Job Task Planning and Organizing
  • Lumber graders and other wood processing inspectors and graders follow production schedules set by their foremen. They may help to formulate these schedules by participating in meetings with other staff. Their tasks are dictated by the speed of production line belts or grading tables and the speed of co-workers, such as lathe operators who feed sheets to sections of the line and assistants who tend to the bins where the sheets are fed. Tasks are repetitive and require intense concentration. Work can be interrupted by equipment malfunctions, inspectors needing to provide training or running out of stock. Planning and organizing of job tasks is short-term, focusing primarily on grading high volume loads quickly and reacting to problems. (2)

Decision Making
  • Decide whether substandard pieces of wood can be made acceptable to grade standards if they are sectioned into several smaller pieces. (2)
  • Decide whether to refuse a delivery which does not conform to standards, and what penalties should be imposed for fraudulent deliveries. (2)
  • Make instant decisions on how to grade and trim boards, on how the number and size of defects affect grades and whether to scrap products or sell them to reduce wastage. Grade decisions must fall within a 5 percent error tolerance, and can significantly affect production quality and profit margins. This decision making is at the core of the job with thousands of decisions being made during a shift. (3)
  • Decide whether work priorities set by the supervisors need to be adjusted in view of urgent orders or orders of large volume. (3)
Back to Top

Problem Solving
  • Deal with machine malfunctions such as sorter machine jams. Stop the machine, lock it out and make necessary adjustments or call for service help. (1)
  • The moisture levels are so high in the wood that it has set off moisture alarms. Wait until the wood is dry before grading it. The kiln temperature may be raised in order to dry wood faster. (1)
  • Deadlines are tight. Consider ways to speed production. Adjusting roller bars on the line, changing saws or repositioning wood are ways of increasing production. (2)
Back to Top

Finding Information
  • Call trucking companies to verify shipments. (1)
  • Refer to grading manuals, pocket guides and consult with other graders or supervisors if unsure how products should be graded. (2)
  • Refer to training manuals and charts in textbooks from past training courses. (2)
