Start by defining the desired outcome of the training. Odds are, you'll have more than one, so make a list. The design of your training should be tailored to match the needs of the task. Think about the characteristics a trainee will need to achieve acceptable performance; for example, how much knowledge a person needs versus how much skill must be obtained.
Create a training plan. A training plan will include the duration of the training, times the training will occur, a schedule showing when training activities are to begin and end. Your plan hinges on how well you are able to define the outcome. If the task is knowledge-intensive, make sure your plan is weighed towards teaching. Jobs that require a great deal of skill will demand hands-on activities and practice. Most subjects will require a little of both, but regardless, you will want to plan time for four critical activities in successful training: instruction, demonstration, replication and assessment.
Establish and track your training materials and documents. This is an important but often overlooked step in the training process. If you will be training multiple people over a period of time, then you must take this step very seriously. Remember, consistency is your goal, but without a clear record of how tasks must be completed various trainees might be trained differently, which will defeat your efforts. Keeping a record also helps you to see when processes may have changed and can be an important tool for identifying when retraining might be necessary. Finally, it will help reinforce training as a reference tool for trainees. Documents should thoroughly cover all details necessary for a regular person to complete the tasks and version histories are a good idea for tracking changes.
Include feedback with your design. Improving consistency in your training is as important as improving consistency in your trainee. Make sure you plan some time to evaluate your training as well as all your trainees' progress. Judge whether or not your goals were achieved and if not, what further action is needed.
