training and development or job redesign.

It is difficult to determine which is more effective at improving employee performance without having a specific context or goal in mind as both training and development and job redesign can be beneficial approaches depending on the situation. For example, if an organization is trying to improve the technical proficiency of their staff then investing in training and development might be the best option while if they are looking to increase overall efficiency within a certain process then job redesign might be the preferable route. Ultimately, it will depend on what objectives need to be achieved and how resources are allocated towards achieving them; however, both approaches can help foster growth within employees and should ultimately work together for maximum impact.
