In the construction process, productivity is best understood by focusing on labour productivity, and measuring the volume or quantity of output per person per day. Productivity is by definition a "comparative" concept, generally discussed in the context of comparing the productivity of a person or group with another person or group, or alternatively by measuring the relative productivity of the same group over time or in different work environments. There are 6 key factors which influence construction productivity 1. The skills, ability and motivation of the workforce; key issues relate to the selection and training of labour and craft, providing them with clear output targets, measuring and providing feedback on productivity. Direct communication, demonstrating respect and encouraging open communication and collaboration between trades are key issues for our site management and senior management alike. Selecting, training and supporting our supervisors is also key.2. The organisation of the production process; A lean process requires efficient logistics and strong collaboration between trades. Good logistics will reduce the key waste areas of excessive transport, poor inventory management, inefficient personnel movement, and waiting. 3. Non-labour resources; The appropriate implementation of non-labour resources is a further key factor in maximising labour productivity ­ resources range from mechanical handling and access equipment to innovative labour-saving devices, and the use of digital technology.4. The "working environment" as an influence on productivity; This reflects the softer issues of providing a fair and just workplace, where mutual respect and openness are clearly demonstrated. The key is the motivation and productivity that is engendered by a culture where each person feels that their contribution is recognised and their opinion respected.5. External Factors; Key examples are the uniqueness of the project itself, the extent of change or re-work which may occur, and the impact of external suppliers. Key to limiting the negative impact on productivity is the development of strong interpersonal relationships across all levels of an organisation between your organisation, your customer and your suppliers. 6. Offsite assembly; "Manufacturing" in the context of this discussion can be loosely defined as the repetitive making, fabrication and possibly the assembly of components. Typically, the process is automated to the greatest extent possible, and takes place in an unchanging environment. Materials move through work areas, workers remain static. The construction P
