What is this? This ZIP file contains the replication kit for the paper _"Tools for Monitoring Software Quality in Information Systems Development and Maintenance: Five Key Challenges and a Design Proposal"_. The replication kit consists of three components. After unzipping, these are: * The document [`tech_report.pdf`](./tech_report.pdf) contains a more thorough description of the six software quality assessment tools (SWQAT) that are used in the comparative experiment. Furthermore, it contains detailed descriptions of how each SWQAT assesses software quality and in which way assessment results are aggregated and presented.* The directory [`data_collection_protocol`](./data_collection_protocol) contains all the collected data from running the six SWQATs. Per SWQAT and per experiment system, screenshots and other reports that could be exported from SWQATs are contained.* The directory [`experiment_vms`](./experiment_vms) contains scripts and code that instantiates local virtual machines for those cases in which SWQATs do not run completely in the cloud, see [`README.md`](./experiment_vms/README.md).
