    The impact of training and development on employee performance and service delivery at a local municipality in South Africa
    (Business Perspectives, 2022-10-13) Nama, Khuselwa; Daweti, Baphiwe; Lourens, Melanie Elizabeth; Chikukwa, Tatenda
    There is a growing concern about the lack of skilled municipal employees who can deliver essential services to under-resourced local communities in South Africa. However, coaching and mentoring appear underutilized to train municipal employees to improve service delivery to local communities. The study aims to investigate whether coaching and mentoring could capacitate municipal employees whose performance appraisal reveals a lack of skills to provide essential services. A cross-sectional research design was adopted to conduct a survey. The target population comprised 265 municipal employees, and a stratified random sample of 115 employees completed a questionnaire. The employees held positions of general managers, general assistants, and administrators, with varied years of experience. Cronbach’s Alpha indicated an overall high 0.8 questionnaire reliability score. Using a quantitative method, responses from municipal employees were collected to examine their perceptions of the influence of training and development on employee performance and service delivery. Hypotheses were tested using the bivariant inferential statistical tests of correlation (r) and Chi-square (χ2 ). The results indicated that training and development were more likely to improve employee performance. Furthermore, the results showed that trained employees were more likely to improve service delivery. In particular, coaching and mentoring could be used to improve performance. Therefore, the study found that the municipality was not providing employees with relevant training and development to enable them to address poor service delivery. Finally, the study recommends that the municipality invests in training and development to enrich employees with new skills and knowledge to improve the quality of service delivery

    Personal stress is maintained and measured by Machine learning. The device which is wearable has been used for the monitoring of personal self stress and data collection. In this research, it has been talked about the factors by which the physiological signal of the stress has been assessed. On the other hand, different type of technology has been used for the detection of the personal stress such as Electrocardiography (ECG) and many other devices. The observation and difficulties has been seen in this research by using this device and the technology. Stress disorder or ailment is one of the most common ailments in all individuals around the world. Stress and anxiety can greatly influence the life, emotion, behavioural pattern and thinking attributes of individuals. It is important to address this issue sooner or later. Psychological signal processing through machine learning effectively assists to detect the stress disorder at an early stage. The general system often considers some variables to detect stress. They are electrocardiogram, galvanic response, heart rate, respiration and many other elements. The ML tend to use algorithms to compare and contrast data to fetch effective e results. The paper has also carried out a statistical analysis based on three variables to fetch a proper result that provided the study group to comprehend a better understanding of the scenario. The researchers have taken the 'percentage of stress rate' cases' are considered independent variables whereas 'usage of a machine learning system' is considered a dependant variable.
