This paper investigates the impact of management training programs on garment clusters in Vietnam and Tanzania. The study found that in the medium run firms showed improvement once they had identified useful practices and adapted them to their operations. Although it takes a few years to experience a significant impact on incomes, management training can increase not just management scores but also incomes or value added.

While entrepreneurs play a key role in industrial development, the managerial capacity of those in developing countries seems limited. A number of randomized controlled trials have been conducted to evaluate the impacts of management training, coaching, or consultation programs. These studies found that the interventions had positive impacts on management knowledge and management practices, but the impacts on business performance measured in terms of sales revenue, value added, or profit were often statistically insignificant. Such mixed results may be attributed to experiment designs, including training content and the time elapsed till the follow-up observation. The present study attempts to substantiate this hypothesis by means of a randomized controlled trial of management training in Tanzania that targets 113 small manufacturers. As in some recent studies, it extends the observation period to three years to examine the trajectory of training impacts. Unlike many other studies, it is an impact assessment of training programs that covered quality control and production management as the training topics in addition to entrepreneurship, marketing, and record keeping. The treated firms made adaptive efforts to select useful practices and modify them to fit their business operation. It finds that the training effects on business performance are large and statistically significant, particularly in the medium-run. (C) 2018 Elsevier Ltd. All rights reserved.

We conducted a randomized controlled trial of short-term management training for small manufacturers in two study sites in Vietnam and collected follow-up data repeatedly for two years to assess longer-term impacts than the existing studies of management training. Our training programs introduced participants to Kaizen, a common-sense approach to production management. In both sites, many participants started to recognize the importance of learning about management and improved their management skills. The impacts on management skills were statistically significant two years after the programs. Our results suggest that the training program increased participants' value added in one of the two study sites, likely because they learned how to eliminate wastes in production.
