The Last Planner methodology developed by the Lean Construction Institute is a production control tool which has possible benefits for improving planning in the UK construction industry. Its application has been considered in countries outside the UK but there is scope for considering whether it is a practical tool for use in UK construction projects. The application of the methodology to a UK construction project was studied with a view to establishing the value of the tool and the possible barriers to its implementation. After training by the writers the method was developed for use on a project by the project team and applied to the main activities. The writers observed the process and interviewed the participants. The methodology had some success in terms of improving structure and discipline in planning but there were structural and cultural barriers identified which need to be addressed before it can be fully successful
