In Module 6.01, we will delve deeper into the specific problem solving strategy of diagramming. You will be challenged to lay out the information in a way that is clear, and in a way that allows different elements of the problem to be shown by different parts of the diagram to reveal the solution to a given problem.
Network Diagrams
Network Diagrams
A network is simply a collection of objects (known as nodes) connected by lines. The nodes can represent places or people or tasks or any variety of things depending on the problem. The lines show how the nodes are connected, and can be accompanied by measurements or costs or limitations on direction or diverse data about the connection.
They are one of the most flexible and useful forms of diagram - and are particularly useful when a problem presents a number of options, only some of which are possible.
Tables
Tables
Tables attempt to lay out the information two-dimensionally, where looking across the page means one thing, and looking down the page means another. When laid out with due care, tables allow patterns hidden within rows and columns to become obvious, and allow you to concentrate on, or disregard, cells of the table as is necessary.
Freestyle diagramming
Freestyle diagramming
Many questions cannot be easily structured as tables or networks, and bespoke diagrams must be created.
When creating a diagram to represent you will need to:
ensure that you give yourself enough space.
use abbreviations - but ensure that you can tell which objects are which. Consider using a key if your abbreviations are unclear. Your diagram needs to be understandable by others too.
not be afraid to start with one type of representation and then morph into another. Such changes show your perception of the problem is growing.
