Direct Observation (DO) is a powerful Lean Construction technique used to evaluate real-time processes on construction sites. This structured method involves watching activities unfold in their natural environment—without interference—to gather accurate, actionable insights that drive process improvement and workflow optimization.
It’s all about making the workflow unobstructed and maximizing value on-site.
In the context of Lean Construction, Direct Observations guide teams through a systematic improvement journey.
At Lean Touch Solutions, we train teams to conduct Overt, Structured Direct Observations, which produce standardized, quantitative data on current workflows.
This method allows for the collection of reliable, real-time insights without altering the environment—providing a clear picture of how resources, time, and labour are being utilized on site.
The core aim of Direct Observations is to identify and eliminate the 8 wastes (defects, overproduction, waiting, non-utilized talent, transportation, inventory, motion, and overprocessing) that hinder performance on construction projects. Through ongoing observation and analysis, project teams can implement targeted improvements that enhance flow, safety, quality, and cost-efficiency.
