FEL is a project execution model that uses a phased approach to let stakeholders handle risks and commit extra resources at well-defined approved milestones throughout the project life cycle. Front-end loading engineering should be a flexible procedure that benefits project engineers on projects of any size. A correctly implemented FEL program results in more successful projects with improved cost and schedule performance, better risk management, and fewer scope changes.
