We all want a “genius” to help us

A “genius-bar” mentality to problem resolution with an increased demand for

fast and accurate problem solving


A fundamental shift in the support mission

• There’s a greater variety of “things” to support.

• The emphasis is now on users’ ability to access data from any device, rather than the device itself.

Top skills needed


Troubleshooting six steps

1. Identify the problem – Question the user and identify user changes to computer and perform backups before making changes

2. Establish a theory of probable cause (question the obvious) – If necessary, conduct external or internal research based on symptoms

3. Test the theory to determine cause – Once theory is confirmed determine next steps to resolve problem

– If theory is not confirmed re-establish new theory or escalate

4. Establish a plan of action to resolve the problem and implement the solution

5. Verify full system functionality and if applicable implement preventive measures

6. Document findings, actions and outcomes

Some closing thoughts…

Working definition of digital skills qualifications:

“The very broad set of skills that individuals need in order to understand, use or create the software and services we all access through devices such as computers, tablets and ‘smart’ phones.”
