Evaluation of Problem Driven Software Process Improvement

Carleson, Hannes, Lyth, Marcus January 2016 (has links)
Software development is constantly growing in complexity and several newtools have been created with the aim to manage this. However, even with thisever evolving range of tools and methodology, organizations often struggle withhow to implement a new development-process, especially when implementingagile methods. The most common reason for this is because teams implementagile tools in an ad-hoc manner, without fully considering the effects this cancause. This leads to teams trying to correct their choice of methodologysomewhere during the post-planning phase, which can be devastating for aproject as it adds further complexity to the project by introducing new problemsduring the transition process. Moreover, with an existing range of tools aimedat managing this process transition, none of them have been thoroughlyevaluated, which in turn forms the problem that this thesis is centred around.This thesis explores a method transition scenario and evaluates a SoftwareProcess Improvement method oriented around the problems that theimprovement process is aiming to solve. The goal with this is to establish ifproblem oriented Software Process Improvement is viable as well as to providefurther data for the extensive research that is being done in this field. We wishto prove that the overall productivity of a software development team can beincreased even during a project by carefully managing the transition to newmethods using a problem driven approach.The research method used is of qualitative and inductive character. Data iscollected by performing a case study, via action research, and literature studies.The case study consists of iteratively managing a transition over to newmethods, at an organization in the middle of a project, using a problem drivenapproach to Software Process Improvement. Three iterations of methodimprovement are applied on the project and each iteration acts as an evaluationon how well Problem Driven Software Process Improvement works.By using the evaluation model created for this degree project, the researchershave found that problem driven Software Process Improvement is an effectivetool for managing and improving the processes of a development team.Productivity has increased with focus on tasks with highest priority beingfinished first. Transparency has increased with both development team andcompany having a clearer idea of work in progress and what is planned.Communication has grown with developers talking more freely about userstories and tasks during planning and stand-up meetings. The researchersacknowledge that the results of the study are of a limited scope and alsorecognize that further evaluation in form of more iterations are needed for acomplete evaluation.

An exploratory study of manufacturing data and its potential for continuous process improvements from a production economical perspective

Todorovac, Kennan, Wiking, Nils January 2021 (has links)
Background: Continues improvements in production are essential in order to compete on the market. However, to be an active competitor on the market, companies need to know their strengths and weaknesses, and improve and develop their production continually. Today process industries generate enormous volumes of data and data are considered a valuable source for companies to find new ways to boost their operations' productivity and profitability. Data Mining (DM) is the process of discovering useful patterns and trends in large data sets. Several authors have pointed out data mining as a good data analysis process for manufacturing due to the large amount of data generated and collected from production processes. In manufacturing, DM has two primary goals, descriptive with the focus on discovering patterns to describe the data and predictive where a model is used to determine future values of important variables. Objectives: The objective of this study was to get a deeper understanding of how collected data from production can lead to insights regarding potential production economic improvementsby following the CRISP-DM methodology. In particular to the chosen production line if there were any differences in replenishment durations when it comes to different procedures. Duration in this study is the time the line is halted during a material replenishment. The procedures in question are single-replenishment versus double-replenishment. Further investigated was if there were any differences in the replenishment duration when it comes to which shift team and at what shift time the replenishment procedures were made. Methods: In this study the CRISP-DM methodology was used for structuring the collected data from the case company. The data was primarily historical data from a continues production process. To verify the objective of the study, three hypotheses derived from the objective was tested by using a t test and Bonferroni test.  Results: The result showed that the duration of a double-replenishment is lower compared to two single-replenishments. Further results showed that there is a significant difference in the single-replenishment duration between the different shift times and different working teams. The interpretation of the result is that in the short term there is a possibility that implementingdouble replenishments can reduce the throughput time and possibility also the lead time.  Conclusions: This study could contribute with knowledge for others who seek a way to use data to detect information or deeper knowledge about a continuous production process. The findings in this study could be specifically interesting for cable manufacturers and, in general, for continuous process manufacturers. Further conclusions are that time-based competition is one way for increasing the competitive advantage in the market. By using manufacturing generated data, it is possible to analyse and find valuable information that can contribute to continuous process improvements and increase the competitive advantage.

Reflecting and adjusting in large-scale Agile software development : A case study

Wahl, Emil January 2020 (has links)
Background. Agile software development has seen increased use in large-scale projects in recent times. Many larger corporations transition from using a traditional plan-driven approach for developing software to applying the Agile methodology within its processes. Large-scale Agile projects are inherently difficult to implement as there are many challenges associated with it. Many Agile frameworks have been developed to make it easier to apply the Agile methodology on a large-scale. The Agile principle of reflecting and adjusting at regular intervals can be used for developing these frameworks and allows practitioners to find ways to mitigate the challenges that large-scale Agile projects face. Objectives. This thesis aims to explore how a large-scale Agile project applies the Agile principle of reflecting and adjusting its work process, both at the overall and team level. The objectives of the thesis are to find out how the case organization regularly reflects on its work process and how it enables adjustments through the distribution of roles that can enforce changes. An additional objective is to find out what the perceived challenges are that are associated with performing regular reflections and adjustments in a large-scale Agile context. Methods. A field study is conducted at a large-scale Agile project. The field study includes direct observations of day-to-day work and scheduled meetings, interviewing project participants, and reading company documentation. The collected data is thematically analyzed to identify how the case organization reflects and adjust its work process and what the perceived challenges are. Results. Three different events are identified at the case organization to apply the Agile principle of reflecting and adjusting: reference groups to reflect on larger matters affecting much of the project, retrospective meetings to some extent to reflect within the different teams, and day-to-day reflections. All the identified roles can influence change for most parts of the process, but can only enforce change on their part of the process. Six themes are identified as perceived challenges associated with the Agile principle of reflecting and adjusting: Deadlines and time limits, multiple tasks within the teams, disinterest or misunderstanding the Agile principles, different levels of Agile, and established process and complacency. Conclusions. The case organization applies several different reflective events that address some of the challenges that are associated with large-scale Agile projects. The case organization has many other challenges relating to these events and they are all associated with other challenges previously discovered in related works. / Bakgrund. Agil mjukvaruutveckling har sett en ökad användning i storskaliga projekt under den senaste tiden. Många större företag övergår från att använda en traditionell plandriven strategi för att utveckla programvara till att tillämpa den Agila metodiken i sina processer. Det finns många utmaningar när man använder den Agila metodiken i ett storskaligt projekt. Agila projekt på stor skala är svårt att genomföra, och många Agila ramverk har utvecklats för att göra det lättare att tillämpa den Agila metodiken på stor skala. Den Agila principen att reflektera och justera med jämna mellanrum kan användas för att utveckla dessa ramverk och gör det möjligt för utövare att hitta sätt att tackla de utmaningar som storskaliga Agila projekt står inför. Syfte. Denna avhandling undersöker hur ett storskaligt Agilt projekt tillämpar den Agila principen att reflektera och justera sin arbetsprocess, både på en övergripande nivå och teamnivå. Målet med avhandlingen är att ta reda på hur organisationen regelbundet reflekterar över sin arbetsprocess och hur den möjliggör justeringar genom fördelning av roller som kan verkställa förändringarna. Ett ytterligare mål är att ta reda på vilka upplevda utmaningar som är förknippade med att utföra regelbundna reflektioner och justeringar i ett storskaligt Agilt sammanhang. Metod. En fältstudie genomförs på ett storskaligt Agilt projekt. Fältstudien inkluderar direkta observationer av det dagliga arbetet och schemalagda möten, intervjuer med projektdeltagare, och läsa företagetsdokumentation. Den insamlade datan analyseras tematiskt för att identifiera hur organisationen reflekterar och justerar sin arbetsprocess och de upplevda utmaningarna som relaterar till det. Resultat. Organisationen använder sig av tre olika sätt för att tillämpa den Agila principen för reflektion och justering: referensgrupper för att reflektera över större frågor som påverkar stora delar av projektet, retrospektiva möten i viss mån för att reflektera i de olika teamen, och dagliga reflektioner. Alla identifierade roller kan influera förändring på processen, men kan bara verkställa förändringar på sin del av processen. Sex teman identifieras som upplevda utmaningar förknippade med den Agila principen att reflektera och justera: Tidsfrister och tidsgränser, flera uppgifter inom teamen, ointresse eller missförståelse av de Agila principerna, olika nivåer av Agile, och etablerad process och självgodhet. Slutsatser. Organisationen tillämpar flera olika funktioner för reflektion som hanterar några av de utmaningar som är förknippade med storskaliga Agila projekt. Organisationen har många andra utmaningar relaterade till dessa funktioner och de är alla förknippade med andra utmaningar som tidigare upptäckts i relaterade arbeten.

Propuesta de mejora del flujo productivo en la línea de producción de fanales de una pyme dedicada a la elaboración y comercialización de productos a base de parafina

Córdova Cruces, Noel Francisco 27 September 2018 (has links)
Tanha Design es una empresa dedicada a la elaboración y comercialización de productos a base de parafina. Actualmente, la empresa tiene 2 líneas de productos (velas y fanales) y una amplia variedad de modelos y diseños en ambas categorías. Esta empresa se encuentra en constante crecimiento y comercializa sus productos tanto en venta directa como en venta de sus productos para eventos sociales y corporativos. Actualmente, los eventos corporativos son los que representan mayor parte de sus ventas. Las entregas de productos para los eventos tienen una fecha limite; lo cual conlleva a una problemática para la capacidad de la línea de producción provocando que en ocasiones se rechacen ventas. En el presente proyecto se analiza la línea de producción de fanales de parafina debido a que estos productos representan mayor ingreso para la empresa. Asimismo, la capacidad de esta línea de producción no puede satisfacer la demanda actual y para ello requiere de personal adicional y horas extras. Dentro del análisis preliminar realizado se identificó que las causas de la disminución de la productividad son la falta de estandarización en el proceso, una deficiencia en el flujo productivo y desorden en las áreas de trabajo. Con la finalidad de solucionar esta problemática se implementó las 5”S” y el estudio de métodos, y con ello poder mejorar la productividad de la línea de elaboración de fanales con el objetivo de incrementar la capacidad productiva y disminuir las ventas perdidas. / Tanha Design is a company dedicated to the elaboration and commercialization of paraffin-based products. Currently, the company has 2 product lines (candles and lanterns) and a wide variety of models and designs in both categories. This company is constantly growing and markets its products both in direct sales and sale of its products for social and corporate events. Currently, corporate events are the ones that represent most of their sales. Product deliveries for events have a deadline; This leads to a problem for the capacity of the production line, causing that sales are sometimes rejected. This project analyzes the production line of paraffin lanterns because these products represent higher income for the company. In addition, the capacity of this production line cannot meet the current demand and requires additional staff and overtime. In the preliminary analysis, it was identified that the causes of the decrease in productivity are the lack of standardisation in the process, a deficiency in the productive flow and disorder in the areas of work. In order to solve this problem was implemented the 5 "S" and the study of methods, and thus be able to improve the productivity of the line of elaboration of lanterns with the aim of increasing the productive capacity and decrease the lost sales. / Tesis

Strategies for Improving the Process of Lean Implementation in Health Care

Boudreau, Nathalie Lise 01 January 2019 (has links)
The Canadian health care system is a complex system under pressure due to an aging population. The annual health care budget has decreased, posing challenges for health care administrators. The purpose of this qualitative study, which was grounded in Deming's total quality management system framework, was to explore strategies 6 health care managers used to implement Lean initiatives to reduce health care costs in the province of Ontario, Canada. Data were collected through semistructured interviews and analyzed in accordance with Yin's approach, which includes compiling data, disassembling, reassembling, and interpreting data, and drawing conclusions. Four themes emerged from data analysis: the review of operational processes can reduce health care costs, specific management skills can reduce health care costs, employee engagement can have a positive impact on health care costs, and alignment can have a positive impact on health care costs. Findings from this study may contribute to positive social change by providing health care managers with successful strategies to improve operational processes and reduce health care costs, increase patient safety, and reduce negative patient outcomes. The results further contribute to positive social change by highlighting the importance of having employees participate in process improvement, which may improve employee and patient satisfaction in the community.
