A common debate I have, Compliance vs Competence, what is the difference?
Is simply being compliant enough?
Does a ticket equal competence?
And how is competence measured?
Compliance is ‘acting in accordance with health & safety rules and legislation’.
Compliance is a minimum requirement, while competence goes above and beyond that.
The definition of competence from the HSE website: “To be competent an organisation or individual must have sufficient knowledge of the tasks to be undertaken and the risks involved. They must have the experience and ability to carry out their duties in relation to the project, to recognise their limitations and take appropriate action to prevent harm to those carrying out construction work, or those affected by the work.”
Competence develops over time.
It is a mix of initial and on-job training, instruction, assessment and formal qualifications.
The difference between compliance and competence can be thought of as: Passing and getting your driving license you are compliant; you know how to drive and all the rules and road theory. But are you a competent driver? You are now on your own and putting the knowledge you have learned into practice. But without experience you are only compliant.
For further information on the courses that Pragmatic Consulting offer please visit https://www.pragmatic-consulting.co.uk/ or contact Jo Niblett (Managing Director).
