Gemba Walks are often done in a layered manner. At the lowest layer, the Department Manager does a daily walk, and an hourly associate presents the data. At these daily walks, it is common for the local maintenance mechanics, engineers, and QC technicians to participate.
LIDAR is similar to the radar commonly used to track everything from airplanes in flight to thunderstorms. But instead of bouncing radio waves off its target, LIDAR uses short pulses of laser light. Some of that light reflects off of tiny particles in the atmosphere and back to a telescope aligned with the laser.
Point cloud of the Grand Coulee Dam symbolized by LAS class code. Source lidar made available by the National Oceanic and Atmospheric Administration (NOAA) Coastal Services Center. The use of lidar has exploded in recent years, and for good reason. The technology can produce higher-quality results than traditional photogrammetric techniques for lower cost. This is accomplished, to a large degree, by the automated collection of measurements that are sampled very densely.
