Testing times ahead

The National Physical Laboratory (NPL) has revealed a new study that shows how employees without training are ten times more likely to make measurement errors.   A new study co-ordinated by the National Physical Laboratory (NPL) and Coventry University shows measurements with procedures or guidance are up to ten times more accurate than those with little or no instruction. The study was based on 150 sets of data collected during a large-scale, two-day interactive measurement study carried out at the Coordinate Metrology Systems Conference (CMSC) recently. When using measuring equipment in any process it's important that the calibration status is known to ensure traceable measurements are obtained.  However there are currently no legal requirements for employees to receive accredited training to operate measuring equipment. Lack of standardised training leaves manufacturing processes exposed to human error and could lead to a decline in skills levels, impacting the future of the industry as a whole. To address these challenges, NPL, the UK's National Measurement Institute and one of the world's leading science and research facilities developing and applying the most accurate standards, science and technology available, in conjunction with Co-ordinate Metrology Society invited attendees to CMSC to participate in a study on how human behaviour impacts measurement. Professionals from a wide range of manufacturing sectors – including aerospace – took part in exercises exploring measurement strategies and behaviours. The measurement study was carried out over a two-day period where on day one the participants were invited to take a series of measurements with little or no instruction. Then on day two the participants were invited to complete the same measurements following set procedures. During each task the participants were monitored for their approach and behaviours in obtaining the measurement data. “To create an accurate reflection of how those being tested would react in their day to day role, we monitored methods and characteristics at four stages: pre-measurement, measurement planning, data collection (measurement) and post-measurement,” explains NPL's production development manager, Keith Bevan. “Measurement relies on key behavioural processes so it was important that the participant could communicate and relate to the requirements of each task, determine what was needed, apply these requirements to a strategy, be confident in the quality of the data obtained and be able to recognise and question any potential issues with the process.” Results of the study revealed that measurement variability without instruction was ten times more likely than when participants received strict guidance on the measurement strategy. This supports recommendations in the Government's Growth Review Framework for Advanced Manufacturing, that productivity improvements in manufacturing sectors could be achieved ‘through changes in working practices and processes... and improved skills'. NPL has developed a range of training courses which have been received globally by over 2,000 employees, encouraging learners to make a difference in their workplace. Business leaders from large blue chip organisations to SMEs have recognised the importance of investing in measurement training. “The manufacturing sector's contribution to the UK economy has declined by 40% in the past twenty years and business leaders must respond in order to remain competitive in growing global markets,” concludes Bevan. “Training through NPL allows manufacturing leaders to prepare for the future success of their business, now.” www.npl.co.uk
