Exploring the Sources of Waste in Kanban Software Development Projects

The application of agile software methods and more recently the integration of Lean practices contribute to the trend of continuous improvement in the software industry. One such area warranting proper empirical evidence is a project’s operational efficiency when using the Kanban method. This short paper takes a new angle and explores waste in the Kanban-driven software development project context. A preliminary research model is presented for helping the consequent replication of the study. The results from the empirical analysis suggest Kanban can be an effective method in visualizing and organizing the current work, but does not prevent waste from creeping in, although the overall project outcome may be successful.

The set-up of a software engineering research infrastructure of the 2010s

The Software Factory of today is not intellectually following the earlier undertakings with the same name stemming back in 1980s in Japan or in the US, but represents the software development of the 2010s.

Attaining High-performing Software Teams with Agile and Lean Practices: An Empirical Case Study

The main results indicate that self-organization as supported by certain Agile and Lean practices helps teams in achieving higher performance.

Performance Alignment Work: How software developers experience the continuous adaptation of team performance in Lean and Agile environments

This paper aims to understand how software developers experience the continuous adaptation of performance in a modern, highly volatile environment using Lean and Agile software development methodology and generates a grounded theory, Performance Alignment Work, showing howSoftware developers experience performance.

Exploring Virtual Reality as an Integrated Development Environment for Cyber-Physical Systems

Cyber Physical Systems (CPS) development approaches tend to start from the physical (hardware) perspective, and the software is the final element in the process. However, this approach is unfit for the more software-intensive world that is increasingly iterative, connected, and constantly online. Many constraints prevent the application of iterative, incremental, and agile development methodologies, which now are the norm for many other fields of software. Time-consuming system validation can only start when both hardware and software components are ready, which implies that the software delivery and quality is almost always the final bottleneck in the CPS development and integration. Also organizational issues raise concerns - CPS development teams are nowadays often geographically distributed, which can result in delays in the process, shortcomings, and even mistakes. In this paper, we propose using our envisioned open-source Virtual Reality-based Integrated software Development Environment (VRIDE) for developing the next generation, increasingly software-intensive CPSs in efficient ways.

Towards a Secure DevOps Approach for Cyber-Physical Systems: An Industrial Perspective

The study shows that, because security is a cross-cutting property in complex CPSs, its proficient management requires system-wide competencies and capabilities across the CPSs development and operation.
