  • Coronavirus and related case studies

    We have added two topical case studies to our web site. The first case describes how a simple yet rapid vulnerability analysis helped the management team of a university residential college to develop a comprehensive protection strategy when confronted by an evolving coronavirus threat. The second case describes work we conducted some years ago to develop a suite of spatial models of epidemic and pandemic influenza, aimed at helping policy makers explore a range of scenarios and interventions for the control of an outbreak.

  • Developing a scientific instrument

    This case outlines qualitative and quantitative analyses of the uncertainty associated with a high-profile project to develop a scientific instrument. The case demonstrates the value of qualitative and quantitative analyses when they are conducted at an early phase of a project.

  • Range analysis – summary of good practice

    This tutorial is drawn from Broadleaf’s long experience with project range analysis, also referred to as quantitative risk analysis or probabilistic risk analysis. It describes some key lessons about project range analysis, and what constitutes good practice. The material covers the analysis of both costs and schedules; the same principles apply to both.

  • Providing water for a mine

    There has been discussion recently about the importance of water in mining activities, including the impact of mining on water sources, the associated effects on approvals for new mines, and the implications for mine water management. In this case study, a preliminary hazard and operability (HAZOP) study of a mine expansion project identified potentially major risks associated with a large water pipeline near a village. A simple scenario-based risk assessment, conducted quickly by a small team, generated a range of improvement options for pipeline design and construction. Simple approaches can generate excellent results when used appropriately. It is important not to short-cut the risk management process by eliminating any of the steps, but the steps themselves can be tailored according to the project’s scope and need.

  • Climate change in a rural shire

    There has been a lot of discussion about climate change recently, so we've prepared a relevant case study from our archives. It outlines a risk assessment that examined the effects of climate change on a rural shire in Australia. The case demonstrates the use of climate scenarios, and risk assessment over short-term, medium-term and long-term time horizons. It uses an extended risk analysis template as a continuing record of important supporting information for justifying treatment responses, some of which may relate to risks with impacts only in the far distant future but that require action in the short term to avert problems or to build resilience.

  • Upgrading refineries for clean fuels

    This case illustrates the value of qualitative and quantitative risk analyses in refinery upgrades that had to be completed within the strict time constraints imposed by tight shutdown windows. Schedule impacts drove the qualitative assessment, and a quantitative analysis of uncertainty associated with the schedule was completed. Several forms of sensitivity analysis were used to highlight where additional project effort might be worthwhile.

  • Tailoring risk assessment for a port expansion project

    This case describes a simple project risk assessment undertaken to initiate formal risk management on a large expansion program for a port that handled bulk commodities for export. It demonstrates the value of tailoring the risk assessment for the circumstances. In this case, a modified pre-mortem process was used for risk identification, and the corporate scales for operational risk analysis were adjusted to better suit the project.

  • Review of shift resourcing

    This case concerns the effects of reducing the number of personnel allocated to each shift at three industrial plants. The reduction was proposed in response to cost savings imposed on the wider business by the need to remain competitive. Detailed preparation and close stakeholder involvement were important factors in developing useful outcomes.

  • Concept-stage assessment of new technology in locomotives

    A rail operator was investigating options for improved locomotive fuel management, one of which included programmable logic controllers (PLCs). While the proposed PLC technology had a widely installed industrial base, none had been fitted to the company’s locomotives at the time of this study and local industry knowledge of applications like this was limited. We conducted a risk assessment of the new technology at an early stage of the design, ensuring stakeholders’ concerns were captured and acceptance for the technology was gained before the company made a major investment in production.

  • Tutorial on learning lessons and root cause analysis

    Organisations use root cause analysis to learn lessons from both successes and failures, and then to develop plans that will improve performance. Broadleaf's new tutorial describes consistent and systematic methods that can be adopted for learning lessons and generating improvements. It describes two methods: fishbone analysis, and cause and effect analysis.
