It also helps an organisation to identify who should, and who should not participate in specific training events. The immediate gains are motivated participants and enhanced job satisfaction. The longer term gains are the longer lasting effects of training, when needs have been addressed at the right time in the right way. Conducting a needs analysis is usually done to gauge what training is needed for new employees or to identify and find solutions to: performance problems, new systems, tasks or technologies and an organisation-wide need. In terms of methodologies, there are many tools that can be employed depending on the need to be analysed.  These range from researching existing data and evaluations, through to questioning and observation.  The data collected is analysed enabling informed decisions to be taken about what to do next to improve human or organisational conditions and performance.
