At what percentage of design development do formal reviews typically begin?

Formal reviews in the design development phase of a project are essential for ensuring that the project stays on track and meets all necessary specifications and requirements. The percentage intervals at which these reviews occur are typically established based on the complexity and phase of the project.

In this case, beginning formal reviews at 50% and 80% completion allows for a structured approach to project assessment. At 50%, the design has typically progressed to a stage where critical decisions regarding materials, layout, and compliance can be thoroughly evaluated. This review serves as a checkpoint to address any issues early in the process so that adjustments can be made before the project moves into later phases.

At 80%, the design is nearly complete, and this review ensures that everything aligns with the project objectives and stakeholder expectations. It allows for final refinements and ensures all systems have been carefully integrated before moving to implementation. This structure helps to minimize risks and promotes successful project outcomes, making the intervals of 50% and 80% ideal for conducting formal reviews in the design development process.
