However, there are also documented studies, which are not common in the literature that uses these strategies to improve storage operations. This study shows the implementation of the Lean 5S Hybrid tool in the warehouse of a textile company based in Lima. The objective of the implementation was to improve productivity in the warehouse, as there were high response times when searching for materials, which reduced production time, warehouse redistribution, better using available space, and being able to strategically locate main materials. The results revealed an increase in warehouse productivity 3.95 times the initial one, an Inventory Record Accuracy of 98.17%, a decrease in the requirement search time by 66.12% (from 25 to 8 min), and stock rotation of 6.22 times.

In addition, the textile sector plays an important role because it presents a significant weight in the world economy. Likewise, this sector is considered influential when defining an international business agreement. Therefore, adequate management is required in the sector. Otherwise, it will generate a competitive disadvantage because the Peruvian industry is approaching an export recession. This paper proposes using the lean manufacturing methodology to reduce production times. The project is validated through a simulation of the current and proposed processes with the application of lean thinking tools to reduce waste (manufacturing process times).

Therefore, it is proposed to implement the Lean methodology, focusing directly on the optimization of production processes using its various tools and a selection of indicators for monitoring the results. To validate, a case study was carried out in a real company that implemented the different Lean tools and the Kaizen matrix in the dyeing and finishing process, a process that presents a high percentage of defects. This allowed us to effectively reduce the number of reprocesses by a significant 8.14%, which allowed the company to save $ 184,320.42.

The current demand of the plastic sector has been increasing, managing to exceed the productivity of SMEs in developing countries such as Peru. Within this framework, the demand is greater than the supply due to the low production of the companies, which present a high index of hours due to lack of maintenance of the machines. The purpose of solving the main problem is to reduce the hours of low productivity that represent a great monetary loss for the company. That is why, by implementing this maintenance management model that is based on Lean Manufacturing, it will allow for a broad competitive advantage in the sector. This model was validated by implementing the TPM and SMED tools of the Lean Manufacturing philosophy within the plastics plant, achieving results that determine the degree of improvement of productivity in the company. Finally, after having validated the model, it is concluded that it could increase the capacity used by the company by 20% with the reduction of the changes.

The sale of vehicles in Peru has increased by more than 6% only between the years 2016-2017, with Peru being one of the seven countries with an increase in vehicle fleet between these years, and it is also the fourth country with the highest sales, only after Brazil, Argentina and Chile. However, the post-sale service by the companies that provide these services currently does not meet certain essential aspects to meet the demand, one of the most outstanding, the delivery time, largely due to bad practices and capacity problems. of the concessionaire, generating considerable losses. Thus, this study developed a methodology to optimize the production of preventive maintenance services in automotive dealers applying lean manufacturing tools in order to reduce waiting times, delivery of vehicles at the wrong time and defective services. The pilot proposal was validated in one of the largest concessionaires of preventive maintenance service. The methodology reduced the lead time in two hours. The queues were reduced before each process and the percentage of vehicles delivered untimely from 28% to only 8% was reduced. In addition, the culture of good practices was implemented.

Erfarenhetsåterföring (EF) leder till flera fördelar som ökat resultat och nöjdare kunder. Det traditionella byggandet saknar en metod och modell för erfarenhetsåterföring. Det industriella byggandet har kommit längre i arbetet med erfarenhetsåterföring men generellt finns det utrymme för en bättre erfarenhetsåterföring inom byggbranschen. Inom tillverkningsindustrin arbetas det framgångsrikt med erfarenhetsåterföring genom ständiga förbättringar och Lean. Studiens syfte var att undersöka hur industriella byggare och tillverkningsindustrin arbetar med erfarenhetsåterföring och hur det kan implementeras hos en traditionell byggentreprenör. Genom frågan vad som skapar en bra erfarenhetsåterföring var målet att utforma en modell för implementering av erfarenhetsåterföring hos målföretaget Contractor. För att få inblick har en litteraturstudie genomförts, samt intervjuer med branschföretag.  Studien visar att de industriella byggarna arbetar med dagliga möten och det finns en eller flera personer med ansvar för erfarenhetsåterföringen. Inom tillverkningsindustrin använder de inte begreppet erfarenhetsåterföring även fast syftet och målet är detsamma som hos byggsektorn; att förbättra och nå ett högre resultat. Därför kan begreppet erfarenhetsåterföring användas i båda branscher men tillverkningsindustrin arbetar mer systematiskt. De har en starkare kultur och ser ett större värde i arbetet eftersom det är högre prioriterat. Det som visat sig skapa en bra erfarenhetsåterföring är först och främst när företagsledningen har en tydlig strategi kopplat till erfarenhetsåterföring. Det ska finnas en person som driver arbetet med erfarenhetsåterföring, en koordinator som skapar ett dragande efter erfarenheter. Strukturering av arbetet sker genom kontinuerlig användning av pulsmöten där avvikelser, förbättringar och planering diskuteras. Motiverade medarbetade behövs för att lyfta avvikelser och erfarenheter, där feedback och insyn i resultatet är viktigt för motivationen att rapportera. Avslutningsvis kan implementeringen av EF-modellen ske i ett pilotprojekt där arbetssätt med pulsmöten testas i en mindre skala för att sedan utvärderas och testas igen, för att sedermera fastställas. Det fastställda arbetssättet kan sedan spridas till fler arbetslag och till sist hela organisationen, där efterfrågande ledarskap fortsatt är viktigt. Det måste ständigt arbetas med frågan kring erfarenhetsåterföring, annars är den inte viktig. / Experience feedback leads to several benefits such as increased results and more satisfied customers. Traditional construction lacks a method and model for experience feedback. Industrial construction has come a long way in the work with experience feedback, but in general there is room for a better experience feedback in the construction industry. In the manufacturing industry, they work successfully with experience feedback through continuous improvement and Lean.  The purpose of the study was to investigate how industrial builders and the manufacturing industry work with experience feedback and how it can be implemented with a traditional construction company. Through the question of what creates a good experience feedback, the goal was to design a model for implementing experience feedback at the target company Contractor. To gain insight, a literature study was conducted, as well as interviews with industry companies. The study shows that the industrial builders work with daily meetings and there is one or more people responsible for the feedback of experience. In the manufacturing industry, they do not use the concept of experience feedback even though the purpose and goal are the same as in the construction sector; to improve and achieve a higher result. Therefore, the concept of experience feedback can be used in both industries, but the manufacturing industry works more systematically. They have a stronger culture and see a greater value in the work because it is a higher priority.  What has been shown to create a good experience feedback is first and foremost when the company management has a clear strategy linked to experience feedback. There must be a person who drives the work with experience feedback, a coordinator who creates a desire for experience. Structuring of the work takes place through continuous use of pulse meetings where deviations, improvements and planning are discussed. Motivated employees are needed to highlight deviations and experiences, where feedback and transparency in the results is important for the motivation to report. Finally, the implementation of the EF model can take place in a pilot project where working methods with pulse meetings are tested on a smaller scale and then evaluated and tested again, to be determined later. The established way of working can then be spread to more work teams and finally the entire organization, where in-demand leadership remains important. The issue of experience feedback must be constantly worked on, otherwise it is not important.

This article proposes a production method that aims to increase the manufacturing capacity of a footwear small- and medium-sized enterprise (SME) to reduce backorders. Therefore, an assessment is carried out and delays in production processes, excess product transport time, defective products, and inefficient work methods are identified. This article proposes designing a Lean manufacturing method using the change management approach, whose methodology is composed of six phases. In phase 0, change management is carried out; in phase 1, the company's current situation is reviewed using the Value Stream Mapping (VSM); in phase 2, the work area is reorganized (implementing SLP and 5S); in phase 3, production is balanced (implementing Line Balancing); in phase 4, continual improvement is established using the Kaizen tool; and finally, in phase 5, the results are evaluated. Through validation, it was possible to confirm that Lean manufacturing tools along with change management increased order deliveries by 82%.
