These three considerations are said to be performance determinants. A performance cannot occur if the person is unwilling. If they do not have the capacity, for instance a phsycially disabled person faced with a clambering net and a rope to climb up, then they cannot perform.
If the person is not in the room where the performance is to be held, then they do not have the opportunity to perform. It all sounds obvious, but sadly determinants are not always rigorously applied.
Determinants of performance-willingness to perform: if employee is performing tasks and responsibilities in the organizationwith willingness level of the performance will be high andwill be up to the standards.2) capacity to perform: if the basic qualifications abilitiesand skills required performing specific tasks arepossessed by the employees the level of performance willbe in accordance with the set standards and vice versa.3) opportunity to perform: favorable circumstances andopportunities to perform the challenging tasks which aremore contributory towards achievement of theorganizations mission and objective can be reasons tohave more effective performance from employees
