The competency-based movement in Sainsbury's, a PLC, is a process where assessors work with trainees to evaluate their competencies against predetermined sets and standards. This technique helps identify the competence level of employees, which aids in assessing the effectiveness of training programs. It provides deeper insights into company performance areas that are not developed yet, enabling the organization to undertake new training methods that improve employee proficiency. Furthermore, this approach helps Sainsbury's identify the need for new trainers, contributing to the achievement of organizational goals and objectives. The UK government's training initiatives also make a significant contribution to human resource development in organizations like Sainsbury's.
