Study Notes
Flow Charts
- A flow chart is a schematic representation of a process, using boxes to represent steps and their order with arrows.
- It guides maintenance personnel through a fault finding process using standard symbols.
- A simple flow chart includes symbols to signal the start and end of the process.
- The flow chart commences with the symptom of the fault and ends with an activity to repair.
Corporate Knowledge
- An organisation builds up a repository of knowledge acquired over a long period of time.
- Difficult faults are remembered, and when rectified, the process of solving the problem is rarely forgotten.
- Seeking assistance from senior trade personnel, supervisors, and Subject Matter Experts (SMEs) is highly encouraged when tasked with rectifying faults.
Brainstorming
- Brainstorming is a widely used technique for a small group to generate many ideas in a short time, often to improve a process or solve a problem.
- It is often more effective than individuals working alone in generating ideas to isolate a difficult fault.
- Brainstorming requires that everyone must contribute.
Fault Localisation
- The ‘half-split rule’ is an effective way to find faults by simplifying systems into a flow diagram or path.
- The flow can be either mechanical or electrical.
- The half-split fault finding process involves:
- Checking the complete system.
- Splitting the system into two halves.
- Checking each half individually.
- Further splitting the faulty half until the fault is isolated.

Description
Test your knowledge on flow chart symbols and processes. This quiz covers the basic elements of flow charts, such as symbols for starting and ending a process, and includes an example starting with a fault symptom and ending with a repair activity.
