111	Informal Knowledge Sharing : Grasping the Complexity of Sharing Knowledge in Ericsson’s Software Development Wittwång, Arvid, Perlind, Amanda January 2023 (has links) Many organizations have realized the importance of managing what they know in a proper way, with the sharing of knowledge as one of the most central aspects. However, the practices of knowledge sharing are seldom fully understood, and thus implementations of technical systems intended to improve knowledge sharing have less effect than expected. This master's thesis project identifies that the case company – the well-known, Swedish telecom giant Ericsson – suffers some potential knowledge gaps regarding its knowledge sharing practices, and the project thus serves the purpose to identify how and why employees indulge in sharing, with emphasis on the informal and employee-driven knowledge sharing. To understand and find ways to improve the knowledge sharing practices, the thesis project performs a case study in the rapidly expanding Ericsson Cloud RAN project. The qualitative approach of Multi-Grounded Theory is used, to focus on the perceived situation as described by the employees, with previous research as a second grounding-point. The qualitative data is collected through literature analysis, semi-structured interviews, and exploration of the digital platforms and tools internally used to share and document knowledge. The research identifies that the Cloud RAN project needs improvements of the knowledge sharing culture, and create a norm to reuse the documented knowledge. In spite of this, many employees appreciate shared knowledge and contribute to the common good of knowledge. A joy in helping others, personal benefits, and contributions to a greater good drive many employees to share. On the flipside are barriers such as a high bar for contributions from a technical point of view, and a risk of limited reuse of knowledge. As reuse is key to make use of knowledge sharing, the master's thesis report contains identified mechanisms realized in mock-up versions of tools and websites. There, emphasis is put on the importance of having proper tools and access to a contact network to navigate the documented knowledge. Summarized, the findings suggest to utilize the enthusiasm for knowledge sharing among employees for a supportive role, to champion a refined culture and lower the bar to contribute. Frequent reminders of available tools and the impact of sharing what is known in a good way, alongside creating awareness of the direction of the organization, can create company-wide awareness and motivations for improving knowledge sharing.

To do this a pipeline was built using a combination ofBERT-like models and T5 models for data generation. We then evaluated our generateddata using the downstream task of QA on a telecom domain data set. We measured theperformance using EM and F1-scores. We achieved results that are state of the art on thetelecom domain data set.We found that synthetic data generation is a viable approach to obtaining synthetictelecom QA data with the potential of improving model performance when used in addition to human-annotated data. We also found that using models from the general domainprovided results that are on par or better than domain-specific models for the generation, which provides possibilities to use a single generation pipeline for many differentdomains. Furthermore, we found that increasing the amount of synthetic data providedlittle benefit for our models on the downstream task, with diminishing returns setting inquickly. We were unable to pinpoint the reason for this. In short, our approach works butmuch more work remains to understand and optimize it for greater results ML Machine Learning NLP Natural Language Processing Ericsson Synthetic Data Generation Computer Sciences Datavetenskap (datalogi) Other Computer and Information Science Annan data- och informationsvetenskap
113	The Secret Writer Chaffe, Tomas January 2013 (has links) This essay reflects a particular method and way of working that I employ when undertaking artistic research. My artworks are rooted and develop from the situation I find myself in as an artist, the very context I exhibit the work within. I do this by trying to understand this position, both on the micro and macro scale. As an artist currently studying at—and subsequently exhibiting in relation to— Konstfack, I base my research with the physical manifestation of the school. An imposing building that was part of a huge headquarters and factory site for the telecommunication company, Ericsson, in south Stockholm. The title of my essay is from the translation of a unique German cipher machine, the Geheimschreiber, made known to me through enquiry into this site. Throughout the Second World War the German army used this machine to send highly encrypted military messages across Swedish telephone cables. Following one of the greatest accomplishments in the history of cryptography, a Swedish mathematician broke this German code and subsequently assisted in designing a deciphering machine on behalf of the Swedish Intelligence branch. This device, known as the App, was secretly developed and manufactured by Ericsson, possibly where I now study. In exploring the theme of secrets, this essay originates from an underpinning desire and subject of my work to reveal what is concealed or overlooked. Through researching and writing this essay I attempt to have a better understanding on the notion of secrets, in both the private and public realms. Introducing the artistic process and situation I am working from, I explore the central role that secrets play within society. In order to understand secrecy today I introduce the intertwined and associated contemporary debates of privacy, (both private and public) and transparency through such subjects as Google’s new privacy policy, mobile phone hacking, WikiLeaks and offshore banking. secrets artistic research artwork context site specific telecommunication Ericsson germany second world war Geheimschreiber cryptography apps Swedish Intelligence reveal privacy private public transparency Google privacy policy mobile phone hacking WikiLeaks offshore banking FRA FRA-law Simmel Telefonplan Midsommarkransen Tomas Chaffe Thomas Chaffe LM Ericsson apparat Vigo Lindstein Arne Beurling Professor of Mathematics Uppsala LM-staden LM-city Försvarets Radioanstalt phonehacking Sissela Bok Georg Simmel Cypherpunk Micah Sifry Wikileaks and the Age of Transparency orwellian freedom contemporary art interactive telephone Visual Arts Bildkonst
114	A Collaboration in Product Service System for Telecom Networks : An "Orange and Ericsson case" study Desai, Avni, Widgren, Maria January 2015 (has links) The purpose of the research is to study the “Orange and Ericsson case” while developing the method Actors and System Map. The interaction between actors within Ericsson’s Device Connection Platform is investigated in order to identify improvement opportunities in the interaction between the provider and the customer. To answer the purpose the following research questions was formulated: RQ1) What type of actors may be involved in a telecom related IPSO? RQ2) How can the connections between actors in the telecom related IPSO be illustrated? RQ3) How can the Actors and System Map method be refined? In order to answer the research questions different methodologies were used for the analysing process. The research started with a widespread literature study to collect knowledge related to the area of Product Service System (PSS) and methodologies for identifying how actors interact with one another. Studying different mapping methods the conclusion was made that Actors and System Map was most suitable for this study. In the methodology background the previous selected method, Actors and System Map from an Integrated Product Service Offering (IPSO) perspective, was examined in order to be able to refine and improve the mapping method. Actors Map provides a visual and clear overview of the actors involved while a System Map shows the information flows and activities between the actors. To understand the interaction between the two companies, the definition of IPSO and the importance of value-based selling for a service offering are described in the theory background. Also, different ways of looking at a business model within the telecommunication industry is presented. Obtaining information regarding making an Actors Map and a System Map an improved mapping method was refined. The adaption of the method was divided into eight steps. The refined Actors Maps of the DCP shows the actors involved, how they are connected and their main assignments from each respondent’s point of view at Ericsson. The refined System Map shows what kind of information is transferred between the actors within the companies and between Orange and Ericsson. Both maps delivered as a decision basis will help identification of non-value giving links and non-optimal distances in the information flow for both companies.

115	Optimizing the Supply Chain Performance at Ericsson AB : A Study of Lead Time Reduction and Service Level Improvement / Optimering av försörjningskedjans prestanda hos Ericsson AB : En studie om ledtidsreducering och förbättrad servicenivå Stenberg, Marcus, Larsson, Jesper January 2016 (has links) Ericsson has recently experienced difficulties to meet the customer demand, which has led to lost market shares. This is mainly due to the long and unpredictable lead times within their supply chains. Therefore, Ericsson seeks to increase their ability to meet the customer demand by reducing the customer order lead time. A shorter lead time would imply a greater responsiveness and improved service level towards the customers. A directive from the company was to base the study on the supply chain for the customer Algeria Telecom Mobile. The purpose of the study is to give recommendations for improvements that reduce the total lead time in a supply chain perspective in order to improve the customer service level. To be able to fulfill the purpose, four objectives were distinguished and supported with existing frameworks for analyzing supply chains. The first step was to create a current state map, which was achieved by conducting 24 interviews with people working within the supply chain. The second step was to identify potentials for lead time reduction. This was done by categorizing the supply chain parts and the problems that were gathered during the current state mapping into meaningful groups, and thereafter prioritize the categories with the greatest potential. The third step was to generate alternative solutions by conducting a second literature review based on the potentials that was identified during the prior step. The general solutions were later modified in order to fit the current supply chain. It resulted in eight Ericsson specific solutions. The fourth step was to evaluate these solutions in combination, which led to a recommended combination of solutions that provided the greatest lead time reduction. Also the requirements for implementing these solutions were presented in this step. The recommendation for Ericsson is to rearrange their current supply chain for the studied customer and use two different supply chains; the Regional supply chain and the Alternative supply chain. The two arrangements will both be based on the implementation of a supply hub, which implies a movement of the customer order decoupling point closer to the customer. The Regional supply chain will cover the main flow and be used when the customer orders products from a product portfolio that has been agreed within the region. The Alternative supply chain will act as a complement and cover the flow of products outside the regional product portfolio. The estimated customer order lead time for the Regional supply chain is 17 days, which is a reduction of 80 % in the normal case for the studied supply chain. The lead time for the Alternative supply chain is more difficult to estimate precisely, but it will be reduced in comparison with the current situation. Moreover, the service level towards the customer will be increased for both the Regional and the Alternative supply chain. To summarize the recommendations that are forwarded to Ericsson, they are listed below: <li data-listid="34" data-aria-posinset="15" data-aria-level="1">Implement a regional supply hub <li data-listid="34" data-aria-posinset="15" data-aria-level="1">Agree on a regional product portfolio <li data-listid="34" data-aria-posinset="15" data-aria-level="1">Implement time slots for inbound flows <li data-listid="34" data-aria-posinset="15" data-aria-level="1">Use BPO as a payment method instead of Letter of Credit <li data-listid="34" data-aria-posinset="15" data-aria-level="1">Use a CIP, DAP or DAT Incoterm <li data-listid="34" data-aria-posinset="15" data-aria-level="1">Implement a product configurator and let the customer place orders on commercial descriptions or a solution id. <li data-listid="34" data-aria-posinset="15" data-aria-level="1">Integrate processes and activities throughout the supply chain and establish a greater information exchange.
