Sustainability and intelligence are two of the major themes facing us as individuals and organisations in today�s knowledge economy. The first of these themes is the challenge of ensuring economic, social and environmental sustainability in every aspect of our personal, working and organisational lives. This requires us to factor sustainability into our plans, actions and decisions at every level. To do this we need intelligence which, like sustainability, has many potential meanings and applications. At one level it is the ability to apply knowledge, skills and abstract reasoning; to adapt to new and unfamiliar situations; to observe and empathise; and to learn from experience. Traditionally it has been assumed that intelligence was a capability of sentient beings (humans and other animals), but artificial intelligence (AI) is emerging as a significant support or alternative. At another level, intelligence can be considered as the knowledge, information and data that enable us to learn, take action and make decisions. Associated with this, at a project or organisational level are knowledge management (the systematic development and management of knowledge assets) and business intelligence (the use and transformation of raw data into meaningful information and insights) to support strategy, value creation and sustainability. This Unit of Study will focus on aspects of sustainability and intelligence relevant to project leadership. It will begin with an overview of economic, social and environmental sustainability and an examination of how corporate and societal global sustainability goals can be achieved through decision and action in projects, programs and portfolios. With this context, we will then look at how project teams, organisations, and societies build knowledge capabilities to sustain excellence and performance. Project and knowledge management are interconnected through the measures of project outcomes and the use of knowledge assets such as expertise, collaboration, decision-making, policies and procedures. Ultimately, project success is dependent on effective exchange and access to critical knowledge. Such critical knowledge is increasingly being supported by development of business intelligence capability and drawn from effective use and analysis of data including big data to reveal patterns, trends and connections. The Unit will conclude with an overview of business intelligence and data analysis and how it is being used to support projects and organisations.
