UML Activity Diagram

In a UML model, the static representation of the system is a set of Class Diagrams (CD). Each class may have an associated Activity Diagram (ACD) to show the internal behaviour and/or algorithm for the class.

ACDs can also be drawn at any level in the UML model, to represent time sequenced behaviour at any level. The activities in the ACDs are intrinsically shareable, such that any given activity can appear on more than one ACD.

OK, we accept there may be a bit of poetic licence going on in this diagram, but it still shows how activity within a class can be represented. If you ever want a reminder of the legend of St. George it may be handy. For more information see the Cradle help section for ACD

National Tea Day – 21st April 2017

Support a Charity While You Have a Cuppa.

There are a number of ways you can get involved with National Tea Day www.nationalteaday.co.uk/ least of all you can ensure you get a good brew on for elevenses. Maybe nip out at lunch time and get a packet of scones and share afternoon tea with your work colleagues. Ask for donations in a Tea Cup and pick a local charity!

There’s an awful lot of Tea drunk by engineers at 3SL towers…….

Now the tricky bit, how on earth do we make this blog entry have something to do with Cradle? Ah! Multivalue Picklist Categories is how. If you have a set of premises that you manage, these can be set as items within Cradle. Each café could have a number of supplies that the café offers, and these could be recorded in a multiple value category.

If there was a shortage of Oolong, it would be simple to run a query to list each of the premises that need to be contacted. For further reading on categories, you could read ‘Multiple Value Categories’

Showing that multivalue categories can be used for everything, including tea

Happy Saint Patrick’s Day 2017

Wishing all our customers, suppliers and followers a Happy St. Patrick’s day 2017 from 3SL.

State Chart Diagrams (SCD)

Whatever process you are modelling, if there are stages or states that form the process you can represent these in a SCD.

Classes, in this case “a day” that have a distinct lifecycle. They exhibit a different external behaviour in different circumstances “Special day for celebration”  may be augmented by a Statechart Diagram (SCD).
An SCD is a finite-state-machine that describes how the class responds to external stimuli (the triggers here are the end of work on the 17th). The stimuli are the receipt of messages by instances of the class, in the form of calls of the class’s operations. Internally dynamic behaviour is described in terms of a set of states, (The status of the glass) the transitions between these states (Time for Another?)

Happy Pi Day 2017

Misunderstood Requirement Number 3.14159

“The system shall use Pie to calculate the….”

OK so it’s a homophone, caused by a typo. But misunderstood requirements can have a big impact.

Pi Day itself can throw up the question which part of the world do you live in? Today 14/03/2017 specifying in increasing component granularity dd/mm/yyyy is nothing like π. In reverse as UTC 2017-03-14T12:46:14Z again does not have any π significance. However, living elsewhere in the world, as long as it still used the Julian calendar, dates are written differently, if you swap the components to mm/dd/yyyy 3/14/2017 does have a meaning, although we have to skip back in time to 1592 to really tell the joke!

Writing unambiguous requirements is about being clear in your language, precise in your detail and knowing your audience. Otherwise you may end up with Pi on your face…..

According to piday.org Pi Day is celebrated on March 14th (3/14) around the world. Pi (Greek letter “π”) is the symbol used in mathematics to represent a constant — the ratio of the circumference of a circle to its diameter — which is approximately 3.14159.

Happy Shrove Tuesday (Pancake Day)

Have a great Pancake Day whatever your Process Flow!

Pancake Flow Diagram (PFD)

A (PFD) Process Flow Diagram, rather than Pancake Flow Diagram,  can be used to model Each Process Flow Diagram (PFD) shows a particular tasks or processes  that the system can perform. This is termed a flow. Systems may have many flows each of which may have simultaneous or optional elements.

Modelling the flow before you take action can ensure you have thought about, and documented the expected behaviour(s). It can be clear which parts of the system are operating in parallel and which could be bottlenecks awaiting the outcome of previous operations. However, modelling Shrove Tuesday’s pancakes may be a bit over the top…..
