Factors that contribute significantly to scrum adoption as perceived by scrum practitioners working within South Africa organisationsHanslo, Ridewaan 05 1900 (has links)
Text in English / Scrum is the most adopted and under-researched Agile methodology. The research conducted on Scrum adoption is mainly qualitative. Therefore, there was a need for a quantitative study to investigate Scrum adoption challenges.
The general objective of this study was to investigate the factors that have a significant relationship with Scrum adoption as perceived by Scrum practitioners working within South African organisations. To achieve this objective a narrative review to synthesise the existing challenges was conducted, followed by the use of these challenges in the development of a conceptual framework. After that, a survey questionnaire was used to test and evaluate the developed framework.
The research findings indicate that relative advantage, complexity, and sprint management are factors that have a significant linear relationship with Scrum adoption. The findings are generalisable to the population, and the author recommends that organisations review the findings during their adoption phase of Scrum. / Council for Scientific and Industrial Research (CSIR) / University of South Africa (UNISA) / School of Computing / M.Sc.

Propuesta de mejora en la cadena de suministro de la producción de palta hass utilizando SC. Agility en Carac, Huaral / Proposal for improvement in the Supply Chain of Hass Avocado production using SC. Agility in Carac, HuaralParedes Robalino, Sebastian Omar, Guzmán Marcó, Angelo Fernando 04 August 2021 (has links)
Este trabajo de investigación está enfocado en la cadena de valor de la venta internacional de palta Hass de la producción obtenida de la ciudad de Carac, Huaral con la finalidad que los agricultores de esta zona pueden obtener mayores ingresos económicos.
Dentro de la zona se realizó un censo y se obtuvo como resultado que 12 de los 13 agricultores realizan venta de su producto directamente a un bróker.
Además, se tuvo como resultado todo el flujo de la venta, desde la compra de materias primas hasta el envío de la palta de forma internacional. Debido al resultado, se pudo identificar los procesos que realizan los agricultores y cuáles son los que realiza el bróker.
Con el fin de que el bróker no realice todas las funciones del flujo, se planteó que los agricultores tengan mayores procesos a su cargo, como son el de transporte y de la exportación, de esta manera el bróker se convertiría en un “agente de ventas”.
Se realizó una prueba piloto en un contenedor LCL y su rentabilidad fue de 100 dólares
En conclusión, los procesos se dividirán en 3 etapas: Compras, Transporte y Exportación. El bróker se encargará de conseguir las ventas internacionales y el ahora comprará las paltas a los agricultores a un costo mayor, teniendo como resultado un incremento de S/1.05 por Kg por parte de los agricultores. / This research work is focused on the value chain of the international sale of Hass avocado from the production obtained from the city of Carac, Huaral with the purpose that the farmers of this area can obtain greater economic income.
Within the area, a census was carried out and it was obtained as a result that 12 of the 13 farmers sell their product directly to a broker.
In addition, the entire flow of the sale was obtained, from the purchase of raw materials to the shipment of the avocado internationally. Due to the result, it was possible to identify the processes that farmers carry out and which ones are carried out by the broker.
In order for the broker not to perform all the functions of the flow, it was proposed that farmers have greater processes in charge, such as transport and export, in this way the broker would become a "sales agent”.
A pilot test was carried out in an LCL container, and its profitability was 100 dollars
In conclusion, the processes will be divided into 3 stages: Purchasing, Transportation and Export. The broker will be in charge of achieving international sales and he will now buy the avocados from the farmers at a higher cost, resulting in an increase of S / 1.05 per Kg by the farmers. / Trabajo de Suficiencia Profesional

Optické rozpoznávání tabule úkolů / Tasks Board Optical RecognitionSznapka, Jakub January 2016 (has links)
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.

Agile Planning Activities and Team Characteristics for On-time Delivery in Software Development Teams : A case study at EricssonOlander, Johanna, Qvist, Johanna January 2023 (has links)
The increase in complexity in software development is followed by higher pressure on several factors such as time-to-market. Software development projects are, however, found to often run over time due to many uncertainties throughout the project. Agile methodologies have become popular in managing software development projects due to their flexible, short-term, and iterative approach to working and planning. There is however a dilemma between being agile without fixed plans, and simultaneously having pressure from management and customers to set and meet a deadline, based on long-term plans. The Agile way of working includes self-organized teams that are involved in project management tasks such as planning and estimating. Agile teams create their own variances of different Agile frameworks as well as their own team characteristics, planning methods, and working ways. Important characteristics of Agile teams are, for instance, cross-functionality and adaptation. Agile planning includes activities such as the breakdown of work, effort estimation, prioritization, task assignment, and planning of iterations. These activities are commonly used in software development teams to manage their work and increase the ability to deliver on time. This study aims to investigate how software development teams plan their work in practice and what Agile planning activities and Agile team characteristics are regarded, by the development teams, to be important for on-time delivery. Furthermore, it is interesting to investigate how the identified activities and characteristics are reflected in the teams’ actual planning. A case study is conducted on two software development teams at Ericsson’s organization Cloud RAN to investigate this matter. The studied software development teams are found to use variations of Agile methodologies. The thesis identifies a number of Agile planning activities and team characteristics to be regarded, by the teams, as important for on-time delivery. Many of these activities and characteristics are also reflected in how the teams actually plan. However, there are some contrasting opinions regarding the activities and team characteristics. It can therefore not be stated that all the identified Agile activities and team characteristics are reflected in the actual team-level planning. The thesis also includes other findings impacting teams to deliver on time as well as factors affecting team-level planning.

Anpassning av Scrum-metod : För förbättrade mjukvaruutvecklingsprojektPrihodko, Jana January 2016 (has links)
Mjukvaruutveckling kräver bra arbetsmetoder för att man ska kunna leverera effektivt och välfungerande mjukvara. För att lyckas med detta behöves en bra arbetsmetod som de kan arbeta efter. Agila metoder blir mer populära att arbeta med när det gäller mjukvaruutveckling i dagens teknikföretag. Fler företag går över att arbeta efter agila metoder med projekt istället för den traditionella vattenfallsmetoden. Anledningen till detta är att fler och fler företag misslyckas att leverera projekten i tid med vattenfallsmetoden vilket medför mer kostnader för företag. Agila metoder hjälper däremot företag att få struktur som leder till bättre arbetssätt som i sin tur resulterar i att projekten blir avslutade i tid. Denna studie undersökte användning och anpassningar av agila metoden Scrum på en bank och om detta har medfört några förbättringar i arbete med mjukvaruutvecklingsprojekt. Undersökningen genomfördes med hjälp av intervjuer med Scrummästare, Agila coacher, produktägare samt chefer som arbetar med Scrum-metoden. Resultatet visar att agila metoden Scrum ger mer struktur samt transparens till projekt. Anpassningar till produktägarrollen på företaget har medfört att rätt uppdrag blir prioriterade och teamen får en tydlig backlogg att arbeta efter. Arbetet enligt Scrummetoden har hjälpt team att få en tydlig struktur och ökat leverans av projekt. / Software development requires good working methods to be to deliver efficient and effective software. To achieve this, companies require a good working method that they can work with. Agile methods are becoming more popular to work with when it comes to software development in today's technology companies. More companies are beginning to work with agile methods for project management instead of the traditional waterfall method. The reason for this is that more and more companies fail to deliver projects on time with the waterfall method, which means more costs for companies. The reason for this is that more and more companies fail to deliver projects on time with the waterfall method, which means more costs for companies. Agile methodologies however help companies to get structure that led to better work, which in turn results in that projects are completed on time. This study examined the usage and customization of agile method Scrum in a bank, and if this has led to some improvements in the work of software development projects. The investigation was conducted through interviews with Scrum Master, Agile coaches, product owners and managers who work with the Scrum method. The result shows that the agile method Scrum provides more structure and transparency to projects. Adaptations to the product owner role in the company has led to that right assignment are prioritized and teams get a clear backlog to work with. The work with the Scrum method has helped the team to have a clear structure and increased delivery of projects.

Unlocking Tacit Knowledge in Software Development : An Agile FrameworkMisgeld, Simon, Fredriksson, Erik January 2024 (has links)
Purpose: This study investigates how software development organizations can identify and utilize tacit knowledge effectively, aiming to develop a practical framework based on empirical data. By exploring methods for accessing and sharing tacit knowledge, the research seeks to enhance organizational efficiency and innovation in software development. Method: The study is conducted through a qualitative case study within a large software development consultancy. The analysis is based on 27 interviews, conducted with employees from the case company. These were later analyzed in a thematic analysis. Findings: We have pinpointed three barriers, alongside identifying three critical components for establishing a robust organizational framework for knowledge sharing. These include culture, empowerment, and practices. Additionally, we have categorized agile practices into socialization and externalization modes and evaluated them from a knowledge sharing perspective, investigating their respective benefits and utility for knowledge sharing in an agile software development organization. Theoretical contributions: The study adds to the literature on knowledge sharing and agile knowledge management. Providing a more practical, concrete, and defined view of how knowledge can be managed, especially in agile software development organizations and contributing with a comprehensive framework for creating a knowledge sharing organization. Practical implications: The practical implication of this study is that managers can better understand different agile tools and in which way they affect knowledge sharing in the organization so that they can be applied more accurately. The framework also provides recommendations for how the organization should be structured and different aspects to focus on to best support knowledge sharing and knowledge sharing practices. Limitations and future research: The most significant limitation is that the data was collected at one consultancy company operating in the software development industry. As such, the results might lack transferability to other industries. The study also lays a foundation for future research to go deeper into specific activities and see their effects. Keywords: Tacit Knowledge, Software Development, Knowledge Sharing, Knowledge Management, Agile Methodologies, Software Development Life Cycle.
