This thesis investigates the concept of citizen developers, in which employees in an organisation take on the role of developers and create software using low-code tools. The primary focus of this report is to examine the necessary steps an organisation must take when introducing citizen developers, particularly regarding solution maintenance. The purpose, therefore, is to establish a foundation for utilising the concept of citizen developers in the workplace, bridging the gap between users and developers. Furthermore, this study aims to explore the organisational structure required to incorporate citizen developers and identify the advantages and drawbacks associated with an organisational structure tailored for citizen developers. Citizen developers possess distinct roles and responsibilities within an organisation, making them experts in their respective fields. This expertise renders citizen developers a valuable resource, as they develop solutions to enhance their own work efficiency and effectiveness. A case company has been selected for this study, and interviews have been conducted with multiple employees from the organisation. Through analysis of these interviews and a comprehensive literature review, a governance model has been developed. The governance model delineates the level of responsibility citizen developers should assume, and an evaluation of the model also uncovers potential advantages and drawbacks of introducing citizen developers within an organisation. Ultimately, this thesis aims to contribute to research on the subject of citizen developers, with particular emphasis on solution maintenance.

Low-code is a modern approach to software development and has grown rapidly in recent years. By hiding complexity behind layers of abstraction, it allows inexperienced developers to create complex applications in a shorter amount of time. This thesis sets out to evaluate the current state of low-code as well as a few of the available low-code development platforms and how well their finished applications perform. A simple order management system was implemented in three low-code development platforms, Mendix, OutSystems, and Airtable, in order to gain experience in all of them. The platforms were then evaluated with respect to user experience and performance. The created applications load time and memory usage were measured in three different tests. It was found that there are plenty of low-code platforms that exist for different purposes, and that they all have their own learning curve depending on how flexible they aim to be. The performance of their respectively created applications is also similar to each other, with the only major differences being by design. / Low-code är en modern metod för mjukvaruutveckling och har vuxit snabbt under de senaste åren. Genom att dölja komplexitet bakom lager av abstraktion, kan oerfarna utvecklare producera komplexa applikationer på kort tid. Detta examensarbetet utvärderar den aktuella statusen för low-code, samt några av de tillgängliga low-code plattformarna och hur deras skapade applikationer presterar. Ett enkelt orderhanteringssystem implementerades på tre stycken low-code plattformar, Mendix, OutSystems och Airtable för att få olika erfarenheter. Plattformarna utvärderades sedan med avseende på användarupplevelse och prestanda. De skapade applikationernas laddningstid och minnesanvändning mättes i tre olika tester och utvärderades. Det visade sig att det finns flertalet low-code plattformar för olika ändamål. Plattformarna har olika inlärningskurva beroende på hur flexibla de är. Prestandan som uppmättes på vardera plattform när applikationen hade utvecklats visade sig vara väldigt likt sinsemellan. Den största skillnaden plattformarna emellan visade sig vara designvalen.

The act of people collecting their health data through health apps on their smartphones is becoming increasingly popular. Still, it is difficult for healthcare providers to use this patient-generated health data since health apps cannot easily share its data with the health care providers’ Electronic Health Records (EHR). Simultaneously, it is becoming increasingly popular to use low-code platforms for software development. This thesis explored using low-code platforms to create applications intended to collect patient-generated health data and send it to EHRs by creating a web application prototype with the low-code platforms Mendix and Better EHR Studio. During the web application prototype development, the developer conducted a diary to capture their impressions of Mendix to show how a developer experiences developing in a low-code platform compared to traditional programming. The result shows that it is impractical to create applications intended to collect patient-generated health data with the two low-code platforms chosen. The analysis of the conducted diary showed that using a low-code platform is straightforward but also challenging for an experienced software developer.
