“…Development and validation of the System Dynamics simulation model are ongoing in order to provide support to ITO decision making (Bezerra and Medeiros, 2013;Bezerra et al, 2014). The model has been in use at the Finance and Revenue Agency of Alagoas State, Brazil (SEFAZ-AL) which is for tax collection and financial control of the state administration.…”

“…The model to support decision making and ITO capabilities management proposed in (Bezerra et al, 2014) captures the dynamics of interaction between the ITO contract monitoring capability of contracting organizations and the service delivery capability of supplier organizations. Here we expand on this ITO decision support model and apply it to assess risks in the ITO contract monitoring process, enabling the model to support risk-based decisions.…”

Abstract:IT Outsourcing (ITO) is the practice to delegate organizational IT functions to a third party. However, this practice introduces important risks for customer organizations. We have developed a system dynamics simulation model to support ITO decision making that considers a dynamic and integrated view of capabilities management and benefits management. Two IT capabilities are modelled: Contract Monitoring (on the customer's side) and Service Delivery (on the supplier's side). In this paper the proposed model is used to assess the risks presented by a deficit in these capabilities. The results of our experiments indicate that the lack of contract monitoring capability in ITO contracting organizations directly impacts on service conclusion time and influences the cost of contract management, which is an important risk factor related to exceeding the ITO budget. It was also found that low levels of service delivery capability in the supplier most significantly impact the cost of rework and the number of penalties. These factors influence the profitability of the supplier and may induce it to abandon the contract prematurely.

O desenvolvimento de software consiste em um processo complexo, com inúmeras abordagens, que sugerem propostas de gerenciamento em fases bem definidas, visando uma produção que garanta aos produtos a qualidade desejada por seus clientes. Com base nas várias opções de tecnologia existentes e na crescente demanda em diferentes áreas das sociedades, é essencial que as empresas adotem modelos que permitam avaliar o processo de desenvolvimento e produção de software. Este trabalho apresenta um modelo para avaliar a qualidade de software dos cenários de negócios das organizações, com base na dinâmica dos sistemas. O modelo permite simulações de cenários, avaliando o percentual da capacidade de desenvolvimento de software, contribuindo para a melhoria dos processos de gerenciamento. Durante a fase de validação da pesquisa, foi realizado um estudo de caso em três empresas, onde os resultados obtidos foram promissores em termos de preferência, utilidade e eficácia.

“…Organizations use their capabilities strategically to improve their "abilities" to another level of efficient and effective.

Background and purpose: This research aims to investigate which benefits one may expect using Maturity Models in Configuration Management (CM) domain. CM is a support process that helps organizations have better management of their infrastructure. Its importance, in the Information Technology (IT) domain, has increased in recent years, despite this process not being technologically new, and the fact that many organizations implement this process in a haphazard way, which results in it not producing the benefits that it should produce. With the intention of assessing and improving the organizations’ IT processes practices and capabilities, MMs have been developed and implemented. However, the application of MM in the CM domain is yet to be explored.Design/Methodology/Approach: Two Systematic Literature Reviews (SLRs) and a Critical Analysis were performed. In sum, 80 scientific articles of the most rated conferences and scientific journals were analyzed and conclusions were drawn.Results: This research concludes that despite the CM process being badly implemented, using a MM this process could decrease operational costs and increase the quality management of the infrastructure.Conclusion: However, no MM has been developed so far for the CM process practices. This MM would be a viable support tool for the IT organizations providers since this would help organizations have a mature CM process and better control of their IT infrastructure. Therefore, the existence of a MM for the CM domain would be a welcome advancement that should be developed in the future.
