Implementing the Pull Production System: An Action Research published by RAC-Revista de Administração Contemporânea

Context: there is little empirical evidence of the relationship between the implementation of lean techniques (such as the pull system) and their real effect on the performance of the supply chain.Objective: the purpose of this paper was to describe the process of implementing the production logic pulled in the supply chain, reporting the historical evolution of indicators, such as stock levels and lead limes over 23 months of intervention. Methods: an action research project was carried out describing the steps of the intervention in the chain between the years 2017, 2018 and 2019, divided into phases, that is: planning, data collection, implementation of the action, analysis and evaluation of the results. Results: the main contribution was to demonstrate that the production shift pushed to pull in the survey positively impacted the lead time, inventory and planning routines indicators. There was a reduction of more than 30% for the levels of inventories and about 40% for the lead-times in addition to the increase of the assertiveness of the sales forecast.Conclusion: the paper can be a possible reference for organizations that want to promote similar changes in their supply chains and significantly change the planning routine of their suppliers and distributors through the implementation of the pulled logic.

本研究的背景在于，关于精益技术（如拉动系统）实施与供应链实际绩效之间关系之实证证据寥寥。研究目标旨在描述供应链中实施拉动式生产逻辑的过程，并报告在23个月干预期间，诸如库存水平与提前期等指标的历时演变。研究方法为开展一项行动研究项目，描述了2017年至2019年间链条干预的步骤，分为规划、数据收集、行动实施、结果分析与评估等阶段。研究结果表明，推动生产转向拉动式在调查中正面对提前期、库存及计划常规指标产生了积极影响。库存水平降低了30%以上，提前期降低了约40%，同时销售预测的确定性也有所提升。结论：本研究可为寻求在供应链中推广类似变革并通过实施拉动逻辑显著改变供应商和分销商计划常规的组织提供可能的参考。
