A group of direct production workers that do or share responsibility for similar work, drawing on the same skills and techniques. The ratio of the output produced to the resources used in its production. Request delivery of prerequisite information at or before the time you will be ready to process that information. Either the process is ready prior to requesting delivery or plan reliability is sufficiently high that work plans can be used to predict readiness. Reasons can also be sought for failing to advance scheduled tasks from master schedule to lookahead schedule or from one week to the next within the lookahead schedule.
Resources have production capacities as well as costs.
Consequently, materials and information are not resources, but rather what resources act on or process. The purpose of shielding is the make production units less subject to uncertainty and variation, thereby providing them with greater opportunity to be reliable. But, I forgot, it's Ruben and Tim. I'd better give them an extra day. We always check if we have or can get necessary information from others, if the directives are clear, etc.
