- PostA Dive Into Manually Picked Seafood Distributing Warehouse Optimization An investigation of how to create more efficient manual picking processes in seafood distributing warehouses(2023) Widlöf, Matilda; Oresten, Tryggve; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Chalmers University of Technology / Department of Technology Management and Economics; Lantz, Björn; Lantz, BjörnSeafood distributing warehouses struggle with low efficiency. It is an industry where historically low focus has been placed on developing the warehouses capabilities meaning that they have typically lagged behind other industries. There exists plentiful literature on the best practice of designing ware- houses but none which tries to adapt the best practice to the particular circumstances of the seafood distributing industry, a gap this study aims to bridge. Through an abductive case study focusing on theory elaboration the specific context was understood. Literature was used to find the best tools to use for the setting and in the case of storage assignment strategy simulations were utilized in order to evaluate the best technique. The results of this thesis indicate best ways of designing warehouses when it comes to their shape, layout, batching method, zoning methodology, choice of pallet racks and storage location assignment method for article placement. Of special interest is the best storage location assignment method found by the study which solely utilized frequency of demand for allocating storage spaces, though there exist methods this study did not attempt which might be superior. The study investigated cluster based models incorporating association into the model but these were shown to be subpar. Practical consequences of implementing the guidelines presented by this study include a more resource efficient manually picked seafood distributing warehouse with shorter lead times and more efficient storage.

- PostA Framework for Increasing the Flow Efficiency in a Public Organisation through Operations Management Principles - A Case Study at the Swedish Migration Board(2014) Iversen, Carina; Louise, Sandén; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Chalmers University of Technology / Department of Technology Management and EconomicsThe public sector has a tradition of bureaucracy, political influence and conflicting stakeholder interests, which historically has resulted in that the public sector has fallen behind the industry regarding operational improvement work. The demand for more efficient processes in the public sector has increased and attempts have therefore been made to adapt successful concepts from the industry such as Operations Management principles. There are several examples where Operations Management principles within the private sector have been successful. However, the theory of applying Operations Management in the public sector is insufficient and requires further research. Therefore, the purpose of this study is to contribute with knowledge on how to increase flow efficiency in a public organisation by adopting Operations Management principles. This was done through an analysis of the asylum process at the Swedish Migration Board, hereafter referred to as the board, where the process was examined and evaluated and proposals for increased flow efficiency was developed. The board is a governmental organisation whose main field of responsibility is to consider applications from people who want to visit, live in, or seek asylum in Sweden and the focus of this study is the asylum process. With current conflicts around the world there is an increased demand for protection and the inflow of asylum seekers to Sweden have increased with approximately 50 % between 2013 and 2014. The board is therefore facing a challenge to meet the increased demand with acceptable waiting times, wherefore it has been requested to evaluate if the way of working is sufficient for the organisation. Based on the current theory, a conceptual framework was created in order to adapt Operations Management principles in public organisations. Based on the framework, an analysis of the current flow efficiency in the asylum process was conducted, and it was identified that the board has issues with high inventory levels in the system and thereby long waiting times in the asylum process. Moreover, there is a significant variation in the asylum process due to both internal and external factors that increases the total throughput time. The organisational design of the board is functional with a top-down decision making and control. The employees are organised in “silos” with deficiencies in both horizontal and vertical communication, which leads to limited insight in the work of others. Moreover, there is a lacking capacity of human resources that further increases the throughput times. The daily work is controlled by insufficient productivity goals that lead to sub-optimised processes and less ability for the employees to stop the process if defects are detected. In order to increase the flow efficiency a number of improvement proposals have been identified. First of all, it is urgent to reduce the inventory levels in the system in order to reduce false demands and increase the value adding time in the process. In order to do so, the performance goals must be changed, and the method should be controlled rather than the productivity. Furthermore, the variations in the system must be reduced, wherefore different flows with similar characteristics should be separated. Finally, the communication within the organisation as well as between the organisation and external operators must be enhanced. With these proposals, the flow efficiency can be increased in the public organisation through Operations Management principles.

- PostA Lean Transformation Journey - A Case Study of the Lean Implementation Process at a Medium-Sized Manufacturing Plant(2019) Boström, Martin; Olsson, Johan; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Chalmers University of Technology / Department of Technology Management and EconomicsThe fierce market competition has forced organizations to constantly improve in order to keep up with their competitors and increasing customer demands. Lean manufacturing is a popular improvement strategy for companies to embrace, as it aims to increase the customer value through the removal of wastes in production. However, embracing a Lean philosophy is far from easy, and an insufficient understanding of the Lean concepts and practices is a main cause of the failure rates of 80%. This study aims to investigate how Lean manufacturing can be implemented into a medium-sized manufacturing plant and the decisive success factors, to define a suitable approach for others who seeks to become Lean. Moreover, the research aims to identify the challenges that arose during a Lean implementation at Gunnebo Entrance Control S.p.A., and the process of solving them. The results and conclusions of this research are based on an extensive literature review of 65 publications, and a 5-month case study with daily interviews and 500 hours of observations at the shop-floor. To achieve the purpose, the authors have been involved in a Lean transformation project at Gunnebo Entrance Control S.p.A., a manufacturing plant in Lavis, Italy. The findings demonstrate that Gunnebo was successful in their Lean implementation which is based on improvements validated through increased capacity and improved space utilization, in combination with qualitative assessments from interviews and observations. The challenges faced at Gunnebo were closely connected to change management, which stresses the importance of Lean implementation projects not only possessing appropriate Lean expertise, but also expertise in managing an extensive organizational change. Furthermore, a holistic framework for a successful Lean implementation is presented to assist companies in Lean transformations. The framework suggests lower maturity Lean practices at an early stage to provide short-term success to overcome resistance, and higher maturity Lean practices once a robust Lean foundation has been set. Lastly, following the framework will result in different Lean practices for every company and it cannot be emphasized enough that a Lean transformation, like any other extensive organizational change, has to be adapted to the specific context in order to be successful.
- PostA Lean Transformation Journey - An Insulation Manufacturing Case Study(2017) Garcia Barillas, Angel; Read, Troy; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Chalmers University of Technology / Department of Technology Management and EconomicsElimination of waste in internal activities is key in improving operations in organizations. Tailoring and implementing Lean tools in order to focus on customers and achieve flow efficiency is the beginning of a Lean journey. For organizations to remain competitive they are continually searching for cost reduction, decreasing the lead-time in production and increasing productivity. This master thesis project is developed at an anonymous insulation manufacturing company, referred to as Insulation AB. This company has undergone a very abrupt change due to a high investment to increasing operations in the production department. The purpose of this master thesis is to investigate the present Lean implementation and the future steps that need to be taken in order to improve the production processes at Insulation AB. Implementing change requires following clear guidelines and adhere to time frames. For this reason it is important to understand management goals and sequences towards lean implementation. As the implementation will generate interaction between the shop floor and managers, it is important to identify the next step for improvement and the possible hindering factors that might rise in becoming a Lean company. Insulation AB managers, production supervisors, the continuous improvement team and shop floor workers were interviewed and observed in order to gather data to support the purpose and the research questions of this paper. This research outlines the importance of understanding the differences between the process manufacturing and assembly manufacturing industries for Lean implementation. This difference will affect the way of using Lean tools, implementing standardization and visualization, and analyzing product portfolio at Insulation AB. In order to identify the type company and operating conditions the product, manufacturing and production planning and control characteristics were identified and analyzed. The data collected from interviews and observations was organized between the Lean levels of interpretation to understand the path that Insulation AB is following. The Lean tools 5S, standardization, visual systems, total productive maintenance and continuous improvement were identified as the first steps of Lean implementation at Insulation AB. The framework showed that the company was following Lean tools, which supported the principle of elimination of waste. The next step identified for Insulation AB with their Lean implementation is to implement the principle: creative involve of the workforce and connect the company at all levels. An interactive Quality Management System (iQMS) is suggested to link the communication, documentation and strengthen the Lean implementation at Insulation AB, but requires cross-functional collaboration and communication to build a stronger Lean thinking culture.
- PostA Model to Determine and Improve an Organisation’s Configuration Management Capability(2018) Edberg, Mathias; Hæger, Mikkel; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Chalmers University of Technology / Department of Technology Management and EconomicsThis master thesis has enhanced the field of configuration management by developing a model that can evaluate an organisations configuration management capability. It also verifies that the already existing theory in the field of configuration management is applicable in industries where the main goal is to preserve and develop the operational capability of its assets. Solvina AB is a consultancy firm mainly working with clients in this industry. As a part of their service range, they advise clients in how to optimise their configuration management implementations to increase long-term operational capability and reduce project costs. This has become important for their clients in today’s global market as companies are continuously forced to increase operational eectiveness and eciency as markets grow more competitive. However, Solvina experiences dif- ficulties as there exist no formal evaluation process to evaluate the configuration management capability and identify improvement areas in these industries. Based on this background, this master thesis has firstly identified ten factors that are important to operate an ecient and eective configuration management. Based on these factors, an evaluation model has been developed. The model is simply a structured collection of activities that an organisation’s configuration management implementation can be expected to include in order to be successful. It can identify an organisation’s current configuration management capability and improvement areas. The model’s design and structure is based on the ability to vary the depth of the analysis to make it a useful tool for all organisations in the industry, independent on size and available resources. As future work, it is recommended that the model is further verified both with the practitioners of it and multiple interviewees to increase the granularity and reach the full potential of the model. Additionally, the data collection method needs to be further developed due to the barrier between the configuration management terminology and the industry terminology.

- PostA study of digitalisation-the development of swedish government agencies(2016) Blomgren, Sofia; Nybert, Natalie; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Chalmers University of Technology / Department of Technology Management and EconomicsThe Swedish government has set up a clear goal for Sweden to be the leading nation in utilising the opportunities offered by digitalisation. The ambition of becoming a leading nation does not only create a sense of urgency within government agencies but also communicates a vision of the future digital Sweden. The increased use of digitalisation affects all part of society, from citizens to the public administration. Swedish government agencies can not be excluded from this development and need to identify how to transform their organisation to the new digital era. The purpose of the master thesis is to describe how Swedish government agencies can successfully digitalise their organisation. In order to provide such recommendations, both external as internal challenges and success factors of digitalisation in Swedish government agencies was identified and further analysed. By comparing the challenges with the success factors, the authors could draw valuable conclusions on important steps for government agencies to take in order to make use of the possibilities of digitalisation. Minor studies were also described of Estonia, Finland, and the UK which are seen to be further ahead in their work of digitalising the public administration. The master thesis also identifies and highlights best practices of digitalisation and provides practical examples from government agencies with a high level of digital maturity. The empirical data identify the most prominent external challenges of digitalisation to be; information security, government law and regulations, the external change of digitalisation, and decentralised leadership. The internal challenges were; knowledge of digitalisation and digital maturity, benefit realisation, lack of leadership, system development and legacy system, culture and change management, lack of strategy, and fuzzy definition of digitalisation. Moving on to the success factors of digitalisation, the external success factors was seen to be; cooperation, and benchmark and best practices. The internal success factors were those present within government agencies, which were; clear and collective definition of digitalisation, digital strategy, culture for innovation and employee involvement, and customer focus. Based on the results, recommendations and specific action points could be given to government agencies striving to increase the use of digitalisation within their organisations. Swedish government agencies are recommended to increase the use of cooperation with external actors and other agencies, benchmark and identify best practices both nationally and internationally, establish a clear definition of digitalisation which can be communicated internally, formulate a digital strategy to guide the transformation of the agency, involve employees in the work around digitalisation and create opportunities for innovation, and finally to increase the customer focus
- PostA Sustainable Future with Autonomous Vehicles for Passenger Transport - The Means to Reach a Sustainable Future with Autonomous Vehicles through a Backcasting Approach(2019) Karlsson, Anna; Fredriksson, Emelie; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Chalmers University of Technology / Department of Technology Management and EconomicsToday’s transportation system is associated with a number of negative impacts when it comes to environmental, social, and economic sustainability. A prominent negative impact is the emissions of greenhouse gases from vehicles, contributing to climate change. With new technology like autonomous vehicles (AVs), a potential to transform the way transportation is done today into something more sustainable arises. Car manufacturers are paying more and more attention to AVs and it is likely that this new technology will be diffused into society in the future. The aim of this thesis is to lead the way and show how AVs can be used for passenger transportation in a sustainable manner. The thesis scope is delimited to passenger transport only and the geographical scope is limited to the city of Gothenburg. The contribution of this thesis is to provide an alternative for how to get to a sustainable transportation system in the city of Gothenburg in the future, with the market introduction of AVs. This is done by using a backcasting approach, where a sustainable future scenario, called our desired future, is identified in the first step. Our desired future is based on a robot taxi service, where nobody owns a car. The aim is to reduce resource consumption and to increase the utilization of the existing capacity, by minimizing the number of vehicles and even out the demand for transport. To provide a strategy for how to get to our desired future, gaps between today and the desired future are identified and leverage points for how to bridge the gaps are suggested. This is the first part of the thesis project. In the second part of the project, the gap incentives to not own a car is chosen to focus on. The chosen gap is seen as an important difference between the current situation and our desired future, it is possible to start working with already today, and it is crucial from a sustainability point of view, regardless of how long it will take until fully autonomous vehicles are available on the market. Part 2 aims to find a strategy for how to reduce the need for car ownership, to bridge the chosen gap, which would get us one step closer to our desired future. By using the design thinking methodology, a solution with the aim of decreasing the need for car ownership, called the taxi platform, is developed. The taxi platform gathers the existing taxi companies in an app and enables ride-sharing when beneficial. Hence, the taxi platform is like our desired future, but with drivers instead of AVs. A strategy for how to implement the suggested solution is provided in the form of a business model canvas.

- PostAchieving Strategic Improvements by Tackling Supply Chain Uncertainty. A lead time management analysis of an automotive manufacturer(2022) Olvenmark Holmström, Ossian; Härdig, Johan; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Dubois, AnnaThe automotive value chain is changing, and with that, the role of dealerships. Traditionally, car manufacturers have sold their cars to dealerships who, in turn, have been responsible for selling the cars to, and interacting with, the end customers. However, with new direct-to-consumer business models relying on online sales, the role of the dealership has transitioned from being a sales actor to becoming an intermediary preparing the cars and performing the final handover. Consequently, the car manufacturer’s supply chain has extended to include accountability of the dealerships’ operations and the lead time resulting from these operations. Based on internal investigations, the case company has identified what it perceives as unnecessarily long lead times in the dealership part of the supply chain. Therefore, the aim of this study was to provide insights and give recommendations regarding how to cope with the lead times and operations at the dealership stage of the case company’s supply chain. Accordingly, the study intended to support the work of improving supply chain management at the case company. The methodology of the study consisted of a preliminary analysis of the lead time issue, coupled with interviewing select market representatives. Subsequently, a survey was sent out to the same markets’ dealerships to make a complete and comprehensive assessment of the situation before a final analysis, together with relevant literature, of the results, was conducted. The approach was inspired by grounded theory in that it relied on empirical data without taking a starting point in a possible explanation. The analysis of the results points to uncertainties in lead times and quality, information flow, and customer adaptation, together with a lack of standardisation and directives. In particular, supply chain uncertainty prompts a trade-off between lead time and customer satisfaction since premature handover agreements with customers may result in rescheduling and, thus, risk customer dissatisfaction. The study shows that currently, customer satisfaction is prioritised in the trade-off. To conclude, the study results in five recommendations: Reduce uncertainties by improving reliability in lead times and quality, Develop guidelines on how to handle the trade-off between lead times and customer satisfaction, Investigate the lead time consequences of customer adaptation, Introduce coherent directives across markets, and Standardise market processes.

- PostActions to gain legitimacy in the Swedish financial sector A study of Swedish fintech startups(2018) Svensson, Christopher; Udesen, Jakob; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Chalmers University of Technology / Department of Technology Management and EconomicsThe financial sector has been undergoing changes the past decade and one reason behind this change is the development of the fintech sector. This new sector has brought new innovations that challenges the incumbents in the financial sector. The new entrants, further referred to as fintech startups, are focusing on developing services in short iterations that reflect the end customers needs. In addition, the fintech startups have a great focus on user experience. The incumbents have dictated the terms in the financial sector for decades and have managed to build regulatory barriers that makes it difficult for new entrants. This dynamic makes it challenging for the fintech startups to navigate in the financial sector in terms of how they should establish their service on a new market. Trust and relationships has historically been building blocks in the financial sector and are aspects that new entrants often lack. In addition, there is a need for legitimacy when operating in the financial sector, some of which is possessed by the incumbents, but also the fintech startups. This thesis aims to describe how Swedish fintech startups establish legitimacy when entering a new market to reduce the liability of newness related to their service. The establishment of legitimacy can be achieved both through internal and external actions for the fintech startups. This research presents different dimensions where actions was taken by Swedish fintech startups to gain legitimacy, these are: innovative, market, historical and compliance. Furthermore, this thesis presents how these dimensions can be gained, both internally for the fintech startup, but also externally through strategic alliances with incumbents. The relationships between the dimensions and different aspects of legitimacy is presented in a model in the end of the thesis.
