The Planning Lock Process

1. The Planning Lock Process Richard D Smith

2. Introduction into the Lock Process • The planning process within the Railway Environment has been developed over many years, it has recently been improved to include the DWWP process. • The DWWP process, depending on how its implemented is often seen as an additional activity in the planning process. • The Lock Process has been developed to link the normal Railway planning activities with the DWWP process and with the Last Planner process. • It’s a simple system that defines when certain deliverables are required and more importantly what needs to be updated and re-briefed should any changes occur.
