2 What are systems diagrams for?
The audio track in this section provides an explanation of why diagrams are important tools in systems practice and some things to consider when drawing them. After you have listened to the audio track you are asked to draw a diagram that you may have encountered before – a spray diagram – to summarise the points that are made. So you need to be prepared to do this activity and I suggest that you gather together some sheets of paper of at least A4 size. You will also need either a softish pencil that is well sharpened and a soft rubber or a good pen before starting the video. I would advise against trying to draw diagrams on your computer or tablet until you have mastered the conventions and purpose of the diagram first. If you are unfamiliar with spray diagrams you can read the Diagram guidelines. Indeed, whatever your familiarity with spray diagrams I suggest you read these guidelines before starting the video.
Activity 2 Drawing a spray diagram about diagramming
Once you have read the Diagram Guidelines on spray diagrams listen to the following audio track on ‘what are systems diagrams for?’ Take notes while listening and then try drawing a spray diagram that summarises much of what I have been saying about diagramming, adding any other points that you feel are relevant.
Before you start you may want to look again at the conventions for a spray diagram. Also you should start your diagram around the middle of the sheet of paper. I mention that because most people automatically start writing in the top left hand corner and that’s hopeless for diagrams. It’s important to break the habit and to spread your diagram out as far as possible. In addition, don’t be surprised if you want to add to or change your first attempt. So, you may want to start afresh on a new sheet if you find that helpful.
Comment
I hope this activity has not proved too difficult. Certainly do not worry if your spray diagram contains less information than my example shown in the video. As with any skill it takes practice to improve and the main aim here is to show how a diagram can help with sense-making.
