Digital Technology
  • Use other computer applications. For example, use computer-controlled machinery to read diagnostic information. (1)
  • Use communications software. For example, forward faxes to head office and post questions on electronic bulletin boards linking dealers across North America. (2)
  • Use a database. For example, access technical information and enter production data. (2)
  • Use word processing. For example, prepare memos. (2)

Oral Communication
  • Listen to instructions called out from the other end of the floor. (1)
  • Interact with suppliers to place orders or to discuss problems with supplies, such as bonding adhesives. (2)
  • Communicate with co-workers to co-ordinate work and to exchange information about procedures and technical problems. (2)
  • Interact with the supervisor to receive work assignments and to troubleshoot assembly and quality problems. (2)
  • Communicate with seasonal employees and helpers to assign tasks, provide on-the-job training and oversee their work. (2)
  • Interact with assemblers to check subassemblies, inspect finished products for proper quality and to discuss quality control problems. (Inspectors) (3)

Scheduling or Budgeting and Accounting
  • Schedule work for assemblers, taking into consideration factors such as the availability of parts and deadlines. (2)
Back to Top

Measurement and Calculation
  • Take measurements to perform such tasks as cutting wire to specific lengths or drilling holes in the correct location. (1)
  • Measure parts, compare to specifications and adjust the fit. (1)
  • Take precise measurements using specialized measurement equipment, such as micrometers and callipers, to ensure that equipment meets the prescribed tolerances. (3)
  • Use formulae to calculate hydraulic pressure when performing custom work on hydraulic pumps or to set the ballast weights on tractors. (4)

Numerical Estimation
  • Estimate by sight how many components will fit in a cabinet to determine how many cabinets will be required. (1)
  • Estimate the length of time required to do a job, considering the time required to complete each step of the assembly. (2)

Job Task Planning and Organizing
  • Most mechanical assemblers and inspectors have some variety in their work activities as they work with different types and models of mechanical products; however, the work may be repetitious. Work priorities and deadlines are usually set by forepersons and supervisors who allocate work at the beginning of each shift. Within this framework, they have considerable scope to plan and organize their job tasks and the choices made in this regard greatly impact efficiency. They co-ordinate their work plans with the work plans of co-workers to schedule access to shared tools and equipment. Inspectors co-ordinate their work plans with assemblers to perform such tasks as checking electrical assemblies and wiring for proper connections. The day's work plan is occasionally disrupted by mechanical and quality problems which must be resolved immediately. (3)

Decision Making
  • Decide whether to fix an ill-fitting part or get a replacement, remaining accountable for discarded parts. (1)
  • Decide when to substitute a more expensive part when the recommended part is not immediately available to meet a deadline. Seek approval from the supervisor for this type of decision. (1)
  • Decide what supplies to buy, in what quantity and from which supplier. For example, decide what gauge of steel to buy based on the kind of trailer a customer wants. The wrong decision would be costly to the company and delay assembly. (2)
  • Decide on the allocation of job assignments, considering factors such as work priorities and a worker's competencies. (3)
  • Decide whether mechanical products adhere to quality control standards. (3)

Problem Solving
  • There is a shortage of parts. If possible, the work may be completed by using substitute parts. (1)
  • A part will not fit after several adjustments were made. Consider various options to modify the part, such as redrilling or grinding it, and test the part at different stages of modification for the proper fit. (2)
  • It is evident that an assembly drawing is incorrect. Determine whether you have the skill and experience to identify and correct the error, consulting with co-workers or the cell leader if other opinions are required. (2)
  • A hoist creeps down instead of remaining stationary. Perform visual inspections and tests to isolate what may be causing the problem, such as leaks of air or oil in the system, before making the appropriate repairs. (3)
  • It is found that a hydraulic pump is getting insufficient pressure. Check the oil and pump components, for example, to isolate the cause of the problem. Diagnosing the root cause of the problem is often more complex than implementing the solution, which may be as simple as removing dirt. (3)

Finding Information
  • Read parts lists and parts catalogues to request materials from the parts depot. (1)
  • Ask questions using an electronic service bulletin board, linking dealers across North America, to seek technical advice or to learn about new products and processes. (2)
  • Refer to multiple manuals to find and synthesize information needed when troubleshooting technical problems. (3)
