIPRIS from Pexels

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……

Risk RAM and TER Test Execution & Recording
Cradle 7.6 Teaser

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.

Got Mail

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.

VE Day 75 – May 2020

8 May Victory in Europe Day

VE Day 75 logoThis day celebrates the formal acceptance, by the World War II Allies,  of Nazi Germany’s unconditional surrender of its armed forces in, 1945.

2020 marks the 75th year since this historic agreement was reached, ending years of battle of an unprecedented  scale. However, it was a further three months before fighting ceased in Japan.

There are many fewer people these days with personal memories of the conflict and the final resolution. These special days help us remember the sacrifices made by so many on behalf of the countries for which they fought. Hopefully we learn from the problems of the past and use it to guide us to a peaceful future.

Today VE Day 2020 – 75 Years

Today, of course, we have a different solider, the care worker, battling a different kind of enemy. So please make your celebrations of VE day known, but do so safely #StayHomeSaveLives. In memory of all those who, fought and died 3SL salutes you.

Earth Day 2020

An Earth Day Like No Other

Based on 3SL logo and Photo by ATC Comm Photo from PexelsIt’s 50 years since the launch of Earth Day, and now nearly 200 countries coordinate a celebration of our fabulous home, with an important message that we need to look after it.

We may be the current custodians of this planet, but we share it with many. To them and ourselves, we have a duty of care. This year more than ever has demonstrated our own fragility. It’s demonstrated how we’re maybe not as invincible as we like to believe. Nature can be a strange beast. Whilst we may not be able to control nature, we can do our bit to care for what we have and ensure we don’t damage it.

As designers,  manufacturers and producers we need to consider how and whether what we engineer is beneficial and as non damaging to the environment as possible.

Whether you decide to; pick up that bit of litter on your exercise walk; choose a lower carbon or no meat meal; print double sided paper; leave the light off and the curtains open longer we can all make a difference. If the project you are working on uses resources, make sure you build environment requirements into your design. Make sure they assess and where possible lower the impact of the solution you choose.


Covid-19 Good News Blog Update
