The second performance metric to assess is more intangible and pertains to perceived service level and customer and colleague interaction. In terms of colleague interaction this can be assessed through a variety of measures such as 360 degree feedback, line manager observation and self-reflection during a performance review. Research has shown that generally speaking individual employees are reasonably self-aware of their skills and capabilities and it is rare that a performance review highlights anything that the employee was not at least already aware of at some level. However the benefit of performance review is that it can demonstrate to individual employees specific areas where they could improve or would benefit from training to enhance their skills set. For example a food safety certificate to help ensure that an individual franchise was fully compliant with legislation, or perhaps rudimentary book-keeping skills to help ensure that the cash is managed accurately in each store.In terms of assessing Barista performance when interacting with customers this can be achieved through feedback forms and customer incentives. For example it is becoming increasingly common that receipts from retailers encourage customers to provide feedback about their service online. This has the dual benefit of helping the organisation to become more engaged with customers and response more rapidly to customer feedback. It can also be used to gather individual barista feedback if specific questions in the feedback questionnaire relate to performance and service such as speed and friendliness and helpfulness of the Barista. The information gathered from feedback surveys can be fed back to each barista in regular performance reviews in order to help them identify areas of development and subsequently improve performance. As noted at the outset of this section, performance management techniques should not be designed with the sole intention of discipline employees, although it is almost inevitable that at some stage a form of discipline may be required for certain employee. However, best practice makes it clear that regular performance reviews can help to forestall any such issues as if they are held regularly and reasonably frequently it should be possible to forestall any problems before they become issues of concern.
