A randomized controlled trial of short-term management training for small manufacturers was conducted 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.
The 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. The 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
Kaizen score, willingness to pay for the training program and firm's added value.
For firms in the knitwear industry, both the in-class training and on-site visits alone led to higher adoption of Kaizen practices two years later, with those receiving the two components not showing greater adoption than those getting only one of the two. For firms in the knitwear industry, the higher adoption of Kaizen practices only led to increases in value added for those that got on-site visits, regardless of whether they also got the in-class training or not.The increase in value added seems to be driven by a reduction in overproduction, as the dead output decreases in firms that had access to the consulting sessions. The effects on the value added for firms in the knitwear industry did not show immediately after the training, but two years later. For firms in the steel industry, only the combination of the two components (in-class training and on-site visits) led to sustained improvements on the adoption of Kaizen practices.The larger take-up of Kaizen practices did not translate into higher value added for firms in the steel industry.For all firms, access to the programme increased their willingness to pay for similar o ne in the future, with this effect being stronger for the knitwear firms (consistent with the programme being more suited for them)
