In an era where the network of interconnected devices is rapidly expanding, it is difficult for organizations to adapt to the increasingly data-rich and dynamic environment while remaining competitive. Employees experience that much of their time and resources is spent daily on repetitive, inefficient and mundane tasks. Whereas lean manufacturing has manifested itself as a well-known optimization concept, lean information management and the removal of waste is not yet being used to its full potential as its direct value is less visible. A case study was conducted to define which types of non-value adding activities can be identified within information flows and to determine whether decentralized application development can eliminate this digital waste. An internal information flow was modelled, analyzed and optimized by developing customized applications on the Microsoft Power Platform. Based on literature from the field of manufacturing and software development, a framework was developed to categorize digital waste as well as higher order root causes in terms of business strategy and IT infrastructure. While decentralized app development provides the ability to significantly reduce operational digital waste in a simplified manner, it can also enable unnecessary expansion of a common data model and requires application lifecycle management efforts as well as edge security to ensure data compliance and governance. Although limited to one case study, the suggested framework could give insights to organizations that aim to optimize internal workflows by identifying and eliminating digital waste and its root causes. / I en tid där nätverk av sammankopplade enheter expanderar snabbt, är det svårt för organisationer att anpassa sig till den allt mer datoriserade och dynamiska miljön och samtidigt förbli konkurrenskraftiga. Anställda upplever att mycket av deras tid och resurser spenderas på repetitiva, ineffektiva och vardagliga uppgifter. Lean manufacturing har visat sig vara ett välkänt optimeringskoncept, dock har informationshantering och avlägsnande av slöseri inte ännu nått sin fulla potential eftersom dess direkta värde är svårare att se och räkna. En fallstudie genomfördes för att definiera vilka typer av icke-värdeskapande aktiviteter som kan identifieras inom informationsflöden och för att avgöra om decentraliserad applikationsutveckling kan eliminera detta digitala slöseri. Ett internt informationsflöde modellerades, analyserades och optimerades genom att utveckla anpassade applikationer på Microsoft Power Platform. Baserat på litteratur från tillverknings- och mjukvaruutvecklingsområdet utvecklades en ram för att kategorisera digitalt slöseri samt högre grundorsaker när det gäller affärsstrategi och ITinfrastruktur. Medan decentraliserad apputveckling ger möjlighet att avsevärt minska det operativa digitala slöseriet på ett förenklat sätt, så kan det också möjliggöra onödig expansion av en gemensam datamodell och kräver hantering av livscykelanalyser samt kantsäkerhet för att säkerställa datahantering och styrning. Trots begränsad till en fallstudie, så kan det föreslagna ramverket ge insikter till organisationer som syftar till att optimera interna arbetsflöden genom att identifiera och eliminera digitalt slöseri och dess grundläggande orsaker.

The objective of this dissertation is to suggest the structure of new IS in the company, to suit the recent data flows, and simultaneously to satisfy the needs of the user. According to the suggestions and concepts mentioned in the thesis, it should be possible to pre – set a completely functional IS.

The master‘s thesis focuses on the design of mobile application for web portal Hlidani.eu on Android platform. The theoretical part of the thesis analyzes problems and terms concerning mobile applications. The thesis uses selected analytical methods to analyze the current state of web portal Hlidani.eu. Based on these results, the application itself is designed.

<p><em>Tangible social network system is a home-based communication solution specifically designed for elders. Former researches indicate that insufficient communication among elders cause several challenges in their daily activities such as social isolation, loneliness, depression and decreased appetite. In addition, lack of social participation increases the risk of Alzheimer´s (Ligt Enid, 1990). The major cause of these challenges are that elders are increasingly removed from communication technology using emails, text messaging, interact with social network systems and mobile phones due to cognitive and physical difficulties. To overcome this problem, new suggested social network system incorporates photo frame and photo album based interaction which allows instantaneous participation to the social network. By designing the new social network system, I tried to create an easier venue for more active cross-generational communication between elders and younger family members.This paper discusses the early results of the marker based social networking system aiming to propose digital technologies to enhance the social life of older people, who live alone their home. A prototype combining a touch screen, photo frame and a camera are described. It allows the older people to manage their participation to the social network system and get in touch with their loved ones. This paper demonstrates a User Sensitive inclusive Design (USID) process from the generation of user needs to the evaluation prototype. A key theme of tangible social network system shows how usable and emotional design derived from a user inclusive design process can encourage elders to adopt new modern technology. A first evaluation has shown the usability as well as the good acceptance of this system.</em></p> / AGNES

My diploma thesis is focused on a comprehensive analysis of a selected company, its business environment and possible risks associated with the implementation of the proposed change in the supply process using a mobile application. My proposed solution includes a risk reduction method, a complex view of the processes in the application and its graphic design, along with the estimated costs of implementing the change.

The master thesis deals with the development of the tool for risk analysis support in information security. At first we perform a theoretical basis for security development of lifecycle process (SDL). Afterwards the theory of risk analysis based on fault tree analysis is described. Considering this knowledge base system was designed and implemented. Next chapter describes the best practice refer to the typical example of use and presents the potencial using of this tool in practice. Final chapter deals with the possibility of future expansion of this application.
