Diagnostic Flowcharts

Fault Finding Troubleshooting Flowcharts

Fault finding troubleshooting and diagnostic flowcharts have been used for a long time to capture and convey the steps required to help identify and repair faults. Using VisiRule, you can turn these fault diagnosis flowcharts into self-service interactive troubleshooting guides which can enable both qualified and unqualified people to diagnose faults and make temporary repairs. You can empower your existing staff members and field agents, and even your customers, to self-diagnose using fault finding flowcharts in a controlled and recorded way.


Decision Tree Flowcharts

VisiRule delivers fault finding problem solving resolution direct to the person who needs help on their own personal device using a dynamic sequence of interconnected questions.

Each answer helps determine the next question. Advanced calculations can be performed and complex logic evaluated. Pictures and videos can be incorporated to provide explanations and guidance.

Benefits of VisiRule Interactive Fault-Finding

  • reduce the time to problem resolution

  • reduce the accuracy of problem resolution

  • reduce the cost of providing informed product fault finding support

  • capture the faults logged and symptoms found

  • deliver informed guidance on mobile devices

  • provide links to the very latest product information

Self-Service Troubleshooting

Self-service troubleshooting is a powerful way of improving customer satisfaction. And it reduces the strain and workload on your own experts. Modern mobile technology provides an ideal platform for delivering self-help expert systems in a convenient and cost-effective way. With VisiRule, you can create fully automated decision trees for your help-desk agents and support staff, to ensure that customers always receive the correct response.

Intelligent Fault Finding: Detection & Resolution

Fault finding, or troubleshooting, can be best captured and represented diagrammatically. Using VisiRule Author, you simply draw the fault flowchart and it will generate an interactive question and answer web session. This session queries the nature of the symptoms present and directs users to a suitable diagnosis and associated recommended course of action.


Fault Diagnosis Flow Chart

You can map out the logic needed to diagnose faults using a flow chart or flowchart. A fault finding flow chart provides an excellent way to model and share the logic needed.

Interactive Troubleshooting Guides

Questions can have links to help files, manuals, KBs, images, pictures and other useful material. Users are only ever asked questions which are relevant and will contribute to an appropriate solution being found. Using the browser, they can go back and change their mind, and see what other questions and conclusions might be considered relevant. All of this makes for a rich, interactive walk-through of the troubleshooting process.

This works as both proactive and prescriptive maintenance.


Why Expert Systems?

Expert systems have been widely used over the years to help find faults in industrial and electrical equipment as well as deliver diagnostic advice in areas such as healthcare and customer support. Expert systems provide a systematic way to reason, extract, store and manage the expertise and know-how of senior personnel, engineers and management. This knowledge can then be used and shared with a wider range of less experienced or less specialist staff, and/or provided directly to consumers using simple interactive question and answer sessions.


Expert systems can interface to modern equipment and data feeds such as SCADA systems, PLCs and industrial controllers. Modern sensor technology and vibration data coupled with wireless or wired networks means that the intelligent remote monitoring and diagnosing of machinery is now viable. Intelligent diagnostic systems can shorten system downtime by helping identify worn parts and likely causes of failure BEFORE a part fails.


Knowledge Retention

Valuable knowledge can be shared and retained, even when staff members retire or leave. Prolonging the life of old equipment and being able to provide accurate and effective maintenance support systems can be aided greatly by VisiRule.

Decision Graphs - a lot more Powerful than Decision Trees

By allowing the merging of divergent branches within the diagnostic trees, VisiRule charts support paths which join up, so reducing the unnecessary duplication of sub-trees. This 'convergence' provides a far more compact representation than traditional decision trees which are prone to 'exponential explosion'.

VisiRule Troubleshooting Guide Features

Compound Logic

VisiRule supports compound expressions of arbitrary complexity as well as simple expressions. VisiRule also supports delayed logic where you refer back explicitly to a previous answer to a previous question.

Explainable Reasoning

Explanations can be attached to each step of the diagnosis to help guide and aid the user, and also to provide a way of explaining how a conclusion was reached.

Conversation Transcript

A record of each user session containing all the answers given, and any computations calculated, is made available along with the final conclusion reached for subsequent use. This can be emailed to the relevant department.

Pictures, Videos and Links

Explanations can be provided in the form of text, pictures, images, videos and links to relevant web pages.


Decision Analytics

Linking user sessions to analytics can provide insight into popular paths and frequently occurring problems, as well as spot emergent patterns. By capturing user feedback, and seeing which routes are most popular, it is possible to produce self-service systems which actually improve over time.
