  1. G063 - Flowcharts

  2. Learning Objectives: • describe, interpret and create flowcharts, • explain suitability for use in a given application

  3. Flowcharts • are diagrams showing the breakdown of a system into simple steps • an algorithm • used during analysis • to show the processes in an existing system (current system) • used during design • to plan the order of processes for the proposed new system • to show how the new system should work • flowcharts can then be followed during development

  4. Flowchart Symbols

  5. Ordering food:

  6. Flowchart for having a bath: • Fill the bath with water • Get undressed. • Get into bath. • Wash. • Get out of bath. • Empty the bath water. • Get dressed.

  7. Flowchart for having a bath: • Fill the bath with water • Get undressed. • Get into bath. • Wash. • Get out of bath. • Empty the bath water. • Get dressed.

  8. Extended flowchart for having a bath: • you really would need to check if there is enough water and whether it is at the right temperature while running the bath. • Turn on the hot and cold taps. • Is it too hot or cold? If it is, go to step 3, otherwise go to step 4. • Adjust the hot and cold taps and go back to step 2. • Wait for 2 minutes. • Is the bath full? If it is, go to step 7, otherwise go to step 6. • Go back to step 4. • Turn off the hot and cold taps.

If it is, go to step 7, otherwise go to step 6. • Go back to step 4. • Turn off the hot and cold taps.

  10. Extended flowchart for having a bath: • Turn on the hot and cold taps. • Is it too hot or cold? If it is, go to step 3, otherwise go to step 4. • Adjust the hot and cold taps and go back to step 2. • Wait for 2 minutes. • Is the bath full? If it is, go to step 7, otherwise go to step 6. • Go back to step 4. • Turn off the hot and cold taps.

  11. Cruise control:

  12. Create a flowchart for the following scenario: • A customer books a collection of a parcel from a delivery firm • If the booking is made before 3pm, the collection is made the same day, otherwise it is made the next day • If the booking is made between 3pm Friday and 3pm Monday then it is collected on the Monday • When the parcel is collected, the customer is given a receipt • The parcel is then taken to the local depot • If the parcel is to go to the local area, it is left at the depot overnight • If the parcel is for another area of the country, it is sent to a different depot • The parcel is then put onto a delivery van • The driver attempts to deliver the parcel • If the recipient is at home, the parcel is delivered • If the recipient is not at home, the parcel is returned to the depot so it can be delivered the next day

  13. Greenhouse control: • click on the link below and draw a flowchart for the control process • www.bbc.co.uk/schools/gcsebitesize/ict/measurecontrol/0computercontrolrev4.shtml
