Abstract Software modularity and partial qualification capabilities are key enablers to produce cost efficient software in highly regulated domains. The modular concept (called spaceAPPS) described in this paper has been developed in the frame of the OPS-SAT project aiming at missions where flexibility is one of the success factors. spaceAPPS implements a novel software architecture for satellites inspired by the Apps concept of modern smartphones. In the European space domain the operation of a satellite is based on a set of 18 services. Accordingly, in spaceApps these services are mapped to individual Apps. This is not a one-to-one mapping which means that one App implements one or more services. During OPS-SAT ground testing it was demonstrated that functionality could be easily added through a new App or updated through replacing an existing App. Also during OPS-SAT ground testing it could be shown that a failing UserApp did not impact the basic apps to operate the satellite. Thus, it is possible to run applications of different criticality on the same platform. With operating systems supporting time and space separation the risk of failure propagation can be further reduced. The implementation of a partial validation approach, i. e. testing of third-party Apps in a representative environment and not running the validation on the target platform is feasible but was not demonstrated.

Cognitive interviewing is a common method used to evaluate survey questions. This study compares traditional cognitive interviewing methods with crowdsourcing, or “tapping into the collective intelligence of the public to complete a task.” Crowdsourcing may provide researchers with access to a diverse pool of potential participants in a very timely and cost-efficient way. Exploratory work found that crowdsourcing participants, with self-administered data collection, may be a viable alternative, or addition, to traditional pretesting methods. Using three crowdsourcing designs (TryMyUI, Amazon Mechanical Turk, and Facebook), we compared the participant characteristics, costs, and quantity and quality of data with traditional laboratory-based cognitive interviews. Results suggest that crowdsourcing and self-administered protocols may be a viable way to collect survey pretesting information, as participants were able to complete the tasks and provide useful information; however, complex tasks may require the skills of an interviewer to administer unscripted probes.

To improve the productivity and quality of software development, a software synthesis shell called SOFTEXSHELL has been developed. SOFTEXSHELL is a tool kit with a transformation system based on a term rewriting system, a language DSL/C++ for defining transformation rules as well as a specification language for a specific software model, and a rule verification system which supports development of correct transformation rules. The system is designed to provide an environment which enables a broad range of software engineers to construct software synthesis systems for their domains. To evaluate how effectively SOFTEXSHELL does this, a software synthesis system for switching scenario software was developed by two switching software specialists without prior software synthesis experience. After a four-month prototype development period, a practical software synthesis system for switching service software was developed in eight months. The developed software synthesis system, SOFTEX/EX, has been utilized for developing six switching systems. Generated programs, including 272,000 steps in total, have been in daily operation. Based on the development process and developed system results, we conclude that SOFTEXSHELL enables software engineers, without prior software synthesis experience, to develop useful and efficient software synthesis systems.
