- Learning from incidents is important for improving safety. Many companies spend a great deal of time and money on such learning procedures. The objectives of this paper are to present some early results from a project aimed at revealing weaknesses in the procedures for learning from incidents and to discuss improvements in these procedures, especially in chemical process industries. The empirical base comes from a project assessing organizational learning and the effectiveness of the different steps of the learning cycle for safety and studying relations between safety-specific transformational leadership, safety climate, trust, safety-related behavior and learning from incidents. The results point at common weaknesses in the organizational learning, both in the horizontal learning (geographical spread) and in vertical learning (double-loop learning). Furthermore, the effectiveness in the different steps of the learning cycle is low due to insufficient information in incident reports, very shallow analyses of reports, decisions that focus at solving the problem only at the place where the incident took place, late implementations and weak solutions. Strong correlations with learning from incidents were found for all safety climate variables as well as for safety-related behaviors and trust. The relationships were very strong for trust, safety knowledge, safety participation and safety compliance.

- Cost escalation for fighter aircraft is arguably not sustainable. Pushing frontiers oftechnology by incremental improvements of traditional platforms has led to anexponential increase in cost. This paper addresses the process of concept generationwith the purpose to explore how affordability is managed in that process, in order toidentify possible measures to improve the likelihood of generating affordableconcepts. This is done by studying two cases of concept generation of future combatair systems. The concepts generated in these two cases are however not curbing thecost escalation and are, with only one notable exception, based on incrementalinnovation. Nevertheless, the empirical observations offer leads to potentially fostera more innovative and cost conscious concept generation process, indicatingavenues for future research.

- Cost escalation for many complex defence equipment is arguably not sustainable. Customer driven requirements have led to an exponential increase in costs by pushing frontiers of technology to support primarily incremental improvements of traditional equipment concepts. Accordingly, affordability has become a more discussed subject indefence acquisition. This paper addresses the process of generating complex defence equipment concepts. The purpose is to explore how affordability is managed in that process and to identify possible leads to how an unsustainable cost escalation for this type of equipment can be curbed. This is done by studying two cases of concept generation of future combat air equipment systems from a company process perspective. This applied micro perspective on cost escalation showed that none of the concepts generated in these two cases were assessed to curb the cost escalation. Further, the innovation model for the generated concepts, with only one notable exception, was incremental. Nevertheless, the empirical observations from these two cases offer leads on how to potentially foster a more innovative and affordability-oriented concept generation process for future defence equipment, as well as indicating avenues for future research.

Changing Path and Curbing Cost Escalation : Lessons Learnt from the Gripen Case

- Extant theory suggests that paths of development, although identified as being unsustainable, might be difficult to depart from. The aim of this study has therefore been to explore and understand how a path change can be facilitated in a setting of complex product systems. A unique single case of product development that managed to curb an unsustainable intergenerational cost escalation for complex defence equipment has been studied. The study shows a relation between a path change and a challenging opportunity, and also indicates how this relation can be moderated by the company management and the customers. The study provides both theoretical and practical implications, supporting understanding and facilitation of path changes.

Inducing Affordability?: Observations From An Experimental Study Of Concept Generation

- Early preliminary concepts are claimed to have a profound impact on the final product. Since these concepts often are based on intuitive judgements, it is important that these judgements are appropriate for the desired outcome. Intuition is derived from what one brings to mind, and consequently, the access to information is important for making relevant judgements. Therefore, when a departure from a present path of development is sought for, access to new information is likely to be required. Results from an experimental study, addressing affordability and concept generation, indicated that individuals were influenced, by the provision of selective information, to make more cost considerations and even to change approach when generating new concepts. It was further recognized that weak abilities to estimate costs in a lifecycle and capability perspective likely hampered low-cost ambitions. The findings from this study are suggested to contribute to theory on product development, and to support affordability when new products are developed.

Managing affordability in concept development of complex product systems (CoPS)

Tidskriftsartikel (refereegranskat)abstract
- This study originates in a recognised unsustainable cost escalation for complex defence equipment. In order to understand how such cost escalation for complex product systems (CoPS) can be avoided, this study comparatively explores four different industrial sectors - energy, transportation, healthcare and defence - with and without intergenerational increasing costs, represented by four international companies. The results, collected from studying the development of one of each company’s products, reveal some characteristic differences in market factors between those sectors and companies having problems with intergenerational escalating costs and customer affordability, as compared to other sectors and companies. It is suggested that dependent on market characteristics, it might be necessary to actively manage affordability when CoPS are developed. Efforts made by the companies to make products more affordable were identified, and several factors enabling and disabling the development of less costly products without compromising customer needs were explored. Further, the implications of affordability management in a CoPS setting are elaborated on.
