New features

Matrix Item Attribute / Navigation Filtering

showing teams that transitively link to a requirement
Transitive Links

In a standard matrix, would show as a fully populated grid. However, whilst Team A does provide part of Service 1, they do not provide the element which satisfies Requirement 7 or any part of Requirement 10. Those are provided by Team B.

Showing all links even those not desired
Complete Matrix

Cradle has always provided the facility to add textual attributes to the cross reference between items. In this example, choosing the link between Service 1 and Requirement 7 we could add Team A to note that Team A provides that element of the service. The new feature lets you filter the matrix results in the transitive cells by adding a Regex filter to the navigation being followed. This will look for a match between the attribute of the item and the text in the cross reference. In this case looking for the item Identity will give the following result.

Showing the results of filtering the item attributes agains the cross reference attributes
Attribute Filtered Matrix

Cross Reference Attributes

Allow restriction to a set of pre-defined values. Allow replacement or append behaviour when selecting from a list.

TLS

Upgrade OpenSSL and TLS to support TLS v1.3

Adaptations

An improvement in the behaviour dealing with pre-existing adaptation links.

Fixes:

  • Issue when importing change history with overwrite set to on.
  • The symbol resize handles were not working correctly.

Full details of the fixes in this release are in the Cradle help.

We asked you about subscription products. You answered our Mini Poll, and said that ‘horses for courses’ is the rule of thumb when selecting SaaS or conventional ownership. We’re happy to say Cradle is available in whichever guise suits your business.

Cradle Release

showing the setting up of matrix variables in a navigation
Navigation with MATRIX variables

The latest release of Cradle 7.4.2 contains a new Matrix feature. A matrix allows items linked items to be shown as a set of rows and columns with the cells representing the links between them. It is also possible to show the items in the rows linked to the items in the columns via a third item type represented in the cell. For example, rows representing requirements, columns representing results and the items in the cells representing the tests between the two. The new feature lets users filter the items shown in the matrix cells based on the value of a column or row item appearing in the cross reference attribute. This is set up as part of the navigation that is followed between items.

We have also upgraded our OpenSSL to use version 1.3 TLS.

There are a number of small bug fixes including diagram drawings, workflows, importing with overwrite.

As usual anyone with a current 7.4 code is entitled to download the latest release. Anyone with current maintenance is entitled to upgrade any previous version to this latest release.

clever engineering loo on the moveWe love keeping an eye on what’s new in the field of engineering. Did you realise how much the humble loo on the move has changed? #WorldToiletDay

We celebrated Saint Andrew’s Day  by constructing a COD (Collaboration diagram) showing how the Picts and Scots faced the Angles.

 

Happy Saint Andrew’s Day 2018

Wishing all our customers, suppliers and followers a Happy Saint Andrew’s day 2018 from 3SL

Whether a descendent of the Picts, Scots, or Angles, we hope the only battle today will be how best to model interactions in Cradle!

COD Collaboration Diagram

A Use Case is a class of interactions between actors in a UML model’s environment and the system. Each may be complex or compound and may require decomposition into simpler Use Cases. Each path through the possible options in a Use Case, (an  event flow) is called a scenario.

Scenarios can be described by a COD. This diagram  shows the details of the interaction of the environment and part(s) of the system.  On a UCD these are the external actors with the appropriate classes and their object instances. Each interaction is represented in terms of an exchange of messages. The COD focuses on clearly showing the totality of message transfers between all the actors and classes/object instances involved in the scenario. Similarly a SQD (Sequence diagram would be used to highlight the chronological ordering of the events.

Depicting the battle of Athelstaneford as a COD (Collaboration Diagram)
The Battle of Athelstaneford

Whilst the battle at Athelstaneford, is over simplified in this diagram, it still shows how a more detailed interaction of the whole Use Case can be illustrated. Therefore, if you ever want a reminder of why the Saltire of Saint Andrew was chosen as the emblem of Scotland…. The legend of the clouds vision to Óengus II COD diagram, may be a handy reminder. For more information see the Cradle help section for COD.

Remember, Remember

Firework

There’s quite a bit to remember this month whether it’s the  failed plot to blow up the Houses of Parliament, or the war fallen.

“Remember, remember, the fifth of November, Gunpowder Treason and Plot!” Might be a good way to cement a date in your mind we humans tend to like rhymes, songs, and mnemonics to help our brains ‘visualise’ an otherwise abstract date or fact. However, trying to remember what’s needed and when on a large project is really quite difficult. Especially when dates are not fixed.

query on a date in a category with relative offset
Relative Date Query

Cradle offers a number of ways you can track your project one of which is querying on relative dates.

For example an item representing a ‘test’ that needs to be run could be set with a category of type date. You could then query on ‘tests‘ that are due to occur (or should have occurred) before the end of next week. It is also possible to query on a range, say beginning of this month and end of next week.

For work breakdown items there are some built-in ranges which can be accessed on the Progress tab of query. This gives a planning view of where your project stands.

The Fallen

Remembrance

3SL join with our customers, friends and suppliers, on this armistice day,  to take a moment to remember those who have fallen fighting for their countries. There is a special poignance this year, the 100th anniversary since the signing of the armistice treaty between first world war allies and Central Powers.

Some of the new features in this release are:

    • Non-model item symbols have now been added to non-SysML diagrams. Item types (requirements and system notes and cross references are represented as ) Item symbols,  Link symbols and Context symbols.
      Non-model item symbols
      Non-model item symbols

      Details on the new symbols are below;

    • The link symbol will be the obvious connector which can be drawn between any item symbol and any diagram object that has a description. For example a specification / system note. Link symbols can only be connected to item and context symbols.
    • The context symbol represents the system note in a diagram but is a container within which other object symbols can be attached. This will show the existence of cross references between the context symbols system note and the descriptions (system notes, data definitions and specifications) accordingly.

Fixes:

  • Memory leak when querying RTF frames has been removed.
  • Cradle help now opens in the default browser for Web Access.
  • SysML reports now run successfully within consistency checker.

To download the latest release please visit our website at www.threesl.com and login. Once you have logged in navigate to the Resources section to download this release.

What is Engineering?

Engineering: (en-juhneer-ing)

The formal application of scientific and or mathematical principles to achieve a required goal.

This is quite a broad definition, there are many topics that are derived from the ‘pure sciences’ of  biology, chemistry, and physics and the mathematics behind them. Applying these sciences in different proportions gives us the terms we understand as engineering.  There are few ‘pure scientists’. Most professions require a mix with, say biology and chemistry to produce medicine or foodstuffs. Combine biology with physics to develop a space suit.  Physics and chemistry to produce batteries for your phone or car. Engineering is a mix of all these principles to solve problems and produce solutions.

Application of Science

As we, at 3SL, work (Software Engineers – application of logic and mathematical principles) there’s a construction site outside our windows. When you stop and think, there are a large number of principles being used in this civil engineering project. Definitely a lot of physics and mathematics, were used to calculate the safest ways to demolish the old building. A Police station, used to stand on this site. More science will have been used, by structural engineers, to calculate the forces and stresses in the new structure. A hotel and restaurant is to be built. Similarly the ‘Cast-In-Place’ 20m concrete piles that are being drilled into the ground will have chemical reactions occurring in the cement and ballast mix. These have been calculated and tested to produce the right strength pile to support the building.

You may not find much biology being applied on the site (save the organisms now living in the muddy puddles). However,  the chemicals used in the building from water pipes to paints will have had biological studies to ensure they are human safe, or how to use them safely.  Although,  when we have watched the seemingly graceful ballet of the excavators, diggers and trucks we can’t help feeling that the movements and joints were based on mother nature. The human and the control systems they operate, produce movements and operations which make it hard not to anthropomorphise the JCB!

Discovery and Development

The principles used in engineering are or have been, observed empirically, calculated mathematically. They are then proven or developed by experimentation or modelling. The results are recorded and can be used in the next application. Therefore, that field of human endeavour moves forward. Whilst each engineering task will have a new goal, the principles that are applied will be based on the underlying sciences. The old building, that was removed, had different foundations from the new one. Development and testing move our engineering forward. We achieve more as knowledge and principles are built upon.

Application

Engineers need to understand the principles they are applying. Whilst these may be at very different levels, they still require planning and thought. No one would expect the building  to be produced by pressing one button on an ‘app’, but neither would you expect the civil engineers and architects to start experimenting with concrete mixes for every building. That’s not to say that there isn’t a group of engineers experimenting with different carbon fibre additives to give the concrete more strength at a reduced weight; their results being fed upwards to the building design engineers of the future.

Process

The formal application of these scientific principles, is how problem solving engineers meet the requirements. We know this as a design process. The whole being a ‘system’, this is systems engineering.  From the initial ideas and requirements management to the finished article, this engineering step is as crucial as the science principles upon which the solution relies. What ever engineering discipline you are in we hope you’ll agree, from concept to creation Cradle is the best tool you’ll see!

The Tail End

Whilst we agree that every job and every individual in our society plays an important role. There has been a bit of dilution of the ‘Engineering’ term in recent years. There’s a tendency for anything that is remotely technical to be labelled engineering. Anyone who understands which end of a screwdriver to hold gets called an engineer. Whilst I agree that there are chemical and physics principles afoot when I place the food in the pan for tea (dinner if you’re not from up North) and when I use the washing up liquid to clean the dishes, I don’t label myself a Domestic Engineer 😉
