This chapter provides the concepts of stakeholders and self-assessment. These are two key concepts and components in the pursuit of project and corporate quality and improvement. The chapter highlights concepts and practices relating to stakeholders, key performance indicators (KPIs) and benchmarking. KPIs also provide useful tools for engaging in self assessment activities by enabling the measuring and analysing of the company and/or project, in order to obtain an improved level of performance. Stakeholder theory relates to project and corporate organisational management and business ethics and it addresses both morals and values in managing a construction related enterprise. Stakeholder mapping is an essential activity for construction companies to engage in. The purpose of the KPIs is to enable measurement of project and organisational performance throughout the construction industry. The productivity indicator sets out to establish how much turnover each full time employee generates for the employing organisation.
