Management of risks in information technology projects

Abstract: Information technology (IT) projects are renowned for their high failure rate. Risk management is an essential process for the successful delivery of IT projects. In‐depth interviews with IT professionals from leading firms in Western Australia were undertaken to determine how IT risks were managed in their projects. The respondents ranked 27 IT risks in terms of likelihood and consequences to identify the most important risks. The top five risks, in order, were: personnel shortfalls; unreasonable project schedule and budget; unrealistic expectations; incomplete requirements; and diminished window of opportunity due to late delivery of software. The respondents overwhelmingly applied the treatment strategy of risk reduction to manage these risks. Furthermore, these strategies were primarily project management processes, rather than technical processes. This demonstrates that project management is a risk management strategy. Scope, quality management, and human resource management were solutions applied to several risks. In particular, managing stakeholders’ expectations is a specific risk treatment that helps to manage several key IT risks.

Exercise and Parkinson's: benefits for cognition and quality of life

Abstract: Cruise KE, Bucks RS, Loftus AM, Newton RU, Pegoraro R, Thomas MG. Exercise and Parkinson’s: benefits for cognition and quality of life. Acta Neurol Scand: 2011: 123: 13–19. © 2010 The Authors Journal compilation © 2010 Blackwell Munksgaard. Objectives – The benefits of physical exercise for psychological aspects of quality of life (QoL) are well established in normally ageing adults, yet potential benefits for people with Parkinson’s disease (PD) have received limited attention. This study evaluated the benefits of exercise for cognitive functioning, mood and disease-specific QoL for people with PD. Methods – Twenty-eight individuals with PD were allocated to an exercise intervention program (EIP, n = 15) or control group (n = 13). The EIP group undertook a programme of progressive anabolic and aerobic exercise twice weekly for 12 weeks. The control group maintained their usual lifestyle. Results – Exercise was shown to have selective benefits for cognitive functioning by improving frontal lobe based executive function. No significant effects were demonstrated for mood or disease-specific QoL. Conclusions – These results are consistent with previous research demonstrating selective benefits of exercise for executive function among normal ageing adults and PD.

A model to develop effective virtual teams

Abstract: A review of the literature shows the factors that impact on the effectiveness of virtual teams are still ambiguous. To address this problem we developed a research design that included a meta-analysis of the literature, a field experiment and survey. The meta-analysis identified factors which impact on the effectiveness of virtual teams which were then validated by a field experiment and survey. The results of the study indicate that social dimensional factors need to be considered early on in the virtual team creation process and are critical to the effectiveness of the team. Communication is a tool that directly influences the social dimensions of the team and in addition the performance of the team has a positive impact on satisfaction with the virtual team. A major contribution of the paper is an integrated model of factors that contribute to virtual team effectiveness.

Mechanical Behavior of Porous Commercially Pure Ti And Ti–TiB Composite Materials Manufactured By Selective Laser Melting

Abstract: Commercially pure titanium (CP-Ti) and Ti–TiB composite parts with three different porosity levels (i.e. 10%, 17% and 37%) were produced by selective laser melting (SLM). Scanning electron microscopy (SEM) investigations show that martensitic (α′) microstructure exists in SLM-processed CP-Ti parts, whilst SLM-processed Ti–TiB composites present needle-shape TiB particles distributed in α-Ti matrix. Mechanical properties of these porous samples decrease with porosity level increasing. The yield strength and elastic modulus of porous CP-Ti parts range 113–350 MPa and 13–68 GPa respectively, which are much lower than those for porous Ti–TiB counterparts (234–767 MPa and 25–84 GPa respectively) mainly due to the strengthening effect induced by TiB particles in Ti–TiB samples. Compression stress–strain curves of 37% porous CP-Ti parts show a typical three-stage behavior of ductile porous metals. Also, the elastic moduli of both 37% porous CP-Ti and Ti–TiB samples are similar to that of human bone. SEM investigations of the porous CP-Ti samples after compression testing show that no crack presents until 50% compressive strain and most of deformation is absorbed by porous areas. In contrast, μ-CT investigations indicate that all porous Ti–TiB samples fail at early stages of compression testing due to cracks resulting from insufficient ductility of struts of porous areas, because they are not able to accommodate high strains of the deformation at high strengths.
