Description
Summary:Purpose – Statistical thinking is an intrinsic part of the quality movement. Helped by initiatives such as Six Sigma, there is greater acceptance of the importance of data analysis and a general trend towards embracing numeracy. It is timely to review the emergence of statistical thinking and consider the good and bad features resulting from its application in a wide range of sectors. Design/methodology/approach – The paper first defines statistical thinking and justifies its importance to the quality movement. The achievements from the past 25 years are then considered sector by sector along with their collateral damage. Findings – The following lessons are proposed for the next 25 years: statistical thinking needs to expand its remit to include more aspects of analytical thinking becoming what may be called wider statistical thinking; statistical thinkers have ground-breaking ideas and need to communicate with managers at the top of the hierarchy to ensure that both the thinkers and the ideas have the influence they deserve; whilst learning from past successes, the quality movement must be mindful of knock-on effects and nurse a holistic viewpoint; expect the unexpected. Originality/value – Statistical thinking is gaining more prominence in all sectors and is used within the quality movement to make major progress as well as major upsets. It is important that the quality movement treads carefully and makes sure that society as a whole benefits from the ever increasing drive for improvement.
