By modelling an organizations business processes, it is possible to capture how the organization coordinates the work and resources with the aim of achieving its goals and strategies (Sharp, et al., 2001). Since business processes and goals are intrinsically interdependent, establishing an alignment between the process and the goal domains arises as a natural approach. This thesis reports on a real-life exploratory case study in which we investigated the relationship between the elements of the enterprise (modeled in the ARIS framework) and the goals (modeled in the Tropos framework and modeling language) which are attained by these elements. The case study has been conducted in the Rheumatology Department of a University Hospital in Brazil. In the course of the case study, we have identified the need of splitting this effort into three phases: the elicitation phase (in which goal models and business process models are captured from the organizational domain), the harmonization phase (in which the goal domain is structured for alignment according to the business processes structures that will support it) and the alignment phase (in which the relationships between the goal domain and the elements of the organizational domain are established). In order to investigate the relation between goals and enterprise elements, we propose an ontological account for both architectural domains. We recognize the importance in considering the business process as the means for implementing an enterprises strategy, but we do not exclude the remaining enterprise elements. Furthermore, we are concerned with both the identification of the relationships and with a classification for their nature.

Variações de contextos impõe novos desafios ao desenvolvimento de sistemas seguros, o que inclui a ativação de falhas apenas em contextos específicos de operação. A engenharia de requisitos orientada a objetivos (GORE) explicita o ‘por quê’ dos requisitos de um sistema, isto é, a intencionalidade por trás de objetivos do sistema e os meios de se atingi-los. Um Runtime goal model (RGM) adiciona especificação de comportamento ao modelo de objetivos convencional, enquanto um Contextual goal model (CGM) especifica efeitos de contextos sobre objetivos, meios e métricas de qualidade. Visando uma verificação formal da dependabilidade de um Contextual-Runtime goal model (CRGM), nesse trabalho é proposta uma nova abordagem para a análise de dependabilidade orientada a objetivos baseada na técnica de verificação probabilística de modelos. Em particular, são definidas regras para a transformação de um CRGM para um modelo cadeia de Makov de tempo discreto (DTMC) com o qual se possa verificar a confiabilidade de se satisfazer um ou mais objetivos do sistema. Adicionalmente, para diminuir o esforço de análise e aumentar a usabilidade de nossa proposta, um gerador automatizado de código CRGM para DTMC foi implementado e integrado com sucesso à ferramenta gráfica que dá suporte às fases de modelagem e análise de objetivos da metodologia TROPOS. A verificação contextual de dependabilidade resultante reflete os requisitos no CRGM, que podem representar: o projeto de um sistema, cuja verificação ocorreria em fase de projetos; ou um sistema em execução, cujo comportamento pode ser verificado em tempo de execução como parte de uma análise de auto-adaptação com foco em dependabilidade. / A static and stable operation environment is not a reality for many systems nowadays. Context variations impose many threats to systems safety, including the activation of context specific failures. Goal-oriented requirements engineering (GORE) brings forward the ‘why’ of system requirements, i.e., the intentionality behind system goals and the means to meet then. A runtime goal model adds a behaviour specification layer to a conventional design goal model, and a contextual goal model specifies the context effects over system goals, means and qualitative metrics. In order to formally verify the dependability of a CRGM, we propose a new goal-oriented dependability analysis based on the probabilistic model checking technique. In particular, we define rules for the transformation of a CRGM into a DTMC model that can be verified for the reliability of the fulfilment of one or more system goals. Also, to mitigate the analysis overhead and increase the usability of our proposal, we have successfully implemented and integrated a CRGM to DTMC code generator to the graphical tool that supports the goal modelling and analysis phases of the TROPOS development methodology. The resulting contextual dependability verification reflects the system requirements in a CRGM, which may represent: a system-to-be, whose verification would take place at design-time; or a running system, whose behaviour can be verified at runtime as part of a self-adaptation analysis targeting dependability.

Many organisations are continuously searching for methods which can be used to improve performance. One such method is by means of implementing a performance management programme. This research study addresses the influence that a performance management programme has on the achievement of organisational and individual performance. To achieve this objective a comprehensive literature study was performed to determine the views on performance, and on performance management programmes. The study also included an investigation into the extent to which a performance management programme should be aligned with organisational and individual goals. Questionnaires, developed from the literature study, were distributed amongst randomly selected respondents, in order to determine the extent to which a specific organisation manages performance, in line with the guidelines provided by the literature study. The information obtained from the questionnaires were compared with the guidelines provided by the literature study in order to identify shortcomings in the influence that the performance management programme has on the achievement of organisational and individual goals at the selected organisation. The final step of this study entailed the formulation of recommendations. Three of these recommendations are regarded as critical to ensure the successful improvement of performance by means of a performance management programme: Firstly, it is of utmost importance that training and development, and the necessary resources to achieve objectives is provided. Secondly, feedback forms an integral part of a performance management programme. Those who provide feedback, need to acquire the necessary skills, so as to ensure that both positive and negative feedback is given to employees, which could ultimately enhance performance. Thirdly, the success of a performance management programme resides with both management and employees. Management need to be committed to the programme, and the well-being of their employees. Management also needs to be able to eliminate problems that negatively influence performance. On the other hand, employees need to realise that a performance management programme is not only linked to pay, but also the development of each individual, and the improvement of performance.

Många motivationsteorier existerar vilka försöker beskriva drivkraften bakom våra handlingar. En sådan är goal-setting teorin enligt vilken specifika svåra mål skapar bättre prestationer. Self-efficacy påverkar dessutom influensen av mål eftersom individer med hög self-efficacy tenderar att engagera sig mer kring uppsatta mål. Effekten av mål verkar även bero på nivån av komplexitet i en uppgift. Syftet med studien var därför att vidare undersöka hur goal-setting och self-efficacy tillsammans påverkar prestationer på uppgifter med olika grad av komplexitet. En enkätundersökning med 145 undersökningsdeltagare genomfördes där prestation på två olika uppgifter testades med och utan mål samt relaterades till generell self-efficacy. Resultaten visade dock inga signifikanta skillnader i prestation mellan grupper som blev tilldelade specifika svåra mål och grupper som inte blev tilldelade tydliga mål. Ingen signifikant påverkan av self-efficacy kunde heller påvisas för de olika betingelserna. Resultaten antas främst bero på uppgifternas korta tidsspann, deltagarnas egen förmåga och uppgifternas svårighetsgrad.

As millions of baby boomers approach retirement, they will face one of the most significant and potentially life-altering decisions they’ve ever made – the pursuit of a travel-based retirement lifestyle. When people make such high-stakes decisions it is inevitable that their salient desires are engaged and likely that goal conflicts will arise. An extensive literature has focused on understanding travelers’ motivations, but this research has rarely examined how people cope with the conflicts that are inherent in travel decisions. Retirement provides a perfect natural context to study such decisions. In this study we use netnography – a method of observing online consumer-to-consumer communications – to discern the tensions that arise when aspiring travelers’ goals are in conflict. Furthermore, we investigate how experienced travelers in the online community offer aspiring travelers moral support, advice and referrals that help to resolve these goal conflicts, thus easing decision-making tension and moving the decision-maker closer to the choice of a travel-based lifestyle. The findings offer a better understanding of multiple goal pursuit in retirement travel, where (1) desires serve as superordinate goals that are engaged in travel planning, (2) retiree travelers juggle multiple goals that often result in goal conflicts and (3) the importance of online community in providing advice as proposed solutions to achieve goals and resolve goal conflicts. Lastly, implications and limitations of this study are discussed.
