    Operational software maturity: An aerospace industry analysis
    (World Academy of Science, Engineering and Technology, 2017-09-19) González Muñoz, Raúl; Shehab, Essam; Weinitzke, Martin; Fowler, Chris; Baguley, Paul
    Software applications have become crucial to the aerospace industry, providing a wide range of functionalities and capabilities used during the design, manufacturing and support of aircraft. However, as this criticality increases, so too does the risk for business operations when facing a software failure. Hence, there is a need for new methodologies to be developed to support aerospace companies in effectively managing their software portfolios, avoiding the hazards of business disruption and additional costs. This paper aims to provide a definition of operational software maturity, and how this can be used to assess software operational behaviour, as well as a view on the different aspects that drive software maturity within the aerospace industry. The key research question addressed is, how can operational software maturity monitoring assist the aerospace industry in effectively managing large software portfolios? This question has been addressed by conducting an in depth review of current literature, by working closely with aerospace professionals and by running an industry case study within a major aircraft manufacturer. The results are a software maturity model composed of a set of drivers and a prototype tool used for the testing and validation of the research findings. By utilising these methodologies to assess the operational maturity of software applications in aerospace, benefits in maintenance activities and operations disruption avoidance have been observed, supporting business cases for system improvement.

    Software obsolescence drivers in aerospace: An industry analysis
    (World Academy of Science, Engineering and Technology, 2017-09-19) González Muñoz, Raúl; Shehab, Essam; Weinitzke, Martin; Fowler, Chris; Baguley, Paul
    Software applications have become crucial for the aerospace industry, providing a wide range of functionalities and capabilities. However, due to the considerable time difference between aircraft and software life cycles, obsolescence has turned into a major challenge for industry in last decades. This paper aims to provide a view on the different causes of software obsolescence within aerospace industry, as well as a perception on the importance of each of them. The key research question addressed is what drives software obsolescence in the aerospace industry, managing large software application portfolios. This question has been addressed by conducting firstly an in depth review of current literature and secondly by arranging an industry workshop with professionals from aerospace and consulting companies. The result is a set of drivers of software obsolescence, distributed among three different environments and several domains. By incorporating monitoring methodologies to assess those software obsolescence drivers, benefits in maintenance efforts and operations disruption avoidance are expected.

    Towards software performance monitoring: an approach for the aerospace industry
    (Elsevier, 2015-10-27) González Muñoz, Raúl; Shehab, Essam; Weinitzke, Martin; Bence, Rachel; Fowler, Chris; Baguley, Paul
    Software applications are becoming one of the most valuable assets for companies, providing critical capabilities and functionalities to perform a wide range of operations in the industry. This paper aims to provide a view on software application portfolio monitoring and its integration into business intelligence systems for aerospace manufacturing companies. The key research question addressed is how critical software has become for aerospace industry and how software applications could be monitored. This question has been addressed by conducting an in depth review of current literature and by interviewing professionals from different aerospace companies. The results are a set of key findings regarding software impact in aerospace industry, and a monitoring proposal based in a traditional business intelligence architecture. By incorporating condition monitoring methodologies into the software application portfolio of the enterprise, benefits in maintenance budget allocation and risk avoidance are expected, thanks to a more precise and agile way of processing business data. Additional savings should be possible through further application portfolio optimisation.
