Data Analysis
  • Track data for many performance and maintenance parameters using maintenance tracking programs. Track the number of failures, mean time between failures, labour and material costs that were required to maintain equipment over specified time periods. Use these analyses to determine if equipment operation can be improved to reduce the long-term costs. For example, analyze used-oil analysis chemical reports to find out how much machines are wearing and to predict when bearings need to be replaced or gear boxes overhauled. (3)
  • Identify quality parameters, set up data gathering systems, collect and analyze data. For example, monitor lead levels in drinking water following water pipe reconditioning. Collect samples at regular intervals to ensure that lead levels meet acceptable standards and are declining as the system ages. (3)
  • Monitor productivity data of people and machines. For example, track work productivity by monitoring the number of change orders, source control documents, waivers, work instructions and written reports created and issue weighted outputs that recognize the relative difficulty of tasks to develop monthly performance benchmarking data for management and clients. Calculate production rates of robots by averaging their productivity over a number of trials and compare them to the desired levels of productivity of the assembly line. (3)
  • Collect data and develop statistics to describe equipment and system functionality. For example, conduct reliability studies during equipment testing to establish how it performs under various controlled conditions. (4)

Numerical Estimation
  • Estimate the life of machines and equipment. For example, estimate the length of time until machine failures. Consider your knowledge, experience and the analysis of monitoring data to predict the time until failures occur. Clients depend on mechanical engineers to make accurate predictions so that they can take measures to prevent unnecessary and costly plant shutdowns. (3)
  • Estimate durations of development, fabrication, construction and repair tasks. For example, estimate project completion times by considering how well projects have adhered to planned timelines, and the past and future utilization of personnel and materials. Estimate the time required to repair system malfunctions based on clients' descriptions of the problems and the mechanical engineers' experience with similar problems. Accurate estimates are essential for business success and satisfied clients. (4)
  • Estimate costs for mechanical design and construction projects. Consider previous experience with similar jobs. Making accurate estimates is important for mechanical engineers to be able to effectively plan and manage budgets. Inaccurate estimating invariably leads to client dissatisfaction and financial loss for engineering firms. (4)

Job Task Planning and Organizing
  • Mechanical engineers are autonomous and have flexibility to plan their work schedules within frameworks established by their managers. They determine how to organize their work to meet deliverables and timelines of team-based projects. They may need to coordinate and integrate job tasks with other engineers and technical staff. Mechanical engineers often have to reshuffle their schedules to meet client' requests and deal with problems caused by mechanical failures. Mechanical engineers may contribute to long-term and strategic planning for their organizations. They frequently assume project management roles for large projects and plan, assign and coordinate work of co-workers, contractors and vendors. They plan jobs, decide what tasks need to be done, draw up work schedules, and may be responsible for overseeing others' work, providing training and evaluating employees' work performance. (4)
Back to Top

Decision Making
  • Decide which products to purchase and contractors to select. For example, review catalogues to determine if the parts are standard or must be customized and consider costs, volume discounts, delivery times and past experience with product vendors. When selecting contractors consider factors such as work quality, safety records, reputation and ability to deliver on time. If two bids are technically equal, select the lowest bid. (2)
  • Decide which measuring tools and methods to use. For example, decide where to place sensors within machines to get the best measurements when conducting vibration analysis. Consider previous experience, machine layouts, the horizontal or vertical orientation of machines and the shapes of bearings to determine the sensor placements. (2)
  • Decide which materials and equipment to use for engineering projects. Take into account client specifications, industry norms and cost. For example, decide the most appropriate steam flow meters to use by considering available technology, the level of precision needed, availability and costs. (3)
  • Decide which clients have priority when multiple clients are experiencing technical difficulties simultaneously. Consider the types of services required, the time of the calls and the production losses and costs for the clients. For example, one robot out of operation in a car assembly plant can shut down the entire production and may cost ten thousand dollars per hour to the client. (3)
  • Decide the appropriate codes and standards to apply when completing client projects. Use technical knowledge and experience to select the most appropriate codes such as the American Society of Mechanical Engineering Codes and the International Organization for Standardization 9001 standards. (3)

Problem Solving
  • Deal with team conflicts. Meet with the individuals involved, reinforce the fact they are on the same team and discuss options for solving the conflicts that maintain quality and safety. (2)
  • Engineering plans cannot be implemented due to unexpected financial or physical barriers. For example, a mechanical engineer may find that beams are blocking locations where pipes should pass. The mechanical engineer consults a civil engineer to find out if it is possible to move the beams and reviews engineering plans to identify alternative ways to pass the pipes. (2)
  • There are cost overruns in mechanical engineering projects. Consult with team members to review in detail why the costs are higher than expected. Brainstorm to identify less expensive methods and materials that meet the clients' specifications and timelines. (3)
  • Completed jobs do not meet safety and regulatory standards. For example, after school pipes and fittings are replaced, a mechanical engineer may find that lead levels are unacceptable. The engineer convenes a team to brainstorm and identify the sources of lead contamination. The engineer implements measures to deal with the high lead levels and communicates these plans to clients. Once the lead contamination is gone the engineer monitors the installation to see that lead does not exceed acceptable levels. (3)
  • Deal with project delays because essential pieces of equipment will be shipped late. Determine the consequences to project budgets and schedules and identify strategies, such as locating alternate vendors and accelerating other areas until the equipment arrives, to minimize the effects. (3)
  • Machine or equipment components do not fit together well. For example, an engineer in a manufacturing facility finds that bearings on a conveyor belt are looser than the desired push fit. The engineer determines the correct dimensions for the bearings, revises the drawings, makes note of design changes and notifies the millwrights and others who will be affected by the changes. (3)
  • Time and money has been lost when equipment malfunctions or fails to perform as expected. For example, following testing, mechanical engineers may determine that equipment is not performing as expected. They consult industry standards which describe potential problems that can be encountered, how to investigate them, potential solutions and remedial actions. They analyze data and formulate and investigate hypotheses to find the source of the problems. They re-design the equipment and conduct additional testing to demonstrate that the new pieces of equipment are of acceptable quality. (4)

Finding Information
  • Contact vendors or consult catalogues and websites to obtain equipment specifications, prices and delivery options. For example, search for information about pump capacities and prices of fans. (1)
  • Consult organizational intranets to access organization-specific information required for your work. For example, locate project work templates such as job initiation forms and job task numbers, reports of previous projects and lists of equipment inventories. (2)
  • Find technical information about materials and engineering methods. Consult colleagues and experts in other engineering disciplines. For example, consult colleagues with expertise in welding or parts manipulation to find information about unfamiliar applications or ask metallurgical engineers about the properties of alloys to determine which materials to use for projects. (3)
Back to Top

Critical Thinking
  • Judge the functionality or serviceability of equipment. Analyze evaluation data and apply International Organization of Standardization standards to calculate fault severities and consider codes such as the American Society for Mechanical Engineering, pipeline, structural steel codes, provincial boiler and pressure vessel acts and client limitations such as linguistic or financial barriers. Accurate judgments are vital to customer satisfaction and the credibility and profitability of the engineering firm. (3)
  • Judge the accuracy and completeness of mechanical engineering drawings before forwarding them for implementation. Ensure that the drawings adhere to required codes and standards and that the information is complete and presented in a clear and concise manner. Check that sufficient details have been provided for work to proceed. (3)
  • Conduct operations, environmental, safety and construction audits to assess quality, conformity with standards, safety and environmental risks. For example, conduct operational audits in manufacturing plants and construction sites to verify that the organizations meet all provincial and federal regulations. Also conduct environmental audits to check that organizations have spill containment procedures in place, that all tanks are double-walled and that organizations are following recycling and composting guidelines. Mechanical engineers' credibility will be damaged If they fail to think critically and their organizations can suffer serious consequences. (4)
