Lean Manufacturing has become one of those catch phrases that everyone understands and can immediately see the logic of, but evidence of consistently good results is hard to find. ‘Lean’ in Action within Food and Drink Manufacturing hilst the drive for efficiency improvements, within engineering sectors has been relentless there is still a long way to go within the UK food and drink manufacturing sector, yet this is one of the most vulnerable of all manufacturing sectors. This is broadly due to the intense competition between UK supermarkets, jostling for market share, whilst simultaneously demanding higher quality, total compliance, special offers, shorter batch runs and willing to accept few, if any, price increases from their ownlabel manufacturer/suppliers. W Contrast this with the fact that those same suppliers face ongoing demands for higher raw material and energy costs together with increased labour costs, and it is easy to see that any manufacturers, not fully committed to continuous improvement, are likely to struggle in the years ahead within such competitive environments. Lean Manufacturing has become one of those catch phrases that everyone understands and can immediately see the logic of, but evidence of consistently good results is hard to find. One reason for this is that, whilst the joint pressures of static sales prices and rising conversion costs are 44 PECM Issue 17 here now, some companies seem to imagine that continuous improvement or ‘Lean’ is something they can put off until next month/year/the year after. So many are too busy firefighting in order to get through today, to give appropriate thought to continuous improvement. Yet, most can see that, through continuous improvement, much of the need for firefighting will be systematically reduced. Most companies have already carried out their Value Stream Map to determine where they are adding value, where they are adding cost and perhaps have ideas about where they could reduce costs and add value, but this process needs to be constantly reviewed to ensure that gains made are sustained, whilst further improvements are made. In this regard, everything should be questioned, again and again, in pursuit of optimisation on the Lean journey. In addition, all mistakes and non-conformances that tie up so much time and cost in firefighting should be fully investigated so as to effectively eliminate the same problems recurring in future. So why do so many fires break out in the first place? Our own experience, over nearly four decad es, tells us that all factory floor conversion problems (why things don’t always turn out as intended) have their roots in just three things: • Loss of awareness (brief lapses of concentration) • Breaking the Rules (taking short cuts which actually turn out to be anything but) • Errors of Judgement (taking an educated guess instead of asking, or referencing SOPs) Any one of these might cause a problem but a combination could spell disaster, resulting in costly rework, scrap or batch rejection and loss of confidence. So, if these issues are the biggest enemies of Lean, how can they be avoided? So much of Food and Drink manufacturing control is still paper based and it’s easy to see how this has evolved. Paper is cheap and can be deployed anywhere within the supply chain, promptly and easily. Reliance upon paper recording however is fraught with limitations. Firstly it imposes little or no operational discipline and consequently little confidence that recorded tests were
