Consequently, the sector’s production was reduced by PEN 1,200,000 while demand remained flat. Thus, this article proposes a production control model using 5S, Single-Minute Exchange of Dies, and tools such as Kanban and Constant Work-in-Progress (CONWIP) to increase the productivity of a sand casting line in a Peruvian metalworking enterprise that manufactures parts for mining on request. The improvement proposal involves the implementation of lean manufacturing tools and analyzes low productivity effects. The problems identified are typical of the Peruvian metalworking sector; thus, this study may contribute to finding possible solutions for issues faced by other enterprises. / Revisión por pares

The purpose of this study is to investigate the relationship of two significant concepts withinthe manufacturing industry. Namely, the widely popular Lean production and the arising Industry 4.0. The lack of a common framework concerning their relationship requires further exploration, as stated by several researchers. For companies to stay competitive within a changing market it is of importance to adapt to new technologies, indicating that the understanding of this relationship is essential, as Lean production is extensively used in industries today. To increase the understanding of the concepts and their relationship three research questions were formulated, as followed: RQ 1: How can Industry 4.0 support Lean production? RQ 2: How can Lean production support the implementation of industry 4.0? RQ 3: What are the challenges of implementing Industry 4.0 in Lean production? The study was conducted using qualitative research methods such as the narrative literature review and thematic analysis, allowing for the identification of themes and structuring of the study in a narrative approach. Second-hand data was collected through academic databases using search terms highly relevant to the research questions. The theoretical framework of the study provides a foundation for the understanding of the concepts. Whereas the results are centered around the relationship of Industry 4.0 and Lean production with themes relevant to the research questions and subthemes to follow. The analysis highlights important aspects of the results in relation to the theoretical framework, while also discovering insights connecting the research questions together. The conclusion presents aspects of how Industry 4.0 technologies can support Lean production through factors such as increased continuous improvement, support of people, improved JIT, Kanban, maintenance and communications. Where the general benefits will be productivity, quality and speed of introducing new products, adapting to high variability of market demand. Furthermore, describing how Lean production can support the implementation of Industry 4.0, as the degree of Lean maturity directly influences the efficiency of Industry 4.0 implementation. The employment of Lean principles such as continuous improvement, focus on people and standardization can result in a more effective implementation and utilization of Industry 4.0. Challenges of implementing Industry 4.0 in Lean production such as the risk of counterproductive implementation because of the lack of common framework, limitations of certain Lean practices, Lean professionals and ICT professionals limited knowledge of eachother's fields and the understanding of how to apply Industry 4.0 based on lean principles. Lastly, recommendations are offered for companies aspiring to implement Industry 4.0, as they should evaluate their current level of Lean maturity in order to understand when it is most efficient to incorporate the new technologies. Companies seeking to aid their Lean objectives should concentrate on technologies such as IoT and CPS as they seem to have the most positive impact on Lean. In addition, recommending further research regarding the relationship of Industry 4.0 readiness and Lean maturity, exploring which degree of Lean maturity to efficiently integrate and utilize certain Industry 4.0 technologies and when to implement certain Industry 4.0 technologies to aid the advancement of Lean maturity.

The master's thesis deals with the optical recognition of the tasks board in the agile environment. Based on theoretical knowledge about the agile project management, the concept of the task board is introduced. Possible representations of this agile tool are discussed, as well as their advantages and disadvantages. In connection with the optical recognition of the objects, follows the theoretical part dealing with barcodes, their structure and methods of detection and decoding. Based on these facts, the application design is reflecting all the needs specified by the company Siemens CT DC which is the contracting authority of the project. Implemented solution used for synchronization between the physical and virtual task board is able to detect the task cards with reliability about 95 % and allows the full synchronization of the task board during the four cycles. Deployment in the software development team and using the fully automated mode brings approximately five times quicker synchronization than it was before. In a case of semi-automated mode, it is about three times faster than before.

In today’s knowledge-based economy, modern organisations understand the importance of technology in their quest to be considered global leaders. South African markets like others worldwide are regularly flooded with the latest technology trends which can complicate the acquisition, use, management and maintenance of software. To achieve a competitive edge, companies tend to leverage agile methods with the best possible combination of innovative supporting tools as a key differentiator. Software technology firms are in this light faced with determining how to leverage technology and efficient development processes for them to consistently deliver quality software projects and solutions to their customer base. Previous studies have discussed the importance of software development processes from a project management perspective. African academia has immensely contributed in terms of software development and project management research which has focused on modern frameworks, methodologies as well as project management techniques. While the current research continues with this tradition by presenting the pertinence of modern agile methodologies, it additionally further describes modern agile development processes tailored in a sub-Saharan context. The study also aims novelty by showing how innovative sometimes disruptive technology tools can contribute to producing African software solutions to African problems. To this end, the thesis contains an experimental case study where a web portal is prototyped to assist firms with the management of agile project management and engineering related activities. Literature review, semi-structure interviews as well as direct observations from the industry use case are used as data sources. Underpinned by an Activity Theory analytical framework, the qualitative data is analysed by leveraging content and thematic oriented techniques. This study aims to contribute to software engineering as well as the information systems body of knowledge in general. The research hence ambitions to propose a practical framework to promote the delivery of quality software projects and products. For this thesis, such a framework was designed around an information system which helps organizations better manage agile project management and engineering related activities. / Information Science / Ph.

Since the early 1990s lean manufacturing has been employed by companies looking to reduce costs, increase efficiencies and improve quality. Academic studies of the financial benefits of lean manufacturing are mixed in their results, where some show benefit and others do not. The objective of the current work was to confirm a financial benefit of lean manufacturing, while also establishing whether such a financial advantage was sustainable. Financial data was collected for a large number of companies in the manufacturing sector, over the period from 1990 to 2010. The data were used to show correlation between inventory turns and return on assets (ROA), where turns were a measure of the leanness of a firm or an industry. A positive correlation between turns and ROA showed evidence of financial benefit from lean implementation, confirming previous results from a smaller-scale study. It was then shown that about 45% of firms studied had a competitive advantage that could be attributed to their level of leanness. Firms with a competitive advantage were compared to peer companies and it was found that about 60% are able to sustain their competitive advantage for more than 10 years.
