8. Example
• Initial Question: Is remote working effective for professionals?
• Vague
• Improve by taking into account
• Population: the effect may be different for Construction managers than for Data Analysts
• Intervention: Home working or remote working
• Comparison: the effect may be different for Agile/Holacratic than for traditional working
• Outcome: “Effective” needs to be defined as the effect on performance is possibly different from
the effect on employee satisfaction;
• Context: the effect may be different for a Business School than for a Hotel.
• If you establish your PICOC, you can to determine if academic evidence is applicable to
your context.
